Ethereum devs to shutter Ropsten, Rinkeby and Kiln testnets after merge
Bringing The Merge to the tetsnets is essential to ensure the upgrade works well before the mainnet launch in early August if everything goes according to schedule.
The Ethereum core development team has announced a plan to shut down three of its existing testnets — Ropsten, Kiln and Rinkeby — after the so-called merge. Post-merge, the team plans to maintain only two existing testnets, Goerli and Sepolia.
