USDai and sUSDai expand to Solana with cross-chain transfers via OFT

USD.AI has brought its two tokens, USDai and sUSDai, to Solana. Both now support cross-chain transfers using the OFT standard.

Approximately 8.43 million sUSDai, valued at around $9.39 million, moved over to Solana within hours of going live. The token also logged $372,000 in decentralized exchange trading volume over the first 24 hours.

What actually launched

The rollout went live on September 24, 2026, at roughly 17:52 UTC. It covers both of the protocol’s core products.

USDai is the base token. Depositors mint it using existing stablecoins, much like trading dollars for casino chips before sitting down at a table.

sUSDai is the staked version. Holders lock up USDai and receive a token that earns yield, which comes from interest paid on loans the protocol issues.

The transfers run on the OFT, or Omnichain Fungible Token, standard. A token issued under it can cross from one blockchain to another without becoming a knockoff version of itself on arrival.

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.

For anyone who wants to verify they hold the real thing, USD.AI listed the Solana addresses. USDai sits at USDai5XCUzNebYzUk6EuRiFCvnyoyEdj7VSyijYcz2A. sUSDai sits at sUSDai6Y3GxysDEtA9BVcEFTaog6UZpYUVxJiMhAKYE.

Where the money went

At launch, USD.AI lined up integrations with six Solana DeFi protocols: Jupiter Lend, Kamino, Orca, Loopscale, Exponent, and Mezzanine. That gives holders options for lending, providing liquidity, and trading in fixed-rate markets.

A meaningful share of the bridged sUSDai has already been put to work across Kamino, Jupiter Lend, and Orca. Kamino and Jupiter Lend handle lending, while Orca is a decentralized exchange where users supply trading liquidity.

For the first eight weeks, eligible users can earn ALLO points, plus additional incentives offered by USD.AI.

The GPU loans underneath

The protocol runs a credit system that lends to infrastructure operators in the AI sector. Those loans are secured by GPU hardware, the specialized chips that power AI model training and inference.

The underlying loan book totals more than $280 million, spread across 16 separate facilities. The largest single facility listed is $128.9 million, backed by 2,304 NVIDIA GB200 GPUs.

That concentration is worth noting. One facility accounts for a large portion of the total book, so its performance matters more than any other single loan.

What this means

For USD.AI, the first-day figures point to real demand for access on Solana. Roughly $9.39 million in bridged sUSDai and $372,000 in trading volume are modest next to the $280 million-plus loan book, but they arrived within hours rather than weeks.

For sUSDai holders, the move adds flexibility without changing the underlying exposure. Whether the token sits on an EVM chain or Solana, its yield still depends on AI infrastructure operators repaying loans secured by GPUs.

Cross-chain setups also carry their own considerations. Moving tokens between networks relies on the messaging infrastructure behind the OFT standard working as intended. Users taking advantage of the new routes should confirm the official token addresses before transacting, since lookalike tokens are a familiar hazard on any newly supported chain.
