Custom signing

Inspect and manually sign intent messages

Use getTransactionMessages to extract the raw typed data messages from a prepared transaction. This gives you full control over the signing process.

Custom signing is useful when you need to implement custom signing flows (e.g. sign async with each owner, use a custom signing method, etc).

Example

// 1. Prepare the transaction
const transactionData = await rhinestoneAccount.prepareTransaction({
  // …
});

// 2. Extract messages
const { origin, destination } =
  rhinestoneAccount.getTransactionMessages(transactionData);

// 3. Sign each message
const originSignatures = await Promise.all(
  origin.map((message) => sign(message)),
);
const destinationSignature = await sign(destination);

// 4. Submit the transaction
const transaction = await rhinestoneAccount.submitTransaction({
  ...transactionData,
  quote: transactionData.quotes.best,
  originSignatures,
  destinationSignature,
  targetExecutionSignature: undefined,
});
