# Interface: TransactionPayload

Defined in: [packages/bitbadgesjs-sdk/src/transactions/messages/base.ts:117](https://github.com/BitBadges/bitbadgesjs/blob/master/packages/bitbadgesjs-sdk/src/transactions/messages/base.ts#L117)

A transaction payload is the payload for a given transaction context and messages.
For Cosmos, the payload can be signed in Amino or Sign Direct format, so the payload.signDirect and
payload.legacyAmino are the payloads to sign.

If evmAddress is provided in TxContext, the payload will also include evmTx field with EVM transaction details.
