Conversation
- Replace Helius enhanced API with standard getTransaction JSON-RPC - Add pump.fun, photon, bullx, gmgn (9 accounts), axiom (20 accounts), fomo - FOMO: USDC fee detection via SPL token balance diffs (FeeOwners + FeeToken) - Per-account cursors keyed as plt:feeAccount for independent pagination - v0 tx support: custom accountKey unmarshaler + loadedAddresses appended - Sort allSigs by slot before stride-sample (fixes temporal bias on Axiom 20 accounts) - Add from_cursor idempotency key to raw_counts (migration 003) - Add solana_exec_cu_samples table + InsertCUSamples/PurgeCUSamples/PurgeEvents - Materializer calls purge functions after each cycle
Parse ComputeBudget::SetComputeUnitLimit (discriminator 0x03) from tx instructions. Priority fee schedule is based on requested CU limit, not actual consumption — dividing by consumed inflates price for over-provisioned txs. Falls back to cu_consumed when the instruction is absent.
…counts - ComputeBudget disc 0x02=SetComputeUnitLimit(u32), 0x03=SetComputeUnitPrice(u64). Previous code read 0x03 as u32 → CULimit was the low 32 bits of the price, random noise. - CUPriceDeclared read directly from disc 0x03 instruction — no division, no estimation. cuPriceMicro = CUPriceDeclared; 0 when instruction absent (base fee only, not a price). - Raw counts now computed from merged+deduped allSigs, not per-account. A tx touching 2 Axiom collectors was counted twice before; now exactly once. from_cursor is a compound of all account cursors for idempotency on retry.
