RFC-0108: Remove XCM testnet NetworkIds
Start Date23 July 2024
DescriptionRemove the NetworkIds for testnets Westend and Rococo
Authors

Summary

This RFC aims to remove the NetworkIds of Westend and Rococo, arguing that testnets shouldn't go in the language.

Motivation

We've already seen the plans to phase out Rococo and Paseo has appeared. Instead of constantly changing the testnets included in the language, we should favor specifying them via their genesis hash, using NetworkId::ByGenesis.

Stakeholders

  • Runtime devs
  • Wallets
  • dApps

Explanation

Remove Westend and Rococo from the included NetworkIds in the language.

Drawbacks

This RFC will make it less convenient to specify a testnet, but not by a large amount.

Testing, Security, and Privacy

None.

Performance, Ergonomics, and Compatibility

Performance

None.

Ergonomics

It will very slightly reduce the ergonomics of testnet developers but improve the stability of the language.

Compatibility

NetworkId::Rococo and NetworkId::Westend can just use NetworkId::ByGenesis, as can other testnets.

Prior Art and References
