USDT, the world’s largest stablecoin, has long faced two major problems: liquidity fragmentation and scalability across multiple blockchains. A new solution, OpenUSDT (oUSDT), aims to fix this.
Built through a partnership between Chainlink, Hyperlane, and Velodrome, OpenUSDT is an interoperable version of USDT designed for the OP Superchain ecosystem. The OP Superchain consists of 30+ live blockchains with dozens more in development.
With Hyperlane’s cross-chain framework and Chainlink’s security infrastructure, OpenUSDT can move across different Superchain networks, solving key challenges that have restricted stablecoin adoption.

USDT is the most widely used stablecoin, with a market capitalization of over $141 billion. However, as the crypto industry grows, USDT faces two key limitations:
Liquidity Fragmentation
Scaling to Many Chains
OpenUSDT directly addresses these issues by making USDT natively interoperable across Superchain networks.
OpenUSDT is a cross-chain version of USDT designed to work seamlessly across Superchain networks. It is built on Hyperlane’s interoperability framework and secured using Chainlink’s Cross-Chain Interoperability Protocol (CCIP).
Interoperability – Works across all Superchain networks without needing custom bridge deployments.
Permissionless Expansion – Any new Superchain network can integrate OpenUSDT without requiring approval.
Seamless Upgrades – Can transition to native USDT minting on each chain as needed.
Enhanced Security – Secured by Chainlink CCIP and Hyperlane’s Modular Security framework.
Low-Cost & Efficient – Eliminates third-party bridge fees, making cross-chain transactions cheaper and faster.
Currently, only Celo within the OP Superchain has natively minted USDT. OpenUSDT solves liquidity fragmentation by using Celo as the minting hub:
This unified liquidity model ensures that all Superchain networks share the same USDT liquidity, preventing fragmentation.
At launch, OpenUSDT is available on:
More Superchain networks will be added over time as the ecosystem expands.
To ensure strong liquidity for OpenUSDT, Velodrome has been chosen as its primary trading venue. Velodrome is one of the largest decentralized exchanges (DEXs) in the OP Superchain ecosystem, making it the ideal place to trade OpenUSDT.
Per reports, by launching OpenUSDT liquidity pools on Velodrome, traders and DeFi users can easily swap, lend, and borrow OpenUSDT across multiple Superchain networks without fragmentation.
OpenUSDT is reportedly a step toward Ethereum becoming the leading global payment and DeFi settlement layer.
According to Celo Co-Founder Rene Reinsberg, OpenUSDT will help Ethereum achieve:
By enabling free, permissionless access to USDT, OpenUSDT aligns with the Superchain’s interoperability goals while ensuring long-term stability and adoption.
OpenUSDT expanding to new blockchains is made possible by Hyperlane’s permissionless deployment model, which allows anyone to integrate OpenUSDT into new Superchain networks.
Modular Security: Allows integration of future security mechanisms, including Chainlink CCIP and native Superchain interoperability.
Future-Proofing: OpenUSDT can seamlessly transition to native USDT minting whenever Tether expands to new chains.
ERC-7802 Compatibility: OpenUSDT is designed to work with Ethereum’s new cross-chain standard, ensuring long-term scalability.
For years, stablecoin providers have struggled to create a single, unified version of USDT that works across multiple chains without fragmentation. OpenUSDT could be the missing piece.
For everyday DeFi users, OpenUSDT offers several practical benefits:
Celo Co-Founder and Foundation President Rene Reinsberg emphasized the strategic importance:
“OpenUSDT is a future-proof product accelerating the accessibility and adoption of Tether’s USDT stablecoin within the Superchain ecosystem; helping Ethereum become the leading settlement layer for global payments and decentralized finance.”
