# KYC and Payments

> Set up your payment information to receive rewards

## Know Your Customer

To receive payments you must first undergo the Know Your Customer process. This process is conducted using [withpersona.com](https://withpersona.com/). Cantina does not store any personal user information.

After the identity verification process is complete, you will be able to set up your address and receive payments.

## Add Payment Address

Follow the steps below to edit your payment settings and add your preferred **Ethereum mainnet address** to **receive USDC**.

<Warning>
  **Only Ethereum mainnet addresses are supported.** No other chain is currently supported.
</Warning>

If you are operating as a legal entity, it is possible to issue an invoice to Cantina for your own records. For when and how you'll receive payments (schedule, delays, troubleshooting), see [Payout Schedule & Process](/for-security-researchers/joining-cantina/payout-schedule).

<Note>
  All payments will be sent out through our [multisig](https://cantina.xyz/blog/a-guide-to-multi-sig-security-in-2025-from-simple-exploits-to-system-wide-compromises).
