WHAT IT DOES

What dex_swap does on Waiaas

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

RISK

Why dex_swap is rated Critical

A DEX swap directly exchanges one cryptocurrency asset for another, committing financial value. This is a Financial category action. Misuse could result in loss of funds through unfavorable trades, sandwich attacks, or draining a wallet. The server context (multi-chain crypto operations, spending limits, human approval mechanisms) confirms this is a real financial operation.

From the tool's definition 'Execute DEX swap' - performs a decentralized exchange swap, which is a financial transaction moving crypto assets
