# Account activation

> Activating an account for enabling transactions.

Before an end user can make deposit/withdrawal transactions, their account must be activated. The activation allows the account to benefit from the following features:

* Gas sponsorship for transactions: no need to pay for gas fees
* Be whitelisted to deposit into all Byzantine Prime vaults

<Info>
  At the moment, there are two authentications to complete so the account can
  deposit into both Byzantine Prime USDC and Byzantine Prime EUR vaults. This
  step will be automated in the future.

## Steps to proceed

1. You call the passkey activation payload endpoint to retrieve an authorization body to sign.

2. The end user signs this payload with their passkey.
3. You submit the signed payload so Byzantine can sponsor and broadcast the activation transaction.
