Embedded wallet SDK for Starknet, Solana, and Stellar. Hardware-isolated, non-custodial.

cavos.xyz/embedded-wallet · Docs · Pricing

• Users sign in with Google, Apple, GitHub, Telegram, or an email code. No seed phrase and no browser extension.
• Signing always happens on the user's device. The hardware-isolated enclave and the passkey only keep an encrypted copy of the master key, used to restore on a new device.
• Each chain uses its native account: the audited OpenZeppelin account contract on Starknet, a native Ed25519 system account on Solana, and a classic G account on Stellar.
• Gas Sponsorship in Any Token, so users can transact without holding the chain's native coin.
• Connect never deploys. The first execute deploys the account and runs your calls atomically.

@cavos/kit includes @cavos/kit/react and @cavos/kit/react-native.

import { Cavos } from "@cavos/kit";

  identity: { userId: "user-123", email: "user@example.com" },
  appId: "your-app-id",
});

if (wallet.status === "undeployed" || wallet.status === "ready") {
  await wallet.execute(1_000_000n, recipient);
}
