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

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.
