Coinbase has launched a Bug-Bounty program of $ 5 million on Cantina, aimed at strengthening the security of its on-chain products and the base layer 2 network.
The program, that was announced On July 8, one of the largest of its kind is in web3 and is intended to identify critical vulnerabilities and to repair it in the smart Coinbase contracts. Security researchers are encouraged to submit their findings via the Cantina platform, which makes repeatable and structured assessments possible.
Each entry is assessed by experienced triagers and rewards are based on how important and serious every finding is. Coinbase has emphasized the importance of clear, usable entries that can lead to rapid resolutions.

This program is expanding in the earlier collaboration of Coinbase with Cantina, including audits of important components such as WebaHN modules, verified Polish and Nitro -Validators. These earlier assessments set the basis for a larger, open access program that now includes the smart contracts of Base and other on-chain systems.
The launch also comes at a time when security remains a top priority for Coinbase. In May the company was confronted with a controversial data breach with a bribed support staff. Instead of paying the ransom of the attackers, Coinbase has set up a $ 20 million reward fund for information that could help those responsible identify and prosecute.
The company has since taken several steps to improve internal checks and to increase the general security standards. In addition to the work with Coinbase, Cantina has emerged as an important force in web3 security.
The platform streams the assessment workflows and lowers the number of low value submissions by combining AI-driven tools with triage guided by expert. Cantina has also organized large programs such as the Bounty of $ 15.5 million from Uniswap (Uni) for version 4 of its protocol.
The new Bugbounty reflects the continuous shift from Coinbase to open cooperation with the security research community. It also extends the protection for base, the Ethereum (ETH) Layer 2 network of the company and supplements comparable efforts of Optimism (OP) to secure the OP -Stapel.
