Use ERC-3770 chain-specific prefixes instead of chain ID in the stream alias

[PaulRBerg]

Problem

The ID of a stream is a rather technical blob of information at the moment, e.g.

LK-42161-625 // contractAlias-chainId-tokenId

Specifically, the problems are:

1. It's not obvious that the 2nd number is the chain ID
2. 99% of users don't care about the chain ID anyway.

Solution

Replace the chain ID with the ERC-3770 chain-specific prefix, like so:

LK-ARB-625

And:

LK-OPT-625

About Backward-Compatibility

• The UI can remain backward-compatible by re-routing LK-42161-625 to LK-arb-625
• The indexers won't be backward-compatible. However, I think this is a worthwhile change that would improve the UX for end users. There shouldn't be any integrator depending upon the alias.

Feedback

cc @sablier-labs/frontend for feedback, WDYT?

I think it's a good idea, we've actually started implementing this in the client-sol (example).
