feat: add ptc state endpoint by nflaig · Pull Request #10190 · ChainSafe/lodestar

nflaig · 2026-09-26T14:38:05Z

Motivation

Implement ethereum/beacon-APIs#657 and SSZ support from ethereum/beacon-APIs#661 so consumers can retrieve the PTC for a slot without fetching the full state.

Description

add the endpoint to the API client and beacon node with JSON and SSZ responses
preserve committee order and duplicates, default to the state's slot and validate the fork and PTC window
cover the endpoint with client/server tests and focused handler tests
