Polygon spinoff launches testnet bridge to allow for low-cost layer-2s
Avail launched a bridge to transmit data availability attestations to Ethereum, potentially allowing for lower fees on some L2s. Blockchain network Avail has launch ed a testnet data availability bridge to Ethereum, according to a July 7 announcement. Once testing is completed, the bridge will allow developers to easily create “validiums” or low-cost layer-2 s that do not store full transaction data on Ethereum, the announcement stated. Avail was originally created by Polygon Labs, but was spun off as an independent project in March. Polygon’s co-founder, Anurag Arjun, is also the founder of Avail. Avail Block Explorer.

However, because these networks must write all the transactions to the base layer, they often have higher transaction fees than layer-1 c...
