Vermiculus Launches VeriAct as B3 Prepares to Replace…
By Rick Steves

AI summary of the source article
Vermiculus has introduced VeriAct, a cloud-native corporate actions system designed to manage mandatory, voluntary, and complex events through configurable workflows, formulas, and tax rules rather than custom code. Brazilian exchange operator B3 is implementing VeriAct for the third phase of its central securities depository modernization, having already deployed earlier phases with Vermiculus technology. VeriAct uses a microservices architecture that allows components to scale independently and can deploy across cloud, on-premises, or hybrid environments. The platform also enables market operators to run simulations using the same deterministic logic applied to official calculations.
Why it matters
The system enables financial market infrastructures to adapt to new regulations and market practices through configuration rather than lengthy custom software projects. Deploying it at B3 tests the technology against high transaction volumes across a major central securities depository.
Key facts
- Vermiculus launched VeriAct to manage mandatory, voluntary, and non-standard corporate actions without hard-coded software updates.
- Brazilian market operator B3 is using VeriAct in the third and final phase of its cloud-native CSD transformation.
- The platform features a microservices design and runs calculations and simulations using identical underlying logic.
