Fungible Asset and Digital Asset (NFT) are 2 Standards on Aptos

Unlike Solana, where Fungible Asset and Digital Asset shares the same standard (i.e. they use the same SPL token program). Aptos separates them into 2 standards similar to ERC-20 and ERC-721 on Ethereum.

Fungible Asset is not Widely Supported by DEXes on Aptos Yet

Aptos has 2 ERC-20 like standards. The legacy one is called Coin, the new one is called Fungible Asset. As of April 2024, we are in the process of migrating from Coin to Fungible Asset. Majority DEXes on Aptos today only support Coin. If you want to build a launchpad on Aptos mainnet, you need to use Coin. You can follow the migration PR on GitHub.
