Digital🛢- Will you strike digital oil? — Issue #7 — The Best Joke Teller 🥁 & The Last Task

We have a Joke Telling Contest Winner 🥁

A few moments ago I closed voting for the joke telling contest. We have a winner!

The Winning Joke

And… the winning joke was:

The Last Task

It is now time for you to realize your last task. This task enrolls you in the raffle for the $500 in USDC. I have opened raffle enrollment in the smart contract, which also automatically closes voting. This means that no more than 14 people can enter the raffle since only that many completed Task #3.

Some Bonus Content: A Primer on USDC

So, what is USDC?

USDC is a stablecoin, meaning a cryptocurrency that is pegged to the US Dollar. The coins are born in a smart contract (ERC20, in case you are familiar) on Ethereum, owned by Coinbase. The way it works is that you ask Coinbase to convert the US Dollars that you have deposited on their platform to crypto dollars that allow you to interact with smart contracts. For every dollar you “convert” (in reality Coinbase just keeps it in their treasury), they mint a new USDC coin in their smart contract and they assign it to your Ethereum address. When you want your US Dollars back, you ask them to burn the USDC you have and assign the equivalent number of US Dollars to your Coinbase account, which you can wire out when you wish.

But the USDC you send us isn’t on Ethereum; it’s on Polygon

That’s right. It turns out you can bridge USDC from Ethereum to Polygon. I won’t get into the mechanics of this, but I’ll say that in case you need to transact using USDC on Polygon you can and they are equivalent to USDC on Ethereum. Actually, if you ever want to cash out the USDC on Polygon, at the moment, the simplest way is to bridge them back to Ethereum, and then send them to an online crypto brokerage which accepts Ethereum USDC, and then ask them to send you the US Dollars. Alternatively, you can pay other people for services using USDC on Polygon by sending to their Polygon address; or you can interact with smart contracts on Polygon with your USDC. For example, you can exchange USDC for MATIC or any other currency to buy NFTs or play games on Polygon that require upfront investments (like buying an NFT to play).
