How to link a MetaMask wallet to Blur? (Trading setup)

Connecting MetaMask to Blur Platform

1. Ensure MetaMask is installed as a browser extension on Chrome, Firefox, or Brave. Open the extension and verify your wallet is unlocked and contains sufficient ETH for gas fees.

2. Navigate to blur.io in your browser. Click the wallet icon located in the top-right corner of the Blur interface.

3. From the wallet selection modal, choose MetaMask. A pop-up window from MetaMask will appear requesting permission to connect.

4. Confirm the connection request inside MetaMask. The platform will display your connected wallet address and available ETH balance once approved.

5. Blur may prompt you to switch to Ethereum Mainnet if your MetaMask is set to another network. Select Ethereum Mainnet and confirm the network change in MetaMask.

Verifying Wallet Integration on Blur

1. After successful connection, your wallet address appears in the top navigation bar with a green checkmark indicator.

2. Access the Portfolio tab to view NFT holdings synced from your MetaMask address across all supported chains.

3. Check transaction history under the Activity section to confirm Blur recognizes recent on-chain actions tied to that wallet.

4. Attempt a test action such as opening an order book on a collection—Blur will trigger a MetaMask signature request if integration is fully functional.

5. If balances do not load immediately, click the refresh icon next to the wallet address or manually trigger a sync via the settings gear icon.

Gas Optimization for Blur Trades

1. Blur displays real-time gas estimates before executing any trade or listing action. These values are pulled directly from Ethereum’s current network conditions.

2. Enable EIP-1559 support in MetaMask settings to ensure proper handling of base fee and priority fee calculations during Blur interactions.

3. Adjust the gas fee slider in MetaMask’s confirmation window when prompted—Blur does not override user-selected gas parameters.

4. Monitor pending transactions using the Tx Hash link provided after submission; this opens Etherscan for live status tracking.

5. Avoid initiating multiple simultaneous actions—Blur queues operations but MetaMask may reject overlapping signature requests.

Security Considerations During Linking

1. Never enter your MetaMask seed phrase on Blur or any third-party site. Blur only requests cryptographic signatures—not private key exposure.

2. Confirm the URL is exactly https://blur.io with a valid SSL certificate. Phishing domains often mimic Blur’s UI with minor spelling variations.

3. Disable browser extensions other than MetaMask during the linking process to prevent script injection or unauthorized wallet access.

4. Review permissions requested by Blur: it reads on-chain data and signs transactions but cannot transfer assets without explicit user approval each time.

5. Use a dedicated MetaMask account for Blur trading rather than your primary wallet holding significant long-term assets.

Frequently Asked Questions

Q: Does Blur support hardware wallets like Ledger through MetaMask?A: Yes—connect your Ledger to MetaMask using the Ledger Live app and select Ethereum app. Then follow standard Blur connection steps. MetaMask acts as the bridge; Blur communicates only with MetaMask’s interface.

Q: Why does Blur show zero NFTs after connecting my wallet?A: Blur indexes NFTs based on on-chain ownership records. If your NFTs reside on a different chain (e.g., Polygon), ensure MetaMask is switched to that network before connecting. Also verify the NFT contract addresses are supported by Blur’s indexer.

Q: Can I link multiple MetaMask accounts to one Blur session?A: No—Blur allows only one active wallet connection per browser session. To switch accounts, disconnect the current wallet and reconnect the alternate MetaMask account.

Q: What happens if I revoke Blur’s access in MetaMask settings?A: Revoking access removes Blur’s ability to read your wallet state or request signatures. You must repeat the full connection flow to restore functionality.
