OpenUSDT

OpenUSDT is a future-proof interoperable USDT stablecoin enabling shared liquidity and interchain applications

The introduction of OpenUSDT solves a critical issue where chains 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 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: OpenUSDT (oUSDT).

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

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