Coverage vs. indexing the ENS Subgraph with no rainbow tables as of 8 March, 2025.
Our goal is to heal as many ENS names as possible. The ENS community has better things to do than learn about technical complexities like unknown names or encoded labelhashes.
ENSRainbow is a sidecar service for ENSNode, the new multichain indexer for ENSv2.
