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 / OTP login.

Signing & gasless

Silent secp256r1 signing and paymaster-sponsored execution.

Multi-device

Add a new device to an existing wallet with on-chain approval.

Recovery

Passphrase-derived backup signer — non-custodial after device loss.

API reference

Every export in the package, with types and signatures.

No seed phrases

A non-extractable device key signs invisibly. The user never sees a private key.

MPC-free

No key sharding, no signing servers. The key is whole and on the device.

Verifiable on-chain

Signatures are checked by the account contract, not trusted from a backend.

Built for agents

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