Hello 256 Blocks

If you've built on blockchain, you've probably experienced the frustration of RPC providers failing at the worst possible time. Slowdowns. Rate limits. Outages during peak traffic. Many developers end up juggling multiple providers just to keep their apps running.

We're building 256 Blocks to fix this.

What It Is

256 Blocks sits between your application and RPC providers. When you make a request, we route it to the best available provider based on current performance. If that provider fails, we automatically try the next one.

We also added a policy engine so you can control which requests are allowed. You can block certain countries, restrict specific RPC methods or whatever rules make sense for your use case.

What's Coming

We're targeting January 2026 for launch. The initial release will include:

• RPC endpoints with automatic provider failover
• True multi-region infrastructure with latency-based routing
• MCP integrations for AI workflows
• Policy engine for request control
• Dashboard for monitoring

Gas sponsorship is on the roadmap but may not make the initial release.

Who We Are

We've spent years building infrastructure at scale. Core payment systems at Checkout.com. Banking infrastructure at ClearBank. Web3 integrations for Illuvium. We've seen firsthand what happens when providers fail and how much time gets wasted building workarounds.

256 Blocks is the tool we wished existed.

Pricing

If you sign up before the end of January, you lock in early adopter pricing for any organisation that you create. After that, we'll increase prices to the desired level, but early adopters keep the lower rate for life.

Closer to launch, we'll also release more details around our affiliate program so you can get free credits for referring other developers to the platform.

We've been working on this for a while now and we're excited to finally share it. If you have questions or want to chat, reach out. We'd love to hear from you.
