PSP-22​

A standard for a fungible token interface for WebAssembly smart contracts which run on Substrate's contracts pallet.

This proposal aims to define the standard fungible token interface for WebAssembly smart contracts, just like EIP-20 for the Ethereum ecosystem.

PSP-34​

A standard for a Non-Fungible Token interface for WebAssembly smart contracts which run on Substrate's contracts pallet.

This proposal aims to define the standard Non-Fungible Token interface for WebAssembly smart contracts, just like EIP-721 for the Ethereum ecosystem.

PSP-37​

A standard for a Multi Token interface for WebAssembly smart contracts which run on Substrate's contracts pallet.

This proposal aims to define the standard Multi Token interface for WebAssembly smart contracts, just like EIP-1155 for the Ethereum ecosystem.
