Most of the interesting financial software being built today no longer fits cleanly into one paradigm. The reliability that institutions demand — uptime, audit trails, regulatory readiness — comes most easily from cloud-native banking architecture. The composability that founders want — settlement assurance, interoperability, programmable money — comes most easily from decentralized protocols. We call the discipline of engineering across both Convergent Finance.
What stays Web2
Critical reliability surfaces remain on traditional rails. Treasury position. Customer accounts. Regulator-facing reporting. Any path where uptime SLAs and end-to-end ownership of failure modes are non-negotiable, we keep on the cloud-native side of the seam.
What becomes Web3
Composability surfaces benefit from decentralized protocols: cross-platform settlement, atomic asset movement, programmable on-chain controls. When the value comes from being able to plug into other systems without bilateral integrations, we move that surface to a protocol.
The seam is the discipline
The most consequential engineering decision in a Convergent Finance system is where the seam sits. Too far toward Web2 and you lose composability. Too far toward Web3 and you ship a system your operators cannot operate. The seam is rarely a single API — it is a set of guarantees about settlement finality, custody, and reconciliation that both sides agree to honor.
- Settlement finality: deterministic on both sides of the seam.
- Custody: explicit, with documented control transitions.
- Reconciliation: continuous, not end-of-day, and instrumented from day one.
Get the seam right and the rest follows. Get it wrong and no amount of either Web2 reliability or Web3 composability rescues the system.
