Technical documentation

Contracts live in /contracts (Foundry). Local lifecycle, yield, stress, fuzz and invariant tests cover proposed terms. No deployment or audit has occurred.

Production blockers

  • BLOCKEDLYRO contracts not deployed

    Contracts are written and tested locally, but no testnet or mainnet deployment has been made.

  • BLOCKEDBTC/USD and USDG/USD oracle feeds not verified

    Feed proxy addresses on chain 4663 must come from Chainlink's official directory.

  • BLOCKEDNo verified USDG → cbBTC execution route

    No router/pool with measured depth has been allowlisted.

  • BLOCKEDExit liquidity not validated

    Historical supply is not executable liquidity. Current size-dependent USDG exit quotes, depth and stress execution are unverified.

  • BLOCKEDProposed 80% LTV is not production validated

    A 12.5% price drop reaches the threshold from 70% initial LTV. Gap-downs, oracle latency and limited exit capacity can cause losses.

  • BLOCKEDPool entry-timing economics need independent review

    New shares may participate in subsequently collected interest accrued before entry. No epoch-based entitlement system has been validated.

  • BLOCKEDNo independent audit

    No external audit has been performed.

  • BLOCKEDLegal / regulatory review pending

    Lending, consumer-finance and securities requirements have not been assessed.
