Estimated code review effort: 4 (Complex) | ~45 minutes Mergeability Score: 🟡 Moderate · up to The onchain metrics migration can produce near-zero volume and fee reporting when a daily balance snapshot is missing, while polling cadence remains implicit; ordinal event pairing and removal of the prior blacklist filter may also affect attribution and included volume. Merge should wait for these bounded correctness and data-quality risks to be addressed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

Handle a missing daily balance snapshot instead of treating it as zero TVL.
sum(coalesce(b.token_balance, 0)) returns 0 when solana_utils.daily_balances has no row for the day. solana_utils.daily_balances is a daily snapshot table, and the row for the current or most recent day can be absent or delayed. In that case tvlUsd becomes 0 for every pool, tvlUsd < MIN_TVL_USD is true, and volumeUsd > 0 satisfies volumeUsd > tvlUsd * MAX_VOLUME_TO_TVL. The adapter then drops all pools and reports near-zero volume and fees for that window.
Return the reserve rows as nullable and skip the low-TVL filter when the snapshot is missing, or fail the run. Do not silently report zeros.
Also, the comment states that daily windows start one second before midnight, but the expression adjusts endTimestamp. Update the comment so it describes the end boundary.

Set pullHourly explicitly on this version 2 adapter.
The adapter declares version: 2 but omits pullHourly. The repository guidelines require every version 2 adapter to set it. This adapter reads solana_utils.daily_balances, which provides one snapshot per day, and it is marked isExpensiveAdapter: true. Hourly retrieval is therefore not useful here. Set pullHourly: false and add the reason as a comment.
🔧 Proposed change
const adapter: SimpleAdapter = {
version: 2,
+ // Pool reserves come from the daily solana_utils.daily_balances snapshot,
+ // so hourly windows cannot produce a distinct TVL value for the filter.
+ pullHourly: false,

with a comment explaining that the daily solana_utils.daily_balances source
provides no useful hourly data and hourly retrieval is intentionally disabled.
Source: Coding guidelines
solana_utils.daily_balances lags chain head by about three days. Pinning the join to the window's own date found no rows on any recent run, so every pool reserve read 0, the low-TVL filter matched every pool with volume, and the adapter reported ~0 volume and fees without erroring. Clamp to the newest snapshot that is not in the future instead. Dune-backed adapters are implemented as v1 because Dune's indexers lag chain head and v1 is not eligible for hourly pulls. Verified for 2026-08-12: 83.7M USD volume, 312k USD fees, against 87.6M/362k from the current API-based adapter. With the wash-trade filters disabled the same run yields 114.8M/593k, against 124.2M/704k reported by Meteora's own API, so the underlying measurement is complete.
