# getSignaturesForAddress - Solana

Example code for the getSignaturesForAddress JSON-RPC method. Complete guide on how to use the getSignaturesForAddress JSON-RPC method in the GetBlock Web3 documentation.

This method returns confirmed transaction signatures that reference a given address, ordered from newest to oldest. Results are paginated with the `before` and `until` cursors.
