OpenUSDT

OpenUSDT is a future-proof interoperable USDT stablecoin for the OP Superchain enabling shared liquidity and interchain applications.

The introduction of OpenUSDT solves a critical issue where blockchains in the Superchain ecosystem are required to either deploy their own version of bridged USDT, resulting in liquidity fragmentation and limited interoperability, or must pay a third party for the privilege of deploying a bridged token contract. By avoiding vendor lock-in and instead focusing on creating positive flywheel effects, OpenUSDT aligns with the Superchain interoperability thesis by providing free access to the world’s largest stablecoin with $141B+ in market capitalization.

Users can easily swap OpenUSDT or use the OpenUSDT dApp to mint new OpenUSDT.

OpenUSDT is a joint effort by leading blockchain infrastructure providers and protocols including Chainlink, Hyperlane, and Velodrome collaborating to bring a new interoperable USDT token to the OP Superchain ecosystem: OpenUSDT (oUSDT).

Backed 1:1 with native USDT locked on Celo, OpenUSDT leverages Chainlink CCIP and Hyperlane for cross-chain transferability, creating open and unified liquidity for the world’s largest stablecoin within the Superchain.

Leveraging the Superchain ERC20 standard, the address of OpenUSDT on all OP chains is the same: 0x1217BfE6c773EEC6cc4A38b5Dc45B92292B6E189

Currently, OpenUSDT is available on the following chains, with native USDT on Celo acting as the hub. Additional networks can easily follow in the future:

• Base

• Fraxtal

• Lisk

• Mode

• Optimism

• Soneium

• Unichain

A detailed breakdown of the OpenUSDT infrastructure can be found on the Architecture page.
