Universal Provider emits two events through the EventEmitter API on Node.js.

  • The dapp:accountsChanged event is triggered when an account change is detected inside the network. Returns the changed account address address and current chain name CHAIN_NAME in the form CHAIN_NAME:address as the input argument from a callback function.
type CHAIN_NAME = 'celestia' | 'celo' | 'cosmos' | 'ethereum' | 'juno' | 'klaytn' | 'near' | 'neon' | 'solana';

window.dapp.on('dapp:accountsChanged', (currentAccount: string) => {
  console.log(currentAccount); // near:welldone.testnet
});

2. chainChanged​

  • The dapp:chainChanged event is triggered when a network change inside the chain is identified. Returns the network ID networkID and current chain name CHAIN_NAME in the form CHAIN_NAME:networkID as modified by the input argument on a callback function.
type CHAIN_NAME = 'celestia' | 'celo' | 'cosmos' | 'ethereum' | 'juno' | 'klaytn' | 'near' | 'neon' | 'solana';

window.dapp.on('dapp:chainChanged', (currentNetwork: string) => {
  console.log(currentNetwork); //celo:0xf370
});
