Stella Developers Meeting covers USDT0, Tether's USDT delivered to Stellar via LayerZero's OFT standard. Live on mainnet since September with $2.58M in bridged assets, 23,717 accounts, and 7 DVN operators. Technical walkthrough of cross-chain architecture and developer capabilities for sending, receiving, and tracking stablecoins across 23 networks.
USDT0 on LayerZero represents a milestone in Stellar's cross-chain infrastructure. Tether's USDT moves to Stellar via LayerZero's OFT (Omnichain Fungible Token) standard, which keeps total supply invariant across 23 networks. On Stellar, adoption has grown rapidly: 23,717 accounts hold USDT0 trust lines (up from 13.5K in two weeks), with $2.58M locked in contracts. The technical architecture spans four contracts on Stellar: the classic USDT0 asset (with frozen issuer account), the SAC (Stellar Asset Contract), the SAC manager admin contract, and the OFT bridge contract. Messages flow through a 5-step process: Send > Verify (via DVNs) > Commit > Execute > Mint. Developers can read and interact with everything on-chain without keys or APIs; precise decimal handling (6 decimals on-wire prevents dust). Next week brings an AMA with USDT0 issuers and LayerZero integrators.
