SEP-0004: The Abstract Token Standard

SEP Specifications

SEP: 0004
Title: The Abstract Token Standard
Author: Chris Walker
Network: any EVM
Type: Request for Enhancement
Status: Proposed
Created: 2023-02-24
Proposal: New token standard for free mints

Simple Summary

  • The abstract token standard lets participants move tokens on- and off-chain as desired, enabling high-volume, zero-cost mints while preserving on-chain composability.*

Abstract

Abstract tokens provide a standard interface on EVM blockchains to:

  • Mint tokens off-chain as messages
  • Reify tokens on-chain via smart contract
  • De-reify tokens back into messages

Abstract tokens can comply with existing standards like ERC20, ERC721, and ERC1155, and are especially suited for token applications like airdrops, receipts, credentials, and a new form of bridging.
