Simple to use, clear about how it works.
- Account wallet managed for you. Sanctum creates and secures the wallet that holds your USDC, so you do not handle keys or a seed phrase. Wallet keys are stored encrypted.
- One-time email codes. Every sign-in needs a fresh code sent to your inbox.
- Card details stay with the payment partner. Sanctum never sees or stores your card number.
- Transfers are on-chain. Every send is a public USDC transfer on Base that you can look up on a block explorer.
Know before you send
Blockchain transfers cannot be reversed. Double-check the address and make sure it is on Base before you confirm a send.
Questions, answered.
Do I need ETH to send USDC?
No. Sends on Base are submitted for you and the network fee is covered, so you only need USDC in your balance.
Who holds the wallet?
Sanctum creates and secures the wallet behind your account. You sign in with your email instead of managing keys or a seed phrase. If you want full control of keys, send your USDC to a wallet you manage yourself.
How do I buy USDC?
Choose an amount, pay with a card, Apple Pay or Google Pay, and the USDC is credited to your balance once the payment is confirmed. The checkout is run by our payment partner.
Which assets and networks are supported?
Currently USDC on Base.
What does it cost?
The amount you receive and any fees are shown before you pay and before you send, so you can review them first.
What if I lose access to my email?
Your account is tied to your email address. Keep access to that inbox, and move larger balances to a wallet you control.
Can I reverse a transfer?
No. Blockchain transfers are final, so check the address before you send.
Open Sanctum and get your USDC moving.
