WHY BIG

Protecting your keys is difficult.
We are making it easy for you.

Multisig for everyone

Every transaction requires approval from both browser and phone. Your self-custody just got two times more secure.

No seed phrases

Passkey-based onboarding gated by Face ID, Touch ID, or your security key. No copies that can be easily found by attackers.

Trustless recovery

Lost a device? Any two of three keys can swap in a new one — atomic, on-chain. No support tickets, no lost funds.

Don't trust, verify

Both extension and mobile app surface every relevant transaction detail — and flag dangerous instructions. No more blind signing.

100% open source

Every line — on-chain program, relay, extension, mobile app — is auditable. Built for professionals who need to verify, not take our word.

Built for speed

Zero-friction approvals at the pace of Solana. Everything in one transaction — done in seconds, not the minutes a classic multisig or MPC takes.
