signTransaction()

Overview

Signs a transaction using the specified wallet account.

Behavior differs depending on the type of wallet:

• Connected wallets
• Ethereum: does not support raw transaction signing. Calling this function will throw an error instructing you to use signAndSendTransaction instead.
• Solana: supports raw transaction signing via the connected wallet provider.
• Other chains: not supported; will throw an error.

• Embedded wallets
• Delegates signing to the Turnkey API, which returns the signed transaction.
• Supports all Turnkey-supported transaction types (e.g., Ethereum, Solana, Tron).
• Optionally allows stamping with a specific stamper (StamperType.Passkey, StamperType.ApiKey, or StamperType.Wallet).
