FAQ
Is this official? No. It is an independent community project, not affiliated with Papertrade.
Can the MCP server trade for me? No. It can quote, read and build unsigned payloads. You sign in your own wallet.
How accurate is the settlement math? liquidationPriceRaw matched 205 of 205 live bust prices, estimateClose reproduced 15 of 15 leaderboard wins plus a loss and a liquidation, and staking rewards match the contract to the wei. npm run test:live re-checks production.
Why is the EIP-712 domain name String? Because that is what the deployed exchange uses. A mainnet signature only verifies under that name. Do not change it.
Why do I get CORS errors in the browser? exchange.papertrade.xyz sends no CORS headers. Use a same-origin proxy and set baseUrl. This site ships one.
Why is my quoted profit lower than price move times notional? Wins lose a deadband, an impact haircut and a 2% fee. Use estimateClose or papertrade_estimate_position.
Why is longOiRaw not a dollar amount? OI is stored as base-asset quantity. Multiply by the mark with openInterestUsd.
Can a session key withdraw? No. Only the wallet can withdraw, stake, unstake or claim.
My client says the server does not support SSE. It does not open server-initiated streams; every call is a plain POST. Clients that require a GET stream still work because they fall back after the 405.
