Developers launch a bridge between Polygon and zkEVM

Polygon Labs has launched a cross-chain bridge that connects the Polygon and zkEVM blockchains. It is based on zero-knowledge proofs.

According to the developers, the Polygon Bridge for zkEVM offers almost the same user interface as its Polygon PoS counterpart.

The team has introduced a number of improvements, including changes to the progress indicator, the colour-coded status on the latest transactions panel, estimated times for unfinished operations, and the ability to filter.

Users can expect rapid finalisation. Transferring funds to Ethereum may take 30–60 minutes, unless the network is experiencing abnormal conditions, the team noted.

The cross-chain bridge supports most popular assets, including ERC-20 and ERC-777 tokens.

After initiating a transaction through Polygon Bridge, the bridged token will be automatically mapped. In other solutions, this process involves a similar manual step before the transfer itself, potentially taking hours or even days.

Teams from Lens, Balancer, ANKR, Alchemy, Sequence, The Graph, as well as Midnight Society and Oath of Peak are already working on integrating the cross-chain bridge.

Earlier, the startup Recursive launched the Omni Network infrastructure for interacting with Ethereum-layer second-layer networks such as Optimism, Arbitrum, zkSync Era or StarkNet built on ZK-Rollups.

Recently, developers of the omni-chain protocol LayerZero announced integration with Polygon zkEVM.

In March, Ethereum co-founder Vitalik Buterin called the integration of zkEVM into the L1 blockchain as necessary and inevitable.
