Happy Black Friday. 

Are you a cryptonative looking to collect some crazy cryptocurrency memorabilia? Look no further.

I'm selling a Dennis Rodman-autographed PotCoin business card on my UMP storefront today.

WTF does Dennis Rodman have to do with crypto and what is UMP?
🧵1/

2/ In 2018, Rodman announced that he had arrived in Singapore for the meeting between his friend, Kim Jong Un, and President Trump. 

Rodman's travel was apparently supported by the cryptocurrency PotCoin.

3/ I obtained this autographed PotCoin business card years ago. It's authenticated by PSA
.

I've listed it for sale for $49 $USDC on my UMP storefront. 

This is far less than comparables are listed for on any other marketplace:

4/ What is UMP? 

 
@barabazs.eth and I just launched the MVP of our Universal Marketplace Protocol (UMP) on Base. 

UMP is a set of smart contracts that allow you to securely and privately buy and sell tangible goods without intermediaries.

5/ UMP is built on top of OpenSea's Seaport contracts, which you'll have to approve.

When you buy an item, you receive a receipt token. 
The payment goes to an escrow smart contract. 

The seller (me) can't get paid until the buyer confirms receipt and settles the transaction.

6/ After buying the item, the buyer securely send me their mailing address, end-to-end encrypted, over @xmtp  and I ship the item.

If anything goes wrong, @barabazs.eth is the arbiter. 

The sale has clear terms, provided in the listing and available at http://basicterms.ump.eth.limo.

7/ It's unlikely that anything will go wrong. 

But if your order gets lost in the mail or isn't as described, you can dispute the sale within 21 days and Barabazs will refund the item (we'll use a tracking number to prove delivery). 

Here's a video showing the whole process:

8/ My UMP Storefront is selling a lot of other crypto collectibles that most people have no idea exist. 

To set the prices, I found recent sales for similar items on eBay and BitcoinTalk and slashed the prices by 30-70%.

Crypto went up today. Spend some of those profits!

9/ Not into crypto collectibles? 

For about $3 worth of ETH or DEGEN you can test out our MVP by buying a pair of these high quality vinyl stickers.
