# verify: Wire format

> Wire format: 1 export of the verify module of @eco-incorp/sauce, including SETTLE_WIRE.

`@eco-incorp/sauce/verify` validates an EVM settlement payload against the pinned settle program (`SETTLE_WIRE`: compiler 2.3.0, 356 bytes) and decodes its runtime argument tail. It depends on viem only, so it runs in browsers and edge runtimes without loading the compiler.

This page covers `sdk/dist/verify/wire.d.ts`.

<Note>
  Generated from the type declarations shipped in `@eco-incorp/sauce` 0.99.4. Each entry shows the package authors' JSDoc and declaration for this SDK version. For runtime compatibility and deployed addresses, see [architecture and deployments](/programmable-transactions/sauce/architecture-and-deployments).
