should we use the chains repo to autogenerate our Ethereum networks?

should we use the chains repo to autogenerate our Ethereum networks?

I think that's a good idea

[matejcik]

what is the SLIP44 ID for binance? are they using the same 714 for this and their native chain? i don't think that's a particularly good idea

[matejcik]

they also seem to use the same BNB symbol. not that great either, seeing as there's currently no way for the user to distinguish between the network they're transacting on

[matejcik]

BNB smartchain is added in #1345

we are waiting for https://github.com/ethereum-lists/tokens/pull/435, this is waiting for Trustwallet's modifications

We already have the data from coingecko, so the token is now supported.
