@dc8ntinuum why change a current listing?

[dc8ntinuum]

Thanks for replying! We identified a Chain ID collision for 2184 (0x888).

Genesis block for c8ntinuum, Chain ID 2184:https://ctmscan.io/block/1

c8ntinuum has publicly used Chain ID 2184 since June 6, 2025, when we published wallet/RPC instructions for users:https://x.com/c8ntinuum/status/1931064479472918694

We have also submitted c8ntinuum/2184 to ethereum-lists/chains:ethereum-lists/chains#8565

There is another currently open/unmerged ethereum-lists PR requesting the same Chain ID:ethereum-lists/chains#8511

Since DefiLlama already has a current listing for 2184, we wanted to bring the collision to your attention rather than assume it should simply be overwritten.

Could you please advise on the correct procedure for resolving a Chain ID collision like this? We can provide additional historical and on-chain evidence of c8ntinuum’s prior use if needed.

Thank you!
