Chain-Key Bitcoin (ckBTC) Integration

What This Is

ckBTC is a 1:1 BTC-backed token native to the Internet Computer. No bridges, no wrapping, no third-party custodians. The ckBTC minter canister holds real BTC and mints/burns ckBTC tokens. Transfers settle in 1-2 seconds with a 10 satoshi fee (versus minutes and thousands of satoshis on Bitcoin L1).
