People often ask us why a smart contract firewall is needed. They say they’ve already had security audits for their DApps and that should mean they are fully protected. Security auditing can be an important step in effective smart contract protection. But now a new technology gives your smart contract complete security — the Decentralized Application Firewall (DAF).

While security pre-deployment solutions such as auditing help to protect the smart contract against programming errors and known vulnerabilities, a DAF gives you complete control over your transaction traffic. This protects against both programming errors and known vulnerabilities, as well as against hidden code vulnerabilities, stolen private keys, malicious employees, and numerous other security threats.

Lately, we’ve seen several smart contract attacks, such as the breaches that hit Bancor, KickICO, and SpankChain. Each of these attacks highlight the importance of protecting your transaction traffic. Since all smart contracts are deployed on the blockchain, there are many opportunities to find targets. Once attackers pick a suitable smart contract, they can compromise it and steal valuable tokens. All of this activity takes place in the background without the tech team’s knowledge. This is exactly where a smart contract firewall will protect you, by identifying and stopping unauthorized traffic.

SafeBlocks Firewall is the first DAF built to protect smart contracts. Upon activation, SafeBlocks Firewall reviews each validation request, and then returns an approval or denial response based on the security policies you’ve created.

SafeBlocks Firewall makes it simple to create and manage a security policy for your smart contract:

Implementation of SafeBlocks Firewall can be completed easily in just four steps:

Download the SafeBlocks template.

Add our hooks to your smart contract.

Create rules and limits.

Deploy your smart contract to the blockchain.

While auditing offers a basic layer of protection, using a DAF will give the bad guys out there a one-two knockout punch.
