Multichain, device-native
embedded wallets.

Build self-custodial embedded wallets across blockchains with one chain-configurable SDK — an OpenZeppelin account on Starknet, native Ed25519 accounts on Solana and Stellar. Every chain that comes next joins through an adapter.

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

const cavos = await Cavos.connect({
  chain: "solana",
  network: "testnet",
  identity: { userId, email },
  appSalt: "my-app",

if (cavos.chain === "solana") {
  // The relayer is fee payer; the account holds the lamports.
  await cavos.execute(amount, recipient);

Start building

Guides and reference for integrating @cavos/kit.

Quickstart

Install @cavos/kit and ship a gasless transaction in five lines.

Authentication

Bring your own identity, or use hosted Google / Apple / email code login.

Signing & gasless

Silent signing and paymaster-sponsored execution.

Multi-device

Open an existing wallet on a new device by restoring its MasterDEK.

Recovery

Passkey or enclave sign-in. Non-custodial after device loss.

API reference

Every export in the package, with types and signatures.

Reserve

Pay Stellar reserves and fees in a token, from any G… wallet.

No seed phrases

Authority is created or unlocked locally through the selected chain adapter. The user never manages a seed phrase.

MPC-free

No reconstructable server-side key shards and no Cavos signer that can move user funds.

Chain-native

Each adapter uses the network’s real account, signature, execution, and fee model.

Built for agents

Every page is available as plain text. Pipe the whole site into an LLM and let it write your integration.
