Permissioned v.s. Permissionless listing

• Getting into the permissionless list is easy. Just follow the steps above. Do note that, to avoid spam, we may require a small fee in the future for permissionless listing.

• Getting into the permissioned list requires that you establish enough brand presence and credibility within the Aptos ecosystem first. For example, you need to have been at least active enough to have already been added to one of those private Aptos Ecosystem telegram groups.

Fetching list

You can use the client provided to fetch an updated list from the chain, or you could fetch the json file from github directly:

• permissioned list
• permissionless list

Displaying RawCoinInfo

We recommend frontends display the following information for each coin:

• name: full coin name, usually includes project name
• official_symbol or symbol or hippo_symbol or pancake_symbol
• logo_url: coin logo

official_symbol or symbol or hippo_symbol or pancake_symbol

Aptos started out in a state where different protocols used different symbols for the same bridged token. This set of four symbols tries to capture all that variety in how coin symbols are displayed across the aptos ecosystem.

• official_symbol: this is the symbol registered by the token minter onchain
• symbol: similar to official_symbol, except if the coin is bridged from wormhole or layerzero. Layerzero coins are prefixed with z and many wormhole symbols are unprefixed
• hippo_symbol: similar to official_symbol, except: layerzero symbols use z prefix and wormhole symbols use w prefix
• pancake_symbol: similar to official_symbol, except: layerzero symbols use lz prefix and wormhole symbols use wh prefix

RawCoininfo

In a complete RawCoinInfo, we have these fields:

• name: coin name, preferrably include project name
• symbol: globally unique symbol within this coin registry
• official_symbol: same as aptos_framework::coin::CoinInfo.symbol, duplicates allowed
• coingecko_id: coingecko id. May be used by various clients to look up coin price
• logo_url: URL to token logo, preferrably a githubusercontent url
• project_url: URL to project
• token_type: token address info
• extensions: other informal info that you want to add, in the form of a list of string-string key-value pairs. Obsolete, no maintenance required
• unique_index: a unique numeric index within this list. There is any logical relationship with the token information, only need to ensure the uniqueness
• source: indicates if the token is from a bridge or native
• hippo_symbol: hippo-style prefixed symbols (wormhole uses "w" prefix, layerzero uses "z" prefix)
• pancake_symbol: pancake-style prefixed symbols (wormhole uses "wh" prefix, layerzero uses "lz" prefix)
