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 integrator 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:

• Omni Protocol Token via Bitcoin Blockchain;

• ERC20 Token via Ethereum Blockchain, Avalanche Blockchain and Polygon Blockchain;

• TRC20 Token via Tron Blockchain;

• EOSIO.TOKEN via EOS Blockchain;

• Liquid Asset via Liquid Blockchain;

• Algorand Asset via Algorand Blockchain;

• SLP Token via Bitcoin Cash Blockchain;

• Solana Token via Solana Blockchain;

• Statemine Asset via Kusama Network;

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 a 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 as well as 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:

ERC20 Token via Ethereum Blockchain, Avalanche and Polygon Blockchain

Ethereum Network

Support for Tether tokens in your project can be added with the following contract addresses:

USD₮ contract address: 

https://etherscan.io/token/0xdac17f958d2ee523a2206206994597c13d831ec7

EUR₮ contract address: 

https://etherscan.io/token/0xC581b735A1688071A1746c968e0798D642EDE491

CNH₮ contract address: 

https://etherscan.io/token/0x6e109e9dd7fa1a58bc3eff667e8e41fc3cc07aef

XAU₮ contract address: 

https://etherscan.io/token/0x68749665FF8D2d112Fa859AA293F07A622782F38

MXN₮ contract address:

https://etherscan.io/token/0xed03ed872159e199065401b6d0d487d78d9464aa

Note: The integration path is the same as any ERC20 compatible token with the following

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. Developers and Integrators deploying their own custom contracts should take care and use the SafeERC20 library which is designed to handle both the old and new standards.

Avalanche Blockchain

Support for Tether tokens in your project can be added with the following contract addresses:

USD₮ contract address: 

https://snowtrace.io/token/0x9702230a8ea53601f5cd2dc00fdbc13d4df4a8c7 

Note: The integration path is the same as any ERC20 compatible token

Polygon Blockchain

Support for Tether tokens in your project can be added with the following contract addresses:

USD₮ contract address: 

https://polygonscan.com/address/0x170a18b9190669cda08965562745a323c907e5ec

MXN₮ contract address:
