Keys never leave your device

Your keys are nobody's business.

Quad7 is a self-custody wallet for USDC: you sign every payment and it goes straight to whoever you choose — we never hold your funds.

How a payment moves

Your wallet → their wallet. Nobody in between.

USDC on Base
1. Review

Paste an address or open a payment link. See the amount, network and receiving address before anything happens.

2. Sign

Unlock with your PIN or Face ID and sign on your own device.

3. Done

USDC moves straight from your wallet to theirs. We never touch the money or see who you paid.

The part everyone worries about

Custody stops being scary when it's legible.

Most wallets throw hex strings at you and hope for the best. Quad7 names every address you've used, previews every fee before you sign, and tells you in plain words what a transaction will do.

“I'll lose my seed phrase”

Your recovery phrase is generated on your device and shown once for you to write down. It is never sent to us.

On-device key generation

“I won't know what I'm signing”

Every signature request is translated into a sentence: what leaves, what arrives, what it costs.

Human-readable signing

“What if I mistype the address?”

Every payment shows the full receiving address and amount for you to check before you sign. Payments are final.

Clear review before signing

“Which network do I use?”

Pay with USDC on Base or Ethereum. Your live balance on each is read straight from the blockchain.
