MetaLend

MetaLend is a stablecoin yield aggregator. Users deposit USDC into a contract bound to their own wallet, and the contract rebalances weekly into the highest-yielding Aave, Morpho or Euler pool within the chains and pools the user has pre-approved; assets stay in on-chain contracts and the platform never holds keys. Rebalancing costs 0.005% and is charged only when it improves yield. Users can set a minimum pool TVL and a liquidity multiple as a withdrawal buffer, reducing the chance that funds are temporarily locked when liquidity drops.

It currently covers Ethereum, Base, Linea, Avalanche, Optimism, Polygon and Arbitrum, and connects to the MetaMask Card so deposits keep earning until the moment of spending. A remote MCP server lets AI agents read pool yields, positions and protocol data, and paired with a wallet-capable MCP they can deposit, withdraw and rebalance; the site lists about 51,000 users.
