NOWNodes

NOWNodes is a blockchain-as-a-service infrastructure provider that gives developers and enterprises on-demand access to full nodes across more than 120 blockchain networks without the cost or complexity of running their own hardware. Founded in 2019 and headquartered in Tallinn, Estonia, the company operates as part of the ChangeNOW group — the same organization behind the popular non-custodial exchange of the same name — and has grown into one of the broader multi-chain RPC markets' more widely cited options for teams that need production-grade node access across heterogeneous chains from a single account.

What NOWNodes Does

Running a blockchain node is resource-intensive: the operator must provision server capacity, stay current with client software upgrades, monitor peer health, manage disk growth for archive data, and absorb the latency cost of geographic distance from validators. NOWNodes abstracts all of that. A developer signs up, receives an API key through the dashboard, and immediately has access to RPC endpoints, WebSocket streams, and Blockbook explorer interfaces for any supported chain. The integration path is the same across all networks: authenticate with the API key as a header or query parameter, then call standard methods for that chain's protocol.

The service distinguishes between shared infrastructure — pooled nodes behind load balancers, appropriate for development, testing, and lower-volume production workloads — and dedicated nodes, which provide isolated hardware with no rate-limit contention. Both tiers are covered by the same 99.95% uptime SLA and the same monitoring layer. NOWNodes also maintains testnet endpoints alongside mainnet access, which is useful for teams iterating on smart contracts or wallet logic before committing funds to mainnet state.

Technical Architecture

NOWNodes supports three broad categories of blockchain architecture: UTXO-based chains like Bitcoin and Litecoin, EVM-compatible chains including Ethereum, Arbitrum, Optimism, Polygon, BNB Smart Chain, and zkSync, and Tendermint-based networks. The appropriate API interface varies by chain type: standard JSON-RPC for EVM and Solana, Blockbook (an open-source indexer originally developed for Trezor hardware wallets) for UTXO chains, and Tendermint RPC for Cosmos-family networks. WebSocket connections are available across major networks for teams that need real-time subscription to new blocks or mempool events.

The platform has expanded its physical infrastructure over time, most recently adding server clusters in the United States to complement the existing European footprint. Requests route through geographically optimal servers, reducing round-trip latency for North American clients. The company reports average response times around 200 milliseconds and the ability to handle more than 15,000 transactions per second across the platform.

A blockchain notification service covering more than 24 networks is on the product roadmap, with transaction confirmation alerts and failed-transaction detection as the primary use cases. MEV protection tooling and team-based access management have also been listed as upcoming features, which would extend the service beyond raw node access toward higher-level developer tooling.

Solana Support

For Solana specifically, NOWNodes provides access to both the HTTP RPC endpoint and the WSS (WebSocket Secure) mainnet endpoint. The HTTP endpoint covers the full Solana JSON-RPC method set: account queries, transaction submission, program account enumeration, slot and epoch status, block production and reward data, and the full range of simulation and preflight methods expected by wallets, dApps, and trading infrastructure. The WebSocket endpoint supports the standard Solana subscriptions — account change notifications, program subscriptions, log streaming, and slot notifications — which are necessary for latency-sensitive applications like arbitrage bots, liquidation monitors, and real-time portfolio dashboards.

Archive node access for Solana — the ability to query historical state from any slot rather than only the recent window retained by standard RPC nodes — is listed as a near-term addition to the platform. This matters for analytics products, tax tools, and protocols that need to reconstruct historical account state or verify ledger continuity.

Pricing and Access

NOWNodes operates a tiered pricing model. The free START plan provides 100,000 API requests per month with no credit card required, which covers light development and prototyping. Paid shared-node plans begin around €20 per month and scale with request volume and rate-per-second allowances. Dedicated Solana nodes carry a higher price point commensurate with isolated provisioning and guaranteed throughput — third-party sources cite $2,700 per month for single dedicated nodes and $5,400 per month for cluster solutions, plus a one-time setup fee, though pricing should be confirmed directly with the vendor.

Enterprise and partner tiers include custom SLAs, Service Quality Standards documentation, and direct support channel access.

Clients and Ecosystem Position

NOWNodes does not specialize in any single chain — its value proposition is breadth. Teams building multi-chain wallets, cross-chain bridges, or portfolio aggregators benefit from consolidating node access under one vendor and one billing relationship rather than managing multiple chain-specific providers. Among the clients that have publicly acknowledged using NOWNodes infrastructure are Trust Wallet, Exodus, CEX.IO, Tangem, BitPanda, and CoinGate.

The most notable recent partnership is with TradingView, announced in July 2026. TradingView integrated NOWNodes as the underlying blockchain data infrastructure for its onchain markets product, citing the provider's multi-chain access and data consistency as key factors. The partnership covers Ethereum, Polygon, Arbitrum, Optimism, and PulseChain endpoints among others.

Company Context

NOWNodes operates under the ChangeNOW umbrella, which gives it access to an established compliance framework and business relationships within the broader cryptocurrency industry. The company has a business development presence led by Chief Business Development Officer Mohammad Zahwy, who has spoken publicly about the company's positioning in the infrastructure API market. The Tallinn base reflects a broader pattern of European-domiciled crypto infrastructure businesses operating globally.

Solana Ecosystem Fit

Within the Solana developer ecosystem, NOWNodes occupies a distinct position from chain-specialized providers like Helius or Triton One, which are built exclusively around Solana's architecture and offer Solana-specific enrichment layers on top of raw RPC access. NOWNodes' advantage for Solana developers is the ability to handle Solana alongside every other chain in a single integration — useful for multi-chain wallets, cross-chain dashboards, or any product that needs Solana as one network among many. Teams whose primary infrastructure need is Solana-specific and who need advanced features like enhanced transaction parsing, DAS API access for compressed NFTs, or very high request-per-second ceilings will generally find chain-specialized providers a closer fit. Teams that need reliable, broad-coverage RPC access across a diverse network portfolio and want a single vendor relationship will find NOWNodes directly relevant.

The free tier and low entry pricing also make NOWNodes accessible to early-stage projects that need to validate a multi-chain product concept before committing to a larger infrastructure budget.
