7. Asset Deposit & Withdrawal for Passkey Users

Users who log in via third-party authorization can verify their identity with Passkey and create a 1DEX blockchain account, ensuring self-custody and asset security.

When Passkey users perform Deposit or Withdrawal operations, 1DEX enables cross-chain transfers between the user's source chain assets and their 1DEX blockchain account via the exSat Bridge.

exSat Bridge is a secure cross-chain bridge under the custody of licensed custodians, Such as Ceffu, Cactus, and ChainUp. About exSat Bridge >

The process is as follows:

When depositing assets (such as BTC or USDT), the funds are directly transferred to the user’s 1DEX blockchain account via the exSat Bridge. For withdrawals, after Passkey verification, assets are transferred from the user’s 1DEX blockchain account to the target chain specified by the user through the exSat Bridge.

Throughout the entire bridging process, 1DEX has no access to user assets, ensuring the security of funds. This design leverages the high security of Passkey and the bridging capability of exSat Bridge to provide users with a secure and efficient asset management experience.
