Versioned transaction

A Solana transaction message marked with a format version so clients can interpret its structure correctly.

PLAIN-ENGLISH DEFINITION

In more detail

Versions can change how accounts and resource settings are represented. Wallets, RPC readers and indexers need support for the transaction's version to build or decode it correctly.

IN THE WILD

How you might use it
