Builder API types & signing

Goreport status Test status

Tested types and signing routines of the Eth2 Builder API.

This is useful for:

  • validators and beacon nodes can use it to communicate with mev-boost, relays and builders after the merge
  • mev-boost, which uses the types in this repository to comminicate with relays and builders
  • for future builders, to communicate with relays
  • to build testing, monitoring and verification utilities

See also:


  • types/common.go: various common basic datatypes (Signature, PublicKey, Hash, etc), with tested SSZ encoding
  • types/builder.go: builder-API specific datatypes, with tested SSZ encoding
