I want to develop a smart contract using the ERC-3643 standard instead of ERC-20. Could you guide me on how to integrate this standard into my contract? Any assistance would be greatly appreciated. Thank you!

You've come to the right place, as one of the co-authors of the ERC-3643, I can guide you on how to get started.

First of all, the core contracts of ERC-3643 include the following:

  • Token
  • IdentityRegistry (IdentityRegistryStorage is optional)
  • ClaimIssuer
  • ClaimRegistry
  • Compliance.

Here's how you can proceed:

  • Official Repo of the T-REX (ERC-3643): at https://github.com/TokenySolutions/T-REX for comprehensive information on the ERC-3643 standard.

  • Decentralized Identity: ERC-3643 uses OnchainID (https://github.com/onchain-id) for decentralized identity management, which is a crucial part of the standard

  • Understanding Deployment Order: I recommend reading the test files in the T-REX repo to understand how the contracts are deployed and their order. It would be too lengthy to detail here, but examining the tests will give you a clear understanding of the process.

  • Continuous Updates: Remember that the ERC-3643 might have changed since its initial release, as Tokeny, the company behind the standard, continuously updates and refines it.

Here is a simple infographic explaining the T-Rex Standard (ERC-3643) from three years ago, Keep in mind that the core principles are still relevant, but some details may have changed or been updated since then: ERC-3643 (T-Rex) Standard

  • Thanks! How can I verify the identity(addClaim) of the smart contract since I want to transfer the tokens into the smart contract ? Error is : Permissions: Sender does not have claim signer key Apr 25, 2023 at 12:58
  • The issuer that has been added to the ClaimIssuer should add a claim to the Identity (sender) that requires the claim.
