Regardless of whether you’ve been working in the crypto world for some time, maybe just following it after hours, or if you are thinking about co-creating the most promising branch of technology, we have wonderful news for you!
L2BEAT is an analytics and research company with a strong scientific approach, focused on the problem of blockchain scaling.
Its founders are real tech veterans with a ton of experience in DeFi and building Ethereum dev tools.
Passion for crypto, respect for the best programming practices, and ambition to thrive – thanks to those qualities L2BEAT has gained the trust of top Ethereum companies and The Ethereum Foundation, despite still being in the early stage of development.
If you choose to join us, you will be part of a team building an explorer that verifies the state of Layer Two solutions and allows the users to exit their funds in case of emergency. The first version of the tool is already live at, but we are going to extend it to multiple new systems, which requires a lot of new functionality.

you want to work on open source projects and with the respect for best programming practices (clean code, testing)
you’re eager to learn about blockchain technology or you already know something about it
What about responsibilities and tech stack:
implementing integrations with various L2 systems
building APIs and data processing subsystems
adding new functionality to the website
Typescript, Ethers.js, Yarn workspaces, Koa, PostgreSQL, React
What can we offer:
15k-25k PLN net + VAT on B2B

mentoring by engineers experienced in blockchain and Ethereum environment
