DeFi remains prohibitively complex. Users toggle between dozens of protocols, manually compare yields, and manage risk across fragmented interfaces. SperaxOS eliminates this friction.
This approach earned <a target="_blank" rel="noopener noreferrer nofollow" href="https://x.com/SperaxUSD/status/2008785196301312282">Sperax a listing on Anthropic's official MCP Registry</a>, the canonical directory for AI-to-tool integrations used by Claude, ChatGPT, and Cursor. The open-source Sperax Crypto MCP enables any AI assistant to access DeFi data through natural conversation—checking USDs yields, exploring farm APYs, tracking veSPA voting power, and monitoring SPA buybacks. <a target="_blank" rel="noopener noreferrer nofollow" href="https://x.com/SperaxUSD/status/2001211709458198560">Sperax also deployed the first multilingual DeFi agent framework, delivering specialized intelligence in 20+ languages within seconds.</a>
Google Cloud's infrastructure unlocks the next phase of SperaxOS development.
Computational Scale: Processing real-time data across 10+ blockchains requires serious horsepower. Google Cloud enables faster AI responses, richer analytics, and smoother experiences.
Global Reach: Low-latency networking via Google's backbone means users worldwide access SperaxOS instantly, regardless of location or language.
Enterprise Foundation: The same infrastructure powering Coinbase, BNB Chain, and Solana now backs SperaxOS.
"We're seeing real momentum when developers have the tools and resources to just build. Remove the friction, and innovation follows," said Rich Widmann, Head of Web3 Strategy at Google Cloud.
This builds on Sperax's established institutional presence: Alibaba Cloud Marketplace distribution, Anchorage Digital custody, BNB Chain DappBay listings, and SPA available on Coinbase.
The future of DeFi is conversation. Sperax is building the infrastructure to make it reality.
<h3 id="usds-sperax-usd">USDs (Sperax USD)</h3>
A stablecoin yield aggregator on the Arbitrum network
USDs is a <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.investopedia.com/terms/s/stablecoin.asp">stablecoin</a> yield aggregator which generates auto-yield natively. Currently, USDs is live on Arbitrum, the largest Layer-2 Ecosystem of Ethereum. Eventually, Sperax will build a system of interoperability so that USDs will be natively deployed to all major blockchain platforms.
The highlights of this protocol:
<ol>
 <li>Auto-yield - Users holding USDs in their wallets automatically earn organic yield. No staking is required by the end user. Users do not need to spend gas calling the smart contract to claim their yield.</li>
 <li>Layer 2 native — Cheaper transaction fees on Arbitrum make this protocol retail investor-friendly.</li>
 <li>Fully Backed Model - USDs is 100% backed by a diversified basket of whitelisted crypto assets (stablecoins).</li>
</ol>
The rise of decentralized finance (DeFi) has led to a huge increase in the use of stablecoins—cryptocurrencies designed to keep a steady value, usually around $1.
They generally fall into three categories. Fiat-backed stablecoins like USDC, etc. are pegged to traditional currencies and backed by reserves held by centralized issuers. They’re widely used but raise concerns around transparency and control. Crypto-collateralized stablecoins like DAI are backed by on-chain assets. They aim for decentralization but can face scaling limits. Algorithmic stablecoins rely on smart contracts and supply adjustments to maintain their peg without direct collateral. They remain sensitive to market shifts and are still evolving.
Each type balances trade-offs between decentralization, stability, and scalability as the stablecoin ecosystem matures.
USDs has combined the best of existing designs by featuring a 100% backed model like the CDP stablecoins but adds the scalability benefits of fiat backed stablecoins. An on-chain, redemption-based design makes USDs highly scalable, trustless and decentralized.
USDs automates the process of earning yield on stablecoins. Yield is generated organically by sending collateral to audited decentralized finance protocols. 70% of yield generated on collateral is used to pay USDs holders auto-yield. Please refer to <a target="_blank" rel="noopener noreferrer nofollow" href="https://snapshot.box/#/s:speraxdao.eth/proposal/0x401841b87ef3b503e8732eaace2b867faab15b91383e94bad9c90ec61e2540cd">SIP-66</a> for more details.
USDs auto-yield rate is adjustable and depends on the actual yield generated by the collaterals. Any yield generated beyond the max auto-yield rate will be stored in auto-yield reserves. This novel passive income strategy does not require any action from the user. Users can just hold USDs and see wallet balance grow, auto-compounding the yield in the process.
SPA is the value accrual token of the Sperax ecosystem. SPA holders can stake SPA tokens to receive veSPA. veSPA holders are decision makers of the protocol. They will earn staking rewards and manage the protocol revenue via voting power in Sperax governance. Off-chain governance is live on <a target="_blank" rel="noopener noreferrer nofollow" href="https://snapshot.box/#/s:speraxdao.eth/proposals">Snapshot</a>, and community (veSPA holders) can control parameters of USDs protocol, yield strategies, eligible collateral, new product features, etc. On-chain governance will be launched soon making veSPA holders the true owners of the Sperax ecosystem.

<h3 id="sperax-buybacks">Sperax Buybacks</h3>
Buyback contract is designed to decentralize the SPA buyback process while adding a boosting mechanism to continuously grow USDs TVL with protocol revenue (Yield + Fee). This contract allows users to directly purchase USDs with SPA. The available-for-purchase USDs comes from two sources - USDs mint/redeem fees and USDs yield. The contract distributes 70% of the yield to USDs holders and the rest 30% goes to SPA buyback and burn.
Protocol Yield - The yield is collected in multiple tokens through pool fee (USDC, etc.) and farm rewards. This yield is converted to USDs. A portion is sent to buyback contract and remaining to auto-yield reserve. Swap yield tokens to eligible collateral tokens (for minting USDs) using DEXes based on the path of lowest slippage Mint USDs using the collateral tokens Deposit 30% of the yield (USDs received in previous step) that will be used to buyback SPA into the buyback contract and the rest of the USDs is transferred back to the USDs vault’s auto-yield reserve. Yield share percentage is set to 30% currently and can be changed in future through governance.
Protocol Fee - Mint and redemption fee from the USDs protocol is collected in the form of USDs. This component is directly deposited to the Buyback contract.
Buyback SPA - Any users or external wallet can view the USDs balance in the Buyback contract and sell their SPA tokens for USDs.
Burn 2.0 - 30% of the SPA received in step 3 is burnt and remaining 70% is sent to USDs holding wallets. The burn percentage can be changed through governance.
<h4>Example flow of the buyback contract:</h4>
Sperax protocol deposits USDC.e to Stargate strategy (Stargate-LP USDC.e) and stakes LP tokens. Protocol earns STG token.
<ol>
 <li>Sell STG tokens for USDC.e</li>
 <li>Mint USDs from USDC.e</li>
 <li>Transfer USDs to the Buyback contract</li>
 <li>Deposit USDs Mint and Redemption Fees directly into the Buyback contract as and when they are collected</li>
 <li>Users can view the amount of USDs left in the contract.</li>
 <li>USDs is bought by the users using their SPA and contract receives SPA against the USDs.</li>
</ol>
