Angle Protocol is running a private beta before the official launch of USDA, its new U.S. Dollar stablecoin. The Private Beta begins on April 8th and ends on April 16th. Beta testers will be rewarded with OP (Optimism) tokens for their participation!

What’s USDA?

USDA is Angle Protocol’s new U.S. Dollar stablecoin.

It’s the most complete USD stablecoin offering an unmatched combination of reliability, yield, liquidity and transparency.

USDA is decentralized and over-collateralized. It’s available cross-chain with the same liquidity as USDC while incorporating a native savings solution offering the best of TradFi and DeFi risk-adjusted yields, along with a borrowing & leverage feature. To ensure unwavering stability, USDA's design incorporates advanced anti-depeg mechanisms. Moreover, everyone is able to verify USDA’s collateral reserves 24/7 thanks to its transparent real-time balance sheet.

With USDA and EURA (prev. agEUR) trading at competitive rate, Angle will give individuals and institutions access to the foremost onchain foreign exchange (forex) market!

How are rewards distributed?

Beta testers will share a prize pool of $50,000 in OP (Optimism) tokens!

OP tokens will be distributed to participants who have minted USDA from USDC on Ethereum, bridged their USDA on Optimism and deposited their USDA into Angle savings solution — stUSD — on the Optimism network.

Participants will receive daily OP rewards, determined by their stUSD balance on Optimism.

No need to stake stUSD to earn OP tokens. Owning stUSD on the Optimism network automatically qualifies users for rewards.

There is no minimum deposit required to participate in the private beta. However, the larger the stUSD balance on Optimism, the more rewards testers will receive.

stUSD is the yield-bearing token of Angle Dollar savings product. By owning stUSD during the private beta, testers will also earn a yield on the USDA they deposited!

That's correct. OP tokens plus a Dollar yield!

How to claim rewards?

The OP reward mechanism will begin on April 9th, one days after the start of the private beta. During the first day of the beta (as well as all other days of the beta), users will receive a Dollar yield for holding stUSD.

From April 9th to April 16th, $6,250 in OP tokens will be distributed each day among beta testers (for a total of $6,250*8 days = $50k).

Rewards will be distributed via Merkl, Angle Labs reward hub.

Each day of the private beta, stUSD holders on Optimism will be able to claim their OP rewards by connecting their wallets to Merkl, clicking on the “Claim” button and confirming the transaction in their wallet.

Participants will have 1 year to claim theirs rewards (April 16th, 2025).

How to participate?

1. Make sure you hold any of the tokens mentioned earlier or get your address whitelisted by sharing your Ethereum address on X or Discord.
2. Go on the Angle app at https://beta.angle.money.
3. Go in the 'Buy' section of the App and swap some USDC to USDA on the Ethereum network. You can also swap USDC to USDA directly on Odos and 1inch.

   Please note that you can swap various tokens for USDA on the Ethereum network (e.g., wETH, USDT, ...). However, swaps from USDC to USDA incur no fees (except gas fees).

   

4. Navigate to the 'Bridge' section of the Angle app and bridge your freshly minted USDA from the Ethereum network to the Optimism network.

   

5. Go in the 'Earn Dollars' section of the app, choose the Optimism network, and deposit your USDA. You will receive stUSD tokens in your wallets in exchange.

   Please note that stUSD is a yield-bearing token. Its value increase over time. 1 USDA is not necessarily equal to 1 stUSD.

   

   What are the risks?

   As with any DeFi product, zero risk doesn't exist.

   Although smart contracts are undergoing regular audits, a vulnerability in stUSD and USDA’s smart contracts could leave the funds of the protocol to be hacked.

   Angle also depends on oracles to assess the price of the assets it has in its reserves. The failure of an oracle may lure the protocol into giving away its assets at a deflated value thus leaving the protocol under-collateralized.

   As with oracles, some of the collateral assets of USDA are controlled by centralized entities which represent a counterparty risk.
