We are thrilled to announce our integration of Polyhedra Network. This guide is designed to help you navigate and make the most of this new integration to use zkBridge on Trust Wallet.
What is zkBridge
Polyhedra Network designs and implements zkBridge, providing trustless and efficient cross-chain infrastructures for layer-1 and layer-2 interoperability. zkBridge uses zero-knowledge proof constructions to efficiently convince the receiver chain that a certain state transition happened on the sender chain. With zero-knowledge proofs, zkBridge offers both strong security without relying on external assumptions and a significant reduction in on-chain verification cost.
Polyhedra network launched zkBridge Mainnet Alpha (https://zkbridge.com/) on April 2023, supporting token/NFT transfer and message passing across more than 20 layer-1 and layer-2 blockchain networks such as BNB Chain, Ethereum and Arbitrum. zkBridge is the first trustless, efficient, secure and universal cross-chaininteroperability protocol secured by zkSNARKs. The team invented and implemented deVirgo, a novel distributed proof system to accelerate the proof generation, and recursive proofs to reduce the on-chain proof verification cost of zkBridge.
