Token Requirements

Technical standards and protocols for tokenized assets, including supported blockchains, smart contract audits, and token functionality.

General Token Requirements

• Tokens must be deployed on supported DLT networks: Polygon PoS, Stellar Network, or Solana (in preparation).

• Smart contracts must be audited or use widely audited code (e.g., OpenZeppelin).

• Tokens must not disrupt trading or settlement processes.

Technical Requirements by Network

• Polygon PoS: Tokens must adhere to the ERC-20 standard.

• Stellar Network: Tokens must implement the SEP-41 interface.

• Further EVM and non-EVM chains will be enabled soon.

FAQ

Can a token listed on 21X be freely transferable?

Yes, but the issuer must ensure compliance with applicable laws and regulations.

Does the token require admin rights (e.g., clawback, burn & re-issue)?

No, from a technical standpoint, the minimum token requirements such as ERC-20 compatibility (Polygon PoS) or SEP-41 compatibility (Stellar Network) need to be met. The issuer must ensure compliance with applicable laws and regulations.

What protocols does 21X support?

21X currently supports Polygon PoS and Stellar Network. Further network support is in preparation.
