I’m not sure if below is something you can change or is part of global standard.
Currently, the payment link used for sending/receiving funds in TrustWallet has the following syntax:
bnb:bnb1ultyhpw2p2ktvr68swz56570lgj2rdsadq3ym2?amount=1.23456&memo=S0032415 binance gbp stable coin:bnb1ultyhpw2p2ktvr68swz56570lgj2rdsadq3ym2?amount=1.23456&memo=S0032415
None of above contain information about platform (‘bitcoin’, ‘bep2’, ‘erc20’ etc.). Some links use currency symbols and others their verbal names what makes it pretty frustrating to generate them automatically in the application. Spaces in currency name are even more troublesome especially for apps parsing links automatically.
I suggest to introduce the following syntax (optional components in square brackets):
‘platform’ is specified as (‘bitcoin’, ‘bep2’, ‘erc20’ etc.)
‘symbol’ is a currency symbol (or original symbol) unique within given platform, e.g. ‘BNB’ or ‘BGBP’ (or ‘BGBP-CF3’). This component could be omitted when using single currency platform like ‘bitcoin’ or when creating general transfer link for any currency running on given platform.

Furthermore it would be easier to specify which wallet application should handle requests for which platform e.g. ‘bitcoin:’ would open standard BTC wallet and ‘bep2:’ or ‘erc20’ would open TrustWallet.
