High-Performance Blockchain Infrastructure

A Solana RPC (Remote Procedure Call) endpoint is how your app reads from and writes to the Solana blockchain, fetching accounts, sending transactions, and streaming data. Public endpoints are shared and aggressively rate-limited, so they slow down or drop requests under load. A dedicated RPC like Carbium gives your app consistent low latency and throughput it never shares with anyone else.

Yes. Carbium's Free plan costs $0 and is ideal for testing and small experiments. When you're ready for production traffic you can move up to Developer ($32/mo), Business ($320/mo), Professional ($640/mo), or a custom Enterprise plan, without changing a line of your integration.

Carbium runs on Swiss-owned bare-metal servers instead of shared cloud connections. Because the hardware isn't rented or split across thousands of users, you get more predictable latency, higher throughput, and far fewer rate-limit errors than public or multi-tenant cloud RPCs, especially during network congestion.

It means Carbium owns and operates its own bare-metal hardware in Switzerland rather than reselling capacity on someone else's cloud. Swiss jurisdiction is known for strong data-privacy protection and neutrality, and owning the hardware end-to-end gives Carbium full control over performance, security, and uptime.

All four provide Solana RPC access, but Carbium's focus is sovereign, bare-metal infrastructure at flat, transparent pricing. Rather than per-request cloud billing, Carbium offers fixed monthly plans from Free up to $640/mo, plus Enterprise. Compare your expected usage against those tiers in the "Carbium vs. other RPC providers" section.

Carbium targets around 50 ms response latency and 99.99% uptime. Running on dedicated bare-metal hardware keeps performance consistent under load, instead of degrading the way shared endpoints do during heavy on-chain activity.

Beyond raw RPC, Carbium offers unified data APIs. The Data API gives you enriched, ready-to-use on-chain data, tokens, accounts, and more, without building your own indexer, and the Swap API provides token-swap routing, so you can ship features faster on the same infrastructure.

Sign up, grab your endpoint URL and API key from the dashboard, and point your Solana client at it. Carbium speaks standard Solana JSON-RPC, so it works with @solana/web3.js, Anchor, and your existing tooling by swapping the endpoint URL, no other code changes needed.

Carbium uses flat monthly plans: Free ($0, for testing), Developer ($32/mo), Business ($320/mo), and Professional ($640/mo), plus a custom Enterprise tier for teams at scale. Each plan includes a monthly credit allowance, and you can add extra credits or upgrade at any time.

Credits are how Carbium meters usage, each request draws credits from your plan's monthly allowance, with heavier or more complex calls costing more than simple ones. If you run low, you can add extra credits to your current plan or upgrade to a higher tier.

Start on Free to test, move to Developer for small production projects, Business for growing apps with steady traffic, and Professional for teams running at scale. If your needs exceed Professional or you want custom limits, support or an SLA, talk to us about Enterprise.

Yes. Carbium is built for production, with 99.99% targeted uptime, dedicated bare-metal performance, and enterprise-grade security. The Professional and Enterprise plans are designed for high-traffic, team-scale workloads, with custom limits and dedicated support available on Enterprise.
