aptos-registry

A TokenRegistry that keeps track of a list of Tokens.

Currently these are tracked:

struct TokenInfo has store, drop, copy {
    name: ASCII::String,
    symbol: ASCII::String,
    description: ASCII::String,
    decimals: u8,
    logo_url: ASCII::String,
    project_url: ASCII::String,
    delisted: bool,
    token_type: TypeInfo::TypeInfo,
}

This is what the registry looks like right now:

struct TokenRegistry has key {
    admin: address,
    // for easier lookup of individual TokenInfo
    symbol_to_token_info: Table::Table<ASCII::String, TokenInfo>,
    // for checking TypeInfo doesn't already exist in our type
    type_info_to_symbol: Table::Table<TypeInfo::TypeInfo, ASCII::String>,
    // for faster edits
    symbol_to_list_idx: Table::Table<ASCII::String, u64>,
    // for easier lookup of the full list
    token_info_list: vector<TokenInfo>,
}

token_info_list has the full list.

All tracked tokens need to have unique symbol and token_type.

Tokens can be delisted via delist_token and modified via update_token_info.

Currently only a single admin is able to modify the registry. We'll add some vote features so that it becomes a registry that can be managed by a voting community.
