🔥Introduction
Cross-chain Routing API, Omnichain Messaging & ZK Light-Client Infrastructure
Butter Network provides developer infrastructure for building secure, fully onchain cross-chain applications.
These docs explain how to integrate cross-chain swaps, omnichain messaging, and interoperability flows powered by Butter’s ZK light-client technology.
Butter is designed for developers building wallets, DEXs, dApps, and protocols that require trust-minimized cross-chain execution — without multisigs, external validators, or centralized relayers.
Getting started
If you are new to Butter Network, start with:
What you can build with Butter Network
Using Butter Network, developers can:
Enable one-step cross-chain swaps across Bitcoin, EVM chains, Solana, and TRON
Integrate cross-chain routing that combines bridging and onchain swapping into a single flow
Build omnichain applications with verified cross-chain execution
Access non-custodial liquidity routing sourced directly from onchain DEX and AMM pools
Leverage ZK light-client verification for secure, trust-minimized settlement
Butter’s architecture is optimized for composability, safety, and production-ready integrations.
