Summary

  • add core::mcp_relay_submit module for relay attestation submission to slot leader
  • implement strict RelayAttestation v1 parser/serializer with sorted+unique proposer-entry validation
  • add relay-signing bytes helper and leader-side relay/proposer signature verification helpers
  • add MCP control-frame helpers with message-type prefix 0x01 for relay attestations
  • add dispatch helper that resolves Leader[s] and prepares a leader-targeted frame

Testing

  • cargo test -p solana-core --lib mcp_relay_submit -- --nocapture

Closes #13
