Token Details

Coin Distribution

"Nearly all of the USDC supply on Tron is concentrated in the top 10 addresses."

Tech

  • Whitepaper can be found [insert here].
  • Code can be viewed [insert here].

Implementations

"“We anticipate that in the coming months USDC will become available on Avalanche, Celo, Flow, Hedera, Kava, Nervos, Polkadot, Stacks, Tezos, and Tron,” according to a draft announcement from USDC administrator CENTRE obtained by CoinDesk."

How it works

"These fiat-backed stablecoins come with the implicit promise that they can always be redeemed for a dollar in a bank. Both are tied to huge exchanges (Coinbase and Binance) and have a smooth arbitrage loop for when they’re trading below a dollar. When above a dollar, investors are incentivized to deposit from their bank account, mint more USDC or BUSD, and sell into the market."

Upgrades

"Centre announced a multi-chain framework for supporting USDC on non-Ethereum blockchains. Algorand will be the first to receive stablecoins powered by USDC."

"The "USDC 2.0" update will allow services that offer USDC support to pay transaction fees (gas) for their users."

Interoperability

Other Details

Privacy Method

Compliance

  • USD Coin is issued by regulated and licensed financial institutions that maintain full reserves of the equivalent fiat currency. CENTRE notes that issuers are required to regularly report their USD reserve holdings, and Grant Thornton LLP issues reports on those holdings every month.
  • Circle confirmed freezing $100K in USDC at law enforcement’s request (9-7-2020). This appears to be the first time an address was blacklisted, as noted in an earlier report by The Block.
  • From Bitcoin.com (25-5-2021):

"USDC is late producing its attestation documents, according to data taken from its own transparency website. The attestations, that are scheduled to be produced monthly have stopped, with the last one dealing with February’s funds released last April 27, a considerable delay from its normal issuance date. To make things worse, the crypto asset has experienced explosive growth since February. Its market cap has gone from 9 billion USDC on February 28 to 20 Billion USDC at the time of writing, more than doubling its issuance in just a few months according to numbers taken from Coingecko."

Looking at the transparency page, weirdly enough a new report on March was released the 24th, 1 day before the above article of Bitcoin.com. The report concluded that "The US Dollars held in custody accounts are at least equal to or greater than the USDC tokens outstanding". This would show that either Bitcoin.com had been slacking, or the report is dated from the 24th but was released later. Either way, USDC being late on reports is still something to keep track of.

Projects that use or built on it

"Is working with the U.S. government to bypass Nicolás Maduro and support the Bolivarian Republic of Venezuela led by Juan Guaidó.

"Visa has announced a partnership with Circle Internet Financial and will be integrating its USDC stablecoin."

Competition

  • $-pegged stablecoins in general, but centralized ones more specifically. Other well known examples of centralized stablecoins are issued by Tether, Paxos and Binance. The most well known decentralized stablecoin alternative is DAI, which has been collateralized partly by USDC since 2020. It has reached around 40% of the collateral (6-2021). Some therefore call DAI a semi-decentralized stablecoin.

Pros and Cons

Pros

  • Circle and Coinbase are well known and respected companies in the space. People therefore trust it to be solvent.

Cons

"USDC is a stablecoin tied to the US dollar created by Circle and Coinbase. It is 100% centralized and, like WBTC, has a pause function built right into its smart contract that would allow Circle or Coinbase to freeze anyone's USDC assets at any time.

If this function was called to freeze USDC deposited into Sets as collateral, the expectation is that any Sets collateralized by USDC would potentially become worthless (depending on if the assets were unfrozen at a later date)."

Team, Funding, Partnerships, etc.

Team

Funding

Partners

"Is working with the U.S. government to bypass Nicolás Maduro and support the Bolivarian Republic of Venezuela led by Juan Guaidó. CEO Jeremy Allaire told CoinDesk this was his company’s first government partnership. According to the company’s blog post, the Treasury Department and the Federal Reserve deposit funds seized by the U.S. into a bank account in the U.S. tied to the Guaidó government, which converts the funds into USDC that Circle then sends to Airtm."

"Visa has announced a partnership with Circle Internet Financial and will be integrating its USDC stablecoin."
