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. This allows developers to build multichain use cases on various blockchains.
GM Ethereum
Full support for Ethereum and other EVM chains is now live allowing ICP smart contracts to augment EVM-based smart contracts with additional functionality.
Ethereum Integration
Benefits
Seamless and secure interoperability between different blockchains unlocks new possibilities.
Unique ICP features
You can utilize ICP’s core tech stack without migrating your smart contract or dapp to ICP. Chain Fusion technology enhances other Web3 ecosystems through unique features like chain-key signing, compute on-chain, and HTTPs outcalls, enabling builders to augment their crypto dapps.
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.
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.

ckTokens
Chain-key tokens, like ckBTC, ckETH and ckUSDC, are 1:1 twin tokens backed tokens that enable fast, low-cost, and seamless transfers without third-party intermediaries.
Metaprotocols
Metaprotocols leverage Chain Fusion to offer decentralized cross-chain infrastructure enabling the transfer of new assets on blockchains.
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 reading from and writing to the Bitcoin network, e.g. UTXOs and balances or the percentiles of the fees for the last 10'000 transactions.

This smart contract enables decentralized RPC integrations with Ethereum and other EVM blockchains. 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 incorporates a suite of threshold signing protocols including ECDSA and Schnorr which allow signing a variety of transactions across chains such as 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.

Chain Fusion Technology: The Key to a Multichain Ecosystem
July 31, 2024 by Medium
As a developer, how often do you find yourself struggling to integrate multiple blockchain networks for a single decentralized application? Perhaps you’re managing assets on Ethereum, serving frontends from IPFS, and handling smart contract computations on Arbitrum or Optimism. Each network demands you to adapt to different programming models, transaction costs, and settlement times. The process is cumbersome, inefficient, and complex.

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.
