Quiz time ⁉

Saw my latest private listings to Opensea 🧵/📺?

1️⃣ Which collection would be listed with this signature? What tokenIDs?
Hint: 0x8943C7bAC1914C9A7ABa750Bf2B6B09Fd21037E0

2️⃣ Which of the two signatures would "sell" your NFTs for free? And why?

No clue? Read on. ImageImage
Created this 🧵: "Always read what you're signing!" last week. There's a 20 minute video at the end of it, explaining details on Opensea listing signatures.

If you haven't be sure to check it out! ⤵

The amount of answers doesn't surprise me measured with my engagement.

"Always read what you're signing!"

Ever heard that saying in web3?

I did.

So here's how to READ and RECOGNIZE we're signing an listing to Opensea's Seaport protocol (that we might don't want).

#SaferNFTs 🛡 1/13
Everyone who's been following me for a while knows I tweeted a lot about signature / listing sc4ms.

"Offerer" is one of the biggest red flags you're looking for. 🚩

The message on the right is something you should NEVER see and NEVER expect on a non-marketplace website.

But before we take a look at the drainer above - let's analyze what an legit Opensea listing signature would look like. 💡

How to ⁉

Mint your NFT directly from a contract via @etherscan.

Hope this eliminates a lot of approval for alls and malicious signature signs on sc*mmy mint websites.

A detailed tutorial video on how to is in the last posts! 🎥

A step by step 🪡🧵

#SaferNFTs 1/13
First we need to know the contract address of the project that we want to mint.

Several approaches to get it without visiting the website:
1) Discord (official links channel)
2) Opensea (should be listed, 'cause: never be first to mint)
3) Project's Twitterpage

#SaferNFTs 2/13
Example: Looking for the contract address on Opensea?

Open the collection on Opensea, navigate down.
Under traits of an NFT, expand the "Details" tab. Clicking on contract address views it on etherscan.io directly.

Web3 basics 101 - Your seedphrase is something you want to protect at ALL cost. If you hand out your seedphrase - it's game over for that wallet (+subwallets).

Here’s a🧵about companies entering web3 and not properly putting disclaimers up for user security.

#SaferNFTs 1/10
I chose @Stepnofficial as an EXAMPLE for this🧵, applies to all others.

For those unfamiliar with #STEPN - they are essentially onboarding people to web3 to earn crypto through their app while being active / moving / running. Which - as a concept is a cool idea.

#SaferNFTs 2/10
STEPN launched on $sol originally, expanded to $bnb and now added $eth. Different chains are referred to as realms. Basically = servers, if you're familiar with MMORPGs. Solana Realm, BNB Realm and APE Realm.

Ok, onto the security part already @Wii_Mee!

Most of your answers said: #2. 🥁

Yes, you didn't see the Origin - which would've made it too easy for y'all! 😂

Here's your answer (dont click the quoted tweet, lol):
💡Solution:

Actually all these 3 screenshots were from @opensea while interacting with the new Seaport protocol.

Correct answer (with known Origin): 2!

1 by 1 screenshot explanation below ⤵
#1
"Set Approval For All" txn would be a 🚩 and a sign to run away as fast as you can.

Interacting with a marketplace you have to give out the approval for the first listing of a collection, so they can execute a transfer on your behalf if your NFT sells.

Will reveal the answer tomorrow or so, so me liking your tweets doesn't mean you're right necessarily. ☝️

Now I had everyone's attention with the wallet hygiene 🧵:

Time to compare:
etherscan.io and / or revoke.cash to revoke permissions you gave to your wallet address?

Had split the video, because I'm 🇪🇺 and still can't use Twitter blue.
