Complete guide to USDs, the auto-yield stablecoin on Arbitrum by Sperax. Covers minting, redeeming, yield mechanics, collateral strategies, and integration patterns. Use when your agent needs to explain USDs, help users mint/redeem, or answer questions about auto-rebasing stablecoins.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# USDs — Auto-Yield Stablecoin Guide USDs is an **auto-yield stablecoin** on Arbitrum One built by [Sperax](https://chat.sperax.io). Holding USDs in your wallet automatically earns yield — no staking, no claiming, no gas fees for rewards. ## How USDs Works ### The Basics - **1 USDs = 1 USD** (soft peg maintained by mint/redeem arbitrage) - **Chain**: Arbitrum One - **Collateral**: 100% backed by USDC, USDC.e, and USDT - **Yield**: Balances grow automatically via rebasing — just hold it ### Mint & Redeem **Minting**: Deposit 1 USD of collateral (USDC, USDC.e, or USDT) → receive 1 USDs (minus a small mint fee). **Redeeming**: Burn USDs → receive your chosen collateral back (minus a small redemption fee). The mint/redeem mechanism creates a natural arbitrage loop that keeps USDs pegged to $1: - If USDs > $1 → arbitrageurs mint USDs (sell high) - If USDs < $1 → arbitrageurs redeem USDs (buy low) ### Auto-Yield Mechanics USDs uses a **rebase** model. Instead of distributing reward tokens, the protocol increases everyone's USDs balance proportionally. **Yield source**: Collateral (USDC, USDT) is deployed to battle-tested DeFi protocols: - Aave V3 - Compound V3 - Fluid …

How to install
mdr add nirholas/three.ws/sperax-usds-guide@sha256:0d826446416b25d3The line at the top of this page pins the label git:20260501.87cefc9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
