<a href="https://x.com/USDai_Official" rel="noopener noreferrer nofollow">@USDai_Official</a> has extended its dollar-pegged stablecoin USDai and its yield-bearing counterpart sUSDai to five blockchains: Arbitrum, Ethereum, Plasma, Base, and Solana. The expansion uses LayerZero's Omnichain Fungible Token (OFT) standard, which means the assets travel between networks as the same canonical token rather than wrapped copies.
<cite>Transfers run on the OFT standard. A token issued under it can cross from one blockchain to another without becoming a knockoff version of itself on arrival.</cite> In practice, <cite>a token built as an OFT exists natively on every chain it supports. When you send it cross-chain, the token is burned on the source and minted on the destination.</cite> This keeps total supply consistent and eliminates the fragmented liquidity that has historically plagued wrapped-token bridges.
<cite>Before this launch, USDai and sUSDai lived only on EVM-compatible chains. The protocol already used LayerZero for cross-chain movement within that family. Solana does not run the EVM, so reaching it means stepping outside that ecosystem entirely.</cite>
<h2 id="yield-backed-by-ai-infrastructure">Yield Backed by AI Infrastructure</h2>
sUSDai is the staked version of USDai. <cite>Holders lock up USDai and receive a token that earns yield, which comes from interest paid on loans the protocol issues.</cite> Those loans finance GPU hardware for AI data centers, connecting the stablecoin's yield directly to demand for artificial intelligence compute.
<cite>At launch, USD.AI lined up integrations with six Solana DeFi protocols: Jupiter Lend, Kamino, Orca, Loopscale, Exponent, and Mezzanine.</cite><cite>Roughly $9.39 million in bridged sUSDai and $372,000 in trading volume arrived within hours rather than weeks.</cite>
<cite>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.</cite> For context, <cite>LayerZero's OFT standard now handles 87% of all cross-chain token transfer volume, managing about $44 billion in assets across more than 100 blockchains.</cite>
