TidalYield is an automated yield-rotation protocol that surfs liquidity between top lending markets (Aave, Compound, Morpho, Spark) based on real-time APY tides. Core features: - **Tidal Vaults**: Deposit a single asset (USDC, ETH, wstETH) and the vault auto-rebalances across whitelisted lending markets every epoch (4h) when the APY delta exceeds a configurable threshold (default 25 bps, net of gas). - **Risk-banded strategies**: Three vault flavors per asset — Calm (blue-chip markets only), Swell (includes Morpho Blue isolated markets), and Storm (includes pendle PT loops). Each band has its own oracle and depeg circuit breaker. - **On-chain APY oracle**: Aggregates utilization curves directly from source contracts; no off-chain feeds, no keeper trust assumptions. - **TIDE token**: Governance + fee switch. 10% of yield routed to the protocol treasury, with veTIDE lockers directing emissions toward preferred vaults (Curve-style gauge). - **Looped LST strategy**: Optional sub-vault that loops wstETH on Aave v3 up to 5x leverage with an automated deleveraging trigger if the wstETH/ETH peg drifts beyond 50 bps. Stack: Solidity 0.8.24, Foundry, OpenZeppelin v5, ERC-4626 vaults, Chainlink price feeds for circuit breakers, Permit2 for gasless deposits. Deploys to Ethereum mainnet, Base, and Arbitrum.
