StableVault can be found on the StableVault page of our website.
StableVault uses code that has been forked from Saddle Finance, which has been audited. However, we still recommend using the protocol with caution as any new code has not been audited. You can review our code on the Snowball GitHub.
No, you can deposit any combination of tokens into StableVault. This is possible because the tokens in the pool are all pegged to the U.S. dollar. To keep the balance of the pool stable, we give incentives to anyone who deposits a token that has a lower supply in the pool.
If you deposit a token that is high in supply, relative to other tokens in the pool, you will pay a small premium for depositing. Similarly, if you deposit a token with a low supply, relative to the other tokens in the pool, you will be given a discount.
For example, if there are 300 USDT, 500 BUSD, and 700 DAI in the s3D pool, you will need to pay a fee to deposit DAI and you will be given a reward to deposit USDT. This works the same for withdrawing from the pool. Given the above example, you would pay a fee to withdraw in USDT and be rewarded for withdrawing in DAI.
USDT and DAI can be found on most Avalanche exchanges or centralized exchanges. BUSD is harder to find since there is not currently a large supply on Avalanche. To get BUSD you will either need to buy it on a centralized exchange or use the Ethereum-Avalanche Bridge to send your tokens to Avalanche.
Most decentralized exchanges are modeled after Uniswap version 2. They are excellent models for swapping most cryptocurrencies; however, they are not great for swapping stablecoins or other value-pegged assets. The reason is because the model they use allows for lots of slippage, or price variance, on the tokens.
If a stablecoin pool undergoes a large transaction in this traditional model, then the two coins may be taken off peg. One may trade slightly lower than $1, perhaps around $0.95, while the other may trade slightly higher, perhaps at $1.05. With StableVault the coins would still be relatively close to their $1 peg, perhaps closer to $0.99 and $1.01.
