Did you ever chased the RPC endpoint for a given chain ? or maybe some chain specs ? Did you ever wonder about the name or goal of the testnet of project XYZ ?
I am happy to announce the availbility of the [Polkadot Network Directory](https://github.com/paritytech/polkadot_network_directory) 🎉 .
This project has been kicked off thanks to @santi and @pierre.besson.
This repository is still in its early days but is now accepting submissions. Teams can submit a PR adding a yaml file looking like [this one](https://github.com/paritytech/polkadot_network_directory/blob/53304d90e1b74c09a6b56719b7f4a77132655192/chain_info/Westmint.yaml). Once a PR is merged, the information about the submitted chain will show up in the generated [book](https://paritytech.github.io/polkadot_network_directory/).
Additionnally, all the data of the directory is also available in the form of json files such as:
- [the full data](https://paritytech.github.io/polkadot_network_directory/chains.json)
- [the rpc endpoint registry](https://paritytech.github.io/polkadot_network_directory/registry.json)
Whether your project is a:
- relay chain / parachain / solo chain
- testnet / mainnet / canarynet
we made it cosy to host everyone.
Contribs are welcome, spread the word !

Talisman also has, `Chain Data` which is OS and can be viewed here → [GitHub - TalismanSociety/chaindata: A central repository of DotSama chain information indexed by chain id.](https://github.com/TalismanSociety/chaindata)
