Dear users:
To provide more contract trading options and improve the trading experience, the TEBBIT Contracts platform will officially launch the following USDT-margined perpetual contracts at 20:00 (UTC+8) on September 14, 2026, with leverage of up to 50x:
I. Token Introduction:
BR/USDT
Bedrock supports restaking/staking multiple assets, including: brBTC: brBTC represents Bedrock BTC and is designed for Bitcoin holders seeking to participate in next-generation DeFi opportunities. It accepts uniBTC and various wrapped BTC assets, and Bedrock manages these assets across multiple trusted yield-source layers, such as Babylon, Kernel, Pell, and Satlayer. uniBTC: A restaking protocol that accepts wrapped BTC tokens and collaborates with Babylon, a BTC staking protocol. The first supported wrapped BTC is the wBTC token on the Ethereum blockchain, so all wBTC token holders can enjoy the yield from staking BTC tokens and the security of the Ethereum network. uniETH: Bedrock is designed to natively restake and utilise additional EigenLayer rewards, combining institutional-grade security with the additional yield of liquid-staked ETH. uniIOTX: A liquid staking solution on the IoTeX blockchain that eliminates several drawbacks of delegated proof-of-stake on IOTX.
AIN/USDT
Infinity Ground is a leading blockchain infrastructure built for Vibe Coders, creating an agent-driven development environment free from centralised limitations. The platform is built around three core pillars: the first decentralised agent IDE, which enables anyone to create DApps—including games, social applications, and DeFi applications—using natural language without programming; an AI app store for publishing and monetising creations; and a scalable public blockchain designed for Vibe Coders—the ING Network. In early 2025, Infinity Ground completed a US$2 million seed funding round. The project is backed by several leading investment institutions, including Frachtis Ventures, MarbleX, MHVentures, Animoca Brands, KnightFury, Presto Labs, UFLY Labs, and PAKA, and is leading a new era of AI-native applications for the general public.
