Features that teams build on
From long-tail networks to agent-ready APIs, real-time webhooks, a scriptable CLI and team-wide sponsored access, the tools to power real products.
A vast catalog of networks
Spectrum runs an unusually broad catalog of chains, from Ethereum, the major L1s and every serious L2, down to app-chains, testnets and the niche, hard-to-find networks most providers never bother to support. Nodes stay in constant sync, streaming blocks and transactions to each other so you integrate once and reach all of it through one consistent interface.
- Majors, rollups & app-chains
- Testnets & emerging L2s
- Niche, hard-to-find networks
- One unified integration

APIs & SDKs for builders
A typed TypeScript SDK and a unified REST + JSON-RPC surface give you balances, tokens, NFTs, prices, DeFi data and raw node access without stitching together a dozen providers. Copy an example straight from the docs and you are querying any chain in a few lines, with caching, retries and rate-limiting handled for you.

- Unified REST + JSON-RPC
- Built for on-chain & AI agents
- Caching, retries & rate-limits

Real-time events, pushed to you
Stop polling for state changes. Spectrum decodes every block and pushes the transfers you care about, native, internal, ERC-20, ERC-721 and ERC-1155, to your endpoint the moment they are confirmed. Every delivery is HMAC-signed, retried until your endpoint answers, and flagged when a reorg means an event should be rolled back.
- Push within a block, no polling
- At-least-once delivery & replay
- Reorg-aware rollbacks
- HMAC-signed payloads

A CLI for your terminal and your agents
Install one command line and query any supported chain from the shell: blocks, gas, balances, prices, yields, NFTs, ENS and raw JSON-RPC. Output is JSON by default so it pipes straight into jq and CI scripts, with --human when you want to read it, and a machine-readable command catalog that agents can consume in a single call.
- JSON by default, --human on request
- One syntax across every chain
- Machine-readable command catalog
- Retries, caching & real exit codes

Built for organisations
Give whole teams and communities access to dedicated infrastructure without handing out raw keys. Issue access via codes, then see exactly how each user consumes your nodes, broken down by network and method, with clear analytics on traffic and spend so you can scale access confidently and keep full control of your costs.
- Sponsored access via codes
- Per-user usage monitoring
- Per-network & per-method analytics
- Dedicated node access
One API for all your on-chain data
A unified REST and JSON-RPC platform with a typed SDK: balances, tokens, NFTs, prices, DeFi, and raw node access. You don't have to figure out how to query each chain. Whether it's Substrate, EVM, Bitcoin or Cosmos, you query the same way and get one consistent response format.

Frequently asked questions
Everything you need to know about building on Spectrum. Can't find an answer?
Talk to our teamOur service is hosted in our Tier 3 data center, ensuring high availability and robust security. We provide real-time statistics, such as total requests and success rates, to give you insights into node performance.
We offer comprehensive support for all Spectrum customers, including technical assistance, regular maintenance, and updates. Our support team is available to help you with any issues or questions you may have regarding your node operations.
Our Tier 3 data center provides high availability with an uptime guarantee of 99.982%. This ensures that your blockchain nodes are operational almost all the time, minimizing the risk of downtime and disruptions.
Spectrum Nodes leverages its own infrastructure to automate VM deployment, enabling setup to begin within 48 business hours of your custom requests. While the initial process is swift, full setup time may vary based on download or syncing durations beyond our control.
Spectrum benefits your business by offering reliable and secure blockchain node management. It reduces the need for self-owned specialized hardware, lowers operational costs, and ensures your nodes are always up and running. This allows you to focus on your core business activities and innovation.
Yes, our service is highly scalable. You can easily adjust the number of nodes and choose between shared or dedicated nodes based on your business needs, ensuring you have the resources necessary to support your blockchain applications.
Security is a top priority for us. Our Tier 3 data center is equipped with advanced security measures to protect your nodes from physical and cyber threats. Additionally, we implement best practices in cybersecurity to ensure your blockchain operations remain safe and secure.
For shared nodes, Spectrum Nodes will provide you with endpoints to blockchain nodes already running on our infrastructure. As the name implies, this blockchain infrastructure is shared among several users. When it comes to dedicated nodes, Spectrum Nodes will spin up all the required node infrastructure which will be used exclusively by you. As with shared nodes, we will have backups and 24/7 monitoring in place to ensure maximum redundancy.
We can provide dedicated nodes for virtually any blockchain available, as long as the chain is public and not limited to running local nodes only. For networks to which we are relatively new, the process usually starts with a short investigation into the network and its requirements, then setting up the required infra, and finally starting the setup.
