sei rpc<\/a> access on shared and dedicated nodes, exposing Sei’s EVM, Tendermint, gRPC, and Debug interfaces on mainnet. Its partners include ChangeNOW, Trust Wallet, and Tangem, which reflects a customer base built around payments and wallets.<\/p>\n\n\n\nNetwork Coverage and Node Types.<\/strong> EVM and Tendermint APIs sit side by side, which helps teams that still read Cosmos-side state while moving their logic to EVM. The Sei page lists only mainnet, so a hosted testnet endpoint has to come from somewhere else. Archive access is confirming for Sei specifically.<\/p>\n\n\n\nPerformance and Reliability.<\/strong> Requests go through geo-balanced clusters on US and EU servers, and failover kicks in automatically when a node drops. On paid plans, throughput scales with cluster capacity; there is no fixed RPS cap. NOWNodes publishes fewer independent latency benchmarks than the larger vendors, so plan to run your own tests.<\/p>\n\n\n\nPricing and Support.<\/strong> The free Start plan lasts only one month and includes 100,000 requests at 15 RPS, with no WebSocket access. Pro costs \u20ac20 for 1 million requests, Business \u20ac200 for 30 million, and Enterprise \u20ac500 for 100 million. Every plan has a 3-minute support response target. Business overage works out to \u20ac10 per million requests, which is higher than dRPC’s flat rate.<\/p>\n\n\n\n<\/span>QuickNode<\/span><\/h2>\n\n\n\nBest for:<\/em><\/strong> teams that need Sei archive data back to genesis.<\/em><\/p>\n\n\n\nQuickNode is a US-based RPC provider focused on production workloads. It serves Sei’s Pacific-1 mainnet and Atlantic-2 testnet, with separate Sei documentation for each. Its mainnet endpoints serve archive data from genesis, which is uncommon among the providers here.<\/p>\n\n\n\n
Network Coverage and Node Types.<\/strong> QuickNode supports Sei’s EVM methods alongside Cosmos REST and Tendermint APIs, and historical Cosmos queries use a block-height header. EVM methods start at block 79123881, the Sei V2 upgrade block. The QuickNode docs warn that Cosmos SDK and CosmWasm support will be deprecated in favor of EVM-only, which limits how long Cosmos-side integrations will last on any provider.<\/p>\n\n\n\nPerformance and Reliability.<\/strong> QuickNode markets an uptime SLA and low-latency routing on its Sei page, though it doesn’t state a percentage there. Rate limits scale with the plan tier, with no single published ceiling. WebSocket subscriptions are supported for real-time events.<\/p>\n\n\n\nPricing and Support.<\/strong> Billing runs on API credits, and heavier methods consume more credits per call. Third-party trackers list paid tiers at $49 (Build) and $299 (Scale), while free-tier terms are reported inconsistently. Plan to model your method mix before choosing a tier.<\/p>\n\n\n\n<\/span>Alchemy<\/span><\/h2>\n\n\n\nBest for:<\/em><\/strong> EVM developers prototyping on Sei with a permanent free allowance.<\/em><\/p>\n\n\n\nAlchemy is a developer platform known mainly for its Ethereum tooling. It lists Sei mainnet (chain ID 1329) and testnet (chain ID 1328), and its free tier includes 30 million compute units per month. It suits Solidity teams that already use Alchemy on other EVM chains.<\/p>\n\n\n\n
Network Coverage and Node Types.<\/strong> On Sei, Alchemy supports its RPC API, Debug API, and WebSockets. Its product matrix lists Trace, Webhooks, gRPC, and the Token and NFT APIs as unavailable on Sei, and those tools are the main reason many teams pick Alchemy. Access is EVM-only, with no Tendermint endpoints.<\/p>\n\n\n\nPerformance and Reliability.<\/strong> Throughput is capped at 500 CU\/s on the free tier and 10,000 CU\/s on Pay As You Go. Signed SLAs come with the Enterprise tier. Alchemy doesn’t publish a Sei-specific uptime figure.<\/p>\n\n\n\nPricing and Support.<\/strong> Pay As You Go costs $0.45 per million CU up to 300 million, then $0.40 per million. Each method carries its own CU weight, so the real cost per request depends on which calls your app makes. Enterprise customers negotiate custom rates.<\/p>\n\n\n\n<\/span>dRPC<\/span><\/h2>\n\n\n\nBest for:<\/em><\/strong> a low-cost secondary endpoint in a two-provider setup.<\/em><\/p>\n\n\n\ndRPC routes requests across independent node operators. Its chainlist covers 130+ chains across more than 220 networks, and Sei’s official provider list includes dRPC NodeCloud. Billing is a flat rate per request, which makes dRPC the simplest provider here to budget for.<\/p>\n\n\n\n
Network Coverage and Node Types.<\/strong> Sei’s documentation describes dRPC’s offering as EVM RPC endpoints. There are no dedicated Sei nodes, though teams can self-host NodeCore, dRPC’s open-source load balancer. Check the chainlist to confirm Sei testnet and archive availability.<\/p>\n\n\n\nPerformance and Reliability.<\/strong> Paid Growth plans reach up to 5,000 RPS and carry a marketed 99.99% uptime target. The free tier allows about 100 eth_call requests per second, and dRPC can lower that to about 40 during regional demand spikes. Because traffic lands on different operators, latency varies more than with single-operator infrastructure.<\/p>\n\n\n\nPricing and Support.<\/strong> The free plan provides 210 million CU per 30 days, served only from public nodes. Growth costs $6 per million requests and accepts crypto payments. Enterprise pricing starts at around 300 million requests per month.<\/p>\n\n\n\n<\/span>Ankr<\/span><\/h2>\n\n\n\nBest for:<\/em><\/strong> teams already using Ankr credits that want Sei on the same balance.<\/em><\/p>\n\n\n\nAnkr has operated Web3 infrastructure since 2017 and now positions its node network as DePIN. It serves Sei through its Node API, including a Tendermint JSON-RPC endpoint. Sei’s developer docs name Ankr among the providers suggested for production workloads.<\/p>\n\n\n\n
Network Coverage and Node Types.<\/strong> Ankr’s Sei documentation covers EVM JSON-RPC methods, and its RPC page lists Tendermint access alongside them. Premium adds debug and trace namespaces plus WebSocket connections. Dedicated deployments are available on a quote basis.<\/p>\n\n\n\nPerformance and Reliability.<\/strong> Freemium users get 30 requests per second on the Node API, and Premium raises that to 1,500. Ankr advertises 800+ archive and full nodes across its 80+ supported chains. It doesn’t publish a Sei-specific uptime figure.<\/p>\n\n\n\nPricing and Support.<\/strong> Premium pay-as-you-go starts at $10 per 100 million API credits, and the Deal plan starts at $500 for 6 billion. A third-party review cites about 200 credits per eth_call, which makes the real cost per request much higher than the headline rate. Freemium includes community support only.<\/p>\n\n\n\n<\/span>How to Choose a Sei RPC Provider<\/span><\/h2>\n\n\n\nSei’s fast finality and its move away from Cosmos interfaces change which specs matter most. Work through these steps before signing.<\/p>\n\n\n\n
\n- Audit your interface dependencies.<\/strong> List every Cosmos REST, Tendermint, or CosmWasm call your app still makes, and plan its migration under SIP-03.<\/li>\n\n\n\n
- Model polling at Sei’s block speed.<\/strong> Polling once per block produces far more calls on Sei than on Ethereum, so use WebSocket subscriptions where possible.<\/li>\n\n\n\n
- Convert every price to cost per request.<\/strong> Apply each vendor’s method weights to your real call mix before comparing CU, credits, and flat rates.<\/li>\n\n\n\n
- Check Sei-specific coverage.<\/strong> A provider’s general feature list may not apply to Sei, as Alchemy’s Sei product matrix shows.<\/li>\n\n\n\n
- Plan a fallback endpoint.<\/strong> Sei’s documentation is direct on this point: “Public RPC endpoints should only be used for development.”<\/li>\n<\/ul>\n\n\n\n
Pilot two providers with production-representative traffic for at least a week before committing.<\/p>\n\n\n\n
