Tried out ArcFlow's public testnet and got a clear sense of what they're building. An Economic OS designed for internet-scale finance—that's the pitch. What stands out is how they're bridging programmable money with traditional financial infrastructure, which isn't exactly trivial to pull off. The execution feels solid so far, and the technical approach suggests they've thought through real-world integration challenges. If they can sustain this momentum, there's genuine potential here for the next wave of blockchain-native financial primitives. Worth keeping tabs on for anyone tracking infrastructure plays.
