Abstract

Security is the most serious topic in financial systems, especially in the decentralized and anonymous crypto world. Anything in the crypto world is INSANE! We have seen so many criminals hacking the blockchains gaining astronomical profit. Many of the rekt DeFi protocols are related to bridges, the common infrastructures that allow people to transfer digital assets between blockchains.

In this talk, I will share a few novel vulnerabilities and exploits of the Rainbow Bridge, the official bridge connecting Ethereum, Aurora and NEAR protocol. I reported one of the critical bugs, protected more than $200M funds from hacking and won the $6M bug bounty program.
