Harnessing Chain-Key Cryptography for Instant, Low-Cost Bitcoin Payments
Transferring Bitcoin natively on layer-1 involves slow block times (10 to 60 minutes) and volatile miner fees. Traditional wrapped Bitcoin solutions introduce centralized custody risks and multi-signature bridge vulnerabilities.
ICPay supports chain-key Bitcoin (ckBTC), providing true 1:1 Bitcoin value with sub-second finality.

Core Technical Architecture & Mechanisms
───────────────
1. True 1:1 Bitcoin Backing
ckBTC is fully backed by real Bitcoin held directly by the Internet Computer protocol canisters without third-party custodians.
2. Sub-Second Bitcoin Velocity
Transfers of ckBTC settle in under one second, transforming Bitcoin into a viable currency for everyday retail transactions.
3. Fixed Sub-Cent Fees
Transfers execute with deterministic low network fees, bypassing expensive Bitcoin base-layer mempool congestion.
