Watch out for Phishing Attempts
Make it a point to double check URLs prior to clicking them, even in social media and emails. If you click on links provided from unverified sources, you risk losing access to your NFTs.
Smart Contracts Audit
Prior to buying NFTs off OpenSea, make use of Etherscan to look over pending and active smart contractsfor any potential exploits or bugs.
Best Practices for NFT Security
Use a Secure Wallet: It is best to protect NFTs with hardware wallets like Ledger or Trezor since they store assets offline.
Enable Two-Factor Authentication (2FA): Make 2FA compulsory to all accounts as a basic form of added security for the account.
Enhance Password Strength: Ensure to have robust and distinct passwords for each NFT platform and wallet associated.
Bear Phishing Scams in Mind: Ensure to authenticate platform links alongside any emails received, avoiding malicious websites.
Conduct Smart Contract Audits: Conduct security audits alongside other checks before engaging with smart contracts.
Update All Software Regularly: Periodically renew wallet applications and portal softwares to maintain security standards.
Store Recovery Keys Safely: Ensure storage for recovery phrases is thoroughly offline and secure.
Avoid Using Public Wifi Networks: Avoid spending time on unprotected networks iscritical for transactions regarding NFTs and VPNs are recommended for such cases.
Use Cold Storage for NFTs Held Long-Term: For easily accessible long term storage, transfer NFTs into cold wallets.
Confirm Transfer Details: Once transaction confirmation takes place, ensure to authenticate wallet address and details.
Securing Your NFTs with Smart Contracts
Recognize the Weaknesses in Smart Contracts
There are a variety of self-enforcing agreements known as a smart contracts where one or multiple parties are executed automatically. Just like any form of technology, it is vulnerable to unplanned attacks. Prepare for an audit and construct multi-step secured codes.
Verification of a Smart Contract is Important
Paying for Just One Audit: Make sure that there are respectable auditing agencies reviewing the contract. Sometimes there’s an audit waiting to be claimed on Certik or Quantstamp, firms that analyze vulnerable points in smart contract codes.
Review the Contract Corde on SOP: In possible cases try and analyze a smart contract’s code personally and in situations where you can’t, get a professional.
Established NFT Standard
ERC-721 and ERC-1155: These two are considered the most used policies concerning NFTs on Ethereum. They offer a sound stamp of best practices making the system less receptive to attacks.
Stick to Trusted Platforms: Select NFT marketplaces and platforms which are trusted and utilize safe smart contract practices.
Be Cautious With Unverified Contracts
Refrain from engaging with smart contracts from unverified or unknown origin. When buying an NFT, always check if the contract is verified on Etherscan or Rarible to avoid unverified contracts.
Use Safe Transaction Techniques
Employ Multi-Signature Contracts: For valuable NFTs, it may be wise to utilize a multi-signature contract that requires more than one private key to approve a transaction.
Restrict Permission Granted: Reduce the level of control permitted to the smart contract. Do not give blanket approvals for transfers or access to the NFTs you own.
Be Aware of Contract Revisions
Stay up to date with any revisions to the smart contract of the NFT you own. Sometimes developers upgrade contracts and patch them in other cases to address vulnerabilities.
Follow the security advisories related to the blockchain you are on, such as Ethereum or Solana, and monitor them for any known exploits to the smart contracts.
