Cross-Chain Bridge Security — How We Protect Against Hacks

Bridges have become a popular target for hackers since they usually require tokens (that should be bridged into another network) to be locked in one, or several, of their smart contracts. We have all seen how other bridges in the industry have been hacked and millions in funds stolen.

Most crypto bridges work with a minter/burn functionality, where projects must partner and grant the bridge a minter role of their token to provide bridging services. As a result, projects are exposed to a high risk of hackers minting an unlimited amount of their tokens and making them unusable. The Cross-Chain Bridge tackles this risk by using liquidity pools.

Learn more about the Cross-Chain Bridge’s security practices to protect its Pools from hackers below.

Current Procedures:

  • Follow established coding best practices, use well-proven code patterns & contract templates, and learn from mistakes others made before you.

There are also additional measures that we are not disclosing publicly to maintain a second line of defence if a hacker manages to bypass these first layers of protection. “Imagine us as an old castle (the bridge contracts), surrounded by several walls and a moat (the points/procedures listed above). Now, the black hat may have a plan of the castle (the code) & they may make it over the moat. But what happens after climbing over the wall is our secret, and we intend to keep it that way.” Daniel Bläcker, Smart Contract Developer at Cross-Chain Bridge.

The best results are achieved when many smart people work together. We, therefore, strongly encourage our investors & users with developer experience/knowledge to review our codebase here. We will reward you with BRIDGE if you find something that significantly improves our protocol! Please let us know if you see any potential for improvement.

In conclusion, our bridging protocol technology is robust and focused on user security. Due to the nature of the DeFi world, we are prepared as best we can against different attack scenarios and take protecting the Bridge very seriously. This is key to connecting the largest blockchains and offering the best experience in a multichain world. Join our community in Discord and tell us what you think!
