Devnet is a test network that serves as a preview of coming attractions, where unstable changes are tested. Developers can use this network to try features and amendments which are not yet enabled on Mainnet.
AMM-Devnet is a test network for development and testing purposes. Unlike Mainnet,
AMM-Devnet is operated by RippleX for testing purposes. Due to a
change made to the AMM implementation, it was necessary to reset the AMM-Devnet network and ledger, deleting existing accounts and other ledger objects. The reset took place at approximately 1:30 AM UTC on September 6, 2023.
