ProofBridge is a decentralized cross-chain bridge that lets you transfer assets between blockchain networks without trusting any third party. Instead of routing funds through a centralized custodian or validator committee, ProofBridge uses zero-knowledge proofs and direct peer-to-peer matching between liquidity providers (Makers) and bridge users (Bridgers).Documentation Index

How ProofBridge works
ProofBridge matches Bridgers (users who want to transfer assets) with Makers (liquidity providers) through a marketplace of liquidity advertisements. Settlement is secured by zero-knowledge proofs — neither party needs to trust the other or any intermediary.Maker posts liquidity
A Maker creates a liquidity ad on their source chain, locking tokens they want to provide for cross-chain transfers.
Bridger deposits funds
A Bridger selects an ad and deposits the source-chain token on the OrderPortal contract. This creates a cryptographically signed order.
ZK proof is generated
The relayer generates a zero-knowledge proof attesting that the deposit exists in the source chain’s on-chain Merkle tree — a succinct cross-chain attestation that the destination chain can verify directly.
ProofBridge is currently live on Ethereum Sepolia and Stellar Testnet. Mainnet deployments are on the roadmap.
