Hello, Bitcoin
BUILD on Bitcoin at the speed of ICP. Bitcoin on ICP is not just a future promise, developers are already building incredible use cases.
Bitcoin integration
enables smart contracts to interact with multiple networks allowing developers to realise multichain use cases and profit from ICP features.
See supported chains
Benefits
Seamless and secure interoperability between different blockchains unlocks new possibilities.
Smart contracts can hold BTC, ETH, and other tokens
ICP Smart contracts can read, write, own, and program multiple tokens across different networks, abstracting complexity away from the user and breaking the silos introduced by scaling solutions.
Unique ICP features
If you have a dapp, you can profit from ICP features without migrating your smart contract or dapp to ICP. Chain Fusion enables web2 interaction, timers, reactions to Ethereum or Bitcoin events, and more.
On-chain orchestration
Seamless cross-chain communication and orchestration. An ICP smart contract can orchestrate your Ethereum dapp's payments to the Bitcoin network, or execute DAO votes autonomously across chains.
ICP as a Coprocessor
Your dapp or smart contract can now offload heavy or expensive compute tasks to ICP without having to migrate your dapp or use an insecure solution.
igniting a thriving ICP Ecosystem
Chain Fusion is empowering projects to innovate and succeed. By providing advanced features and seamless integration, it enables groundbreaking solutions.
Discover the Chain Fusion Ecosystem
ckTokens
Chain-key twin tokens like ckBTC, ckETH allow users to leverage the ICP network for fast, low cost, and user-friendly transfers.
Metaprotocols
Metaprotocols leverage Chain Fusion to offer decentralized cross-chain infrastructure enabling the transfer and creation of new assets on Bitcoin.
Crosschain DEXes
Decentralized Exchanges use Chain Fusion to facilitate trading of assets from different blockchains, providing a uniform user experience.
Marketplaces
There are marketplaces for Ordinals and Runes that use Chain Fusion to allow users to purchase or trade efficiently, quickly, and easily.
building blocks for developers
ICP's native Bitcoin integration and RPC integrations, coupled with a suite of threshold signing protocols open a world of possibilities for developers.
Bitcoin UTXO API
Developers can create smart contracts that interact directly with the Bitcoin mainnet and testnet networks through ICP's direct integration with Bitcoin. The Bitcoin UTXO API allows to query and return information from the Bitcoin network, e.g. UTXOs and balances or the percentiles of the fees for the last 10'000 transactions.

EVM RPC is a smart contract that communicates with Ethereum and other EVM blockchains using an on-chain API. Communication includes obtaining and sending information such as the logs of a specific block or transaction, historical data regarding the network's gas fee, transactions for a specific address, or submitting a signed transaction.
Read moreThreshold Signing Services
ICP has a suite of threshold signing protocols including ECDSA and Schnorr which allow to sign a variety of transactions across chains like Ethereum and Bitcoin. Further threshold signing protocols like EdDSA and BLS are coming soon.
Read moreHTTPS Outcalls
HTTPS outcalls can be used to directly obtain off-chain data or interact with off-chain systems, such as Web 2.0 services or enterprise IT infrastructure. For example, oracle services can directly integrate with ICP in a trustless manner, dapps can provide user notifications, or communicate with other chains via RPC endpoints.

Full support for Ethereum and other EVM chains is now live allowing ICP smart contracts to augment EVM-based smart contracts with additional functionality.

Bitcoin Runes Arrive at the Halving—And Internet Computer Will Support Them
Apr 16, 2024 by Jason Nelson
With the Bitcoin halving and Runes protocol launch taking place this weekend, Dfinity is continuing Internet Computer's embrace of the Bitcoin ecosystem by adding support for etching Runes tokens and other BTC-centric functionality, the company said on Tuesday.
ckBTC: A Decentralized Mechanism for Efficient Bitcoin Transfers
Apr 18, 2024 by Dfinity
On September 7, 2021, Bitcoin obtained the status of legal tender within El Salvador. Shortly after the adoption of the so-called ‘Bitcoin law’, many Salvadorans had already opened Bitcoin wallets. However, as per a recent study done by the José Simeón Cañas Central American University, in 2023 just 12% of the local population engaged in cryptocurrency transactions in 2023.
