Verify a Transaction

Verify that an XL1 transaction reached finalized chain state.

A returned transaction hash proves submission, not finality. Verify the transaction through the SDK viewer and finalized chain state.

const transaction = await gateway.connection.viewer?.transaction.byHash(transactionHash)

Check all of the following:

• the viewer returned a transaction for the expected hash;

• the signer and network match the user-approved operation;

• the expected payload hashes and schemas are present;

• the containing block is finalized; and

• every dereferenced application payload passes your schema validator.

Use ExplorerLinks from @xyo-network/xl1-sdk when presenting a human-readable explorer link. Do not hand-build explorer URLs.
