Transaction v1

The plugins build version 1 transactions by default. Version 1 raises the maximum transaction size from 1232 to 4096 bytes and carries the compute unit limit, loaded accounts data size limit, and priority fee in the message config instead of ComputeBudget instructions. Both limits default to zero, so the plugins estimate whichever one you leave unset.

Version 1 needs a cluster with the txv1 feature gate active (mainnet, devnet, testnet, and solana-test-validator 4.2+) and cannot use address lookup tables. Pass version: 0 to opt out:

• @kit-helpers/transaction-builder — transactionBuilderPlugin({ version: 0 })
• @kit-helpers/action — actionPlugin({ version: 0 }), or version per call
• @kit-helpers/client — createSolanaClient({ version: 0, ... })
• @kit-helpers/wallet — client.wallet.supportedTransactionVersions reports which versions a connected wallet will sign; the action namespace builds version 0 for a wallet that does not advertise version 1

Priority fee units differ by version: version 0 takes a price per compute unit, version 1 a total in lamports. Passing the wrong option throws.

Reading transactions back requires maxSupportedTransactionVersion: 1 on getTransaction and getBlock; a version 1 transaction's limits appear under transactionConfig. See SIMD-0296 and SIMD-0385.
