Withdraw tokens from a user's Otto AI Safe to any EOA. Supports 7 chains (Base, Polygon, Arbitrum, Ethereum, BSC, Avalanche, Solana). Non-Base chains require an explicit EOA recipient.

Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
