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.

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 Canister

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.

Threshold 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 thresold signing protocols like EdDSA and BLS are coming soon.

HTTPS 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.
