Understanding USDFI Pools

Providing liquidity carries certain risks. In this section, the different pools within the USDFI ecosystem will be reviewed, in order to assist users in finding a pool that aligns with their risk tolerance. The risks associated with being a liquidity provider on USDFI will also be explained.
At present, there are several USDFI pools available, with new pools being added on a regular basis subject to whitelisting. It is important to note that when providing liquidity to a pool, one is exposed to both tokens within the pool regardless of the tokens deposited, therefore it is crucial to choose a pool with coins that a user is comfortable holding.

Revisiting the concept of liquidity pools

Liquidity pools are pools of tokens that exist within smart contracts. They can be a complex concept to understand, particularly for those new to Ethereum or DeFi. As an example, if one were to create a pool consisting of both USDT and USDC, where 1 USDT is equal to 1 USDC, and the pool contains 1,000 tokens of each (1,000 USDT and 1,000 USDC), If a trader exchanges 100 USDT for 100 USDC, the pool would then contain 1,100 USDT and 900 USDC, causing the price of USDC to slightly decrease in order to encourage another trader to exchange USDC for USDT, thus balancing the pool again.


It is important to understand the role of the different pools in USDFI and how liquidity providers earn money. USDFI earns revenue from trading fees. When a user exchanges tokens through the USDFI website, 1inch, Paraswap, or another decentralized exchange aggregator, a small fee is earned and distributed as a bribe to veSTABLE holders, split evenly among all holders. APY may be higher on days with high volume and volatility; and may be low on some days.


Swap fees on USDFI for sAMM are generally 0.04% and for vAMM 0.30%, which is considered to be one of the most efficient ways to exchange stablecoins and other tokens on the any EVM blockchain. Deposit and withdrawal fees are 0% in the protocol. There may be network fees.
