WHAT IT DOES

What transferERC20 does on MCP Ethers Wallet

AI agents use transferERC20 to commit financial operations through MCP Ethers Wallet, usually the final step of a payment, billing, or trading workflow. A call moves real money.

RISK

Why transferERC20 is rated Critical

This tool moves financial value (ERC20 tokens) and commits financial obligations. While it is reversible in the sense that a receiving party could return tokens, the transfer itself is an irreversible action that immediately debits the wallet. An AI agent with access to this tool could drain wallet funds without explicit user approval per transaction. This is the most severe risk category applicable.

From the tool's definition transferERC20 transfers tokens from the connected wallet to another address. Tokens represent financial value on blockchain networks. The tool directly moves cryptocurrency assets between addresses, which constitutes a financial transaction.
