- Since The Merge last fall, Ethereum’s public testnets have gone through multiple major transformations, including the shut down of Goerli. While developers are migrating from Goerli to Sepolia, major NFT platforms have yet to make the transition.
Since completion of The Merge on Ethereum mainnet in September 2022, we have witnessed significant changes in Ethereum’s public testnets. Ropsten, the longest-serving testnet, was officially shut down in December 2022. Goerli, the most popular testnet at the moment, was deprecated in January 2023 but will continue to be supported for the rest of the year. Rinkeby, which was not updated to the Proof-of-Stake consensus mechanism during The Merge, is being deprecated mid-2023. Therefore, developers have begun migrating their test applications to Sepolia, a younger Ethereum testnet.
A lot of frustration occurred when many Goerli faucets were wound down earlier in the year, since Goerli is and remains the most popular Ethereum testnet. We were surprised to find that, at the time of writing, all major NFT marketplaces only support Goerli or Rinkeby. No NFT marketplace supports Sepolia yet.
Below is a table of popular platforms for creating NFTs (that do not require registration) and their current mainnet and testnet compatibility:
What does this mean for NFT creators? It is more difficult to get Goerli, with additional constraints and limits on many faucets, but not impossible. We recommend trying the active Goerli faucets compiled in our previous blog post and using Goerli ETH sparingly. We hope more platforms support Sepolia soon.
