After extended testing of our circular arb engine and a bot-tracing investigation that revealed a competitor likely running co-located infrastructure, it’s becoming clear: circular arbitrage on Solana seems very difficult to achieve with home settings — and the infrastructure investment required to compete changes the economics entirely.

A candid look at how I used AI tools — Claude Code, GitHub Copilot, and multiple frontier LLMs — as genuine development partners to build a production-grade Solana HFT trading system. What actually works, what doesn’t, and what it means for how software gets built.
Published:
A systematic validation campaign for the planner (strategy service) layer: subscribing to live arb events, converting to Jupiter swap instructions, merging two-hop route instructions into a single atomic transaction, simulation, and on-chain execution — including confirmed DEX compatibility, token ledger chaining, and the Jito bundle rate-limit wall we hit.
Published:
How we fixed silent enrichment failures in the pool-discovery service: decoding Solscan’s XOR-encoded binary API responses, implementing a preflight URL pattern for cross-origin session sharing, and replacing a fallback enricher with an alternating design that keeps both data sources continuously exercised.
Published:
Data-driven token config cleanup: disabled 9 LSTs that contributed zero arb signals across 373,000+ events, kept the 5 that matter, and expanded monitoring to 6 extra token pairs (BONK, WIF, JUP, RAY, ORCA, PYTH) via a new enabled flag system. Results to follow.
Published:
Final quality assessment of the Solana quote & scanner pipeline: 9.4M quotes across 11 test sessions, a 106.4-hour uninterrupted run with zero errors, 100% oracle coverage, and structured arbitrage signals detected from Orca Whirlpool concentrated liquidity pools across multiple DEXes.

OpenClaw isn’t just for monitoring trading bots — it’s a general-purpose AI agent gateway. I used it with Claude Code to rapidly build a China A-share stock data pipeline and TradingView-compatible charting service, then wired OpenClaw to analyse stocks and send chart summaries straight to Telegram.

How I set up OpenClaw — an AI agent gateway — to monitor and control my Solana HFT Docker services via Telegram, with strict security isolation so the AI bot can never touch private keys or wallet secrets.

Pool Discovery Service undergoes major refactoring after discovering critical liquidity calculation bugs. Architecture simplified to focus solely on discovery, comprehensive test suite validates 716 unique pools across 13 DEXes, and extensive token pair support beyond LST tokens. Production metrics confirm improvements with proper liquidity tracking and accurate pool counting.
Published:
Pool Discovery Service reaches production milestone with triangular arbitrage support (45 token pairs), completing the Quote Service Rewrite architecture. Observability reveals surprising market insights: SOL/USDT has 278B liquidity (vs SOL/USDC 226B), and forward/reverse pool discovery yields asymmetric results.

Documentation consolidation for FlatBuffers migration: From 13 scattered docs to 1 authoritative guide. Why early-stage architecture changes are critical for HFT systems, even though time-consuming. Migration still in progress - and it’s worth every minute.
