ENS: pintel.eth on Sepolia

Architecture

Protocol Integrations

• Yellow Network — Off-chain order book for secondary position trading via ERC-7824 state channels
• ENS — Subname registration (*.pintel.eth) and text records for market indexing and trader reputation
• Chainlink — Price feed oracles for settlement and Automation keepers for trustless market resolution at expiry

Contract Functions

PintelMarketFactory

Function	Description
createMarket(params)	Deploy a new prediction market as an ERC-1167 clone with ENS subname
getAllMarkets()	Returns all deployed market addresses
getMarketsByCreator(address)	Returns markets created by a specific address
userStats(address)	Returns trader reputation: wins, totalClaims, totalPayout
syncReputationToENS(bytes32)	Writes trader stats to ENS text records
updateMarketRecords(bytes32)	Updates market ENS records (totalPool, status, positionCount)
recordResolution(bytes32)	Records final outcome to ENS after market resolves
recordClaim(address,uint256,bool)	Updates trader stats after a claim

PintelMarket

Function	Description
openPosition(mu, sigma, collateral)	Open a Gaussian position with predicted mean, confidence, and stake
closePosition(positionId)	Withdraw collateral before market ends
transferPosition(positionId, newOwner)	Transfer position ownership to another address
claim(positionId)	Claim payout after market is resolved
resolve(outcome)	Oracle-only: resolve market with final outcome value
question()	Returns the market question string
getActivePositionCount()	Returns number of active positions
getMarketDistribution()	Returns aggregate (mu, sigma) across all positions
positions(id)	Returns full position data: owner, mu, sigma, collateral, active, claimed

ChainlinkResolver

Function	Description
registerMarket(market, priceFeed)	Register a market with its Chainlink price feed
resolveMarket(market)	Resolve a single market using live Chainlink price
batchResolve(markets)	Resolve multiple expired markets in one tx
checkUpkeep(checkData)	Chainlink Automation: checks if any markets need resolving
performUpkeep(performData)	Chainlink Automation: resolves eligible markets
