# Carbium RPC

> Sovereign Swiss RPCs for Solana developers. Carbium provides high-performance, Swiss-owned bare-metal Solana RPC nodes and unified data APIs — an alternative to shared-cloud providers like Helius, QuickNode, and Triton. Built by the team behind Spiderswap and engineered in Switzerland for speed, reliability, and transparency.

## What Carbium RPC is

- Swiss-owned, bare-metal Solana RPC nodes (not shared cloud) for serious developers, validators, and institutions.
- Unified data APIs layered on top of the RPC.
- Credit-based usage: each RPC method call consumes credits from your plan; extra credits can be purchased on top of any plan.
- Positioned as roughly 35% cheaper than Helius for comparable usage.

## Plans

- Starter — for small-scale projects.
