The BlueMan Field Guide.
Own it. Understand it. Keep it safe.

For many of us, BlueMan is the first NFT we have ever owned. That is exactly who this guide is for. No jargon, no hype: what you own, how it works, how scammers try to take it and how to sell it safely.

What is BlueMan?

BlueMan is the character at the heart of SuccessPictures, the illustration project that has been sharing hand-drawn ideas and “aha” moments with a community of hundreds of thousands of people since 2018.

The BlueMan NFT Collection turns that character into something a single person can own: 111,111 unique artworks, each one drawn by hand. No AI, no generator mixing random layers. They are released a few pieces every day over 11 years, as a free gift to the people who followed the journey from the start.

So what is the point?

Most NFT projects ask “what can I do with my NFT?”. BlueMan asks a different question: “What can I build with my BlueMan?” Your BlueMan can become the face of a clothing line, a children’s book, a café, a podcast, a sports club or your online identity. It is a character you own and build with, not a lottery ticket.

What do you actually own?

An NFT is not a picture file sitting on your phone. It is a line in a public record that says: “BlueMan #29 belongs to wallet 0x7a…”. Everybody in the world can read that line, and nobody can change it except the owner of that wallet.

  • The token is the proof of ownership. It lives on the Ethereum blockchain.
  • The artwork is stored permanently on Arweave, a network built to keep files forever. Your token points to it.
  • The rights: the BlueMan project gives the holder the right to build with their character, commercially too.

Good to know

Everything travels with the token. If you sell or give away your BlueMan, the new owner gets the artwork and the rights. You do not keep a copy of the rights after a sale.

How a blockchain works

Picture a notebook that records who owns what. Now picture thousands of identical copies of that notebook, kept by computers all over the world. Every few seconds a new page (a “block”) is added, and every copy checks it before writing it down. Each page is sealed to the page before it, which is why it is called a chain.

Four linked blocks. Each block records transfers, for example BlueMan #29 moving from one wallet to another.BLOCK 1#29 mintedto 0x7a…sealedBLOCK 2#30 mintedto 0x91…sealedBLOCK 3#29 sold0x7a… → 0xc4…sealedNEW BLOCKbeing checkedby everyone…
Every transfer of every BlueMan is written into this shared record, forever.

What this means for you

  • Nobody can fake your ownership. Not a website, not a scammer, not even the BlueMan team.
  • There is no undo button. A transfer, once confirmed, cannot be reversed. There is no bank to call.
  • Everything is public. Anyone can see which wallet owns which BlueMan. That is fine: seeing is not the same as touching.

Wallets, addresses and the Secret Recovery Phrase

A wallet such as MetaMask does not “contain” your BlueMan. Your BlueMan lives on the blockchain. The wallet holds the key that proves you are allowed to move it.

Your public address

0x7a3f…c91e

Like your home address or IBAN. Share it freely: people use it to send you things and to check what you own. Our verification only ever needs this.

Your Secret Recovery Phrase

12 or 24 ordinary words

Like the master key to your house. Whoever has these words owns everything in the wallet, from any device in the world, instantly. They are the only way to restore your wallet.

How to store your recovery phrase

  • Write it on paper (or stamp it in metal) and keep it somewhere safe at home.
  • Never as a photo, a screenshot, a note on your phone, an email or a cloud file.
  • Never type it into a website, a form or a chat. MetaMask itself only asks for it when you restore a wallet.
  • Never read it out on a call or show it during screen sharing.

The one rule

No real company, support agent, moderator or BlueMan team member will ever need your recovery phrase. Anyone who asks for it is stealing from you.

Gas fees: what costs money and what doesn’t

Gas is a small fee paid in ETH to the network for writing something new into the shared record. Reading the record is free. Signing a message is free. Only actions that change ownership or permissions cost gas.

What you doWhat MetaMask showsGas?
Look at your BlueMan on OpenSea or EtherscanNothingFree
Register on the BlueMan Radar (first time)Nothing, you only paste your public addressFree

Rule of thumb

If a site says it just wants to check or verify you, and MetaMask suddenly shows a gas fee or the word “approve”, close the tab. Verifying never needs a transaction.

How to check your BlueMan yourself

You never have to trust a screenshot or a stranger. You can look up the truth in under a minute:

  1. Open OpenSea by typing opensea.io yourself and open the official BlueMan collection.
  2. Search your token number, for example 29. The page shows the current owner’s address.
  3. Compare it with the address in your MetaMask (top of the app, starts with 0x). Same address: it is yours.

Want the raw record? This is the one and only official BlueMan contract on Ethereum:

0x35521e69d9687274e8b81f1e7aa02e1ee1d541aaView on Etherscan →

A BlueMan from any other contract address is not a real BlueMan, however good it looks.

The golden rules

Almost every stolen NFT is lost the same way: someone is rushed into clicking or signing something. These rules stop nearly all of it.

  1. Your recovery phrase stays on paper. Nobody legitimate ever asks for it.
  2. Type addresses yourself. Reach OpenSea and this site by typing opensea.io and blueman.io or using your own bookmark, never through a link in a DM, email or ad.
  3. The team never DMs first. Real announcements are posted publicly on our official channels.
  4. Read before you sign. If you do not understand what MetaMask is asking, press Reject. Rejecting is always safe.
  5. Urgency is the scam. “Only 10 minutes left”, “your wallet will be frozen”, “claim now” are designed to stop you thinking.
  6. Free money is never free. Unknown NFTs or tokens that appear in your wallet are bait. Do not try to sell or “claim” them.
  7. Sell only on the marketplace. Never send your BlueMan first and wait for payment.
  8. Nobody needs your screen. Never share your screen or install remote-support apps for “help”.

Signatures vs. transactions: read before you click

MetaMask can ask you for two very different things:

A message signature

Like signing your name to say “yes, this wallet is mine”. Free. A safe login message is plain text you can read.

A transaction

Changes something on the blockchain: moves an NFT, spends ETH or gives someone permission. Costs gas and cannot be undone.

Exactly what BlueMan will ask you to sign

First-time registration on the Radar needs no wallet connection and no signature at all. Only when a BlueMan is already registered and you want to take over its spot, we ask for one signature. It always looks like this:

Signature request · blueman.io
BlueMan Community Radar VerificationWallet: 0x7a3f…c91eToken ID: #29Nonce: 4f9c2e81…
Network fee: noneRejectSign
  • It shows your own wallet address and your token number.
  • It is plain text and contains no price, no token amounts and no gas fee.
  • If anything claiming to be BlueMan asks you to approve, pay, or sign something you cannot read, it is not us.

“No gas” does not automatically mean “safe”

Some signatures are free but still give away your NFTs, for example a hidden marketplace listing at a price of zero. Stop and press Reject if a signature request on a site you did not open yourself shows any of these:

  • setApprovalForAll or “Allow access to all your NFTs”
  • Permit, Permit2 or “spending cap”
  • Seaport, “offer” and “consideration” lists (that is a sale order)
  • Long unreadable code starting with 0x…
  • Any amount, price or token list you did not expect
  • “Switch to smart account”, “Upgrade account” or “Delegate” on a site you did not open for that (why this is so dangerous)

When are Seaport signatures normal?

Only when you are on opensea.io, listing your BlueMan at a price you just typed in. Anywhere else, reject.

“Upgrade your account”: the newest trick

Since an Ethereum update in 2025, a normal wallet can be turned into a “smart account”. Wallets use this for useful features, and MetaMask may offer it to you itself. Scammers use the same feature: with one signature you hand control of your whole wallet to their code. Not one NFT, not one token, everything, including whatever you receive later.

It usually looks harmless: a pop-up that says “Switch to smart account”, “Upgrade account”, “Enable batch transactions” or “Delegate”, often with no gas fee.

  • Only accept an account upgrade inside the MetaMask app itself (Settings), never because a website asked for it.
  • A website that only wants to verify you, give you a reward or show you a collection never needs to upgrade your account.
  • If you already signed one on a strange site: treat the wallet as lost. Follow If something already went wrong and move everything to a new wallet.

Why this one is so dangerous

Most people have learned “never give your phrase” and “don’t pay gas on a strange site”. This trick asks for neither. It looks like a free, friendly upgrade.

The most common scams, and how they look

The “support” DM

Looks like: a friendly message from “BlueMan Support” or “MetaMask Help” after you ask a question in a group.

Do: ignore and block. Real support never writes first and never asks for your phrase.

The lookalike website

Looks like: blueman-claim.io, bIueman.io (a capital i instead of l), opensea-verify.com. A perfect copy of the real design.

Do: use your own bookmarks. Check the address bar before connecting anything.

The “free mint” or airdrop

Looks like: “BlueMan Season 2 free claim, only today!” with a link, often from a hacked account you follow.

Do: check the official channels. If it is not there, it does not exist.

The approval drainer

Looks like: a site asks you to “verify” or “claim”, then MetaMask asks to approve access to your NFTs.

Do: reject. One approval lets the scammer take every NFT in that collection later, without asking again.

The surprise NFT

Looks like: an unknown NFT or token appears in your wallet with a link to “claim your reward”.

Do: nothing. Do not click, sell or burn it. Hide it in your wallet and move on. More

The “let me help” call

Looks like: someone offers to walk you through a problem on a video call, asks you to share your screen or install AnyDesk/TeamViewer.

Do: end the call. They are waiting for your recovery phrase to appear on screen.

The poisoned address

Looks like: a tiny transfer from an address that starts and ends exactly like one you use, so it sits in your history.

Do: never copy an address from your transaction history. Check every character, not just the start and end.

The fake marketplace email

Looks like: “You received an offer for BlueMan #29, accept here” or “your listing expires”.

Do: open OpenSea yourself and check your offers there. Never through the email link.

The patient friend

Looks like: a kind stranger who chats with you for weeks, then shares a “trading platform” where they make great returns. Your first small withdrawals even work.

Do: never invest through a platform someone you met online recommends. The early profits are bait for a bigger deposit you never get back.

The “test our game” offer

Looks like: a job, a paid beta test or a new Web3 game. You are asked to download an app or a file to get started.

Do: don’t install it. These files often steal browser data and wallets from your computer without you noticing.

Someone sent me a free NFT. What now?

Sooner or later an NFT or token you never asked for shows up in your wallet. Often it looks like a voucher: “You won 2 ETH, claim at…”, “BlueMan holder reward” or “Trade this NFT for a rare one”.

The good news

Receiving it does nothing. On Ethereum nobody can “accept” or “refuse” an NFT, it simply appears. Your wallet is still safe at this point.

Where the danger starts

The NFT is bait. Its picture or description sends you to a website. That website then asks you to connect your wallet and sign something to “claim”, “trade” or “verify”. That signature is what gives away the contents of your wallet: an approval for all your NFTs, a hidden sale, or an account upgrade that hands over everything.

What to do

  • Ignore it. In MetaMask and on OpenSea you can hide it, so it stops bothering you.
  • Don’t visit the link or scan the QR code in the picture.
  • Don’t try to sell, send or “burn” it. Doing so can also ask you to approve something.
  • Don’t believe a “BlueMan” logo on it. Anyone can make an NFT that looks like ours. A real BlueMan comes only from our contract address.

Fake wallets and search ads

Many beginners search “MetaMask” on Google and click the first result. Scammers pay for exactly that spot. Their ad leads to a perfect copy of the MetaMask website, or to a fake app or browser extension that sends your recovery phrase straight to them the moment you type it in.

  • Download MetaMask only from metamask.io, typed by hand, or from the official App Store / Google Play page whose developer is Consensys.
  • Skip the ads at the top of search results when you look for any wallet, exchange or NFT site.
  • A wallet app that asks you to import your existing recovery phrase right after installing deserves a second look: was it really the official app?
  • Never install a “wallet update” or “security plugin” that someone sends you.

Risks inside our own community

BlueMan is built around trust, and most people you meet here are exactly who they seem. That trust is also what makes a community attractive to scammers. The most convincing scam does not come from a stranger. It comes from someone who is “one of us”, or looks like it.

“Only for BlueMan holders” is not a safety label

Holders are free to build things with their BlueMan, and we love that. It also means anyone can start a “BlueMan” club, group, game, investment circle or token, and use our artwork while doing it. A project being exclusive to holders tells you nothing about whether it is honest. It can even be the hook: scammers know holders own something valuable.

Warning signs, even from people you know

  • You must send your BlueMan (or ETH) to a person’s wallet to “stake”, “lock”, “register” or “join the pool”.
  • “Verify you are a holder” asks for more than a plain-text signature, or asks for gas.
  • A guaranteed return, a doubling, or “early members earn the most”.
  • Pressure: limited spots, a deadline tonight, “don’t tell the others yet”.
  • A well-known member suddenly DMs you with an opportunity. Accounts get hacked and copied, with the same name and picture.
  • Nobody behind it is willing to be named, or questions in the group get deleted.

Before you join anything

  1. Check if it is official. Official BlueMan projects are announced on our official channels. If it is not there, it is a community project, which can be great, but it is not ours.
  2. Ask in public. Post the question in the open group, not in DMs. Honest projects welcome questions; scams avoid daylight.
  3. Keep your BlueMan in your own wallet. Holder perks can be checked from your public address, exactly like our Radar does. Nothing legitimate needs your NFT in someone else’s wallet.
  4. Use a separate wallet for trying new community sites (see vault wallet).

Saw something suspicious?

Warn others in the open group and let the team know through the official channels. Speaking up protects the next person, and it is never rude to ask a project to explain itself.

Security · Practice

Practice: safe or scam?

Read each situation, decide, then tap to see the answer.

A Telegram user called “BlueMan Team” writes: “Your wallet is not synced with the Radar. Please validate it here within 24 hours.”

Scam. The team never DMs first, wallets do not need “syncing” and the deadline is there to rush you.

On blueman.io/verify your BlueMan is already registered by someone else. MetaMask shows a plain text message with your wallet, your token ID and a code. No fee.

Safe. That is exactly our overwrite message: readable text, your own details, no gas.

A site says “Verify you are a holder to claim BlueMan Gold”. MetaMask asks: “Allow access to and transfer of all your BlueMan?”

Scam. That is a setApprovalForAll. Approve once and every BlueMan you own can be taken.

You typed opensea.io yourself, chose your BlueMan, set a price of 0.2 ETH and MetaMask asks you to sign a listing showing 0.2 ETH.

Safe. Listing is a free signature. You started it, on the real site, with your own price.

A buyer offers more than the floor price, but wants to pay by bank transfer. You send the NFT first, they pay after.

Scam. Once the NFT is sent it cannot come back. On the marketplace the NFT and the payment swap at the same moment.

A friendly expert in a group chat offers to fix your MetaMask problem over a video call. “Just share your screen.”

Scam. Screen sharing is how they read your recovery phrase or watch you approve something.

An NFT called “BlueMan Holder Reward” appears in your wallet. Its picture says: “Claim 0.5 ETH at bluemanreward.xyz”.

Scam. Receiving it is harmless, visiting the site is not. Hide it and move on.

A site you found through a Telegram link shows MetaMask asking: “Switch to smart account? No network fee.”

Scam. One signature can hand over your whole wallet. Only upgrade inside MetaMask’s own settings, never for a website.

A fellow holder starts a “BlueMan Builders Club”. To join, you send your BlueMan to his wallet for 30 days and get rewards every week.

Scam (or at best a huge risk). Nothing legitimate needs your NFT in someone else’s wallet. Holder perks can be checked from your public address.

You search “MetaMask download” on Google and click the first result marked “Sponsored”.

Risky. Fake wallet sites buy exactly that ad spot. Type metamask.io yourself instead.

If something already went wrong

Act fast, but stay calm. Do these in order:

  1. Stop interacting. Close the site. Do not sign or approve anything else.
  2. Remove permissions you gave. Check your wallet on revoke.cash or the Etherscan Token Approval Checker and revoke anything you do not recognise. Revoking costs a little gas.
  3. If you typed or showed your recovery phrase anywhere: that wallet is lost for good. Create a brand-new wallet with a new phrase and move everything that is left right away.
  4. Tell the community through the official channels, so others are warned about the same trick.
  5. Report it to the police and keep the scammer’s address, links and messages as evidence.

Watch out for the second scam

After a theft, “recovery experts” appear and promise to get your NFT back for a fee. They cannot. A blockchain transfer cannot be reversed, and they are the same people coming back for more.

Level up: hardware wallet and a vault wallet

Once you feel comfortable, two habits make you much harder to rob:

  • A hardware wallet (for example Ledger or Trezor) keeps your key on a small device. Nothing moves without pressing a physical button, so a hacked computer alone is not enough.
  • Two wallets: a vault that holds your BlueMan and never connects to new sites, and an everyday wallet for trying things out. If the everyday wallet gets tricked, your BlueMan is not in it.

How selling works on OpenSea

  1. Type opensea.io yourself and connect MetaMask. Check the address bar.
  2. Open your profile, choose your BlueMan and press List for sale.
  3. Set your price and duration. OpenSea shows the fees and exactly what you will receive before you confirm.
  4. First time only: MetaMask asks to approve the BlueMan collection for OpenSea. This is a one-time transaction with gas, and it is normal only on opensea.io.
  5. Sign the listing. Free. Check the price in MetaMask matches what you typed.

When someone buys, the BlueMan and the payment swap in a single step. You do not need to do anything else.

Changing your mind

To lower a price you can usually just list again. Cancelling a listing may need a small gas fee; OpenSea tells you before you confirm.

Selling · 2 min read

Accepting offers safely

  • Check offers only inside OpenSea, never through an email or DM link.
  • Offers are usually in WETH (wrapped ETH, worth the same as ETH). That is normal.
  • Before you confirm, read the amount in MetaMask. It should match the offer, minus the fees OpenSea showed.
  • Accepting an offer is a transaction, so it costs gas.
  • Be careful with offers far below what you expect. One wrong click and the sale is final.

Selling · 2 min read

Never sell outside the marketplace

The marketplace protects both sides because the NFT and the money swap at the same moment. Outside it, someone has to go first, and that someone always loses.

  • “Send it first, I will pay by bank transfer / PayPal / crypto.”
  • “Use my escrow service.” (It is their own website.)
  • “Pay a small verification fee and then I can release the money.”
  • “My payment is stuck, please sign this to unlock it.”

A serious buyer can simply make an offer on OpenSea.

Selling · 1 min read

After the sale

  • Your pin on the Global Map is marked Owner changed. The new owner can place their own pin through Verification.
  • The artwork and the right to build with that BlueMan now belong to the buyer.
  • Selling for profit may be taxable where you live. Keep a note of the date and price, and check your local rules.
