USD Coin (USDC) is a relatiy stablecoin pegged to the US dollar. Circle and Coinbase collaborate and launched USDC on September 26, 2018.

In short, USDC works to tokenize US dollars and facilitate their use over the digital blockchains. Moreover, USDC token can be exchange to US dollar, this is done with ERC-20 smart contract.

The main advantages of USDC is that it brings much-needed stability to cryptocurrencies and also allow people to move US dollar anywhere in the world within minutes using the block chain.

How Does USD Coin Work?

USD Coins aren’t just issued out anyhow, the company Circle LTD ensures that every USDC token is backed with a single US dollar.

Tokenization: is the process of whereby the US dollars is turn into USDC tokens

Tokenizing USD into USDC in process:

  • The User send a US dollar to the token issuer's bank account.
  • The issuer then use USDC smart contract to create an equivalent amount of USDC.
  • Then the created USDC are given to the user, while the substituted US dollars are held in reserve.
  • The user then receive the USDC token equivalent to his/her US dollar.

Redeeming USDC: this is the process of changing USDC to US dollar.

This process is as easy as creating the token, except the process is reversed:

  • The user want to redeem his/her USDC to US dollar, the user then sends a demand to the USDC issuer to redeem an equivalent amount of USD for USDC tokens.
  • Then the issuer sends a demand to the USDC smart contract to exchange the tokens for USD and remove an equivalent amount of tokens out of the circulation.
  • The issuer then sends the demanded amount of USD from its reserves back to the user’s bank account. The user receives the US dollar amount equivalent to the USDC tokens he/she redeemed.
