Circle's Poloniex crypto exchange added support for Tether's USDT stablecoin as a token on Tron's blockchain. In March, Tether announced its implementation of USDT stablecoin as a Tron-based TRC-20 token. Tether started issuing USDT on the Tron blockchain on April 17, CoinTelegraph reports, which is a move to allow Tron smart contracts to use the stablecoin.
