Keep your keys off your iPhone. Cryptograph keeps them on Apple Watch, where every transaction is reviewed and approved before it is signed.
Cryptograph is a self-custody wallet built around Apple Watch as the signing authority. Your iPhone can prepare and relay transactions, but it cannot sign them.
Review what a transaction will do directly on Apple Watch before you approve it. Cryptograph decodes smart contract actions, token approvals, destinations, amounts, and fees on your watch, then signs only after your approval.
A compromised iPhone can prepare a malicious request, expose public wallet information, or try to mislead you. It cannot produce a signature. Your encrypted mnemonic stays on Apple Watch, protected at rest using the Secure Enclave.
No account. No email. No analytics. No trackers. No customer profile. No Cryptograph customer database to expose.
Time Lock adds configurable delays before funds can move, plus location-aware spend limits processed on-device.
For recovery, your watch can generate encrypted Recovery Sheets to share with someone you trust. No Cryptograph account or cloud backup required.
Supports Bitcoin, Ethereum, Solana, Base, BNB Smart Chain, Arbitrum, Polygon, TRON, XRP Ledger, Zcash, and more.
