Token registry design #1

Open shaunxw opened 3 years ago

shaunxw commented 3 years ago

Types

struct TokenInfo
- id: MultiLocation
- decimals: u8
- #cfg(feature = full) extra: ExtraTokenInfo
struct ExtraTokenInfo
- name: &'static str
- symbol: &'static str
- description: &' static str
- icon: Option<&'static str>

Traits

ReserveChainLocation: should be implemented by each TokenInfo.
- fn location() -> MultiLocation: returns the reserve chain location of a token.

Registry

mod polkadot
- mod acala
  - const ACA: TokenInfo
  - const aUSD: TokenInfo
  - const all: [TokenInfo] = [ACA, aUSD]
- mod plasm
  - use plasm_token_info::*
  - assuming Plasm have published their token info in crate plasm_token_info
mod kusama
- mod karura
  - const KAR: TokenInfo
  - const kUSD: TokenInfo
  - const all: [TokenInfo] = [KAR, kUSD]

Dump

Add a bin crate and script to dump JSON file.
- dump_token_info
  - generate a JSON file with all the token info

A registry would be extremely useful. Kudos to the proposal! For the TokenInfo struct, it might be helpful to add the associated coin-type from BIP-44. https://github.com/satoshilabs/slips/blob/master/slip-0044.md This would be helpful information for both hardware and software wallets like ledger.
