Supported Protocols and Integration Guidelines

We appreciate your interest in integrating TETHER tokens into your platform.

TETHER tokens exist on multiple blockchains and should be treated equally and interchangeably, i.e. 1 TETHER token on Blockchain X = 1 TETHER token on Blockchain Y.

Where possible, we request that integrators support as many of the protocols listed below as their platform currently supports/operates on and that it is made explicitly clear (both publicly and within their platform) which protocols they support.

Currently Supported Asset Protocols:

Following the news Tether Makes Strategic Transition, to Meet Community Demands and Foster Innovation on 17th August 2023, Tether discontinued support for the Kusama, Bitcoin Cash SLP and Omni Layer implementations. 

The transition process will move forward as follows:

  • Tether ceased minting USD₮-Omni, USD₮-Kusama, and USD₮–BCHSLP from 17th August 2023

  • Tether will continue to redeem USD₮-Omni, USD₮-Kusama, and USD₮-BCH-SLP as normal until September 2024. Tether may evaluate and announce further changes around that time. 

  • Users can also swap USD₮-Omni, USD₮-Kusama, and USD₮-BCH-SLP for other chains on platforms that support these assets, such as Bitfinex.

If you have questions about how to redeem your Tether, please contact our Customer Support team

Omni Protocol via Bitcoin Blockchain

Important: Tether’s assets created and issued on the Omni protocol are identified by the Omni Protocol Property ID: USD₮ #31 and EUR₮ #41.

Any other TETHER property identification number is fake.

Integration for Tether (and any Omni Protocol token) is achieved through the Omni Core client

Omni Core is a Bitcoin core clone that supports Bitcoin and all the Omni protocol currencies. Therefore, if you are building an exchange and integrating Bitcoin/Bitcoin core, the integration path/requirements for Omni Core would be almost identical.

Being built on top of Bitcoin core, Omni Core inherits all the RPC capabilities of Bitcoin core and adds a few additional Omni Protocol Specific RPC calls of its own.

Please see the Omni Core integration guide provided by the Omni team for the technical details needed to incorporate the client into your platform:
