Token Standards

Plume supports a variety of token standards to represent the full spectrum of use cases across all categories of real world assets. Asset issuers can tokenize their assets directly from the Plume Admin Dashboard and deploy any of these token contracts with a single click. Here is a table outlining our supported token standards and their respective use cases:

Token StandardDescriptionExamples of Real World Assets

ERC-20 Token Standard

Fungible tokens that are not investment contracts (no expectation of profits, not fractionalized)

  • Cryptocurrencies and stablecoins that can be exchanged for physical services

  • Loyalty points at restaurants, airlines, retailers, sports teams, etc.

  • Carbon offset credits

ERC-721 Non-Fungible Token Standard

Non-fungible tokens that are not investment contracts

  • Complete artworks like paintings, sculptures, prints, artifacts, etc.

  • Individual casks of whiskey

  • Intellectual property from patents, trademarks, copyrights, etc.

ERC-1155 Multi Token Standard

Semi-fungible tokens that are not investment contracts

  • Rare physical collectibles like stamps, coins, Pokemon cards, etc.

  • Resources and items in online games

  • Tradable tickets to physical events

  • Physical IoT devices

ERC-3643 T-REX - Token for Regulated EXchanges

Fungible security tokens

  • Investments in physical projects like solar farms, infrastructure, mining, etc.

  • Commercial and residential real estate

  • Commodities like precious metals, crude oil, agricultural products, etc.

  • Stocks, bonds, and other instruments

ERC-3643: T-REX - Token for Regulated EXchanges

ERC-3643 defines a token standard that can represent institutional-grade security tokens in a compliant manner. Asset issuers that tokenize their real world assets using ERC-3643 have access to interfaces that set transfer restrictions, freeze tokens, burn tokens, and forcibly transfer tokens—all critical actions for tokenized representations of real world assets regulated by securities agencies.

ERC-3643 was developed by Tokeny and submitted as an EIP in July 2021, and Tokeny has also developed an open-source reference implementation on GitHub. The standard is completely ERC-20 compatible, as it implements all required ERC-20 methods and events (

Relevant Unsupported Token Standards

We have chosen not to support certain relevant token standards for the initial launch of Plume. Many of these standards have low adoption among the community and only a single reference implementation. We will consider supporting some of these token standards only at the request of a dedicated RWA project that wants to onboard to Plume.

In particular, we do not support any of the finalized soul-bound token standards. The primary use case of soul-bound tokens in an ecosystem for real-world assets is to attest to user identities and accreditation status, which will instead be provided by the ONCHAINID system, with native integration for the ERC-3643 T-REX standard. The existing soul-bound token standards offer minimum functionality above the base ERC-721 NFT standard and have seen no serious adoption.
