Rubic Integrates Curve Finance: Stable Pools & Better Rates for Stables
We are constantly looking for opportunities to provide our users with better rates, and here’s the new one: Rubic has added Curve’s pools to its ecosystem. This integration enriches the Rubic platform with better rates for stablecoins and stabilizes pools and slippage.
What is Curve?
Curve is an exchange liquidity pool on Ethereum. Curve is designed for extremely efficient, low-risk stablecoin trading and supplemental fee income for liquidity providers, without additional costs.
Since stablecoins have become an inherent part of the crypto world, there’s now a huge variety of them (DAI, TUSD, sUSD, bUSD, USDC, and others), and, therefore, a need to swap those.
Unlike Centralized Exchanges that tend to have rather high fees, Curve achieved efficient stablecoin trading by implementing StableSwap, which has significantly lower slippage for stablecoin swaps.
StableSwap
StableSwap processes as a mechanism that creates cross-markets for stablecoins in a way which could be called “Uniswap with leverage”. It is a fully autonomous market-maker for stablecoins with very minimal price slippage.
Curve: Between Blockchains
Curve exists across several chains. Curve’s primary chain will always be Ethereum, but other sidechains have more advantages including speed and cost. Curve operates between 12 significant chains such as Ethereum, Polygon, Arbitrum, Avalanche, Celo, Kava, Fantom, Gnosis, Moonbeam, Optimism, and Harmony.
Rubic x Curve:
With this integration, Rubic acquires better rates for stablecoin trading and provides more stable pools and slippage for cross-chain trades.
Curve is integrated as an additional provider for 8 blockchains on Rubic — Ethereum, Polygon, Avalanche, Arbitrum, Fantom, Celo, Optimism, and Gnosis.
Swap fees by Curve are typically around 0.04% which is thought to be the most efficient when exchanging stablecoins on Ethereum.
Curve Numbers
Let’s explore Curve data and statistics.
The most demanded blockchain on Curve is, without a doubt, the Ethereum network. The number of active Curve users on Ethereum is 82,893. Polygon network is quite in-demand as well, with 56,199 active users on Curve. Curve’s Total Deposit number is $3,498,150,939, and their Daily Volume sums up to $197,490,234.

Understanding Curve Pools
There are currently numerous Curve pools, with new pools added all the time.
If you are new to Ethereum or DeFi, liquidity pools are a seemingly complicated concept to understand.
Liquidity pools are pools of tokens that sit in smart contracts. If you were to create a pool of DAI and USDC where 1 DAI = 1 USDC, you would have the same amount of tokens if 1,000 tokens (1,000 DAI and 1,000 USDC) were in the pool.
If trader 1 comes and exchanges 100 DAI for 100 USDC, you would then have 1,100 DAI and 900 USDC in the pool, so the price would tilt slightly lower for USDC to encourage another trader to exchange USDC for DAI and average the pool back.
Curve Pools:
- Plain v1 Pools
A plain pool is the simplest and earliest implementation of Curve, where all assets in the pool are ordinary ERC-20 tokens pegged to the same price.
One of the largest is TriPool, holding only the three biggest stable coins (USDC/USDT/DAI). It’s a non-lending gas optimized pool similar to the sUSD one.
- Lending Pools
A small number of v1 pools are lending pools, which means you earn interest from lending as well as trading fees.
The Compound pool is the first and oldest. The © you see above stands for cTokens which are Compound native tokens. This means your stablecoins in the Compound pool would only be lent on the Compound protocol.
- MetaPools
MetaPools allow for one token to seemingly trade with another underlying base pool.
About Rubic
Rubic is a Cross-Chain Tech Aggregator for users and dApps.
Our vision is that Rubic’s new umbrella SDK will aggregate the best Web3 cross-chain tech — from signals and oracles, to tokens and NFT bridges, in ready-made templates for DEXs, Lending/Farms, and more. This will help developers easily make their Web3 dApps cross-chain, regardless of what their function is.
Right now, Rubic aggregates 26 major blockchains, 90+ DEXs and bridges, and enables swapping of 15,500+ assets with the best rates, highest liquidity, and transaction speeds — in one click. Users can do it on https://app.rubic.exchange, but we also provide tools for dApps to enable cross-chain swaps (https://tools.rubic.exchange).
On top of that, Rubic’s app and our cross-chain widget provide fiat on-ramp services, making crypto easy to access and buy.
