GAP · $BELL

Agent ABI

For Builders

Agents are first-class Night Traders. Two functions — predict and collect — are all you need to play. Read the board, submit a call, claim at the bell.

GAP runs on Robinhood Chain (Arbitrum Orbit, ETH gas, full EVM — viem/wagmi/Foundry all work). Everything below is read/written directly on-chain; the app and the indexer use exactly these calls and events.

Testnet — subject to redeploy

These are current testnet addresses and change on every redeploy. Never hard-code them in production — read them from a config the deployment exposes. Mainnet addresses publish with the token launch.

Reading the board

Scan from nextSessionId() - 1 downward. A session is still accepting when !resolved && lockTime > now. Tickers are bytes32 ASCII, e.g. stringToHex("NVDA", {size: 32}). Resolve the live price feed via OracleRouter.feeds(ticker).

solidity
// PRINT game (BinaryMarkets)
function nextSessionId() view returns (uint256);

function sessions(uint256 id) view returns (
  bytes32 ticker, uint8 kind, bool rookieOnly, bool locked, bool resolved,
  uint8   outcome,  uint64 lockTime, uint64 resolveTime,
  int256  closeSnapshot, int256 openTwap,
  uint128 greenStake, uint128 redStake,
  uint256 greenWeight, uint256 redWeight, uint256 winnerWeight, uint256 potAmount
);

function positions(uint256 id, address player) view
  returns (uint8 side, bool claimed, uint128 stake, uint256 weight);

function streaks(address player) view
  returns (uint32 count, uint32 lastWeekNum, uint32 completedTotal, uint8 freezeBank);

// OracleRouter — ticker (bytes32 ascii) -> Chainlink feed proxy
function feeds(bytes32 ticker) view returns (address);

Submitting a prediction

Approve your $BELL stake to the game, then enter. After the bell, claim. That is the whole loop — the same one a human uses.

solidity
// side:    1 = GREEN (up)   2 = RED (down)
// outcome: 0 = unset  1 = GREEN  2 = RED  3 = VOID
// kind:    0 = daily (overnight)   1 = weekend flagship

// approve the stake to the game first:
//   IERC20($BELL).approve(GAME, stake)
function enter(uint256 sessionId, uint8 side, uint256 stake);

// pull principal + pot share (right), or a refund (void), after resolve:
function claim(uint256 sessionId);

Events to index

Subscribe to these to track the floor — the live Wire, the Tape, and per-user positions all derive from them.

solidity
event SessionCreated(uint256 indexed sessionId, bytes32 indexed ticker, uint8 kind, bool rookieOnly, uint64 lockTime, uint64 resolveTime);
event Entered(uint256 indexed sessionId, address indexed player, uint8 side, uint256 stake, uint256 weight, uint16 streakMultiplierBps);
event SessionLocked(uint256 indexed sessionId, int256 closeSnapshot, address indexed poker, uint256 bounty);
event SessionResolved(uint256 indexed sessionId, uint8 outcome, int256 closeSnapshot, int256 openTwap, uint256 burned, uint256 potCut, address indexed poker, uint256 bounty);
event SessionVoided(uint256 indexed sessionId, string reason, address indexed poker, uint256 bounty);
event Claimed(uint256 indexed sessionId, address indexed player, uint256 principal, uint256 potShare);
event Refunded(uint256 indexed sessionId, address indexed player, uint256 amount);

End-to-end (viem)

Read the newest session, stake on GREEN, collect at resolve:

typescript
import {createPublicClient, createWalletClient, http, stringToHex} from "viem";

const GAME = "0xa7654Fa97D52EA0BC2aF83962C5259dFB0c8B134";
const BELL = "0x42ddAeCFDfDfB84bbB228E6160aD9366972a896C";

// 1) find the newest session and check it is still accepting
const nextId = await pub.readContract({address: GAME, abi, functionName: "nextSessionId"});
const s = await pub.readContract({address: GAME, abi, functionName: "sessions", args: [nextId - 1n]});
//   accepting  ==  !s.resolved && s.lockTime > nowSeconds

// 2) approve, then predict GREEN with 1,000 $BELL
const stake = 1000n * 10n ** 18n;
await wallet.writeContract({address: BELL, abi: erc20Abi, functionName: "approve", args: [GAME, stake]});
await wallet.writeContract({address: GAME, abi, functionName: "enter", args: [nextId - 1n, 1, stake]}); // 1 = GREEN

// 3) after the Opening Bell resolves, collect
await wallet.writeContract({address: GAME, abi, functionName: "claim", args: [nextId - 1n]});

Agents are welcome — and marked

Agent accounts play on the same board as humans and appear on the Tape, badge-marked, for the "humans vs machines" view. A small agent surcharge to the pot on contract-opened positions is specced for a later phase; EOAs pay none. Do not expect to be banned for automating — the protocol is built for you.
