## What Is Curve Finance?

Curve Finance is a [decentralized](https://coinmarketcap.com/alexandria/glossary/decentralized) [liquidity pool](https://coinmarketcap.com/alexandria/glossary/liquidity-pool) for [stablecoin](https://coinmarketcap.com/alexandria/glossary/stablecoin) trading. Instead of an [order book](https://coinmarketcap.com/alexandria/glossary/order-book), it uses an [AMM](https://coinmarketcap.com/alexandria/glossary/automated-market-maker-amm) (automated market maker) model to match [liquidity](https://coinmarketcap.com/alexandria/glossary/liquidity). As a decentralized and permissionless protocol, anyone can [provide](https://coinmarketcap.com/alexandria/glossary/liquidity-provider-tokens-lp-tokens) liquidity to one or more of the [liquidity pools](https://coinmarketcap.com/alexandria/glossary/liquidity-pool). The constant product formula of the AMM ensures maximum efficiency while incurring a minimum of [slippage](https://coinmarketcap.com/alexandria/glossary/slippage) for traders. 

The Curve pools are [smart contracts](https://coinmarketcap.com/alexandria/glossary/smart-contract) implementing the StableSwap invariant and enabling the exchange of two or more tokens. Token [swaps](https://coinmarketcap.com/alexandria/glossary/token-swap) can be performed between paired stablecoins (Plain Pools) or between [wrapped](https://coinmarketcap.com/alexandria/article/what-is-wrapped-ethereum-weth) tokens, with the underlying collateral lent out on another protocol (Lending Pools). Finally, Metapools pair stablecoins against LP-tokens from another pool.

The protocol is available multi-chain — on [Ethereum](https://coinmarketcap.com/currencies/ethereum/), [Arbitrum](https://coinmarketcap.com/alexandria/article/what-is-arbitrum-the-ultimate-guide-to-the-arbitrum-ecosystem), [Aurora](https://coinmarketcap.com/currencies/aurora-near/), [Avalanche](https://coinmarketcap.com/currencies/avalanche/), [Fantom](https://coinmarketcap.com/currencies/fantom/), [Harmony](https://coinmarketcap.com/currencies/harmony/), [Optimism](https://coinmarketcap.com/alexandria/article/what-is-optimism-the-ultimate-guide-to-the-optimism-ecosystem), [Polygon](https://coinmarketcap.com/currencies/polygon/), [xDai](https://coinmarketcap.com/currencies/xdai/) and [Moonbeam](https://coinmarketcap.com/currencies/moonbeam/). Users typically have to [bridge](https://coinmarketcap.com/alexandria/glossary/bridges) funds from Ethereum to these chains to use the Curve protocol. Due to its systemic importance for [decentralized finance](https://coinmarketcap.com/alexandria/glossary/defi) (DeFi), the protocol has attracted several other protocols fighting over its [governance](https://coinmarketcap.com/alexandria/glossary/governance) in the so-called [Curve Wars](https://coinmarketcap.com/alexandria/article/curve-wars-and-the-emergency-dao).
