The challenge

Atlas was scaling across multiple markets on a legacy processor that buckled under peak load, settled in a single currency, and gave their risk team no real-time visibility. Every outage meant lost merchants and a growing fraud exposure they could only review after the money had moved.

What we built

  • Re-architected the core ledger as an event-sourced service so every transaction is auditable and replayable.
  • Built a real-time fraud engine scoring each transaction in under 40ms against behavioural and velocity rules.
  • Added native multi-currency settlement with automated FX and reconciliation.
  • Deployed on autoscaling infrastructure with blue-green releases and full observability.
Lucayan didn’t just rebuild our platform — they gave our risk team a control room they never had. We onboarded three new markets the quarter after launch.
