How to Restore a Keypair or Signer

If you have an existing secret key, you can restore your Keypair from it. This allows you to access your wallet and sign transactions in your dApp.

Handle secret keys with care: never embed them in client-side code or commit them to source control. For backend services in production, use a key-management backend instead of a raw secret key — see Signing in Production.

From Bytes

const keypairBytes = new Uint8Array([
  174, 47, 154, 16, 202, 193, 206, 113, 199, 190, 53, 133, 169, 175, 31, 56,
