Chainstack Self-Hosted adds support for Arc, Stable, Robinhood Chain, and more

Singapore, August 15, 2026 — Chainstack, a Web3 infrastructure platform serving 100K+ developers across 70+ blockchain networks, today confirmed Chainstack Self-Hosted now supports 24 protocols. The lineup spans established networks — Ethereum, Arbitrum, Polygon, and Base — alongside Robinhood Chain and the newest payments-native additions, Arc, Stable, and XRP Ledger, and more. Self-Hosted launched with Ethereum only in May; July alone added six new networks and eleven deployment targets, nearly doubling the platform's multi-chain footprint in a single month.

What Chainstack Self-Hosted is

Getting a blockchain node running isn't the hard part — keeping it synchronized, updated, monitored, and available day after day is. Chainstack Self-Hosted lets teams run nodes on infrastructure they fully own — their own servers, their own cloud, their own data — while Chainstack handles deployment, monitoring, updates, and recovery behind the scenes. A production setup is ready in five to ten minutes, down from the two-plus weeks a team typically needs to build the same thing from scratch.

Most networks are ready to use almost immediately rather than taking days to catch up to the current state of the chain. When Robinhood Chain joined the platform in July, it shipped with that instant-ready setup already built in — the first time a chain in its family got that treatment on Self-Hosted. Customers keep their own infrastructure and their own endpoints; what changes is the operational work sitting above them: coordinated updates, monitoring, and a backup connection to Chainstack's managed service if a self-hosted node ever needs to be taken offline.

Why teams choose self-hosted over managed

Self-hosted infrastructure is the better fit for specific operational profiles:

• Regulated environments where data residency, SOC 2, or ISO 27001 scope cannot include a third-party vendor.
• High-volume workloads — trading, wallet, or exchange traffic where per-request pricing at scale exceeds a fixed hardware cost.
• Custom execution logic — tracers, forensic tooling, or MEV pipelines that need direct node access.
• In-house technical teams for whom running one more node is a small addition rather than a new skill to acquire.

Building the same setup without Chainstack typically costs a team around $6,000 upfront and $15,000 or more a year per network in engineering time, once salaries are factored in — before counting the cost of downtime when something breaks. Managed infrastructure remains the better choice for smaller teams, prototypes, and bursty traffic patterns where provisioned hardware would sit idle — which is why Chainstack continues to offer Global Nodes and Dedicated Nodes alongside Self-Hosted rather than positioning one against the other.

Availability

Chainstack Self-Hosted is available now for all 24 supported protocols. Full technical requirements and the complete list of supported networks are published in the Chainstack Self-Hosted documentation. Chainstack also operates a Model Context Protocol (MCP) server that lets developers query on-chain data and deploy nodes from Claude, Cursor, Windsurf, ChatGPT, Codex, and Gemini.
