How to mint an NFT on Solana? (Phantom wallet guide)

Setting Up Phantom Wallet

1. Visit the official Phantom website and download the browser extension for Chrome, Firefox, Brave, or Edge.

2. Install the extension and click “Get Started” to begin wallet creation.

3. Choose “Create a new wallet” and securely save your 12-word recovery phrase in an offline location.

4. Set a strong password for local access — this does not recover your wallet but unlocks the extension.

5. Confirm your seed phrase by selecting words in correct order to verify backup integrity.

Adding SOL to Your Wallet

1. Click the wallet icon in your browser toolbar and select “Receive” to reveal your Solana address.

2. Copy the address and paste it into a centralized exchange withdrawal field when sending SOL.

3. Purchase SOL directly via integrated on-ramp services like MoonPay or Ramp if supported in your region.

4. Wait for network confirmation — Solana transactions typically settle in under 2 seconds.

5. Verify your balance appears correctly in the Phantom interface before proceeding to minting.

Selecting an NFT Minting Platform

1. Tensor is widely preferred for its gas-efficient minting tools and real-time marketplace analytics.

2. Magic Eden offers intuitive UI and supports both standard and compressed NFTs across multiple collections.

3. Exchange Art provides curated onboarding for artists with built-in royalty enforcement and metadata validation.

4. Hyperspace focuses on low-cost batch minting and integrates seamlessly with Phantom’s sign request flow.

5. Verify platform domain authenticity — phishing sites often mimic legitimate interfaces with subtle URL variations.

Preparing Digital Assets and Metadata

1. Format image files as PNG or JPEG under 10 MB; animated assets must be MP4 or GIF under 30 MB.

2. Write concise, accurate metadata: name, description, attributes in JSON format following Metaplex standards.

3. Host image and metadata on decentralized storage — Arweave is most commonly used for permanent immutability.

4. Validate your metadata structure using tools like Metaplex Candy Machine v3 validator or Solscan’s preview tool.

5. Ensure all attribute names avoid special characters and whitespace to prevent rendering issues on marketplaces.

Executing the Mint Transaction

1. Connect Phantom wallet to your chosen platform by clicking “Connect Wallet” and approving the session request.

2. Upload your asset file and paste the Arweave URI for image and metadata into the respective fields.

3. Configure mint parameters: supply count, price in SOL, royalty percentage (typically 5–10%), and freeze settings.

4. Review transaction details including compute unit estimation and priority fee adjustments before submission.

5. Sign the transaction in Phantom — confirm network ID is mainnet-beta and approve all instruction signatures.

Frequently Asked Questions

Q: Why does my mint transaction fail with “Compute budget exceeded”?A: This occurs when the instruction complexity surpasses default compute limits. Adjust priority fees manually or simplify metadata attributes.

Q: Can I mint an NFT without owning SOL?A: No. SOL is required to pay for rent exemption, transaction fees, and program execution costs on Solana.

Q: Is it possible to change the royalty percentage after minting?A: Royalty settings are immutable once written to the on-chain metadata account unless using programmable NFT standards.

Q: What happens if I lose my Phantom wallet password?A: The password only secures local extension access. Your assets remain recoverable using the original 12-word seed phrase.
