โทเคโนมิกส์ Curve (CRV)

Overview

Curve DAO Token (CRV) is the native governance and incentive token of Curve Finance, a leading decentralized exchange (DEX) optimized for stablecoin and like-asset swaps. The tokenomics of CRV are designed to incentivize long-term participation, align stakeholder interests, and ensure robust protocol governance.

Issuance Mechanism

• Minting & Distribution:
  CRV tokens are minted and distributed primarily as rewards to liquidity providers (LPs) on Curve Finance. The issuance rate and allocation to different pools are determined by the Curve DAO through a system of "gauges" and on-chain voting.
• Smart Contracts:
  • The Minter contract is responsible for CRV issuance.
  • The GaugeController contract manages the allocation of CRV emissions to various liquidity pools based on veCRV holder votes.
• Governance Control:
  The Curve DAO, governed by veCRV holders, can adjust emission rates, add or remove gauges, and change protocol parameters.

Allocation Mechanism

Note: The above allocations are based on available documentation and may overlap in categories. The majority of CRV is distributed to liquidity providers over time via ongoing emissions.

Usage and Incentive Mechanism

• Governance:
  CRV can be locked to obtain veCRV (vote-escrowed CRV), which grants voting power in the DAO. Only veCRV holders can vote on proposals, gauge weights, and protocol upgrades.
• Liquidity Mining:
  LPs earn CRV rewards for providing liquidity to Curve pools. The amount of CRV earned depends on the pool's gauge weight and the LP's veCRV balance (boosting).
• Fee Sharing:
  veCRV holders receive 50% of all trading fees generated by the protocol, distributed as 3CRV (a stablecoin LP token).
• Boosting:
  By locking CRV for veCRV, users can boost their CRV rewards up to 2.5x when providing liquidity.
• Bribing & Metagovernance:
  Protocols and DAOs may offer incentives ("bribes") to veCRV holders to vote for their preferred gauges, creating a secondary market for governance influence.

Locking Mechanism

• veCRV (Vote-Escrowed CRV):
  • Users lock CRV for a period between 1 week and 4 years to receive veCRV.
  • The longer the lock, the more veCRV is received (max boost at 4 years).
  • veCRV is non-transferable and decays linearly as the unlock date approaches.
• Governance Weight:
  Voting power is both amount- and time-weighted:
  weight = amount_locked * (lock_time / max_lock_time)
• Locking Participation:
  As of late 2022, 53.8% of CRV's circulating supply was locked, with an average lock duration of 3.56 years—demonstrating strong long-term commitment.

Unlocking Time

• Lock Duration:
  • Minimum: 1 week
  • Maximum: 4 years
• Unlocking:
  • After the lock period, users can withdraw their CRV.
  • No early unlocking is permitted.
• Vesting Schedules:
  • Team and employee allocations are subject to linear vesting (2-4 years).
  • Investor allocations are subject to a 2-year linear vesting.

Additional Insights

• Governance Structure:
  Curve DAO uses Aragon-based smart contracts with time-weighted voting, ensuring that long-term participants have greater influence.
• Security & Emergency Controls:
  The "Curve Emergency DAO" can disable pool functions in emergencies, requiring a multi-sig vote.
• Ecosystem Impact:
  The veCRV model has inspired similar tokenomics in other DeFi protocols, emphasizing long-term alignment and active governance.

Summary

Curve DAO Token's tokenomics are built around incentivizing long-term participation, robust governance, and deep liquidity. The vote-escrowed (veCRV) model is central, rewarding users for locking tokens and actively participating in the protocol's future. The combination of ongoing emissions, fee sharing, and governance power has made CRV a foundational asset in the DeFi ecosystem.
