RISK

Why send_self_custody_transaction is rated Critical

Despite the empty description, the tool name unambiguously suggests sending a blockchain transaction from a self-custody wallet. In the context of a ledger/payments server with wallet and bridge capabilities, this almost certainly moves cryptocurrency or digital assets, which constitutes a financial action. Self-custody transactions are irreversible on-chain, making misuse critical in severity.

From the tool's definition Tool name 'send_self_custody_transaction' combined with server context: 'wallet, payments, staking, bridges' — 'send' and 'transaction' strongly imply movement of funds from a self-custody wallet.
