How to set up Solflare for Solana NFT minting? (Priority Fees)

Wallet Connection and Interface Setup

1. Visit Solflare.com and select either the browser extension or mobile app version based on your device.

2. Click “Create Wallet” or “Import Wallet” — if importing, enter your 12-word recovery phrase securely and confirm.

3. After setup, ensure your wallet displays a valid Solana address starting with “A”, “B”, or “C”, and verify that it holds at least 0.05 SOL for initial transaction fees and rent exemption.

4. Navigate to an NFT minting platform such as Tensor or Magic Eden, then click “Connect Wallet” and choose Solflare from the list of supported wallets.

5. Approve the connection request in the Solflare popup window — this grants read-only access to your public address and balance, not private key exposure.

Transaction Configuration with Priority Fees

1. When initiating a mint transaction, Solflare automatically displays the default fee estimate — usually under 0.000005 SOL — but this does not guarantee inclusion during network congestion.

2. Click the gear icon or “Advanced Settings” to manually adjust priority fees; values are expressed in micro-lamports per compute unit (µLAMPORTS/CU).

3. Set priority fee between 100,000 and 500,000 µLAMPORTS/CU during high-traffic periods like popular NFT drops, ensuring faster block inclusion without excessive overpayment.

4. Confirm that the total estimated cost — base fee plus priority fee — remains below 0.01 SOL unless executing multiple simultaneous mints.

5. Review the transaction preview: verify the program ID matches the official minting contract, check the destination token account, and ensure no unexpected instructions are appended.

Metadata and Token Standard Compliance

1. Before minting, prepare metadata JSON hosted on decentralized storage like Arweave or IPFS — Solflare does not host or validate metadata but requires its URI to be correctly formatted.

2. Ensure your NFT conforms to the Token-2022 standard if using extended features such as transfer hooks or permanent delegate authority — legacy Token-2022 mints may fail silently in Solflare if misconfigured.

3. Verify that the mint authority keypair used during creation is either your Solflare wallet’s keypair or a delegated signer explicitly authorized via instruction.

4. Confirm the freeze authority field is set to “None” unless intentional freezing logic is part of your project’s design — Solflare enforces strict validation before signing.

5. Double-check that the seller fee basis points field in metadata matches the intended royalty percentage — Solflare passes this value unchanged to the mint instruction.

On-Chain Confirmation and Post-Mint Verification

1. After signing, Solflare broadcasts the transaction directly to Solana’s RPC endpoints — no intermediary relayer is involved.

2. Monitor status using Solflare’s built-in transaction history tab or paste the signature into explorer.solana.com to view real-time confirmation progress.

3. Once confirmed, the NFT should appear under the “NFTs” section in Solflare within 10–30 seconds — delays beyond this indicate metadata resolution failure or incorrect token account linkage.

4. Cross-verify ownership by checking the associated token account’s owner field against your Solflare wallet address on-chain.

5. If the NFT fails to display, inspect the transaction logs for errors like “AccountNotFound”, “InvalidAccountOwner”, or “ComputeBudgetExceeded” — each corresponds to specific configuration mismatches Solflare flags pre-signature.

Frequently Asked Questions

Q: Can Solflare set dynamic priority fees based on real-time network congestion?A: No. Solflare does not auto-adjust priority fees. Users must manually input values after consulting live metrics from tools like solana.com/status or metrics.solflare.com.

Q: Does Solflare support compressed NFT (cNFT) minting natively?A: Yes — Solflare fully supports cNFT minting through compatible dApps, provided the transaction includes correct Bubblegum program instructions and valid Merkle tree proofs.

Q: Why does Solflare reject my mint transaction even though the same payload works in Phantom?A: Solflare enforces stricter runtime validation of instruction accounts and metadata URIs. Common causes include malformed JSON, missing image fields, or mismatched creator addresses in the metadata file.

Q: Is it possible to batch-mint multiple NFTs using Solflare without external tooling?A: Not natively. Solflare signs one transaction per mint. Batch operations require third-party tools like Metaplex CLI or custom scripts that generate and submit individual signed transactions sequentially.
