Learn how J Labs has helped these businesses

We built an iOS crypto wallet for Limitlex, an European digital assets exchange within four weeks. Implemented features include create wallet, export mnemonic seed, generate bitcoin addresses and sign bitcoin transactions.

Here at Hut34, we try to move quickly, building proof of concepts for various uses, and sometimes we need a little help. Peanut Butter labs got straight to the heart of the challenging technical issues we needed to address to allow our users to quickly, easily and securely manage their wallets within our application. Jan and the J Labs team are diligent, technically expert, and deliver exactly what they say they’re going to, on time. These are important and all too rare qualities to find when considering extending your tech team to contractors.

A great technical team with the proven ability to deliver cross platform wallet tech on time and on budget - highly recommended.
