## Why transfer_nft is rated Critical

NFT transfers on a blockchain are irreversible asset movements with financial value. The server context explicitly lists NFT operations and crypto transfers. While the description is empty (lowering confidence), the tool name and server context strongly imply an on-chain NFT transfer, which commits a financial asset. Financial > Destructive applies here as it moves a valuable asset permanently.

From the tool's own definition: "Tool name 'transfer_nft' on a server described as handling 'multi-chain crypto operations: transfers, token management, DeFi, NFT, smart contracts'. NFT transfers move blockchain assets irreversibly between addresses."

## Use case

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