Michael Egorov published the StableSwap paper describing an automated market maker (AMM) optimized for assets that should trade near the same price (like USD stablecoins). This design targeted lower slippage (price impact) and lower fees than general-purpose AMMs for stablecoin trades. The paper set the technical foundation for Curve’s later stablecoin liquidity pools.
Curve launched in early January 2020 as a decentralized exchange focused on efficient swapping between stablecoins and other “pegged” assets. Its early focus on stablecoin liquidity made it a key building block for other DeFi apps that needed deep, low-slippage USD liquidity. This launch created the base infrastructure that later token incentives would amplify.
Yearn introduced the YFI governance token and launched liquidity mining programs, including rewards for liquidity providers in the Curve “y” pool (often called yPool). This helped connect Curve’s stablecoin liquidity with yield strategies that moved funds across protocols to chase better returns. The integration highlighted how stablecoin pools could become “money legos” inside larger DeFi systems.
Curve’s CRV token and DAO (decentralized governance) contracts were deployed on-chain in a surprise event: an anonymous community member deployed contracts using code Curve had made public. Curve verified the deployment and treated it as the official launch. This event began Curve’s transition from a single team-run protocol toward community governance.
After the CRV launch, Curve began distributing CRV to liquidity providers through “liquidity mining,” meaning users earned tokens for depositing assets into pools. This turned stablecoin liquidity into an actively incentivized market and quickly increased deposits. The new incentives helped Curve’s stablecoin pools become deeper and more competitive as trading venues.
Curve’s total value locked (TVL)—the value of assets deposited into the protocol—reached $1 billion in mid-August 2020. The jump showed how strongly token incentives and stablecoin demand could concentrate liquidity into a specialized AMM. This scale mattered because deeper pools generally reduce slippage and support larger stablecoin trades.
Curve launched the 3pool, a large stablecoin pool containing DAI, USDC, and USDT, designed to be gas-optimized and serve as a “base pool” for other pools. The base-pool idea supported metapools, where a new stablecoin can be paired against 3pool’s LP token to tap into deeper shared liquidity. This structure became central to how stablecoins bootstrapped liquidity on Curve.
Curve’s DAO governance relied on veCRV (vote-escrowed CRV), obtained by locking CRV for up to four years. Longer locks provided more voting power, and voting power decayed as unlock time approached, pushing governance toward longer-term participants. This model linked stablecoin liquidity incentives to governance decisions about which pools should receive CRV emissions.
Curve’s system of liquidity gauges and gauge-weight voting let veCRV holders decide how new CRV rewards were distributed across pools. In practice, this meant protocols launching stablecoins could compete for votes to attract liquidity, since higher rewards could draw in more deposits. This set the stage for stablecoin liquidity becoming a strategic resource governed by token voting.
Curve paused ("killed") a newly launched pool associated with Yearn’s yVault2 after discovering a vulnerability. Curve stated that funds were safe and would be returned to liquidity providers automatically. The incident showed that even widely used stablecoin liquidity infrastructure could face smart-contract risk, and that emergency controls could be used to protect LPs.
Curve announced a version 2 of its pool factory, aimed at making it easier for others to deploy new pools under defined conditions (such as liquidity and audit expectations for UI inclusion). This mattered for stablecoin liquidity because it supported faster experimentation and listings, while still signaling standards for broader visibility. The factory approach helped Curve scale beyond a small set of core pools.
Curve released Curve V2 in June 2021, adapting its design to support trades between assets that are not tightly pegged (for example, mixed crypto/stablecoin pools). While stablecoin liquidity remained central, V2 broadened Curve’s role and helped keep the protocol relevant as DeFi markets diversified. This period also reinforced Curve’s position as a core liquidity layer whose incentives affected where stablecoins and related assets traded.
