DeFi Bots Series — Part 8: The Monitor Test Saga (Making the Monitor Debuggable)
I debugged the PnL, refactored the messy code we left implemented in our last devlog and made everything more compact and debuggable.

I stress-tested a one-sided, USDC-anchored LP strategy overnight: ~15 rebalances, lots of fee accrual, a few bugs, and a clearer picture of what to fix next. We tightened pool orientation, made SOL/WSOL funding sane, added skew gates (TVL/fees), and wrote proper lineage + flows. The monitor is quieter—until it needs not to be.

I moved position funding and settlements to a USDC base, fixed a sneaky PnL bug (price/mint orientation), taught the monitor to chill (cooldown + “in-range = HOLD”), and battle-tested open/close scripts with ledgered flows. It’s finally… boring—in the good way.

I rewired RPC handling with role-based profiles, unified LP strategy controls, fixed PnL accounting, and executed a live one-sided rebalance on a PUMP/USDC DLMM pool over gRPC—end to end with Supabase ledgering.

Before we let the monitor act on positions, we hardened the boring bits: one source of truth for decimals, fast prices, safe BigInt math, and clean balance reads. The goal is simple: trustworthy PnL so alerts and actions are correct.

I stripped our Telegram surface down to a fast, durable “Lite” mode: no Kafka, no AI agent in the middle—just clean wallet UX, on-chain balances via RPC, token prices from Jupiter, PnL wired to Supabase, and buttons that actually do something. This sets the table for the trading scheduler.

We wire a minimal orchestrator with a primed LP-copy scanner and a policy-driven monitor that runs in dry-run, notifies via Telegram, reads positions from Supabase, and calls execution logic via imports (no gRPC).

We build a robust scanner that reads a leader’s recent transactions and extracts DLMM position inits as (poolAddress, positionPda) intents — no brittle bin-array decoding, just clean signals my scheduler can act on.

Kicking off a new series: revive the old defi_server stack I built at Taigo, drop a new bot/ module on top, and ship a scheduler that can copy-trade Meteora LPs — with PnL tracked and later expanded to memecoins, xStocks, and perps.
