BTC <> ICP
ICP has protocol-level integration with the Bitcoin network, enabling dapps to seamlessly interact with Bitcoin and granting users access to the Bitcoin economy like never before with ckBTC.
By running Bitcoin adapters, ICP nodes provide canister smart contracts with real time access to the latest state of the Bitcoin blockchain. The availability of the Bitcoin UTXO set on ICP enables canister smart contracts to read the balance of any BTC address.
ICP nodes collaborate to produce threshold-ECDSA signatures, enabling canister smart contracts to sign BTC transactions. Leveraging network integration, these BTC transactions are directly inscribed on the Bitcoin blockchain - no need for any cross-chain bridges. Chain-key signatures also derive BTC addresses, enabling ICP smart contracts to read, write and own BTC.
Developers can harness the security of bitcoin as a native asset while also leveraging the unique core features of the ICP tech stack. These include the reverse gas model, unparalleled performance, and HTTPs outcalls, all within the framework of full-stack decentralization—a hallmark of the industry’s only third-generation blockchain.
Beyond Bitcoin adapters, ICP smart contracts can read and write to other blockchains providing an unrivaled interconnected Web3 experience. A single smart contract can read, write, and own assets on multiple blockchains via features such as network integration, RPC integration and HTTPs outcalls.
Native Bitcoin transactions entail paying high fees and enduring lengthy wait times for block confirmations. Enter ckBTC, a 1:1 bitcoin twin introduced to leverage the 1-2 second finality and negligible fees within the ICP ecosystem. ckBTC is one of the first Chain Fusion applications, and powers several dapps across different use-cases.
Chain-key bitcoin (ckBTC), a multi-chain bitcoin twin on the Internet Computer, is anICRC-1-compliant token that is backed 1:1 by bitcoin (BTC) such that 1 ckBTC can always be redeemed for 1 BTC and vice versa.
The total supply of ckBTC tokens, which is the amount of ckBTC tokens that have been minted minus the amount that have been burned.
The amount of ckBTC tokens transferred, minted, or burned, or for "approve" transactions, the designated amount of ckBTC tokens that the "Spender Account" is authorized to transfer on behalf of the "From" account.
The volume of ckBTC tokens transferred, minted, or burned. Date ranges of one month or longer show daily volume, while shorter date ranges show hourly volume. The total volume shown in the chart header is the total for the selected date range.
Bitcoin on ICP is not just a future promise. Developers are already building incredible use cases with Bitcoin on ICP.
Sell, trade, and transfer Bitcoin Ordinals and inscriptions without gas fees and transaction speed of less than two seconds.
