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 SeaDrop mints, with gas sponsorship

  • Unichain — buy, sell, and SeaDrop mints, with gas sponsorship

  • Arbitrum — buy, sell, and SeaDrop mints, with gas sponsorship

  • Robinhood Chain — buy, sell, and SeaDrop mints, with gas sponsorship

Minting: SeaDrop (OpenSea) mints run on whichever of these six chains the collection lives on. Manifold mints work on Base and Ethereum only.

NFTs aren't supported on World Chain, BNB Chain, Arc, 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 most supported NFT chains, up to a daily allowance — see Supported Chains on docs.bankr.bot for current details.

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

  • Sending NFTs out of your wallet counts against the Allow NFT transfers setting in your Security controls, which caps how many NFTs can leave in a rolling 24 hours.

Common Issues

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

  • "Insufficient funds" — you need enough of the collection's currency (often ETH or WETH) to cover the price, plus gas on chains without sponsorship.

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

For more details, see the NFT documentation on docs.bankr.bot.
