Brave Wallet detection

CIP-30 wallet namespace​

Per CIP-30, each wallet implementing the standard creates a namespaced field under the shared window.cardano object. Brave Wallet uses the namespace brave, so the wallet object is available at window.cardano.brave.

Synchronous detection​

const isBraveWallet = window.cardano?.brave != null
console.log('Brave Wallet (Cardano): ', isBraveWallet)

Checking before enable​

Before calling enable(), you can check wallet availability and optionally use isEnabled() to see if the dApp is already connected:

if (window.cardano?.brave) {
  const alreadyConnected = await window.cardano.brave.isEnabled()
  if (alreadyConnected) {
    const api = await window.cardano.brave.enable()
    // Use api...
  }
}
