Problem Statement
It can be challenging to transfer NFTs across zk-EVM Layer-2 rollups due to different approaches and/or difference in interfaces. We have taken a step towards eliminating these barriers and removing friction by building a one-stop application for dispatching cross-rollup NFT operations.
Solution
Transacta leverages the cross-chain messaging capabilities and bridging solutions currently available to transfer tokens between different networks. It can be considered a bridge aggregator that also offers features specifically designed for NFTs. In addition to EVM states bridging (tokenIDs, balances), transacta synchronizes NFT metadata and makes it available forPolybaseclients.Transacta operates between the following chains:Goerli testnet - acting as a main network for the NFT assetScrolltestnet - EVM-compatible zero-knowledge rollupPolygonzkEVM testnet - L2 zero-knowledge sidechainzkSyncEra - Layer 2 zkEVMNFT metadata relayer mirrors initial metadata stored using HTTPs webservice to decentralizedPolybase db.
