Chainmanager module

This document specifies an overview of the chain manager module of Heimdall.

Overview

The chainmanager module is responsible for fetching the PoS protocol parameters. These params include addresses of contracts deployed on mainchain (Ethereum) and bor chain (Bor), chain ids, mainchain and bor chain confirmation blocks.

message ChainParams {
  option (gogoproto.equal) = true;
  string bor_chain_id = 1 [ (amino.dont_omitempty) = true ];
  string heimdall_chain_id = 2 [ (amino.dont_omitempty) = true ];
  string pol_token_address = 3 [ (amino.dont_omitempty) = true ];
  string staking_manager_address = 4 [ (amino.dont_omitempty) = true ];
  string slash_manager_address = 5 [ (amino.dont_omitempty) = true ];

  string state_sender_address = 8 [ (amino.dont_omitempty) = true ];
  string state_receiver_address = 9 [ (amino.dont_omitempty) = true ];
  string validator_set_address = 10 [ (amino.dont_omitempty) = true ];
}
