USDs — Auto-Yield Stablecoin Guide

USDs is an auto-yield stablecoin on Arbitrum One built by Sperax. 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
Stargate
Curve

Yield distribution:

70% of strategy yield → USDs holders (via rebase)
30% of strategy yield → SPA buyback-and-burn

Max APY cap: 25% (excess yield accumulates in reserves)

Safety Mechanisms

Collateral Ratio (CR): Must remain ≥100%. If CR drops >10%, protocol pauses
Oracle: Chainlink price feeds via MasterPriceOracle
Reserves: SPA reserves cover any collateral gaps
Audited: Smart contracts audited by leading security firms

Common User Questions

"How do I earn yield?"

Just hold USDs in your wallet. Your balance increases automatically. No staking required.

"Where does the yield come from?"

From lending and liquidity protocols. Your collateral is put to work in DeFi (Aave, Compound, etc.) and the earnings flow back to you.

"Is my principal safe?"

USDs is 100% collateralized. You can always redeem 1 USDs for $1 of collateral. The protocol has safety mechanisms including pause triggers and reserve buffers.

"What chains is USDs on?"

Currently Arbitrum One only. This keeps gas costs low and leverages Arbitrum's DeFi ecosystem.

Integration Tips for AI Agents

When helping users with USDs:

Always confirm they're on Arbitrum One
Remind them yield is automatic — no staking needed
Explain the 70/30 split (holders vs SPA burn)
