Our series on Bit2's features continues. This time: client-side smart contracts and what programmable payment logic looks like when it doesn't touch the blockchain. Most smart contracts run on every validating node. That makes computation expensive, public, and limited by network throughput. But most payment logic, like spending policies, rate limits, authorizations, conditional transfers, only involves the parties in the payment. Bit2 keeps it that way. A lightweight virtual machine lets users define programmable spending policies directly in their wallet. No third-party custody, no blockchain execution costs, no global consensus for decisions that don't require it. For autonomous agents managing funds without human supervision, this isn't optional. It's infrastructure. Latest entry in our series on the features defining Bit2, Fairgate's Bitcoin-native payment layer for the agentic economy and the world of autonomous commerce already upon us.
