BoltRPC

BoltRPC keeps expanding ! New chains, new dashboard and a new website. And the biggest update of all: WebSocket on every network we serve. Including the chains whose nodes have no subscription API at all: Aptos, Bitcoin, Sui and many more. Two weeks free, 5 million request units, no credit card required. Thank you for building with us.

Austin + Kyoto are live on Polygon Mainnet and Amoy. We upgraded our stack and wrote up what actually changed. Build on Polygon with BoltRPC → boltrpc.io (free 14-day trial)

Live since 2021, trusted by teams like Chainlink, Enjin, Tiingo and Gains Network. 20+ chains, one API key. Two weeks free trial, no credit card needed. Link in comments.

Linea is now supported on BoltRPC. 2026 is shaping up to be a year of network expansion and we’re continuing to grow the BoltRPC network stack with the addition of Linea. Linea is a production zk-EVM network designed to scale Ethereum applications while remaining fully compatible with existing tooling. As zk-based Layer 2 adoption accelerates, reliable and consistent infrastructure becomes essential. With Linea now supported, BoltRPC provides Enterprise-grade RPC access across 16+ networks, all accessible via a single API key. We welcome input as we continue to prioritize additional network support.

Starknet Juno Update ! The Starknet ecosystem continues moving fast and the latest updates to Juno, Nethermind’s Go-based Starknet full-node client are a great example of this progress. 🔧 What’s New in Juno’s Latest Release 🔧 This release introduces a new database architecture that cuts Starknet node storage from 500GB down to 200GB when paired with modern compression. Juno v0.15.18 also opens up new performance tuning controls, letting operators configure their nodes based on actual hardware, instead of one-size-fits-all defaults. With zstd compression now available (and becoming default in 0.16.0), database growth slows dramatically without CPU trade-offs. It’s an optional migration for now, but it won’t stay that way. This release reflects ongoing refinement at Starknet’s infrastructure layer. Focusing on long-term cost efficiency, performance consistency and sustainable production operations. BoltRPC provides Enterprise-grade Starknet RPC endpoints designed to scale with the network as it evolves. Start building now on Starknet with BoltRPC.

“Our RPC is fast.” That’s usually true. The real question is: fast when?

Latency isn’t a nice to have for RPC users. It directly impacts: • trading execution • oracle updates • user experience • downstream system reliability Milliseconds compound when infrastructure sits in the critical path. RPC performance is not about “fast in theory” . it’s about being fast under load.

Many teams start with free endpoints, but their workloads quickly resemble real production patterns. Traffic spikes, retries, failed calls and noisy neighbors reveal far more about an RPC provider than synthetic benchmarks ever will. This is usually the moment teams realize: RPC infrastructure isn’t something you upgrade later. It’s something that either holds under pressure or doesn’t. That difference only shows up in real usage.

Grateful to everyone who put their trust in BoltRPC this year. The teams building real products, the projects running serious infrastructure and the people pushing meaningful innovation forward in this space. This year reminded us how important solid infrastructure really is. When things scale, when markets move, when users depend on reliability. That’s when it matters most. We’re grateful for the trust, the partnerships, the conversations and the support along the way. In 2026, our focus stays simple: more reliability, stronger performance and even better support for the builders who rely on us.
