Certificate of Participation NFT Issuance Experience

cost effectiveness

The market price fluctuates, so we cannot make any promises, but we are told that it is usually around 5-15 yen per case.

Cheaper compared to making and handing out stickers.

Unlike stickers, it would be interesting to have developmental features such as "if you have it, you can do something" or "if you collect a lot of stickers, you can level up".

I'm more inclined to publish realistically.

I got the OK from the leader, Mr. Ukai, to give out the participation certificate NFT at the Unexplored Junior event.

If not, I was going to hand them out privately in the form of "proof that I met with Nishio."

The image and description are prepared, and when you are about to publish, you realize that you need to prepare the MATIC first.

Actually, the biggest hurdle was preparing MATIC.

Day 1

I had Ethereum on Coincheck, so I figured I could convert about $10,000 worth to MATIC.

→No MATIC at Coincheck.

I looked into how to obtain MATIC, but could not determine which of the Google search results were credible information.

report

Images and descriptions are ready.

I realize I had to prepare a MATIC when I tried to issue it.

I don't know how to buy MATIC, so I'll look into it.

1: Articles found on the Internet

1-1: An article about creating an account on an exchange (Bitpoint) where you can buy MATIC.

1-2: Article that says buy XRP and exchange it for Bybit.

1-3: Article on how you can buy with MetaMask, but your credit card company may reject it.

Try 1-3 -> I can't see the link to the purchase button (or can't access it from within Japan?)

I'm going to try 1-2 next, but before I do, I thought I'd better share all of this with you.

Method 2

Payment by bank transfer

They send tokens directly to your wallet address.

Method 3

Native's MATIC can be purchased at the exchange.

Sold at three locations, including SBI's.

Day2

I applied to open an account with SBI VC Trade.

Day3

The account is ready.

Deposit

10,000 yen for now

Is Mizuho not eligible for support?

I chose SBI Sumishin.

Use an immediate payment service

What a convenient time we live in!

(I thought again that I would stop using Mizuho for a good long while and focus mainly on places that are able to do new things like this.)

https://scrapbox.io/files/647b93de68fd14001ca4cef3.png

I decided to buy a 75matic.

https://scrapbox.io/files/647b93ebd50be1001c90bab5.png

Bought.

I got as far as creating an account with SBI VC and buying MATIC.

but I am stuck because I can't figure out how to send it to my wallet to use in MintRally.

I can connect the "SBI Web3 Wallet" to MetaMask, and it shows NFTs, etc. there, but...

Oh, okay, it's a layman's UI that doesn't show the menu for exchanging crypto assets by default.

I switched to something called "Trader Mode" and got the "Crypto Asset Exit" menu (self-resolving).

Attempting to Exit Crypto Assets

In order to dispatch a shipment, the destination must be registered first.

Trying to register a delivery destination

After you finish filling out the form, you find yourself being asked for a second PIN.

What is a second PIN?

Need to set up two-factor authentication.

I was able to register the destination.

I'm going to try to get only 1MATIC out of the garage for now.

I received something called an "Outgoing Reservation Email."

When you click on the link in that email, it will say "Your outgoing reservation has been accepted.

They'll email me when it's done, I'll wait.

relevance

From September 28, 2022, we will begin obtaining and storing information regarding the "purpose of the transfer" when customers newly exit (send externally) cryptographic assets in response to the Travel Rule.

Please see below for details.

SBI VC Trade] Reservations for delivery accepted 11:47 AM

It's going to take me three hours.

I was able to leave the warehouse.

I'll pay you about 3 cents.

Error when trying to create event

"insufficient funds for gas * price + value: address 0xd50... have 966546521347084996 want 11345890700340000000"

I see. 1MATIC is not enough.

I have it set up to shoulder the gas bill (I pay for the gas and the recipient gets it free), but I mistakenly thought that it would be deducted from my address each time a pickup occurs, with no particular basis in fact.

No, they didn't. They paid in advance for the maximum number of people they decided on the first time.

At this time, they had 100.

I only put in about a dollar and they're trying to pay me about ten dollars, so that's not going to happen.

Make the number of issued cards 10.

Error stating that it is still not enough

It was late at night and gas was expensive.

https://scrapbox.io/files/647b9801dea9ec001cecd2a7.png

I'm going to leave the rest of the 74MATIC and go to bed.

Well, but if I had tried 75 MATIC from the beginning, I think I would have issued 100 cards without realizing how expensive gas was or that I had to pay in advance, so the learning curve was maximized.

Day 4

11:00

https://scrapbox.io/files/647b98e0c58ab4001c5c7f86.png

I see, less than half the price of yesterday.

Weekly graph

https://scrapbox.io/files/647b9901313b1b001cc658c7.png

I see what you mean - it's expensive at night.

10 cards issued

https://scrapbox.io/files/647b998dc75d27001c47332b.png

Paid 76 cents, gas cost 14 cents, total 90 cents.

It's just barely 1 MATIC on a regular gas bill, so it's no wonder it wasn't viable with the high late night gas prices.

An event page could be created!

https://scrapbox.io/files/647b9a7fb3b062001babaf5e.png

The NFT could be obtained from the event page!

https://gyazo.com/f8e4737e338bd2cafe62210577b66f11

In OpenSea, it is initially in "Other" and "Hidden".

'Redisplay' so others can see it.

Service Description

We are looking for colleagues to help us make this an even better open source project as we work to expand functionality, improve usability, and address accessibility issues.

How to get MATIC, or if I had been alone, I would have failed.

Social Hack Day itself issues a participation certificate NFT.

https://gyazo.com/d68b0457b8780640055fe9f667805995

Surprisingly, the service itself currently has no data (= everything is on the blockchain).

The fact that this kind of service can be realized with it is interesting, and I feel a paradigm shift.
