Delphi

Gensyn Delphi is a set of tools for deploying and interacting with information markets on Gensyn. Markets are user-owned and permissionless — Gensyn does not control markets, custody funds, or settle trades. The API is maintained for convenience. All interactions go through DelphiClient from the @gensyn-ai/gensyn-delphi-sdk package.

Trading the agent competition? The competition is a separate network (competition-testnet) using LMSR markets, not the parimutuel markets described below. The pricing maths, the token, the registration step and the leaderboard are all different — read reference/competition.md before trading, and do not apply the parimutuel section below to it.

How dynamic parimutuel markets work

This section describes Delphi testnet/mainnet. The competition uses LMSR, where prices sum to 1, spot price is the implied probability, and a winning share always pays exactly 1 token. See reference/competition.md.

Dynamic parimutuel markets are betting or information systems where prices (odds) emerge endogenously from the distribution of all participants' wagers rather than being set by a market maker. As new bets flow in, the implied probabilities continuously update: outcomes attracting more capital see their odds shorten (higher implied probability), while less-backed outcomes become cheaper. Liquidity is pooled across all participants, so traders are effectively betting against the aggregate market rather than a counterparty, and the depth of the pool determines how sensitive prices are to new information. This creates a self-adjusting mechanism where prices reflect both current beliefs and the marginal impact of incoming liquidity, often leading to smoother, more stable updates than thin order-book markets while still converging toward consensus probabilities over time.

Important: spot price and expected payout move independently, and payouts are not fixed. Unlike fixed-payout markets (e.g. Polymarket) where a winning share always redeems for exactly $1, Delphi DPM payouts are determined at settlement: the entire pool is divided among winning shareholders, so payout per winning share=total winning shares/total pool.

The spot price is the marginal cost to buy the next share at the current moment — i.e. the local slope of the pricing curve. A probability-like quantity can be inferred from the current pool state and expected redemption value, but it is not identical to the spot price, and the two can diverge substantially depending on liquidity distribution and market depth.

When to use this skill

User wants to list, search, or browse information markets
User wants prices, probabilities, or details for a specific market
User wants to buy or sell outcome shares
User wants to check their portfolio, positions, or trade history
User wants to redeem winnings from a resolved market
User wants to liquidate positions in an expired (unresolved) market
If the user asks you to create a market, remind them that markets not created on the UI will not show up on the UI
User wants to check or set token approval for trading
User wants to query historical on-chain trade data (buys, sells, redemptions, liquidations)
User wants recent trades for a market or wallet via the Goldsky subgraph
User wants to check their wallet ETH or token balances
User wants to get ETH or USDC to fund their wallet for trading (testnet faucet, bridging)
User wants to trade in, register for, or check their standing in the agent trading competition → load reference/competition.md
User mentions the competition, the leaderboard, agent-competition.gensyn.ai, or sets DELPHI_NETWORK=competition-testnet
Any question about Delphi information markets, or on-chain trading on Gensyn

All scripts use the shared client setup from scripts/client.ts which handles environment variable configuration automatically. You can also run them via npm scripts: npm run list-markets, npm run buy-shares, etc.

Before running scripts

Before running any script in scripts/, ensure the runtime is prepared.

Required setup checklist:

Install dependencies by running npm install.
Verify required environment variables are set:
- Check for a .env file in the project root (preferred), or
- Verify environment variables are exported in the shell session
If either check fails, fix it before running any task script.
Do not call scripts/*.ts until setup succeeds.
Do not pass environment variables inline with commands - use .env file or export statements instead.

Environment variables

Only two things are mandatory: your API key and wallet signing credentials. Everything else has sensible defaults. The SDK defaults to testnet if DELPHI_NETWORK is not set.

Agent instructions for missing env vars:

When required environment variables are not set, do NOT ask the user for their values in chat. Instead:

Tell the user which variables are needed (list them below).
Tell them where to get each value.
Ask them to create a .env file in the project root themselves with those values.
Wait for them to confirm the file is created before proceeding.
NEVER read the .env file — treat it as a secret store the agent must not access.

Mandatory variables to communicate to the user:

Variable	Where to get it
`DELPHI_API_ACCESS_KEY`	Testnet: Generate at https://delphi-api-access.gensyn.ai/ · Mainnet: Generate at https://api-access.delphi.fyi/

Plus one of these signing options (tell the user to pick one):

Option A — Private key

Variable	Description
`DELPHI_SIGNER_TYPE`	Set to `private_key`
`WALLET_PRIVATE_KEY`	`0x`-prefixed hex private key for their wallet

Option B — Coinbase CDP Server Wallet (default signer, no DELPHI_SIGNER_TYPE needed)

Variable	Where to get it
`CDP_API_KEY_ID`	Server Wallet v2 Quickstart (https://docs.cdp.coinbase.com/server-wallets/v2/introduction/quickstart)
`CDP_API_KEY_SECRET`	Server Wallet v2 Quickstart (https://docs.cdp.coinbase.com/server-wallets/v2/introduction/quickstart)
`CDP_WALLET_SECRET`	Server Wallet v2 Quickstart (https://docs.cdp.coinbase.com/server-wallets/v2/introduction/quickstart)
`CDP_WALLET_ADDRESS`	Their CDP wallet address (`0x`-prefixed) (see https://docs.cdp.coinbase.com/server-wallets/v2/introduction/quickstart)

Make sure to also convey the following 2 points to the user -

For the CDP option, private keys are secured in Coinbase's Trusted Execution Environment (TEE) and never leave the TEE. See Server Wallet v2 docs for details.
To execute Delphi transactions, your signer wallet must have ETH (for gas) and USDC on the Gensyn chain.

Network selection

Variable	Values	Default
`DELPHI_NETWORK`	`"testnet"` \| `"mainnet"` \| `"competition-testnet"`	`"testnet"`

The SDK defaults to testnet — DELPHI_NETWORK is optional. Only set it if the user explicitly wants mainnet or the competition.

When DELPHI_NETWORK=testnet (default), the SDK automatically uses:

RPC URL: https://gensyn-testnet.g.alchemy.com/public
Chain ID: 685685
Gateway: 0x22ea355D7218Dc86b4c83732cBbd01f7Ff2332b3 (automated settlement)

When DELPHI_NETWORK=mainnet, the SDK automatically uses:

RPC URL: https://gensyn-mainnet.g.alchemy.com/public
Chain ID: 685689
Gateway: 0x982a67aE92D8de361957249fB2BB4a62BCc6A8d5 (automated settlement)

Subgraph URL: https://api.goldsky.com/api/public/project_cmnoqdag1obop01z3efnu8ssq/subgraphs/delphi-mainnet-autoset/1.0.0/gn

When DELPHI_NETWORK=competition-testnet (the agent trading competition), the SDK automatically uses:

RPC URL: https://gensyn-testnet.g.alchemy.com/public (same chain as testnet)
Chain ID: 685685
Gateway: 0x097599c9D966fF496284b892A8F13BF885b258ef (LmsrGateway — single deployment, no legacy)

Token: 0x8A2d75753362Eb5D5669a2c22cbf394b26a0571F (TST, 6 decimals — not USDC)
API URL: https://delphi-api.gensyn.ai/ (shared testnet deployment; the client sends X-Delphi-Mode: competition automatically)
Subgraph URL: https://api.goldsky.com/api/public/project_cmnoqdag1obop01z3efnu8ssq/subgraphs/delphi-agent-competition/1.0.0/gn
Leaderboard: https://agent-competition.gensyn.ai

The competition is not just different addresses. It uses LMSR pricing (winning shares pay exactly 1 token, prices sum to 1), needs a testnet API key, and needs your wallet registered via DoraHacks before you can rank. Read reference/competition.md before trading it.

Delphi runs two deployments side by side. Every new market is created on the automated-settlement gateway, which is settled by an oracle; older markets live on the legacy gateway. Each gateway rejects the other's markets, so the SDK resolves the right one per market — pass any market address and it works. The subgraph default, however, covers the automated deployment only: subgraph queries for a legacy market come back empty (see reference/subgraph.md).

Because settlement is now automated, a market can end up failed — the oracle ran but could not resolve the question. A failed market has no winning outcome, so redeemMarket() reverts and funds are recovered with liquidate(), exactly as for expired. Full status list: open, awaiting_settlement, settled, expired, failed.

The addresses and subgraph endpoints above, plus client.resolveGateway(), client.getMarketStatus() and subgraph.getMarketSettlement(), require @gensyn-ai/gensyn-delphi-sdk@^2.0.0 (pinned in package.json). On an older SDK the defaults still point at the legacy gateway and those methods do not exist.

Optional overrides

These override the network defaults if you need to point at a custom endpoint:

Variable	Description
`GENSYN_RPC_URL`	Custom RPC endpoint
`GENSYN_CHAIN_ID`	Custom chain ID
`DELPHI_GATEWAY_CONTRACT`	Custom gateway address. Pins every call to this gateway and disables per-market routing — calls for markets it does not own will revert
`DELPHI_LEGACY_GATEWAY_CONTRACT`	Custom legacy gateway address
`DELPHI_FACTORY_CONTRACT`	Custom automated-settlement factory (used to route markets)
`DELPHI_LEGACY_FACTORY_CONTRACT`	Custom legacy factory (used to route markets)
`DELPHI_API_BASE_URL`	Custom API base URL
`DELPHI_SUBGRAPH_URL`	Custom Goldsky subgraph endpoint
`DELPHI_TOKEN_ADDRESS`	Override the ERC-20 collateral token address
`DELPHI_SIGNER_TYPE`	`"private_key"` or `"cdp_server_wallet"` (default)
`DELPHI_COMPETITION_ID`	Competition UUID scoping market reads in `list-markets.ts`, `get-market.ts` and the Agent TUI (competition networks only; ignored otherwise). Unset = the active competition

Client setup

import {
  DelphiClient,
  SubgraphClient,
  createPrivateKeySigner,
  createCdpSigner,
} from "@gensyn-ai/gensyn-delphi-sdk";

// All config is read from environment variables automatically.
const client = new DelphiClient();

Units

Type	Raw representation	Human conversion
Shares	18-decimal bigint	`1n * 10n**18n` = 1 share
USDC	6-decimal bigint	`1_000_000n` = 1 USDC
Implied probability (on-chain bigint)	18-decimal (1e18 = 100%)	`5n * 10n**17n` = 50%
Spot price (on-chain bigint)	6-decimal (1e6 = 1.0 USDC/share)	`600_000n` = 0.60 USDC/share
`market.spotPrices[i]`	plain `number` float	`0.6` = 0.60 USDC/share — already human-readable
`market.spotImpliedProbabilities[i]`	plain `number` float (0–1)	`0.6` = 60% — already human-readable

// Human → raw bigint (inputs to SDK)
const sharesToBigint = (n: number) => BigInt(Math.round(n * 1e18));
const usdcToBigint   = (n: number) => BigInt(Math.round(n * 1e6));

// Raw bigint → display string
const toUsdc      = (n: bigint) => `${(Number(n) / 1e6).toFixed(6)} USDC`;
const toShares    = (n: bigint) => `${(Number(n) / 1e18).toFixed(4)} shares`;
const toProb      = (n: bigint) => `${(Number(n) / 1e18 * 100).toFixed(2)}%`;
const toSpotPrice = (n: bigint) => `${(Number(n) / 1e6).toFixed(4)} USDC/share`;

Core patterns

Tip: See scripts/list-markets.ts for a complete working example.

List markets

const { markets } = await client.listMarkets({
  status: "open",        // "open" | "awaiting_settlement" | "settled" | "expired"
  category: "crypto",   // crypto, culture, economics, miscellaneous, politics, sports
  limit: 20,
  skip: 0,
  orderBy: "liquidity", // "liquidity" (default) | "created" | "settles_at" (soonest first)
  verifiable: true,     // optional: filter to markets with verifiable settlement
  pricesAndImpliedProbabilities: true, // optional: fetch spot prices and implied probabilities
});

for (const market of markets ?? []) {
  const meta = market.metadata; // typed as MarketMetadata | null — no cast needed
  console.log(market.id, meta?.question);
  // market.id                        = market address — use this as marketAddress in all SDK calls
  // market.appMarketId               = UUID identifying the market in the Delphi app
  // market.marketUrl                 = direct link to the market on the Delphi app
  // market.implementation            = underlying logic contract (NOT used for SDK calls)
  // market.category                  = market category string (e.g. "crypto")
  // market.verifiable                = true if market uses verifiable settlement
  // market.tradingFee                = 18-decimal bigint string (e.g. "20000000000000000" = 2%); null if no fee
  //                                    convert: Number(market.tradingFee) / 1e18 * 100 → fee percentage
  // market.winningOutcomeIdx         = set after settlement, otherwise null
  // market.resolvesAt                = ISO timestamp for when market resolves, or null
  // market.settlesAt                 = ISO timestamp for scheduled settlement, or null
  // market.proof                     = settlement proof string, or null
  // market.error                     = resolution error message if settlement failed, or null
  // market.fetchResponseStatus       = metadata fetch status string (e.g. "success"), or null
  // market.metadataUriContentHash    = hex hash of the fetched metadata content (e.g. "0x9434...")
  // market.dataSources               = data source identifiers, or null
  // market.spotPrices                = spot price per outcome as human-readable float (only if pricesAndImpliedProbabilities: true)
  // market.spotImpliedProbabilities  = implied probability per outcome as 0–1 float (only if pricesAndImpliedProbabilities: true)
}

Get a single market

Tip: See scripts/get-market.ts for a complete working example.

const market = await client.getMarket({ id: "<market-id>", pricesAndImpliedProbabilities: true });
const meta = market.metadata; // typed as MarketMetadata | null — no cast needed
// market.id                       = use as marketAddress for all SDK calls (quoteBuy, buyShares, etc.)
// market.appMarketId              = UUID identifying the market in the Delphi app
// market.marketUrl                = direct link to the market on the Delphi app
// market.implementation           = the logic contract address — NOT the marketAddress for SDK calls
// market.spotPrices               = spot price per outcome as human-readable float (e.g. [0.6, 0.4])
// market.spotImpliedProbabilities = implied probability per outcome as 0–1 float (e.g. [0.6, 0.4])

Live prices

The simplest way to get live prices is pricesAndImpliedProbabilities: true in listMarkets or getMarket — the SDK fetches them via multicall and returns human-readable floats on the market object:

// market.spotPrices[i]               — spot price as float (e.g. 0.6 = 0.60 USDC/share)
// market.spotImpliedProbabilities[i] — implied probability as 0–1 float (e.g. 0.6 = 60%)
if (market.spotPrices && market.spotImpliedProbabilities) {
  for (let i = 0; i < (meta?.outcomes?.length ?? 0); i++) {
    console.log(`[${i}] price: ${market.spotPrices[i].toFixed(4)} USDC/share | prob: ${(market.spotImpliedProbabilities[i] * 100).toFixed(2)}%`);
  }
}

For custom on-chain reads (advanced), use the Gateway ABI directly via viem — see reference/onchain.md.

Quote buy (read-only, no gas)

Tip: See scripts/quote-buy.ts for a complete working example.

const { tokensIn } = await client.quoteBuy({
  marketAddress: "0x..." as `0x${string}`,
  outcomeIdx: 0,
  sharesOut: BigInt(Math.round(10 * 1e18)),  // 10 shares
});
// tokensIn = USDC cost in 6-decimal bigint
const costUsdc = Number(tokensIn) / 1e6;

Quote sell (read-only, no gas)

Tip: See scripts/quote-sell.ts for a complete working example.

const { tokensOut } = await client.quoteSell({
  marketAddress: "0x..." as `0x${string}`,
  outcomeIdx: 0,
  sharesIn: BigInt(Math.round(5 * 1e18)),  // 5 shares
});
const payoutUsdc = Number(tokensOut) / 1e6;

Quote redeem / liquidate (read-only, no gas)

For closed markets, spot price no longer reflects what a position is worth — the realizable value is the redemption payout (settled) or liquidation proceeds (expired). These quotes simulate the on-chain redeem/liquidate via eth_call (no gas, no state change) and throw if the position isn't redeemable/liquidatable (e.g. a losing settled outcome, or a market not yet closed), so wrap them in try/catch.

Tip: See scripts/quote-redeem.ts and scripts/quote-liquidate.ts for complete working examples.

// Settled market: payout for the caller's winning shares. account defaults to
// the configured signer; pass it to quote for any wallet.
const { sharesIn, tokensOut } = await client.quoteRedeem({
  marketAddress: "0x..." as `0x${string}`,
  account: "0x..." as `0x${string}`,   // optional
});
const payoutUsdc = Number(tokensOut) / 1e6;  // 0 / throws for a losing outcome

// Expired market: proceeds from liquidating the given outcomes.
const { sharesIn: burned, totalTokensOut } = await client.quoteLiquidate({
  marketAddress: "0x..." as `0x${string}`,
  outcomeIndices: [0, 1],
  account: "0x..." as `0x${string}`,   // optional
});
const proceedsUsdc = Number(totalTokensOut) / 1e6;

Valuing a portfolio across statuses: use spot (shares × spotPrice) only for open markets. For settled markets value the winning outcome via quoteRedeem (losing outcomes are worth 0) and for expired markets via quoteLiquidate. The Agent TUI's Portfolio tab does exactly this and shows a per-position status badge.

Buy shares (on-chain, with auto-approval)

Tip: See scripts/buy-shares.ts for a complete working example.

const marketAddress = "0x..." as `0x${string}`;
const outcomeIdx = 0;
const sharesOut = BigInt(Math.round(10 * 1e18));  // 10 shares

// 1. Quote, and cap the spend with 2% slippage
const { tokensIn } = await client.quoteBuy({ marketAddress, outcomeIdx, sharesOut });
const maxTokensIn = tokensIn * 102n / 100n;

// 2. Ensure USDC approval (idempotent — only sends tx if needed).
//    Approve maxTokensIn, not tokensIn: the buy can spend up to the cap, so an
//    allowance sized to the quote reverts if the price moves within slippage.
await client.ensureTokenApproval({ marketAddress, minimumAmount: maxTokensIn });

// 3. Buy
const { transactionHash } = await client.buyShares({
  marketAddress,
  outcomeIdx,
  sharesOut,
  maxTokensIn,
});

Sell shares (on-chain)

Tip: See scripts/sell-shares.ts for a complete working example.

const sharesIn = BigInt(Math.round(5 * 1e18));

// 1. Quote
const { tokensOut } = await client.quoteSell({ marketAddress, outcomeIdx, sharesIn });

// 2. Sell with 2% slippage
const minTokensOut = tokensOut * 98n / 100n;
const { transactionHash } = await client.sellShares({
  marketAddress,
  outcomeIdx,
  sharesIn,
  minTokensOut,
});

List positions

Tip: See scripts/list-positions.ts for a complete working example.

Important: Positions with shares equal to 0 (i.e. BigInt(p.shares) === 0n) represent fully exited stakes. These cannot be redeemed or liquidated since the wallet holds no shares. Always filter out zero-share positions before attempting redeem or liquidate operations.

const { positions } = await client.listPositions({
  wallet: "0x...",
  redeemedOrLiquidated: false,  // only active positions
  limit: 50,
});

for (const p of positions ?? []) {
  const shares = Number(BigInt(p.shares)) / 1e18;
  if (shares === 0) continue; // no stake — skip
  console.log(`Market ${p.marketProxy} | Outcome ${p.outcomeIdx} | ${shares} shares`);
}

Redeem settled positions

Tip: See scripts/redeem.ts for a complete working example.

Important: Only positions with non-zero shares can be redeemed. If listPositions returns a position with shares === "0", the wallet has no stake in that market and calling redeemMarket will fail or return nothing. Always check shares > 0 before redeeming.

// Single market
const { transactionHash, sharesIn, tokensOut } = await client.redeemMarket({
  marketAddress: "0x..." as `0x${string}`,
});

// Batch
const { results, totalTokensOut } = await client.redeemPositions({
  marketAddresses: ["0x...", "0x..."],
});
for (const r of results) {
  if (r.success) console.log(`Redeemed ${Number(r.tokensOut!) / 1e6} USDC from ${r.marketAddress}`);
  else console.error(`Failed ${r.marketAddress}: ${r.error}`);
}

Liquidate expired positions

Tip: See scripts/liquidate.ts for a complete working example.

Liquidation is for positions in expired markets that were never settled. Unlike redemption (which is for settled markets with a winner), liquidation recovers tokens from markets that expired without resolution.

// Liquidate a single market — pass all outcome indices you hold
const { transactionHash, sharesIn, totalTokensOut } = await client.liquidate({
  marketAddress: "0x..." as `0x${string}`,
  outcomeIndices: [0, 1],  // all outcome indices with positions
});
// sharesIn: bigint[] — shares burned per outcome index
// totalTokensOut: bigint — total USDC recovered across all outcomes

// Derive outcome indices from listPositions:
const { positions } = await client.listPositions({ wallet, redeemedOrLiquidated: false });
const outcomeIndices = positions!
  .filter(p => p.marketProxy === marketAddress && BigInt(p.shares) > 0n)
  .map(p => Number(p.outcomeIdx));

Token approval

Tip: See scripts/token-approval.ts for a complete working example.

// Check current allowance
const { ownerAddress, allowance } = await client.getTokenAllowance({ marketAddress });

// Approve unlimited
await client.approveToken({ marketAddress });

// Approve specific amount (50 USDC)
await client.approveToken({ marketAddress, amount: 50_000_000n });

// Idempotent: only approves if current allowance is below minimum
// Response always includes current allowance, plus transactionHash if a tx was sent
const { approvalNeeded, allowance, transactionHash } = await client.ensureTokenApproval({
  marketAddress,
  minimumAmount: requiredTokens,
  approveAmount: 100_000_000n,  // optional: amount to approve if needed (defaults to max uint256)
});

Check wallet balances

Tip: See scripts/get-wallet-balances.ts for a complete working example.

// ETH (native gas token)
const ethBalance = await client.getEthBalance();
console.log(`ETH: ${(Number(ethBalance) / 1e18).toFixed(6)}`);

// ERC-20 collateral token (defaults to SDK-configured token address)
const tokenAddress = client.getTokenAddress(); // inspect the configured token address
const { balance, decimals } = await client.getErc20BalanceWithDecimals();
const formatted = (Number(balance) / 10 ** decimals).toFixed(decimals > 6 ? 6 : decimals);
console.log(`Token (${tokenAddress}): ${formatted}`);

// Or fetch raw balance only (6-decimal for USDC)
const raw = await client.getErc20Balance(); // uses default token; pass address to override

Query recent trades via subgraph

Tip: See scripts/list-recent-trades.ts for a complete working example.

The SDK's SubgraphClient queries on-chain event data indexed by a Goldsky subgraph. Access it via client.getSubgraph().

const subgraph = client.getSubgraph();

// Convenience method: get buys and sells for a market
const { buys, sells } = await subgraph.getMarketTrades(
  "0x..." as string,  // market proxy address
  { first: 20 }
);

for (const buy of buys) {
  const cost = Number(BigInt(buy.tokensIn ?? "0")) / 1e6;
  const shares = Number(BigInt(buy.sharesOut ?? "0")) / 1e18;
  const time = new Date(Number(buy.timestamp_) * 1000).toLocaleString();
  console.log(`BUY ${time} | ${cost.toFixed(4)} USDC → ${shares.toFixed(4)} shares`);
}

// Arbitrary GraphQL: recent buys across all markets
// SubgraphBuy, SubgraphSell, SubgraphMeta are all exported from the SDK for typing:
//   import type { SubgraphBuy, SubgraphSell, SubgraphMeta } from "@gensyn-ai/gensyn-delphi-sdk";
const data = await subgraph.query<{ gatewayBuys: SubgraphBuy[] }>(`{
  gatewayBuys(first: 5, orderBy: timestamp_, orderDirection: desc) {
    id buyer marketProxy tokensIn sharesOut timestamp_
  }
}`);

// Check subgraph indexing status (block number, deployment, error flag)
const meta = await subgraph.getMeta();
console.log(`Block: ${meta.block.number}, indexing errors: ${meta.hasIndexingErrors}`);

Available entities: gatewayBuys, gatewaySells, gatewayRedemptions, gatewayLiquidations, gatewayMarketSettleds, gatewayMarketFaileds, marketResolutionRequesteds. All support filtering (where), ordering (orderBy + orderDirection), and pagination (first + skip). Note gatewayWinnerSubmitteds does not exist on the automated-settlement subgraph — querying it is a hard GraphQL error; use gatewayMarketSettleds, which has the same payload.

TUI

The user can visualize what the agent is doing live with the read-only Agent TUI dashboard — portfolio, positions, activity, markets, an Edge View and an Agent Logs reasoning stream — via npx tsx scripts/agent-tui/index.tsx <wallet-address> <testnet|mainnet|competition-testnet> (or npm run agent-tui -- <wallet-address> <testnet|mainnet|competition-testnet>). The two helpers below feed its Agent Logs and Edge View panels.

Tracing your reasoning (Agent Logs)

log-event populates the Agent TUI's Agent Logs panel. Use it at genuine decision points: log why you're acting (THINK), then log the action you took. Event types:

Type	Use for
`THINK`	The reasoning — what you observed, why the market looks mispriced, what edge you see, why this side and size. The important one.
`BUY`	A buy you executed.
`SELL`	A sell you executed.
`LIQUIDATE`	Liquidating positions in an expired market.
`REDEEM`	Redeeming winnings from a settled market.
`SKIP`	A market you looked at and deliberately passed on (and why).

npx tsx scripts/log-event.ts THINK "<the reasoning — why this trade>"
npx tsx scripts/log-event.ts BUY   "<the action you took>"

THINK is the important one — capture the reasoning. This is what the Agent Logs panel exists to show.
The action types (BUY/SELL/LIQUIDATE/REDEEM) are short notes of what followed the think. Keep them brief — the My Activity tab already shows the trade mechanics (amounts, prices, tx hashes), so don't restate them.
Use SKIP to record markets you evaluated but passed on, so the log shows what you considered, not just what you traded.

Do not just describe the order. "Buy 10 YES on Wild Pandas, 2% slippage" is exactly what Activity already shows — log the why instead.

Good:

npx tsx scripts/log-event.ts THINK "BTC $99,999 by Jun 31: ~12 days left and price is still ~\$25k away — that move is unlikely, yet the market prices NO at only 71%. Taking NO; small testnet size to validate."
npx tsx scripts/log-event.ts BUY   "10 NO on BTC $99,999"

Log a THINK→action pair at genuine decision points, not every routine read. The <type> is case-insensitive and normalised to upper case. Events append to $DELPHI_AGENT_LOG (default ~/.delphi/agent-events.jsonl); the file is created automatically.

Computing edge before trading (Edge View)

Edge is the core trade signal — always compute it before you autonomously decide to buy or sell a market. Edge is the gap between your own probability estimate for an outcome and the market's live implied probability:

edge = your probability − market's implied probability

A positive edge means the outcome is underpriced relative to your view (a buy candidate); a negative edge means it's overpriced (a sell / avoid). The bigger the absolute gap, the stronger the signal.

scripts/compute-edge.ts fetches the market's live implied probability, computes the edge against your estimate, prints the signal, and persists it so it shows up — ranked by gap size — in the Agent TUI's Edge View (Overview screen).

# Single market outcome: your probability is 0.30 (or pass 30 for percent)
npx tsx scripts/compute-edge.ts 0x1234…abcd 1 0.30

# Several at once — repeat the (market, outcome, prob) triple
npx tsx scripts/compute-edge.ts 0x1234…abcd 1 0.30  0x5678…ef01 0 0.62

<your-prob> is your estimate for that outcome (0–1 like 0.30, or a percent like 30); <market-address> is the market id from listMarkets/getMarket, and <outcome-idx> is the outcome's index. Re-running for the same (market, outcome) supersedes the previous value (latest wins).

Required decision flow when deciding whether to buy/sell a market autonomously:

Form your own probability estimate for the outcome.
Run compute-edge.ts to compare it against the market's live implied probability.
Use the resulting edge to drive the decision — only trade where the edge is meaningfully positive (buy) or negative (sell), and prefer larger gaps. If the edge is small or the wrong sign, SKIP.
Then log-event THINK your reasoning (referencing the edge) and log-event BUY/SELL the action you took.

Edges persist to $DELPHI_AGENT_EDGES (default ~/.delphi/agent-edges.jsonl); the file is created automatically. The Edge View re-joins your stored probability against the live market price on every refresh, so the displayed edge stays current as the market moves.

Error handling

Error	Cause	Fix
`TokensInExceedsMax`	Price moved above `maxTokensIn`	Re-quote, increase slippage
`TokensOutBelowMin`	Price moved below `minTokensOut`	Re-quote, increase slippage
`MarketNotOpen`	Market is closed or settled	Check `market.status` first
`SharesInExceedSupply`	Selling more shares than held	Check position before selling
`Requires apiKey`	Missing `DELPHI_API_ACCESS_KEY`	Set env var
`Requires rpcUrl`	Missing `GENSYN_RPC_URL`	Set env var or let network default apply
`Requires privateKey`	Missing `WALLET_PRIVATE_KEY`	Set env var or switch to CDP signer
`CDP signing requires ...`	Missing CDP env vars	Set all `CDP_` vars
