The Constitution

Six principles we never break

Hardware-Grade Security

Secure Enclave

iPhone Secure Enclave provides chip-level protection. Your private key never leaves the security chip. Hardware wallet grade security, no extra device needed.

Carry extra hardware everywhere → iPhone is enough

100% Open Source

Transparency

Every line of code is public and auditable. No hidden logic, no backdoors, no trust required. Verify, don't trust.

Closed-source wallets → Fully auditable

Zero Dependencies, iOS Native

vs MetaMask

Pure Swift. Only Apple native APIs. No third-party libraries, no React Native, no cross-platform shortcuts. Zero supply chain risk.

1000+ npm packages → Pure Swift only

Self-Custody with Escape Route

Self-Custody

Secure Enclave for daily use, EOA for escape. No custody, no cloud sync—your recovery path is your own hardware wallet, not a third-party service.

Cloud-based recovery → 100% self-custody

Battle-Tested Contracts

Safe Ecosystem

Built on Safe smart contracts, which have secured $100B+ in assets since 2018. We use the latest audited version (1.4.1).

Unproven custom contracts → $100B+ battle-tested

500+ Networks, Same Address

CREATE2
