Supply/lend assets to HyperLend protocol lending pools on Hyperliquid EVM network to earn lending yield and enable borrowing capacity
AI agents use hyperevmSupply to commit financial operations through HyperEVM MCP — usually the final step of a payment, billing, or trading workflow. A call moves real money.
This tool moves real financial assets into a DeFi lending protocol on a live EVM network. Supplying assets commits funds to a smart contract, changing the user's asset holdings and financial position. This constitutes a financial operation with high blast radius if misused, as assets could be locked or lost due to protocol risks, incorrect amounts, or wrong pool selection.
