OpenUSDT has officially launched as an interoperable version of Tether’s USDT stablecoin. It was launched across seven blockchain networks within the OP Superchain ecosystem.
This development integrates one of the world’s largest stablecoins, with over $141 billion in market capitalization, across multiple chains. This is achieved through a unified framework that leverages Chainlink’s Cross-Chain Interoperability Protocol (CCIP) and Hyperlane’s interoperability infrastructure.
The solution addresses the long-standing issue of stablecoin liquidity fragmentation, which refers to the division and inefficiency of stablecoin assets across different blockchain networks. It also enables permissionless value transfers without vendor lock-in.
Multi-Chain Solution in Crypto Ecosystem
Before OpenUSDT, blockchains in the Superchain ecosystem faced a difficult choice when integrating USDT. Networks either had to deploy their own versions of bridged USDT or pay third parties to deploy token contracts.
This created inefficiencies that hindered the seamless flow of the world’s most widely used stablecoin across different networks. OpenUSDT resolves this challenge by providing a common, interoperable USDT implementation across multiple chains. The system uses Celo as the hub chain, and USDT is locked to mint OpenUSDT on other chains while maintaining a verifiable 1:1 backing.
This approach ensures that the stablecoin maintains its value peg. It simultaneously enables cross-chain transfers without the fragmentation that previously existed. OpenUSDT creates a secure and efficient way for USDT to move between blockchain networks.
The Seven Supported Networks
As of March 5, 2025, OpenUSDT is available on seven different blockchain networks within the Superchain ecosystem. These networks include Base, Fraxtal, Lisk, Mode, Optimism, Soneium, and Unichain.
This multi-chain availability creates unified liquidity for USDT across these networks. It will also enable more efficient capital allocation and cross-chain decentralized applications. The system is designed with expandability in mind, enabling rapid deployment to new Superchain networks with CCIP and Hyperlane. The expansion will be important because of the new rollups and layer 2 solutions joining the network.
Johann Eid, Chief Business Officer at Chainlink Labs, highlighted the importance of this development.
“USDT has been the lifeblood of DeFi for many years, and Chainlink is excited to support it further by supporting OpenUSDT interoperability…” Johann Eid, Chief Business Officer at Chainlink Labs stated.
He notes that Chainlink’s full technology stack is to streamline USDT adoption for developers. The collaborative approach taken by Chainlink, Hyperlane, Celo, and Velodrome demonstrates how different blockchain organizations can work together to create solutions that benefit the broader ecosystem.
