What is Infura?
Infura is a managed blockchain infrastructure service that provides remote procedure call (RPC) endpoints and APIs for Web3 developers. Operated as a business unit within Consensys, the platform serves as the default network provider for MetaMask and routes requests across major Layer 1 and Layer 2 ecosystems.
Company background
Infura was founded in 2016 and announced publicly at Devcon2 in Shanghai before being integrated into Consensys, based in New York.
Platform architecture and supported networks
Developers access networks using JSON-RPC over HTTPS and WebSocket connections. Infura supports more than 40 networks, including Ethereum, Arbitrum, Optimism, Polygon, Linea, Starknet, Avalanche, and Palm. Alongside core EVM-compatible node access, the platform includes decentralized storage connectivity through an IPFS API and dedicated IPFS gateway. Infrastructure health is monitored via public status feeds with alert notifications distributed through webhooks, email, text message, and Slack.
Subscription tiers and pricing
Infura uses a credit-based billing system across multiple service tiers. The Core plan is free and provides 6 million credits per day with a throughput rate limit of 2,000 credits per second. Paid tiers include the Developer plan at $50 per month and the Team plan at $225 per month. Extra capacity can be added for $200 per month per 55 million credits. High-volume teams can negotiate Enterprise contracts that include custom request ceilings, dedicated account managers, 24/7 engineering support, and formal service level agreements.
Track record and infrastructure trade-offs
Operating since 2016, Infura maintains a target uptime SLA of 99.99% for its paid infrastructure. However, reliance on centralized node providers introduces systemic operational trade-offs for decentralized applications. If an upstream cloud outage or provider incident occurs, client applications and wallets routing exclusively through Infura can experience transaction processing halts and localized interface downtime unless automatic fallback RPCs are configured.

Pros and cons
Pros
- Free Core tier provides 6 million credits daily
- Direct native integration with MetaMask and Consensys tooling
- Supports over 40 blockchain networks and Layer 2s
- Target 99.99% uptime SLA on enterprise accounts
Cons
- Centralized RPC architecture creates single-point-of-failure risks
- Paid subscriptions start at $50 per month
- Strict rate limits apply on free tier throughput
Our review
4.1/5
Very good
Infura provides reliable, deeply integrated node infrastructure for the Consensys ecosystem, but users face centralized architecture dependencies and steep monthly price jumps across paid tiers.
Infura has operated since 2016 as a remote procedure call (RPC) and API node provider within Consensys. Headquartered in New York, it serves as the default node provider for the MetaMask wallet. The platform provides HTTPS and WebSocket JSON-RPC access across more than 40 networks, including Ethereum, Arbitrum, Optimism, Polygon, Starknet, Avalanche, and Linea.
The service provides reliable infrastructure with an advertised 99.99% uptime guarantee. Its incident notification system supports webhooks, email, SMS, and Slack alerts. The free Core tier grants up to 6 million credits per day, with a 2,000 credit per second throughput limit. Infura also integrates directly with the MetaMask SDK and MetaMask Snaps.
Infura has several practical trade-offs:
- Centralization risk remains a consideration. Systemic outages or service interruptions directly affect downstream applications that rely solely on its default endpoints.
- Pricing scales abruptly between tiers, jumping from free to $50 monthly for the Developer plan and $225 monthly for the Team plan.
- High-throughput custom SLAs and 24/7 dedicated engineering support require custom Enterprise agreements.
Infura suits teams deploying Web3 applications, dApps, or MetaMask Snaps that need connectivity to Ethereum and major Layer 2 networks without maintaining self-hosted hardware. Teams requiring fully decentralized infrastructure pipelines or strictly open-source node stacks may instead self-host execution and consensus clients.
