PearnContracts
Addresses, API and events.
Aurora testnet (1313161555)
PearnMarkets, StNearRateOracle and their libraries are verified on Blockscout; stNEAR and wNEAR are the bridged tokens.
| Contract | Address |
|---|---|
| PearnMarkets | 0x4659f0d99587D4fA396840d982a4215FcFe8a557 |
| StNearRateOracle | 0xA8adEFE2C8f0F71a585a73c1259997f593F9e463 |
| stNEAR (bridged) | 0x2137df2e54abd6bF1c1a8c1739f2EA6A8C15F144 |
| wNEAR (bridged) | 0x4861825E75ab14553E5aF711EbbE6873d369d146 |
Amounts are raw units, 1e24 per token. Contracts never call decimals(): bridged tokens on testnet report empty metadata.
PearnMarkets
| Function | Who |
|---|---|
createMarket(string question, uint64 closeTime, address resolver) → id | anyone |
bet(uint256 id, Side side, uint128 amount) | anyone, before close (approve stNEAR first) |
sponsor(uint256 id, uint128 amount) | anyone, until resolved |
resolve(uint256 id, Outcome outcome) | the market's resolver, after close and a post-close sync |
voidExpired(uint256 id) | anyone, 7 days after close |
overrideInvalid(uint256 id) | the guardian, within 24 h of resolution |
claim(uint256 id) → amount | bettors after the window; sponsors only when nobody bet |
