Hey everyone,
Composable reasoning and formal verification feel increasingly relevant as Web3 projects grow more complex and modular. With ecosystems now spanning L1 chains, L2 rollups, cross-chain bridges, off-chain computation, and middleware services, it is no longer enough to test components in isolation. The real challenge lies in verifying how all of these modules interact and ensuring that assumptions hold true across boundaries. This is where formal verification could add enormous value.
Developers already use approaches like symbolic execution, model checking, and even theorem proving in specific cases, but these techniques are often siloed within single smart contracts or protocols. What seems missing is a practical way to integrate formal methods into modular, composable development pipelines. For example, how can we prove that an off-chain computation verified by ZK proofs aligns with assumptions in a DeFi lending contract? Or how can cross-chain liquidity protocols formally guarantee safety properties across different execution environments?
There is also the question of trade-offs. Full formal verification can be time-consuming and expensive, while lightweight approaches may not cover enough ground. Sharing frameworks, tools, or workflows that balance rigor with development speed could be key. I am curious whether anyone here is experimenting with integrating formal verification into composable stacks.
