Astralane

Astralane is a Solana infrastructure company that provides low-latency transaction sending, raw shred data delivery, and historical on-chain data indexing for high-frequency traders, automated bots, and protocol builders who cannot tolerate execution delays.

What Astralane Does

Founded in 2024 and based in Toronto, Canada, Astralane describes itself as "low latency middleware for high frequency operations." The platform handles the infrastructure layer that sits between a trading system and the Solana network—routing transactions through the most effective validator pathways, delivering block data as early as possible during propagation, and providing indexed access to historical and real-time chain state.

The company targets a specific market: participants for whom milliseconds are material. That includes MEV searchers, arbitrageurs, market makers, prediction-market bots, and institutional-grade trading desks. Astralane's products are designed to replace the ad-hoc combination of self-managed RPC nodes, Jito bundles, and data indexers that most sophisticated traders currently stitch together themselves.

Iris: The Transaction Sending Engine

Astralane's flagship product is Iris, a transaction sender built for Solana mainnet. Iris is available directly through Astralane's API and also listed on the QuickNode marketplace, where it launched in October 2025.

Iris achieves p90 sub-slot latency—meaning 90% of transactions land within one slot of submission—by combining three mechanisms: validator co-location at key geographic nodes, leader-schedule awareness so transactions are routed just before the relevant validator is scheduled to produce a block, and multi-pathway routing across SWQoS clients (including Jito and Paladin) and direct connections to block builders such as Harmonic and BAM. Custom schedulers like Rakurai are also supported.

The API exposes four transaction submission methods:

• sendTransaction — Single transaction submission routed through the full network of pathways. Requires a minimum tip of 10,000 lamports. Supports optional MEV protection and an swqos-only mode.
• sendBundle — Atomic execution of up to four sequential transactions. If any transaction in the bundle fails, the entire bundle reverts, preventing partial fills. MEV protection is available via Jito control accounts.
• sendIdeal — Designed for traders using durable nonces. Accepts two parallel transaction variants—one fee-prioritized, one tip-prioritized—and automatically cancels the redundant transaction once one settles. Astralane manages nonce accounts per API key.
• sendBatch — Submits up to 25 transactions simultaneously, returning signatures in submission order. Useful for high-throughput bot operations.

MEV protection across all methods works by checking the current Solana leader against a curated list of validators flagged as unsafe. If the leader is on the list, the transaction is held and deferred until a trusted leader takes over.

Iris is available on QuickNode in three subscription tiers: Starter at $249 per month (10 requests per second), Scale at $499 per month (20 RPS), and Pro at $749 per month (40 RPS). Enterprise custom pricing is available on request. An open-source beta client, iris-rs, is available on GitHub.

Shreds: Pre-Reconstruction Block Data

The shreds service delivers raw UDP streams of Solana block data directly to subscribers. On Solana, blocks are never transmitted as complete units—they are split into small packets called shreds and broadcast across the Turbine fan-out network. Validators reconstruct the full block from these shreds at different times depending on their network position, and the gap between when a leader finalizes a block and when a given node reconstructs it is where latency advantages are won or lost.

Astralane sources shreds from multiple validator-direct feeds, delivering them to subscribers before full network propagation completes. Even a few milliseconds of advance data access translates into earlier knowledge of account state changes and orderbook movements—a meaningful edge in competitive MEV or arbitrage environments.

The shreds service uses a tip-based access model tied to trailing 24-hour on-chain tips: Tier 1 (0.2 SOL in tips) covers development and testing access; Tier 2 (0.5 SOL) enables ultra-low-latency production feeds with broader validator coverage. Regional infrastructure currently runs in Frankfurt (Fra2) and New York (Ewr2).

Data Infrastructure

Beyond transaction execution, Astralane offers historical and real-time data infrastructure for developers who need to query or stream on-chain events at scale. Solana's throughput creates extreme data volumes—at 50,000-65,000 TPS, the ledger accumulates roughly 100 TB per year, and full historical state is measured in petabytes. Standard indexing approaches face several compounding problems: WASM execution limitations, RPC node log truncation (1 KB per entry), gRPC streaming bottlenecks under high subscription loads, and query latency that spikes by 300% during congestion.

Astralane's data layer uses tiered storage—hot data in Postgres, cold data in Clickhouse—and integrates with providers like Triton's Old Faithful for ledger access. The platform supports petabyte-scale historical traversal and real-time streaming with millisecond latency, along with a custom SDK for enriching external data pipelines.

Ecosystem Position

Astralane operates in the increasingly competitive Solana infrastructure middleware space, alongside providers like Jito (the dominant bundle and MEV marketplace), BloXroute, NextBlock, and Temporal. Its differentiation centers on combining transaction sending, shred data, and indexing under a single provider, and on the technical depth of Iris's routing logic relative to simpler send-and-retry approaches.

The platform is integrated into the QuickNode marketplace, broadening access for developers already using QuickNode for RPC. Astralane also publishes Mandarin-language documentation, signaling deliberate outreach to Asian trading communities—a segment that is heavily active in Solana DeFi and bot-driven markets.

An Astralane MCP (Model Context Protocol) integration is available, allowing AI-assisted tooling to interact with Astralane's infrastructure APIs directly.

Staking

Astralane operates an on-chain staking program (program address SscQkTYV2BFQYGGffAmTzvefrFrw6z9GNYiWHstVZ77) on Solana mainnet, classified as an SPL staking service. The precise mechanics and rewards structure of this program are not detailed in available public documentation at the time of writing.
