Frequently asked questions

Mintelier is a curated Ethereum-based marketplace built specifically for traditional artists. We turn original works into authenticated 1/1 NFTs and handle the technical layer (wallets, gas, smart contracts) so artists can focus on creating.

Most NFT platforms were designed by technologists for crypto-natives. Mintelier was built for artists who want the provenance and reach of blockchain without learning the entire stack. We curate quality over quantity and protect each artist's voice.

Any verified artist accepted through our curation process. Submit your portfolio from the Artists page and our team reviews submissions to keep the marketplace high signal.

We curate every artist and every drop. Instead of millions of unrelated assets competing for attention, collectors discover meaningful, vetted work with a verifiable trail of authenticity.

Yes. Mintelier runs an internal ETH ledger. You deposit ETH to a unique address assigned to your account, and the platform settles mints, bids, sales and royalties instantly without on-chain gas for every action.

A small mint fee is deducted from your wallet at mint time. Secondary sales pay creator royalties (set at mint, between 3% and 20%) plus a transparent marketplace fee. All fees are displayed before you confirm any action.

A 1/1 (one of one) NFT is a unique digital certificate of ownership for a single, original work. Just as an original painting exists once, a 1/1 NFT preserves that uniqueness on the blockchain. There is only one.

No. The NFT is the certificate of authenticity and ownership. The artwork is the image, video or file it points to. Owning the NFT means owning the verified original record of that work.

1/1s preserve scarcity and align with how traditional fine art is valued. Mintelier focuses on 1/1 because it respects the years artists invest in building a distinct, original practice.

Every minted piece carries a unique six character alphanumeric Mintelier ID, shown on its detail page. Use it for provenance lookups and authenticity verification.

Provenance is the documented history of an artwork. Who made it, when, and every owner since. On Mintelier this history is recorded automatically and cannot be edited or erased.

The original mint is signed by the verified artist's account. Every subsequent sale, bid, and ownership transfer is logged atomically. The Owner field on each artwork always reflects the current rightful holder.

No. The chain of custody is append only. Once a transaction is written it is permanent and publicly verifiable.

At mint you set a royalty between 3% and 20%. Every secondary sale routes that share back to you automatically. No claim, no chase, no missed payments.

Open the artwork's detail page. The golden ID bar displays the Mintelier ID, the current Owner, the original creator, royalty percentage, and full bid and sale history.

Not for everyday use. Your Mintelier wallet works on our internal ledger. MetaMask becomes useful when you want to deposit ETH from outside, withdraw to a self custodial wallet, or move artwork off platform later.

MetaMask is a self custodial digital wallet that lets you hold ETH and NFTs and connect to Web3 apps. Think of it as your personal vault and identity on the blockchain.

Download MetaMask from metamask.io or your device's official app store. Open it, choose Create a New Wallet, set a strong password, then carefully record the 12 word Secret Recovery Phrase it shows you.

Your Seed Phrase (also called Secret Recovery Phrase) is the master key to your wallet. Anyone with it controls everything inside. Write it on paper, store it offline in a safe place, and never share it with anyone. Not friends, not support, not Mintelier.

Write it by hand on paper or stamp it onto a metal backup plate. Keep at least two copies in separate secure locations such as a home safe and a bank deposit box. Never screenshot it, save it in notes apps, email it, or upload it to the cloud.

If you lose it and the device too, recovery is essentially impossible. No company, exchange, or support team, including MetaMask itself, can restore access. Safeguarding it is the single most important responsibility of self custody.

Never. No legitimate platform will. If anyone (by email, DM, fake site, or so called support agent) asks for your Seed Phrase, it is a scam. Walk away.

Buy ETH on a regulated exchange like Coinbase or Kraken, then withdraw to your MetaMask address. PayPal and ACH bank transfers are supported in some regions, either via the exchange or directly inside MetaMask's Buy tab.

Open Wallet from the Account menu and claim your unique deposit address. Send ETH from MetaMask, an exchange, or any external wallet. Once confirmed and reconciled, your balance updates automatically.

Always Ethereum mainnet unless explicitly told otherwise. Sending on the wrong network can delay or permanently lose funds. Double check the network in your sending app before confirming.

Yes, always. The first time you use a new address, send a small amount, confirm it arrives, then transfer the rest. Blockchain transactions are irreversible.

A blockchain is a public, append only digital ledger. Every transaction is permanent, transparent, and cannot be altered. This makes it ideal for proving who created an artwork, when, and who currently owns it.

Gas fees are small payments to the blockchain network for processing transactions like minting or transferring an NFT. They fluctuate with network demand. On Mintelier, most everyday actions happen on our internal ledger with no per action gas.

A smart contract is a self executing agreement written in code on the blockchain. When the conditions are met, for example when payment is received, it automatically transfers ownership and records the result. No intermediary needed.

Go to Mint, upload your image, set category, royalty (between 3% and 20%) and optional sale price. A small mint fee is debited from your Mintelier wallet. Your piece appears in My Collection immediately with its Mintelier ID.

Provenance fields such as creator, mint date and ID are immutable. You can adjust sale listing, price and description from the artwork's detail page as the current owner.

Place a bid and the amount is debited from your Mintelier balance and held in escrow. If the seller accepts, ownership transfers and funds release. If they reject, you cancel, or the listing closes, funds return to you in full.

Open the artwork's detail page. As the owner you see every active bid with Accept and Reject buttons. Accept settles the sale and credits your wallet. Reject returns the escrowed ETH to the bidder. Your dashboard also surfaces all bids received and bids placed across your collection.

Yes. Open the artwork and use the Withdraw button next to your active bid. The escrowed ETH returns to your Mintelier wallet immediately.

Sellers can decline any bid at their discretion. Common reasons include a higher competing offer, a target reserve not met, or a decision to keep the work. Your escrowed funds are returned immediately.

Ownership transfers to the buyer, the Owner field updates, your royalty rate is locked in for all future resales, and proceeds (minus royalties and marketplace fee) land in your Mintelier wallet.

Sessions persist on your device and refresh automatically. You stay signed in across visits until you explicitly log out from the Account menu.

Open My Profile from the Account menu. You can upload an avatar, set your bio and unique profile link, change password, manage socials, and submit KYC documents. All in one place.

Identity verification unlocks higher withdrawal limits and protects the marketplace from fraud. Submit documents from your Profile page. Reviews typically complete within 48 hours.

Yes. Documents are encrypted at rest and accessible only to trained admins for the duration of review. They are never shared with other users or third parties.

Request a withdrawal from Wallet with your destination ETH address. Our finance team reviews and broadcasts it on chain. You receive a notification with the transaction reference once it ships.

Never share your Seed Phrase, password, or private keys. Never enter your Seed Phrase on a website. Ignore anyone promising to double your crypto. Verify URLs carefully and bookmark Mintelier rather than clicking links from messages.

Log out of all sessions from My Profile, change your password immediately, and contact support through the Account menu. If you suspect your external wallet is compromised, move assets to a fresh wallet with a new Seed Phrase.
