Curve Finance Review (2025)

Executive Summary

Curve Finance stands as one of DeFi's most important infrastructure protocols, specialising in efficient stablecoin and like-asset swaps. Launched in 2020 by Michael Egorov, Curve has become the go-to platform for low-slippage trades between similar assets, particularly stablecoins and liquid staking tokens (LSTs).

The protocol's unique automated market maker (AMM) algorithm is specifically designed for assets that should trade close to 1:1 ratios, making it significantly more capital efficient than traditional AMMs like Uniswap for these use cases. With over $2 billion in total value locked (TVL) as of 2025, Curve remains a cornerstone of the DeFi ecosystem, facilitating billions of dollars in trading volume each month.

What sets Curve apart is its sophisticated tokenomics system involving CRV tokens and vote-escrowed CRV (veCRV), which creates powerful incentive mechanisms for liquidity providers and governance participants. The protocol has also become central to the "Curve Wars" - a phenomenon in which various DeFi protocols compete to accumulate veCRV voting power, directing CRV emissions to their preferred pools.

Key Achievements and Market Position

Since its launch, Curve has established itself as critical DeFi infrastructure:

• Market Leadership: Dominant position in stablecoin trading with 60%+ market share
• Ecosystem Integration: Core component of major DeFi protocols and strategies
• Innovation Driver: Pioneered ve-tokenomics model adopted by numerous protocols
• Multi-Chain Presence: Deployed on 10+ blockchains and Layer 2 solutions
• Institutional Adoption: Used by major DeFi protocols, DAOs, and institutions

2025 Market Context

In 2025, Curve operates in a mature DeFi landscape where efficiency and capital optimisation are paramount. The protocol has successfully adapted to changing market conditions, including the rise of liquid staking derivatives, the growth of Layer 2 ecosystems, and increasing institutional participation in DeFi.

How Curve Finance Works

StableSwap Algorithm

Curve's core innovation is its StableSwap invariant, a mathematical formula that combines the best aspects of constant product (x*y=k) and constant sum (x+y=k) market makers. This hybrid approach provides:

• Extremely low slippage for trades between similar assets
• High capital efficiency compared to traditional AMMs
• Stable pricing around the 1:1 peg for stablecoins
• Better returns for liquidity providers in stable asset pools

Liquidity Pools and Gauges

Curve operates through various pool types:

• Base Pools: Core stablecoin pools (3Pool: USDC/USDT/DAI)
• Metapools: Pools that pair with base pools for efficiency
• Crypto Pools: For volatile assets with dynamic fees
• Factory Pools: Permissionless pool creation
• Tricrypto Pools: Three-asset volatile pools

Each pool can have an associated gauge that distributes CRV rewards to liquidity providers. Gauge weights are determined by veCRV holders through weekly voting, creating the competitive dynamics known as the "Curve Wars."

veCRV and Governance

The veCRV (vote-escrowed CRV) system is central to Curve's tokenomics:

• Lock CRV tokens for up to 4 years to receive veCRV
• Longer locks provide more veCRV and voting power
• veCRV holders vote on gauge weights and protocol parameters
• Boost LP rewards by up to 2.5x with sufficient veCRV
• Receive 50% of protocol trading fees

Yields & Rewards Structure

Revenue Sources for LPs

Popular Yield Strategies

Conservative Stablecoin Strategy:

• Deposit into 3Pool (USDC/USDT/DAI)
• Stake LP tokens in gauge
• Expected APR: 3-8% (depending on CRV price and incentives)
• Low impermanent loss risk

LST Strategy:

• Provide liquidity to stETH/ETH or similar LST pools
• Earn staking rewards + trading fees + CRV emissions
• Expected APR: 5-12%
• Moderate smart contract and slashing risk

Convex Strategy:

• Deposit Curve LP tokens on Convex Finance
• Automatic veCRV boost without locking CRV
• Earn CRV + CVX tokens
• Simplified management with competitive yields

The Curve Wars: Understanding Protocol Politics

What Are the Curve Wars?

The "Curve Wars" represent one of DeFi's most fascinating governance dynamics, where protocols compete to accumulate veCRV voting power to direct CRV emissions toward their preferred liquidity pools. This competition has created a complex ecosystem of bribes, vote buying, and strategic alliances.

Key Players in the Curve Wars

• Convex Finance (CVX): Controls ~50% of veCRV voting power through user deposits
• Yearn Finance: Significant veCRV holder optimizing yields for users
• Frax Protocol: Accumulated veCRV to support FRAX stablecoin pools
• Redacted Cartel: Specialized in accumulating governance tokens across protocols
• StakeDAO: Offers liquid veCRV through sdveCRV tokens

Bribe Markets and Vote Incentives

The Curve Wars have spawned sophisticated bribe markets where protocols pay veCRV holders to vote for their gauges:

• Votium: Leading bribe marketplace for Convex voters
• Hidden Hand: Bribe platform for various governance tokens
• Typical Bribe Rates: $0.20-$1.00 per $1 of CRV emissions directed
• ROI for Voters: Often 20-50% APR on veCRV holdings through bribes

Impact on Curve Ecosystem

The Curve Wars have had profound effects on the protocol and broader DeFi:

• Increased CRV Demand: Competition drives demand for CRV tokens
• Liquidity Concentration: Votes concentrate liquidity in strategic pools
• Innovation Catalyst: Spawned new tokenomics models across DeFi
• Governance Centralization: Large holders gain disproportionate influence
