Description

Halo is tracking the Wealthsimple program across payments and merchant workflows surfaces where accounts, payments, identity, commerce, and financial workflows can turn a small bug into material value at risk.

What Halo Must Prove

Halo must stay inside the public program rules and prove account, payment, customer-data, identity, or business-logic impact with reproducible evidence and no service disruption.

Halo Hunt Focus

Halo is prioritizing payments and merchant workflows, wealth, brokerage, fintech, and exploit paths that show real user, protocol, or market impact.
