"I highly recommend OCA. David and Aryeh are professional, reliable, and have helped us navigate the world of crypto accounting. They provided us with personalized advice, answered crypto-related questions, and gave us clear guidance on reconstructing our Master P&L. Thank you, OCA for providing exceptional service and expertise in the crypto space."

Steve McGary

CEO @ SandStorm

"Before we discovered OnChain Accounting, we were stuck with traditional accountants who couldn't make heads or tails of blockchain. They didn't even provide us with monthly financials! Transitioning to OnChain Accounting was a game-changer. Their expertise in blockchain and the monthly financial insights they provide are invaluable, and their fractional CFO service has been instrumental in shaping our financial decisions. If you're in the crypto industry and need a reliable accounting team, I wholeheartedly recommend OnChain Accounting."

Nick Calabro

Founder & CEO @Deep Lake Fi

“As a fellow CPA who has worked with Aryeh and David, I can say that they are a pleasure to work with and I look forward to continuing to work with them. They are very communicative and focused on their client’s satisfaction, and they produce quality work. I was originally recommended to them as people with a high standard of integrity, and they exceeded my expectations.”
