How Do I Buy, Sell, or Mint NFTs?

You can buy, sell, and mint NFTs by just describing what you want — no marketplace UI needed. Bankr handles the rest and confirms every purchase or sale before executing, so you'll see the price, collection, and chain before anything happens.

What You Can Do

  • Buy NFTs — purchase from supported marketplaces

  • Sell NFTs — list your NFTs for sale

  • Mint NFTs — mint from active collections

  • View your collection — see all NFTs in your wallet

Example Prompts

  • show me my NFTs

  • what NFTs do I own on base?

  • mint an NFT from [collection name]

  • buy the floor NFT from [collection]

  • list my NFT for sale at 0.5 ETH

Supported Chains

  • Base — buy, sell, and mint, with gas sponsorship

  • Ethereum — buy, sell, and mint (gas not sponsored)

  • Polygon — buy, sell, and mint with gas sponsorship

  • Unichain — buy, sell, and mint with gas sponsorship

NFTs are not currently supported on World Chain, Arbitrum, BNB Chain, Solana, or Hyperliquid.

Viewing Your Collection

Ask show me my NFTs or what NFTs do I have? — Bankr shows the collection name, token ID, and which chain each NFT lives on.

Good to Know

  • Gas is sponsored on Base, Polygon, and Unichain — minting and buying there costs only the NFT price itself.

  • On Ethereum, keep ETH for gas on top of the purchase price.

Common Issues

  • "NFT not found" — check the collection name and chain.

  • "Insufficient funds" — you need enough of the native token (ETH, POL) to cover the price plus gas on non-sponsored chains.

  • Can't see a recently minted NFT — on-chain data can take a minute to update. Ask again shortly.
