OBTC is Bitcoin-derived and uses historical Bitcoin UTXO state as part of the candidate model. That does not make this page an instruction to claim, move BTC, expose keys, or treat any future claim path as financial advice.
Current candidate values
- Fork height:
1000000, provisional - Replay-protection activation height:

h_create <= 639136
Final claim guidance requires final release artifacts, replay-protection review, wallet readiness, and public safety instructions.
FAQ
Do I automatically have OBTC if I held BTC at the fork height?
OBTC is designed as a Bitcoin-derived system, so historical Bitcoin UTXO state is part of the candidate model. The exact user-facing claim process is not final public guidance yet and depends on final release artifacts, replay-protection review, wallet readiness, and safety documentation.
Do I need to move my BTC?
No public instruction exists yet. Do not make a claim flow before final safety docs are published, and do not expose private keys to experimental tooling.
What does replay protection protect?
Replay protection is intended to reduce cross-chain signature confusion. In plain language, it helps separate OBTC transactions from Bitcoin transactions so one chain's transaction data is not accidentally accepted as the other chain's action.
Is mainnet-candidate production?
No. Mainnet-candidate does not mean production-ready financial infrastructure.
