USD.AI has expanded its two core tokens, USDai and sUSDai, to Solana, using LayerZero's Omnichain Fungible Token (OFT) standard for cross-chain transfers. The rollout went live on September 24, 2026, at approximately 17:52 UTC, and on-chain activity followed quickly: roughly 8.43 million sUSDai, valued at around $9.39 million, bridged to Solana within hours of launch, according to the protocol's figures. The token also recorded $372,000 in decentralized exchange trading volume in its first 24 hours.

The expansion marks the protocol's first move outside EVM-compatible chains. Before this launch, USDai and sUSDai existed only within the EVM ecosystem, where the protocol already relied on LayerZero for cross-chain movement. Solana does not run the Ethereum Virtual Machine, so reaching it required stepping beyond that infrastructure entirely. The OFT standard allows a token to move between networks without spawning a wrapped or synthetic copy on the destination chain.

USD.AI published the official Solana contract addresses alongside the launch. USDai sits at USDai5XCUzNebYzUk6EuRiFCvnyoyEdj7VSyijYcz2A, and sUSDai sits at sUSDai6Y3GxysDEtA9BVcEFTaog6UZpYUVxJiMhAKYE. The protocol advised users to verify addresses before transacting, citing the risk of lookalike tokens on newly supported chains.

How the tokens work

USDai is the base asset. Depositors mint it with existing stablecoins. sUSDai is the staked version: holders lock USDai and receive a yield-bearing receipt token. The yield derives from interest paid on loans that the protocol issues against AI infrastructure.

That credit business sits at the center of the model. USD.AI operates a lending system that extends credit to operators in the AI sector, with loans secured by GPU hardware — the specialized chips used for AI model training and inference. The loan book exceeds $280 million across 16 separate facilities, according to the protocol. The largest single facility, at $128.9 million, is backed by 2,304 NVIDIA GB200 GPUs.

That concentration carries operational weight. One facility accounts for a large share of the total book, so its performance matters more than any other single loan. Holders of sUSDai, whether on an EVM chain or Solana, remain exposed to the same underlying risk: AI infrastructure operators repaying GPU-secured debt.

Solana integrations and incentives

At launch, USD.AI lined up integrations with six Solana DeFi protocols: Jupiter Lend, Kamino, Orca, Loopscale, Exponent, and Mezzanine. The set gives holders options for lending, liquidity provision, and trading in fixed-rate markets. A meaningful share of the bridged sUSDai has already been deployed across Kamino and Jupiter Lend for lending, and Orca, where users supply trading liquidity.

For the first eight weeks, eligible users can earn ALLO points, plus additional incentives offered by USD.AI. The points program runs alongside the protocol's existing reward mechanics and is time-limited to the post-launch window.

What the numbers signal

The first-day figures point to genuine demand for Solana access. Roughly $9.39 million in bridged sUSDai and $372,000 in trading volume are modest next to a $280 million-plus loan book, but they arrived within hours rather than weeks. For sUSDai holders, the expansion adds deployment flexibility without changing the underlying exposure, since the yield source remains the GPU-secured credit portfolio regardless of chain.

Cross-chain expansion also introduces its own dependencies. Token movement between networks relies on the messaging infrastructure behind the OFT standard functioning as intended, and any interruption would affect liquidity flows between EVM chains and Solana.

The eight-week ALLO points window now sets the near-term clock: how much of the bridged capital stays deployed in Solana DeFi after incentives taper will offer the first real test of whether this expansion reflects durable demand or a launch-driven spike.
