Ethereum params

To add EVM-compatible networks to the WELLDONE wallet, send the following object as a factor to params.

Ethereum

interface ChainData {
  // Identifier to distinguish the chain
  chainId: string;
  // The name of the chain to be displayed to the user.
  chainName: string;
  // RPC endpoint of the chain.
  rpcUrls: Array<string>;
  iconUrls: Array<string>;
  nativeCurrency: {
    name: string;
    symbol: string;
    decimals: number;
  };
  blockExplorerUrls: Array<string>;
}

Example

The following is an example that the addition of an EVM-compatible Ubiq testnet. Click the Add Chain button. You must first connect to your wallet using the dapp:accounts method before using the dapp:addChain method.
