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. 

Following the news Tether Announces Strategic Transition to Prioritize Community-Driven Blockchain Support on 24th June 2024, Tether stopped minting USD₮ on EOS and Algorand

Following the latest update, the transition process will move forward as follows:

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

• Tether ceased minting USD₮-EOS and USD₮–Algorand from 24th June 2024.

• Tether will no longer be obligated to accept redemptions of USD₮ or EUR₮ on Omni, Kusama, SLP, EOS and Algorand starting on September 1, 2025.

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

• Tether will freeze all remaining USD₮ and EUR₮ on Omni, Kusama, SLP, EOS and Algorand on September 1, 2025.

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:

exception: Tether’s current USD₮ ERC20 contract is based on a slightly older standard that does not return a Boolean value in the transfer function.
