// UnblockEquity yield adapter for DefiLlama yield-server
// 24 MetaMorpho V2 vaults on Base — USDC lending against tokenized residential property liens.
//
// TVL : live totalAssets() per vault (ERC4626), summed via SDK multicall.
// APY : live supply APY computed from each market's Morpho Blue IRM:
// supply APY = (1 + borrowRatePerSec)^(secondsPerYear) - 1, scaled by
// utilization × (1 - fee). Mirrors Morpho's own SDK math.
// Vaults are NOT yet whitelisted in Morpho's GraphQL API, so this
// adapter goes directly to chain via DefiLlama SDK.
