* **Web2 users (On-chain transactions through a custodial wallet)**
  * Users initiate transactions and ensure their wallet has sufficient assets and gas fees.
  * The custodial wallet deducts the corresponding assets and signs the transaction.
  * The custodial wallet completes the on-chain transaction via OKX OS.
  * Upon transaction completion, the corresponding assets are credited to the user's account.
* **Web3 users (Users independently complete on-chain transactions via external wallets)**
  * Users initiate transactions and ensure their wallet has sufficient assets and gas fees.
  * Confirm the transaction within their external wallet.
  * The front-end calls OKX OS to complete the on-chain transaction.
