Founded in 2015, NODE40 was the first staking company in cryptocurrency, specializing in infrastructure for incentivized blockchain applications and peer-to-peer digital asset transactions.

There was only one problem: invoices were often paid in cryptocurrency. The founders needed to determine how to report cryptocurrency on taxes, but off-the-shelf solutions were inaccurate and lacked a verifiable audit trail.

They developed an internal application that processed transaction data and tracked performance for their own cryptocurrency portfolio compliance. Today, NODE40 offers an enterprise-grade platform for crypto protocols that helps businesses calculate precise cryptocurrency capital gains and losses by revealing what happened at every stage of a transaction.
