USDai and sUSDai Launch on Solana via OFT Cross-Chain

USD.AI Expands to Solana, Bringing Stablecoin and Staked Tokens

USD.AI has launched its USDai and sUSDai tokens on the Solana blockchain, enabling cross-chain transfers via the OFT standard. The move saw approximately 8.43 million sUSDai, valued at around $9.39 million, migrate to Solana within hours of the platform going live. The token also recorded $372,000 in decentralized exchange trading volume in its first 24 hours.

Rollout Details

The expansion went live on September 24, 2026, at approximately 17:52 UTC, encompassing both of the protocol’s core products.

USDai serves as the base token, minted by depositors using existing stablecoins, akin to exchanging dollars for casino chips. sUSDai is the staked version, where holders lock up USDai to receive a token that accrues yield from interest paid on loans issued by the protocol.

Omnichain Fungible Token Standard

The cross-chain transfers utilize the OFT, or Omnichain Fungible Token, standard. This allows tokens issued under the standard to move between blockchains without becoming a different version of themselves upon arrival.

Previously, USDai and sUSDai were exclusively available on EVM-compatible chains, with LayerZero facilitating cross-chain movements within that ecosystem. Solana’s non-EVM architecture necessitated a departure from this established framework.

Verifying Token Addresses

For users wishing to verify the authenticity of their holdings, USD.AI has published the official Solana token addresses: USDai at USDai5XCUzNebYzUk6EuRiFCvnyoyEdj7VSyijYcz2A and sUSDai at sUSDai6Y3GxysDEtA9BVcEFTaog6UZpYUVxJiMhAKYE.

Solana DeFi Integrations

At launch, USD.AI integrated with six Solana DeFi protocols: Jupiter Lend, Kamino, Orca, Loopscale, Exponent, and Mezzanine. These partnerships offer USDai and sUSDai holders opportunities for lending, providing liquidity, and trading in fixed-rate markets.

A significant portion of the bridged sUSDai has already been deployed across Kamino and Jupiter Lend for lending activities, and on Orca, a decentralized exchange, for supplying trading liquidity.

Incentive Programs

For the initial eight weeks, eligible users can earn ALLO points, in addition to other incentives provided by USD.AI.

USD.AI’s Underlying Protocol

The USD.AI protocol operates a credit system that extends loans to infrastructure operators within the AI sector. These loans are secured by GPU hardware, essential for AI model training and inference. The protocol’s loan book currently exceeds $280 million, distributed across 16 facilities. The largest single facility amounts to $128.9 million, backed by 2,304 NVIDIA GB200 GPUs.

The concentration of this large facility within the overall loan book means its performance significantly impacts the total portfolio.

Market Reception and Future Outlook

The initial day’s figures suggest strong demand for USD.AI’s presence on Solana. While the $9.39 million in bridged sUSDai and $372,000 in trading volume are modest compared to the protocol’s $280 million-plus loan book, their rapid arrival indicates significant interest.

For sUSDai holders, this expansion offers enhanced flexibility without altering their underlying exposure. The token’s yield remains tied to the repayment of GPU-secured loans by AI infrastructure operators, regardless of the blockchain it resides on.

Cross-chain operations introduce inherent considerations, including the reliability of the messaging infrastructure supporting the OFT standard. Users engaging with these new routes are advised to confirm official token addresses before transacting to mitigate the risk of encountering counterfeit tokens, a common issue on newly supported networks.
