USDT has been the lifeblood of DeFi for many years, and Chainlink is excited to support it further by supporting OpenUSDT interoperability, making it possible to seamlessly bring USDT anywhere on any Optimism chain. Chainlink's full tech stack will be unleashed for the adoption of USDT in the Optimism ecosystem with both Chainlink Data Feeds and Chainlink CCIP being used to make the adoption of USDT seamless for DeFi developers looking to use the largest stablecoin in the space.
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.
With sub-cent transaction fees, stablecoin gas payments, seamless on- and off-ramps, and as the only Layer-2 with native USDT following Celo’s migration next month, serving as the backbone for OpenUSDT is a way for us to realize this vision. We’re excited to support this amazing initiative alongside Chainlink and Hyperlane, and make our welcome contribution as we join the Superchain family and move towards Ethereum Layer-2 interoperability.
OpenUSDT is a seminal moment for interoperability in the Superchain. As the open framework for interop, Hyperlane uniquely allows OpenUSDT to expand to any chain easily. OpenUSDT will be able to grow with the Superchain even as new rollups launch.
As the primary trading and liquidity hub of the Superchain, Velodrome couldn't be more excited to support the launch of OpenUSDT. A strong ecosystem of interoperable stablecoins will be essential for Superchain builders and users, and Velodrome will be their hub.
