USDCoin (USDC) トケノミクス

USDC (USD Coin) is a regulated, fully-backed stablecoin pegged 1:1 to the US Dollar (USD). Its token economics are fundamentally different from those of utility or governance tokens, as its primary function is to serve as a stable medium of exchange. The mechanisms governing USDC are centralized and controlled by its issuer, Circle.

Issuance Mechanism

The issuance mechanism for USDC is dynamic and elastic, meaning the supply expands and contracts based on market demand for the token.

• Peg and Collateralization: USDC is pegged 1:1 to the US Dollar and is collateralized by corresponding USD held in cash and cash equivalents. This backing is subject to monthly public reserve attestations conducted by Deloitte.
• Minting (Issuance): New USDC tokens are minted by Circle when users with a Circle Mint account deposit fiat currency (USD) through a wire or bank transfer on a 1:1 basis. This process is handled exclusively by Circle.
• Burning (Redemption): Conversely, USDC tokens are redeemed (burned) when users with a Circle Mint account send USDC to a designated deposit address in exchange for fiat currency on a 1:1 basis. This redemption process is also handled by Circle.
• Elastic Supply: The supply of USDC is elastic, expanding when demand for the token increases (more minting) and contracting when demand decreases (more burning).

Allocation Mechanism

USDC does not have a traditional token allocation mechanism like those used for governance tokens (e.g., allocations for team, investors, or community).

• No Public Allocation Disclosure: A commercially reasonable search found no disclosures from the project team regarding the allocation of USDC to any party, including the project team, or for the compensation of employees, directors, or advisors.
• Centralized Control: Circle handles all aspects of USDC smart contract development, issuance, and redemption, ensuring the token is fully backed by reserve assets.

Usage and Incentive Mechanism

The primary use of USDC is as a stable medium of exchange on blockchains, mitigating price risk for tokenholders.

• Primary Utility: USDC is a tokenized representation of the USD, natively supported on 16 networks and available on over 50 networks in total (primarily as an ERC-20 token on Ethereum). It allows tokenholders to transact across borders, with fees and settlement times determined by the underlying network.
• Governance: As of December 8, 2024, there is no community or tokenholder-based governance mechanism for USDC or Circle. Changes to USDC cannot be implemented without the consent of Circle.
• Incentives (Directly from Circle): Based on a commercially reasonable search, users cannot earn fees, additional tokens, or any form of compensation directly by interacting with or using USDC via Circle.
  • Credits Program: Circle does offer a Credits Program that provides monetary discounts for various Web3 Services products, such as the Smart Contract Platform and Gas Station.
  • Grants: Circle also runs a USDC Grant Program for early-stage projects leveraging USDC, offering support and grants paid in USDC (ranging from $5,000 to $100,000). Applications for this program are set to re-open in 2025.
• Incentives (Third-Party): Some third-party platforms, such as Coinbase, have offered rewards programs for holding USDC. For example, Coinbase previously offered USDC tokenholders a 35% APY (paid in USDC monthly), funded by Coinbase's own funds.

Locking Mechanism and Unlocking Time

USDC, as a stablecoin, does not feature a native locking or vesting mechanism for its tokenholders.

• No Native Locking: There is no protocol-level mechanism requiring tokenholders to lock USDC for a specific duration to earn rewards or participate in governance.
• Centralized Control Functions: While there is no user-facing locking mechanism, the USDC smart contract includes centralized control functions that allow Circle to manage the token supply and enforce compliance:
  • The ERC-20 USDC token contract is an upgradeable proxy contract.
  • Functions exist that allow the address with the "minter" role to burn USDC they hold.
  • If a USDC user is found to violate the Acceptable Use Policy, they are subject to corrective actions, including blocking or withholding a transaction or suspending, restricting, or terminating their use of the services.

Information regarding a specific unlocking time or vesting schedule for USDC tokens is not applicable, as the token is designed for immediate liquidity and transferability, with its supply managed dynamically through minting and burning by Circle.
