OSL User Guide: Comprehensive Guide to Private Wallet Whitelist Verification and Deposits

Embarking on your digital asset journey with OSL begins with a critical first step: completing the whitelist verification for your private wallet.

Why is Verification Required?

In adherence to the Anti-Money Laundering (AML) regulatory requirements set forth by the Hong Kong Securities and Futures Commission (SFC), compliance platforms must ensure absolute clarity regarding the source of funds. In short, users must demonstrate to OSL that the wallet in use is genuinely owned by them. Once verified, your asset transfers will be fully protected under our licensed operational framework.

Core Principles Before Depositing and Withdrawing (Must Read)

Before initiating any operations, please strictly adhere to the following principles:

• No Direct Exchange Transfers: It is strictly prohibited to withdraw digital assets directly from third-party exchanges (such as Binance or OKX) to OSL. Users must first withdraw assets to a personally owned private wallet (e.g., MetaMask) before transferring them into their OSL account.

• No Verification, No Deposit: Whether executing a deposit or a withdrawal, 'Whitelist Verification' must be completed first.

• Ensure Network Compatibility: Please verify that the network supported by OSL matches the blockchain network selected in your wallet perfectly (e.g., Ethereum ERC-20 protocol). Failure to do so may result in permanent asset loss.

Phase 1: Preparation (Consolidating Assets from Third-Party Platforms)

If your assets are currently held on other exchanges, please withdraw them to your private wallet first (using MetaMask as an example):

1. Copy the Address: Open MetaMask, confirm the selected network (e.g., Ethereum Mainnet), and click the address under 'Account' to copy it.

2. Withdraw from the Platform: Paste this address into the withdrawal page of the third-party exchange and select the corresponding blockchain network.

3. Reserve Gas Fees: On-chain transfers require network gas fees. Ensure that your private wallet holds a small amount of native tokens (e.g., ETH or SOL) to cover the network transaction fees for the subsequent transfer to OSL.

Phase 2: Core Operation - Private Wallet Whitelist Verification

OSL offers two verification methods. Users can choose flexibly based on the specific cryptocurrency:

Method 1: Wallet Connect Automated Signature (Most Efficient, No Transfer Required)

• Supported Assets: ETH, SOL, and their ecosystem tokens.

• Prerequisites: The OSL App and MetaMask must be installed on the same mobile device.

• Step 1: Access | Log into the OSL App -> [Assets] -> [Deposit] -> Select ETH or SOL.

• Step 2: Connect | Click [Add New Address] -> Select [WalletConnect Verification].

• Step 3: Authorize | The system will automatically redirect to your MetaMask application. Click [Connect] in the wallet pop-up window and wait approximately 2 seconds for the signature request to appear.

• Step 4: Naming and 2FA | Upon successful verification, return to the OSL interface, assign a name to the wallet (e.g., 'Personal Wallet 01'), and enter your Google Authenticator code (2FA).

• Step 5: Completion | Click [Sign] again to confirm. Once the page displays 'Address Verification Successful,' you may proceed to deposit immediately.

Method 2: Micro-Payment Verification (Universal Method)

• Supported Assets: BTC and other asset classes that do not support automated signatures.

• Step 1: Application | On the OSL [Assets] page, click [Wallet Verification] and select the corresponding cryptocurrency (e.g., BTC).

• Step 2: Registration | Enter your private wallet address, assign it a name, and complete the 2FA security verification.

• Step 3: Obtain Specific Amount | The OSL system will generate a specific random amount (e.g., 0.00012345 BTC) and an exclusive receiving address for you.

• Step 4: Manual Transfer | Open your private wallet and transfer the exact specified amount to this exclusive address.

• Step 5: Automatic Activation | Once the on-chain confirmation is complete, the system will automatically recognize this specific amount and officially whitelist the address.

Phase 3: Official Deposit (Funding)

After completing the whitelist verification, subsequent deposit operations require only three steps:

1. Obtain Address: Open the OSL App -> [Assets] -> [Deposit] -> Select the corresponding cryptocurrency -> Choose the verified whitelist address from the drop-down menu.

2. Initiate Transfer: Copy the receiving address provided by the OSL platform, paste it into your private wallet, and send the digital assets.

3. Receive Assets: Typically, within 5-15 minutes (depending on blockchain network congestion), the assets will be securely transferred to your OSL [Funding Account].

Expert Recommendations

• Optimize Experience: We highly recommend using Wallet Connect for verification. This method incurs no on-chain gas fees and can be completed in seconds.

• Operation Tracking: If you have any questions during the process, all transaction and verification records can be tracked and verified in real-time via the 'Billing History' in the top right corner of the [Assets] page.
