Chain management

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

The chain manager module provides all necessary dependencies like contract-addresses, bor_chain_id, and tx_confirmation_time. Other parameters can be added to this later on.

Params are updated through the gov module.

Types

Chainmanager structure on Heimdall looks like the following:

type ChainParams struct {
 // BorChainID is valid bor chainId
 BorChainID            string                  `json:"bor_chain_id" yaml:"bor_chain_id"`

 // MaticTokenAddress is valid matic token address
 MaticTokenAddress     hmTypes.HeimdallAddress `json:"matic_token_address" yaml:"matic_token_address"`

 // StakingManagerAddress is valid contract address
 StakingManagerAddress hmTypes.HeimdallAddress `json:"staking_manager_address" yaml:"staking_manager_address"`

 // RootChainAddress is valid contract address
 RootChainAddress      hmTypes.HeimdallAddress `json:"root_chain_address" yaml:"root_chain_address"`

 // StakingInfoAddress is valid contract address
 StakingInfoAddress    hmTypes.HeimdallAddress `json:"staking_info_address" yaml:"staking_info_address"`

 // StateSendedAddress is valid contract address
 StateSenderAddress    hmTypes.HeimdallAddress `json:"state_sender_address" yaml:"state_sender_address"`

 // Bor Chain Contracts
 // StateReceiveAddress is valid contract address
 StateReceiverAddress hmTypes.HeimdallAddress `json:"state_receiver_address" yaml:"state_receiver_address"`

 // ValidatorSetAddress is valid contract address
 ValidatorSetAddress  hmTypes.HeimdallAddress `json:"validator_set_address" yaml:"validator_set_address"`
}
