Can I sell my NFT on OpenSea?
Learn about secondary marketplace options.
Yes! Your Certifium NFTs are standard ERC-721 tokens and can be sold on any compatible marketplace.
Selling on OpenSea: 1. Go to opensea.io and connect your wallet 2. Select Base network 3. Find your Certifium NFT in your profile 4. Click "Sell" and set your price 5. Sign the listing transaction 6. Your item is now listed!
**Important Considerations:**
- OpenSea charges a 2.5% fee on sales
- Certifium may have creator royalties (supports the platform)
- Buyer receives the NFT, not the physical item
- Physical item remains in Certifium vault until claimed
**Certifium Marketplace:** For the best experience, we recommend selling on Certifium:
- Direct access to serious collectors
- Verified grading information displayed
- Seamless vault custody transfer
- Lower fees
