[Administrator only] System environment pre-setup

Before starting the TSS service in the signing mode, there are several steps that need to be done after the key generation process completed.

Steps​

1. Fill the Bridge Core module settings​

The Bridge Core module settings, parameters, and data should be set up. This includes:

  • parameters:
    • tss_threshold - the threshold value for the TSS network;
    • parties - list of parties (Bridgeless Core adresses) that are running the TSS service;
  • state:
    • chains - list of chains that are supported by the TSS network;
    • tokens - list of tokens that are supported by the TSS network;
info

Samples of the CLI commands to update the Bridge Core module settings can be found here.

To obtain addresses of the TSS service for each chain, there is a list of CLI commands that can be executed:

  • Retrieving the TSS public key points:
tss-svc helpers vault get pubkey
  • Parsing the Ethereum address from the public key points:
tss-svc helpers parse address-eth <x-cord> <y-cord>
  • Parsing the Bitcoin address (P2PKH) rom the public key points:
tss-svc helpers parse address-btc <x-cord> <y-cord> --network testnet|mainnet

2. Fill the EVM contracts​

The TSS service address should be set in the EVM contracts as the signer address.

Use the following function to add the TSS service address to the signers list:

function addSigners(address[] calldata signers_) public onlyOwner;

3. Configure ZANO tokens​

When the TSS service public key is generated, Zano tokens should be configured with the new owner_eth_pub_key field to be able to execute the ADO operations using the TSS service signatures.
