USD.AI has expanded USDai and sUSDai to Solana using LayerZero's Omnichain Fungible Token (OFT) standard, enabling the assets to function as unified tokens across multiple networks. The stablecoins now support cross-chain transfers on Solana, Arbitrum, Ethereum, Plasma, and Base. LayerZero reported that cumulative cross-chain transfer volume facilitated through its OFT standard has surpassed $2 billion. This milestone underscores growing adoption of omnichain infrastructure for seamless asset movement between ecosystems.
