# Wallets

> Blockchain wallet addresses assigned to your account for receiving or sending USDC and USDT via Fireblocks.

A wallet in Pythas is a blockchain address assigned to your account for receiving or sending USDC and USDT. All wallets are managed through Fireblocks custodial infrastructure.

<Info>
  Pythas does not create wallets on the client's behalf. A client-dedicated operational wallet is provisioned via Fireblocks upon account activation. The client does not hold private keys.

## Wallet whitelisting

If you want to send stablecoins from your own external wallet to Pythas for an off-ramp transaction, that address must be whitelisted before use. Submit the wallet address during onboarding via the MetaMap form field.

Modifications to a whitelisted wallet require a formal request and compliance review. Pythas reserves the right to remove a wallet from the whitelist if compliance concerns arise.
