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 Standard | Description | Examples of Real World Assets |
---|---|---|
ERC-20 Token Standard | Fungible tokens that are not investment contracts (no expectation of profits, not fractionalized) |
|
ERC-721 Non-Fungible Token Standard | Non-fungible tokens that are not investment contracts |
|
ERC-1155 Multi Token Standard | Semi-fungible tokens that are not investment contracts |
|
ERC-3643 T-REX - Token for Regulated EXchanges | Fungible security tokens |
|
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.
