Execute a write transaction on a smart contract via your Thirdweb Engine. Queues the transaction and returns a queueId for tracking. Use get-transaction-status to poll for confirmation. Ideal for: state-changing contract calls, token transfers, minting.

Send a raw transaction via your Thirdweb Engine. Takes pre-encoded calldata, destination address, and value. Queues the transaction and returns a queueId. Ideal for: arbitrary contract interactions, value transfers, custom calldata not covered by write-contract.

List all backend wallets configured in your Thirdweb Engine instance. Returns wallet addresses, types, and labels. Ideal for: discovering available wallets, populating wallet selection dropdowns, verifying wallet setup.

Check the status of a queued transaction on your Thirdweb Engine. Returns current status, transaction hash (once sent), and on-chain result (once mined). Ideal for: polling after a write-contract or send-transaction action, workflow conditions on tx status.

Read data from a smart contract via your Thirdweb Engine instance. Calls a read-only function and returns the result. Ideal for: checking balances, reading state, fetching on-chain data for workflow conditions.
