# Interface: BuildEIP712Args

Defined in: [packages/bitbadgesjs-sdk/src/eip712/build.ts:18](https://github.com/BitBadges/bitbadgesjs/blob/master/packages/bitbadgesjs-sdk/src/eip712/build.ts#L18)

High-level helper that mirrors the inputs `createTransactionWithMultipleMessages`
takes and returns the EIP-712 typed-data ready for an EVM wallet.

Same Amino encoding pipeline that powers `legacyAmino.signBytes` — so any
Msg type with an Amino converter registered works automatically. Adding
a new Msg type to the Amino registry adds it to this builder for free.
