Events

CIP-30 does not define a standard event emitter for the wallet interface. Account and network changes are communicated differently than in Ethereum or Solana providers.

Account changes​

When the user switches accounts in the wallet, subsequent API calls may fail with an APIError where code is AccountChange (-4). When this occurs, the dApp should call cardano.brave.enable() again to reestablish the connection to the new account. The wallet should not ask for confirmation in this case, since the user initiated the account change.

try {
  const balance = await api.getBalance();
} catch (err) {
  if (err.code === -4) {
    // Account changed - re-enable to connect to new account
    const api = await window.cardano.brave.enable();
  }
}
