Choosing a Curve Pool
As you should know, providing liquidity doesn’t come without its fair share of risks so in this article, we review the different Curve pools to help you find one that matches your risk tolerance while explaining the risks involved with being a liquidity provider on Curve.
There are currently seven pools on Curve, the first five are stable coin pools and the last two are tokenised Bitcoin pools (Bitcoin on Ethereum).
It’s important to understand that when you provide liquidity to a pool, no matter what coin you deposit, you essentially gain exposure to all the coins in the pool which means you want to find a pool with coins you are comfortable holding.

All Curve liquidity gauges receive CRV based on how much the DAO allocates to it.


To understand what the different pools do, it’s also important to understand how Curve makes money for liquidity providers. Curve interests come from trading fees. Every time someone uses Curve to exchange stable coins, through the Curve website, 1inch, Paraswap or another dex aggregator, a small fee is distributed to liquidity providers. This is why the more volume on Curve, the higher the APY are.
Some pools (Compound, PAX, Y, BUSD) also earn interests from lending protocols. Behind the scenes, those four pools also use lending protocols (like Compound or AAVE) to help generate more interests for liquidity providers. Whilst it means those pools can be better performers when lending rates are high, it’s also worth noting it also add more layers of risks.
So all pools earn interest from trading fees, some pools also earn interest from lending and there are also some pools with incentives. You can also receive CRV when you provide liquidity on Curve Finance. Each liquidity gauge receives a different amount of CRV based on how much the DAO allocates to it.

Lending Pools

The four first pools are the lending ones which means as explained above, you earn interest from lending as well as trading fees.
The Compound pool is the first and oldest. The (c) you see above stands for cTokens which are Compound native tokens. This means your stable coins in the Compound pool would only be lent on the Compound protocol.
The other pools are yPools which are tokens for iEarn. iEarn is a yield aggregator. You might think that Compound doesn’t always have the best lending rates and you would be right and thus the yToken balances automatically rebalance your stable coin to the protocol(s) with the better rates (Compound, Aave and dYdX). It’s free and non-custodial (as is Curve) but it is also why the yPools are considered more risky as you use a series of protocols that could themselves have critical vulnerabilities.
A newer generation of pools like AAVE and sAAVE also lend on AAVE v2. Lending pools are generally more expensive to interact with.
In those pools, your risks are as follow:
  • Smart contract issues with lending protocols
  • Smart contract issues with Curve
  • Smart contract issues with iEarn
  • Systemic issues with the stable coins in those pools
Whilst it’s important to not underplay risks associated with providing liquidity on Curve or DeFi in general, it’s worth noting that all the protocols mentioned above have existed for several months (or more for Compound or iEarn) meaning they have been extensively time tested and exploit attempts have been numerous.

Plain Pools

There is also the TriPool which is the biggest Curve pool as it holds only the three biggest stable coins (USDC/USDT/DAI). It's a non-lending gas optimised pool similar to the sUSD one.
sUSD is a newer pool on Curve, it doesn’t have any lending but is still one of the best performers because of its incentives which come from a partnership between Curve and Synthetix.
When you lend on this pool, you can stake your LP (liquidity provider) tokens and earn SNX which makes it an attractive proposition. It’s worth noting that sUSD is Synthetix stable coin which is a synthetic product which means it may not be backed 1:1 like other stable coins are supposedly meant to be.
In this pool, your risks are as follow:
  • Smart contract issues with Curve
  • Systemic issues with the stable coins in those pools
  • Systemic issues with Synthetix (for sUSD)
As you can see, risks are different which might make this pool a better choice for you depending on what your concerns in the cryptosphere are.

Bitcoin Pools

Recently introduced to Curve, it is now possible to participate in two tokenised Bitcoin pools.
The first one pool has renBTC and wBTC, two fully backed versions of Bitcoin on Ethereum. renBTC is fully decentralised but has only existed for a few weeks and wBTC has a lower level of decentralisation but has been around for a bit longer.
This pool receives trading fees only and is likely to have a small APY as Bitcoin on Ethereum is only getting started and thus not generating large volumes yet.
The second one is the sBTC pool. Find a guide on providing liquidity to this pool by clicking here. On top of having wBTC and renBTC, it has sBTC which is a synthetic version of Bitcoin on the Ethereum chain. It is the Bitcoin pool offering the best returns but it also has more risks.
The third one is the hBTC pool which holds wBTC as well as hBTC.
In those pools, your risks are as follow:
  • Smart contract issues with Curve
  • Systemic issues with wBTC or renBTC (ren pool)
  • Systemic issues with hBTC or wBTC (hBTC pool)
  • Systemic issues with Synthetix (sBTC pool only)
