How to list NFTs on Tensor? (Solana Ecosystem)

Understanding Tensor's Role in Solana NFT Trading

1. Tensor operates as a decentralized NFT marketplace built exclusively for the Solana blockchain, emphasizing speed, low fees, and on-chain order book transparency.

2. Unlike centralized alternatives, Tensor does not hold custody of user assets; all listings are executed via smart contracts directly on Solana.

3. The platform supports both fixed-price sales and Dutch auctions, with native integration into Phantom, Backpack, and other Solana-compatible wallets.

4. Listings appear instantly on-chain once confirmed, and metadata is verified against the official token standard—Metaplex’s Token Metadata Program.

5. Users must hold SOL to cover transaction fees and initialization costs, but no platform-specific tokens are required to list or trade.

Prerequisites Before Listing an NFT

1. A Solana wallet such as Phantom or Backpack must be installed and funded with sufficient SOL for gas fees.

2. The NFT must be minted using Metaplex standards and verified on-chain via the correct metadata URI and update authority signature.

3. Ownership of the NFT must be confirmed on-chain; Tensor checks wallet ownership in real time before allowing listing actions.

4. The collection must be verified on Tensor if it intends to display a verified badge—this requires submitting proof of control over the collection’s update authority.

5. No KYC is enforced by Tensor, but some collections may impose their own transfer restrictions through custom program logic.

Step-by-Step Listing Process on Tensor

1. Navigate to tensor.trade and connect your Solana wallet using the top-right Connect Wallet button.

2. Click the My Collections tab, then select the specific NFT you wish to list from your wallet holdings.

3. Choose between Fixed Price or Dutch Auction; enter the desired price in SOL or supported SPL tokens like USDC.

4. Set optional parameters: listing duration for Dutch auctions, royalty recipient address (if different from mint authority), and whether to allow offers.

5. Confirm the transaction in your wallet; upon Solana confirmation, the listing appears live under the Active Listings section.

Managing and Updating Listings

1. Active listings can be edited only before any bid or purchase—price adjustments and duration extensions require a new on-chain instruction.

2. Canceling a listing triggers a small fee denominated in SOL, which covers compute and write-lock release on the orderbook state.

3. If the NFT has associated royalties, Tensor enforces them automatically during sale settlement using the on-chain royalty account registered in Metaplex metadata.

4. Listings tied to frozen accounts or those with delegate restrictions will fail validation and return an explicit error message in the UI.

5. Tensor provides real-time analytics per listing, including view count, offer history, and floor price comparisons within the same collection.

Frequently Asked Questions

Q: Can I list an NFT that was minted on another chain and bridged to Solana?A: No. Tensor only accepts NFTs minted natively on Solana using Metaplex standards. Cross-chain bridged assets lack valid on-chain metadata signatures and fail verification.

Q: Why does my listing show “Verification Pending” even after connecting my wallet?A: This occurs when Tensor cannot confirm the NFT’s metadata URI resolves to valid JSON matching the Metaplex schema, or when the update authority is not properly signed.

Q: Is there a fee to list, or only when selling?A: There is no flat listing fee. However, every action—listing, editing, canceling—requires a Solana transaction fee, typically under $0.00025 at current network rates.

Q: Do I need to approve a token program before listing an SPL-based NFT?A: Not for standard Metaplex NFTs. Approval is only required for fungible tokens used as pricing denominations (e.g., approving USDC transfers before listing in USDC).
