Super Bitcoin (SBTC) is set to undergo a hard fork at block height 498888—anticipated around December 13, 2025, Beijing time. As a leading platform committed to advancing Bitcoin and digital asset innovation, OKX supports all major technological developments within the Bitcoin ecosystem. We do not dictate which version of Bitcoin users should adopt; instead, we empower the market and our users to make informed decisions.
To ensure a seamless experience during this critical network event, OKX has implemented a comprehensive plan for SBTC trading, conversion, and distribution. Below is a detailed breakdown of our approach, designed to protect user assets, maintain platform stability, and provide maximum flexibility.
🔧 Key Features of SBTC Support on OKX
1. Early Access to SBTC Conversion and Trading
Starting December 7, 2025, at 18:00 (UTC+8), OKX will enable BTC-to-SBTC conversion ahead of the fork. This allows users to prepare for potential outcomes without waiting for the actual fork event.

2. Transparent Asset Management: SBTC and F4SBTC
To clearly distinguish between original BTC and pre-fork exposure, OKX introduces two distinct asset labels:
- SBTC: The new token issued by the Super Bitcoin hard fork.
- F4SBTC: A temporary placeholder representing BTC locked in anticipation of the fork.
When you convert 1 BTC, you receive 1 SBTC + 1 F4SBTC. These assets can be freely exchanged back to BTC before the fork occurs.
⚠️ Important: F4SBTC is non-transferable and cannot be traded or withdrawn until the fork resolves. This ensures system integrity and prevents double-spending risks.
📅 Timeline and Operational Rules
Pre-Fork Phase (Until Block Height 498888)
During this period:
- Users may freely convert BTC ↔ (SBTC + F4SBTC) at a 1:1 ratio.
- SBTC/BTC trading pairs will go live, allowing speculative positioning.
- All conversions are reversible—users retain full control over their choices.
Post-Fork Scenarios
✅ Case 1: Fork Succeeds
If the SBTC chain stabilizes after block 498888:
- All users holding BTC in their spot accounts will receive an equal amount of SBTC (1:1 airdrop).
- F4SBTC will automatically convert back to BTC at a 1:1 rate.
- Contract and C2C account holders will also receive SBTC based on snapshot balances (details below).
❌ Case 2: Fork Fails
If the SBTC network does not gain traction or fails to stabilize:
- Users can revert their F4SBTC holdings back to BTC at par value.
- No SBTC distribution will occur.
- The platform will resume normal BTC operations seamlessly.
🔄 Case 3: Alternative Stable Fork Emerges
Should another Bitcoin fork gain stability at or near the same block height:
- OKX will distribute additional "fork candy" tokens proportional to the user’s combined BTC and F4SBTC balance.
- This ensures fair compensation regardless of which chain prevails.
🧾 Account-Specific Snapshot Policies
Different account types are treated according to their risk profiles and usage patterns:
Spot Accounts
At block height 498888:
- A snapshot of all available BTC balances will be taken.
- Eligible users will receive 1 SBTC per 1 BTC held.
Contract Accounts
For derivatives traders:
The system will calculate total account equity, including:
- Margin balance
- Realized P&L
- Unrealized P&L
- SBTC allocation will reflect this BTC-denominated equity value.
C2C Accounts
Peer-to-peer traders:
- Only available BTC balance at snapshot time counts toward SBTC eligibility.
- Locked or escrowed funds are excluded.
⚖️ Market Implications and Risk Management
Due to BTC serving as the primary pricing base asset on OKX, the fork introduces short-term volatility risks:
- Before the fork: Trading pairs like ETH/BTC, LTC/BTC, and ETC/BTC represent value against combined BTC chains (F4SBTC + SBTC).
- After successful fork: These pairs instantly shift to being priced solely against post-fork BTC (i.e., F4SBTC), causing potential price jumps.

We strongly advise users to:
- Monitor price movements closely.
- Adjust open orders and positions accordingly.
- Consider using stop-loss and take-profit mechanisms.
🔐 Security and Service Updates
To maintain network-level accuracy and prevent fraudulent deposits:
- BTC deposits and withdrawals will be temporarily suspended from just before the fork until network stability is confirmed.
- We recommend depositing BTC in advance to avoid missing trading opportunities.
- Our technical team will monitor both chains continuously to ensure accurate balance allocation and timely resumption of services.
All users will retain full access to their assets across both chains, should both remain viable.
