Welcome to OSL. Whether you're entering the digital asset space for the first time or migrating from another platform, funding your account is the first step to start trading.
As a digital asset trading platform licensed and regulated by Hong Kong's SFC, OSL supports secure deposits in multiple major fiat currencies (HKD, USD, EUR, GBP) — no need for P2P, OTC, or other high-risk channels. Fund directly from your bank account and buy Bitcoin as safely as buying stocks.
This guide breaks down every deposit method to help you choose the best channel. If you don't have an OSL account yet, we recommend completing your account registration and KYC verification first.
Before initiating a transfer, ensure you've completed these two prerequisites to maximize your deposit success rate:
Your OSL account must have passed identity verification. Not done yet? See our Account Opening & KYC Complete Guide — the entire process takes approximately 5 minutes.
If you'd also like to set up two-factor authentication for enhanced account security, refer to the OSL Account Opening & 2FA Setup Guide.
To comply with Anti-Money Laundering (AML) regulations, OSL only accepts transfers from bank accounts that exactly match your registered name.
Never use:
Joint accounts
Corporate accounts (unless you are an institutional client)
Accounts belonging to spouses, parents, or friends
For Hong Kong local users, we offer three convenient HKD deposit channels:
Method | Speed | Fees | Best For |
|---|---|---|---|
FPS (Faster Payment System) | 🚀 Instant – Minutes | Free | Top recommendation.
Ideal for users who need to act fast on market movements |
eDDA (Electronic Direct Debit) | 🚀 Instant | Free | Ideal for large deposits or DCA investors. One-time authorization, then debit directly within OSL |
Local Bank Transfer | ⏳ Same day or next business day | Bank-dependent | Suitable for users who prefer traditional transfers |
Log into the OSL platform, navigate to[Home]or[Assets], and tap[Deposit]
Select fiat currency [HKD]
Choose your deposit method (FPS or eDDA recommended)
Get payment details: The system will display OSL's dedicated receiving account or FPS Proxy ID
Execute transfer: Open your banking app and enter the amount and payment details as shown
💡 Key Tip: If using traditional bank transfer, always include your [Transaction Reference Code] in the remarks/memo field. This enables automatic identification and faster crediting.
To deposit USD, EUR, or GBP, the primary method is Bank Wire Transfer (SWIFT).
On the[Home/Assets]page, tap[Deposit]and select your desired currency (e.g., USD)
The system will generate OSL's overseas bank receiving details (including SWIFT Code, bank name, account number, etc.)

Processing Time: International wire transfers typically take 1–3 business days (depending on the sending bank and intermediary banks).
