Sei RPC endpoints live on GetBlock

As one of the leading providers of blockchain connectivity, GetBlock continually expands its supported networks. 

Today, we’re announcing a new addition to our growing lineup: Sei blockchain, now available on both Shared and Dedicated Node services.

This integration allows developers and businesses access reliable RPC endpoints for the Sei Mainnet through GetBlock's proven infrastructure. 

TL;DR:

GetBlock starts providing Sei mainnet RPC endpoints and dedicated Sei node deployment services

Developers can connect to full node RPC endpoints for the Sei network over JSON-RPC and WebSocket, using GetBlock’s Shared or Dedicated node plans

Sei nodes are live in Frankfurt, New York, and Singapore for low-latency access worldwide

Sei blockchain RPC services live on GetBlock

GetBlock has launched full RPC support for Sei, an EVM powerhouse chain, giving developers fast, reliable access to the network out of the box.

GetBlock's Sei RPC services provide developers with managed access to Sei Mainnet through two service types:

Shared Nodes (ready-to-use endpoints): Access to Sei full nodes via JSON-RPC and WebSocket APIs, available starting from the free tier up to the Enterprise plan, scaling beyond 1,000 RPS.

Dedicated Nodes: Isolated full node instances with custom SLAs and unlimited throughput, tailored for production DeFi protocols, high-frequency trading platforms, and dApp infrastructures requiring consistent performance

GetBlock hosts its Sei RPC nodes in data centers located in Frankfurt, New York, and Singapore. Region parity is supported for Shared and Dedicated tiers. Users can pick any of these availability zones, regardless of plan, routing traffic to the closest node for minimal latency.

50k free daily CUs included for all signed-in users. Further scaling is available directly from the dashboard. Explore our tiered plans tailored to varying performance needs.

Scale with Dedicated Sei Nodes

GetBlock's dashboard enables self-service deployment of Sei nodes on private, isolated servers. 

Deploying a Sei blockchain node

To deploy a dedicated Sei node, follow these steps:

1

Access the Dedicated Node dashboard with your account

2

Configure the node: Select client parameters, hosting region, enable the APIs you need

3

Confirm the plan and request deployment

GetBlock's intuitive self-service dashboard puts control over your node in your hands. For more custom needs like advanced hardware or unique configs, submit a request via the in-dashboard support ticket or our contact form.

What is Sei Network?

Sei is a specialized Layer-1 blockchain, built around an Ethereum-compatible stack and an advanced execution engine. Its recent Sei Giga roadmap combines upgrades like Twin‑Turbo-style consensus, parallelized EVM execution, and optimized storage (SeiDB) to reach hundreds of thousands of transactions per second with confirmation times in milliseconds. 

Sei's architecture powers a diverse ecosystem of applications focused on performance-critical use cases. The network hosts high-frequency trading platforms that require ultra-fast order execution, decentralized exchanges with near-instant finality, and NFT marketplaces demanding low-cost minting and rapid transfers. Additionally, Sei supports Web3 gaming projects.

GetBlock powers builders on Sei

For high-frequency apps, it is not enough that the chain is fast on paper; the RPC layer also has to keep up. GetBlock’s globally distributed Sei node infrastructure is tuned for production trading volumes and responsive consumer products.
