Optimism Foundation brings unified RPC access to the Superchain ecosystem, powered by Nirvana
"Working with Nirvana allows us to offer the same level of resilience at the infrastructure layer as we do at the protocol layer. Their low-latency RPC and node foundation ensures our marquee partners can build and scale reliably across the Superchain with consistency, uptime, and confidence."
SUMMARYThe Optimism Foundation (OPF) leads the development of the OP Stack, one of the most widely adopted rollup frameworks in Web3.
OPF powers networks such as Base, World Chain, and Unichain. Together, these OP Stack networks form the Superchain, a unified ecosystem of rollups that share infrastructure, contribute sequencer revenue, and scale as a cohesive network.
As the Superchain expanded, OPF identified a core need: reliable, production-grade RPC infrastructure across its network. Previously, each chain operated its own setup with a mix of self-hosted environments and third-party RPC vendors. This fragmentation made it difficult to guarantee consistent performance, uptime, and operational efficiency across the Superchain.
To solve this, OPF launched a grant program to standardize RPC delivery and provide high performance, high-availability infrastructure to key partners and applications.
PRODUCT HIGHLIGHTS
Unified RPC Endpoints for 19 OP Stack Networks
One access point instead of multiple providers, delivering consistent, production-grade performance.
High-Availability Managed Nodes (1 x Archive + 1x Full)
Active archive and full nodes provide continuous availability, geographical redundancy, and failover safety.
Foundation-Managed Rate Limiting
Rate limiting is centrally managed by the Optimism Foundation to ensure fair usage, protect critical infrastructure, and maintain consistent performance.
Nirvana's UI for unified RPC Access & API Key Management
Nirvana enables OPF to deliver reliable RPC to Superchain builders and manage API keys through a single Nirvana interface, covering onboarding, usage monitoring, and access control across 19 OP Stack networks.
Deepdive
BACKGROUNDOP Stack adoption accelerated quickly with the rise of networks like Base and Unichain, but infrastructure fragmentation threatened reliability and scale. Many OP Stack chains previously managed their own RPC endpoints and node operations, resulting in uneven performance across the ecosystem.
OPF set out to strengthen the Superchain's infrastructure layer to match its rollup ambitions by:
Delivering reliable, scalable, production-grade RPC and node access
Simplifying onboarding with a unified endpoint model, ensuring consistent performance across all OP Stack networks
Removing operational overhead from individual chains
Enabling single-key access for ecosystem partners
Nirvana Labs was selected to power the Superchain's standardized RPC and node foundation.
WHY NIRVANA?The Superchain needs infrastructure that matches its scale. Nirvana delivers fast, stable RPC through a shared, standardized node foundation with built-in failover, designed to reduce network hops and improve response times.
Running on dedicated compute with unmetered requests at a fixed monthly rate, the Superchain ecosystem gets predictable, high-performance RPC even during peak demand. Multi-datacenter redundancy, 24/7 monitoring, automated failover, and zero-downtime migrations make reliability the default.
The result is a unified, high-speed RPC foundation developers can trust - shared by design, stable at scale, and free from the operational overhead that once held OP-supported networks back.
Use Cases (Under Superchain)
Goldsky: Real-Time, Queryable Indexing at Scale
Goldsky indexes OP Stack networks in real time, powering subgraphs and fast on-chain search across the supported Superchain networks. As a long-time partner of Nirvana, Goldsky runs its Elasticsearch clusters on infrastructure alongside to OP node, giving their indexers low-latency access to fresh state, trace calls, and always-hot datasets. This gives their indexers node proximity access to fresh state, trace calls, and always-hot datasets, all inside the same high-performance bare-metal environment with no public internet hops. With Nirvana Connect, our private fiber network, Goldsky moves data locally with ultra low latency, zero egress costs, and consistent, real-time reliability even during network spikes.

Li.Fi: Faster, More Reliable Cross-Chain Execution
Li.Fi connects assets and liquidity across multiple OP Stack rollups, where RPC reliability directly shapes both the speed and safety of bridge transactions. Every leg of a cross-chain swap depends on real-time RPC responses, synchronized node state, and consistent performance across chains. With Nirvana operating the OP RPC endpoints behind Li.Fi's flows, Li.Fi gets uniform latency, predictable response times, and node level access to state across the supported networks . Regional routing, rate-limit controls, and automated failover keep execution stable even during high-volume spikes, allowing Li.Fi to deliver faster, more reliable cross-chain swaps on OP.
Superbridge: Fast, Verified Settlement Using Canonical OP Bridges
Superbridge is the official interface for moving assets across the Superchain through the Native Bridge contracts, the most secure and canonical path between OP Stack networks. Because every transfer depends on accurate chain state, finality, and sequencing, RPC performance directly determines settlement speed and correctness. By running on Nirvana's managed RPC endpoints and node layer, Superbridge always serves verified, up-to-date chain data. Redundant archive and full nodes across multiple data centers ensure high availability and consistent responses even during congestion, cloud instability, or regional outages. The result is fast, dependable settlement across OP's supported networks with the security guarantees of canonical bridging.
