Multi-region Solana Sender

Kolibrio operates multiple geographically distributed Solana sender endpoints to reduce network latency and improve transaction landing speed.

By default, traffic is routed through the primary region — Amsterdam. For users submitting transactions from other parts of the world, selecting the closest Kolibrio region can reduce network latency and help transactions land faster on-chain.
