t1 Documentation

t1 is the permissionless credit protocol for DeFi. Lenders extend undercollateralized loans to anyone, and get repaid without a legal agreement, a custodian, or a pile of idle collateral. This is possible thanks to:

  • Programmable custody: Each borrower gets a margin account whose private key lives in a Trusted Execution Environment (TEE) and signs only the transactions their loan policy permits. The borrower can direct the capital and can never take it.
  • Real-Time Proving: Positions held on separate venues and chains resolve into one margin account, from state that is proven rather than reported.

Together they put leverage on venues no smart contract can reach: prediction markets and memecoins.
