ما هو BLOCKCHAIN USD(USDB)؟

Blockchain USD (USDB) is a USD-pegged stablecoin built for payments and trading on centralized and decentralized exchanges. The project published USDB in 2023 and deployed an ERC-20 version on Robinhood Chain on 31 August 2026. The Robinhood Chain contract is 0x65f1F83DD8b702a195e24eA171f8136fB1888888. Official materials describe USDB as a payment stablecoin intended to keep a value near one US dollar for transfers, liquidity, and settlement. Project information is published at https://atlantischain.org/USDB/. Community channels are https://x.com/Blockchain_USD and https://t.me/USDB_Web3. On Robinhood Chain, USDB trades on Uniswap V3. The AtlantisChain site also describes an ATC-20 USDB version used inside that separate network. This listing request is for the live Robinhood Chain token, not for a preview or unlaunched asset.
