Requirements
As of 9/15/2025, to use this service you must:
- Use the Chrome Browser
- Install the MetaMask extension
- We use an Ethereum address to sign in and encrypt data
- We don't use it to transfer or receive funds.
- So you can use a new address, but keep it around because those are your account credentials.
- Have a Circle Mint account and API key
Mainnet vs Sepolia
For now you can only send funds using the Sepolia test network.
- Internally, we use the Mainnet to send funds, so if you are interested in having us turn that on for you, please contact us.
We are slowly relaxing these requirements as our banking integration matures.
