AI OTP infrastructure
Every one-time password, routed for cost and speed.
L-Chain sits in front of your carriers and decides — per message — which route delivers within your latency budget at the lowest possible price.

Three steps between your login screen and a cheaper delivery.
Connect
Point your existing send call at the L-Chain endpoint. Keep your carrier accounts — we route across them.
Constrain
Set latency ceilings and cost targets per market. No model tuning, no data science team.
Optimize
The routing model learns from every delivery receipt and rebalances traffic continuously.

Price-aware routing
Every request is scored against live carrier rates. L-Chain picks the cheapest route that still clears your latency budget — per country, per operator, per minute.
Latency budgets you set
Declare a target like “under 3s in Burkina Faso”. The model treats it as a hard constraint and only optimizes cost inside it.
Predictive failover
When a carrier starts degrading, L-Chain sees it in the delivery curve and reroutes before your users ever hit a retry.
Spend forecasting
Projected monthly OTP cost by market, with the savings each routing decision produced against your previous provider mix.
Live AI demo
Try the routing engine right here.
Set a market, a latency ceiling and a monthly volume. The model picks the cheapest compliant route instantly — no sign-up, no demo request, and the session is discarded when you close the tab.
