EthStorage

EthStorage is a layer-2 (L2) solution that provides programmable dynamic storage based on the availability of data on Ethereum. It will significantly reduce the storage costs for large amounts of data on Ethereum, saving 99% or even more, and better support the future of a fully decentralized network. EthStorage is highly integrated with the EVM and is fully compatible with Ethereum tools such as Solidity, Remix, Hardhat, and MetaMask. The team has received funding from the Ethereum Foundation for research on data availability.
