แปลง Treehouse ETH TETH เป็น Chain-key USDT CKUSDT

tETH is a liquid staking token (LST) that converges the fragmented on-chain ETH interest rates market. Holders of tETH earn real yield in excess of Ethereum’s Proof-of-Stake (PoS) rewards through interest rate arbitrage while still being able to use tETH for DeFi activities. tETH is also foundational to supporting the eventual implementation of Treehouse’s Decentralized Offered Rates (DOR) consensus mechanism as well as the Treehouse Actively Validated Service (AVS).

ckUSDT is a digital twin of USDT on the Internet Computer Protocol network. Fully backed 1:1 by USDT, ckUSDT is powered by Chain-key technology which allows for cross chain interoperability without centralized intermediaries or bridges. Canister smart contracts on ICP can integrate with the Ethereum network using a combination of replicated HTTPS outcalls to a known set of public Ethereum nodes to read state and submit transactions, and chain-key ECDSA (ckECDSA) signatures, an enhanced version of threshold ECDSA, to sign those submitted transactions. Building upon this integration framework, ckUSDT is a pair of canister smart contracts that utilize HTTPS outcalls and ckECDSA services. The ckETH minter and ckUSDT ledger contracts work together to enable users and smart contracts to send and receive USDT value within seconds with negligible transaction fees, and no gas fees, while also always allowing users and smart contracts to send and receive USDT value to and from the Ethereum network. ckUSDT exposes ICRC-1 and ICRC-2 ledger interfaces (the fungible token standards of ICP), making it simple for all wallets on the Internet Computer to offer ckUSDT support.
