Adds a CAIP-19 asset profile to the existing
aptosnamespace. The CAIP-2 profile is already ratified and is not touched.Who wrote this
I do not represent the aptos ecosystem. I maintain FAR, an open cross-reference between CAIP-19, CoinGecko and ISO 24165 (DTI) identifiers, which needs a way to name 64 assets on this chain. CASA's README invites profiles added to an existing namespace, so this documents how assets are addressed rather than claiming to speak for anyone. Offered for the aptos community to correct, adopt or replace.
Asset namespaces
slip44, coin, aip21, aip11, tokenv1What this profile establishes
Two namespaces for Coin and Fungible Asset, not one. They are different reference grammars (type tag vs bare address), and merging them would assert an equivalence the chain does not guarantee. Proven in both directions on chain:
paired_metadata<AptosCoin>→0xa,paired_coin(0xa)→ module hex decoding toaptos_coin. But the inverse fails —paired_coinfor Circle's USDC returns empty, because it is FA-native. Code assuming every fungible has a Coin type silently drops most new stablecoins.APT has three identifiers (
slip44:637, the Coin type, andaip21:0xa), so the profile sets a canonical one.Namespaces use AIP numbers following the Stellar profile's
