Glassnode Latency Monitor — Real-Time Crypto Trading Infrastructure Latency
Live network latency from probes worldwide to crypto trading infrastructure and blockchains (Solana, SUI, Hyperliquid, Arbitrum One, Robinhood Chain, Base, X Layer). Built for traders, HFT firms, market makers, and arbitrage operators choosing where to co-locate.
What we measure
- Hyperliquid: WebSocket round-trip to api.hyperliquid.xyz via AWS CloudFront, plus direct TCP latency to Hyperliquid validator nodes in Tokyo (AZ1, AZ2, AZ4) and real order-to-fill timing.
- Solana: QUIC handshake latency to every voting Solana mainnet validator (~760 nodes), real-time leader-rotation tracking, stake-weighted best-co-location rankings, and Jito Block Engine paths across all 8 regional endpoints (Amsterdam, Frankfurt, London, Dublin, New York, Salt Lake City, Tokyo, Singapore).
- SUI: TCP+TLS handshake latency to every active SUI mainnet validator with Mysticeti consensus. Reports time-to-quorum (latency to accumulate signatures from 2/3 of stake-weighted voting power) and time-to-90% supermajority — the metrics that actually bound transaction finality on a DAG-BFT chain.
- Centralized exchanges (CEX): WebSocket and FIX latency to Binance, Coinbase, Kraken, OKX, Bybit, Bitmex, Deribit across spot, perpetuals, expiry futures, and options venues. Cross-exchange comparison mode picks the closest venue for a given product from any probe.
- Prediction markets: REST round-trip to Polymarket (clob.polymarket.com, origin AWS eu-west-2 London) and Kalshi (api.elections.kalshi.com, origin AWS us-east-2 Ohio).
- Arbitrum One: Transaction submission round-trip to the Arbitrum One sequencer (arb1-sequencer.arbitrum.io, AWS us-east-2 Ohio) — the single machine that orders every transaction on the chain. Co-location guide for Timeboost express-lane bidders and first-come-first-served flow.
- Robinhood Chain: Transaction submission round-trip to the Robinhood Chain sequencer (sequencer.mainnet.chain.robinhood.com, AWS us-east-2 Ohio) — Robinhood's Arbitrum-stack L2 for tokenized stocks and real-world assets. Ordering is strictly first-come-first-served with no fee-based priority, so distance to the sequencer is queue position.
- Base: Transaction submission round-trip to the Base sequencer (mainnet-sequencer.base.org) — the single endpoint every Base transaction must reach, since the OP Stack has no public mempool. Ordering combines priority fee and arrival time, and a later-arriving transaction cannot buy its way into an earlier Flashblock, so network distance decides which 200ms Flashblock a transaction lands in.
- X Layer: Transaction submission round-trip to X Layer, OKX's OP Stack Layer 2 (rpc.xlayer.tech) — the OP Stack has no public mempool, so every transaction must reach the sequencer to be included. Blocks are produced roughly every second, and arrival time decides which block a transaction lands in.
- HFT oracle gateways: Pyth Pro/Lazer (Tokyo bare metal), Switchboard Crossbar (GCP eu-west4), Chainlink Data Streams (Cloudflare US). Co-location guide for trading on oracle-dependent prices.
Why infrastructure location matters
For trading firms racing to be first into a price move, physical distance to exchange matching engines and blockchain validators dominates total latency. A server in the wrong city can lose by tens to hundreds of milliseconds — enough to lose every arbitrage and MEV opportunity to better-located competitors. This site publishes the actual measured numbers, continuously, so operators can make data-driven hosting decisions instead of guessing.
Probe infrastructure
Probes deployed worldwide across Asia (Tokyo multi-AZ, Seoul, Hong Kong, Singapore), Europe (Amsterdam, Dublin, London, Frankfurt), the Americas (Ashburn, Ohio, Chicago, San Jose, São Paulo), and Oceania/Africa (Sydney, Johannesburg). Probes run on Fly.io and AWS bare-metal instances.
