Hyperliquid Infrastructure
HyperEVM, HyperCore, and Market Data
Dwellir runs Hyperliquid nodes and turns every layer into an API. JSON-RPC, Info endpoint, order book WebSocket, gRPC streaming, archives, and peering.
How Hyperliquid Works
Hyperliquid nodes write raw protocol records to disk. Dwellir exposes the available raw feeds through gRPC, while the historical archive preserves native files for longer-term workflows. Click a file type to see a sample record.

HyperCore and HyperEVM
HyperCore
The trading layer
HyperCore runs the fully on-chain order books for perpetuals and spot markets. Every order, cancel, and fill is recorded inside a block, so the order book state can be rebuilt from node files alone. HyperBFT consensus finalizes blocks in under a second and the matching engine handles 200,000 orders per second.
HyperBFTConsensus
200kOrders per second
On-chainOrder books
The node writes seven record types: blocks with 47 documented action types, fills, order statuses, raw book diffs, miscellaneous events, TWAP statuses, and periodic state dumps. Perpetuals offer up to 40x leverage on BTC. HIP-3 adds builder-deployed perp DEXs with permissionless perpetual markets, and HIP-4 adds outcome markets. The same feeds cover both.
- Info endpoint for metadata, positions, open orders, vaults, validators, and exchange state
- Order Book WebSocket for live L2, L4, BBO, and trades from Singapore and Tokyo
- gRPC streaming for raw node feeds with replay and 14 typed market streams
- Hyperliquid Index for candles, historical fills, and HIP-4 outcome markets, with a historical order book coming soon
- Archive with native node files in S3 back to 2025-01-12
HyperEVM
The smart contract layer
HyperEVM is an Ethereum-compatible execution environment that shares HyperBFT consensus with HyperCore. It runs on chain ID 999, pays gas in HYPE, and accepts standard Solidity contracts, wallets, and tooling such as ethers.js, viem, Hardhat, and Foundry.

< 1sBlock time
HYPEGas token
Dwellir serves HyperEVM from dedicated nodes with the debug and trace namespaces enabled, so indexers and analytics can trace every call. Combine a strategy contract on HyperEVM with L1 streaming from HyperCore to react to fills and book changes in the same system.
- Standard JSON-RPC for blocks, accounts, transactions, logs, and contract calls
- debug and trace namespaces for indexers and analytics
- Dedicated nodes with unlimited RPS in a Dedicated Cluster
- Method reference with request and response examples for every method

For Node Operators
Hyperliquid Peering
Run your own hl-visor node and peer with Dwellir. A peering slot allowlists one of your node IPs on two Dwellir peers, so your node keeps a stable upstream instead of rolling the dice on public root peers.
Peering SlotOne of your node IPs allowlisted on 2 Dwellir peers
Full GossipBlocks and the full mempool, same stream Dwellir consumes
99.9% Uptime SLAMeasured per calendar month on gossip reachability
No Bandwidth ChargesFlat monthly rate, no usage or egress fees
Flat rate$500/moPer peering slot. One slot covers one node IP
Every Hyperliquid Product

Order Book WebSocket
Real-time L2, L4, BBO, and trades over WebSocket from Singapore and Tokyo. Deeper books and faster delivery than the public API.
- L2 depth up to 100 levels per side
- L4 orders with user addresses
