meteora: add protocol fees for volatile pools

[DaniiRix]

• Split fee_volume per pool by on-chain protocol_trade_fee: verified via getAccountInfo on one volatile and one stable DAMM v1 pool — 20% protocol / 80% LP on volatile pools, 0% / 100% LP on stable pools.
• dailyFees (gross) → dailyRevenue/dailyProtocolRevenue (protocol cut) + dailySupplySideRevenue (LP cut), using Balances + METRIC labels.
• Added methodology + breakdownMethodology for every field.

Summary by CodeRabbit

• New Features
  • Added richer Meteora pool reporting with separate daily fee, revenue, protocol revenue, and supply-side revenue figures.
  • Expanded daily metrics to distinguish between volume and multiple fee/revenue breakdowns.
• Documentation
  • Added clearer methodology details for how Meteora metrics are calculated and split.
• Bug Fixes
  • Improved validation during metric calculation to catch invalid values more reliably.

Walkthrough

The Meteora dex adapter's fetch function was updated to split fees into protocol and LP shares based on pool type (stable vs volatile), computing dailyRevenue, dailyProtocolRevenue, and dailySupplySideRevenue alongside dailyFees and dailyVolume using typed balance objects. Methodology metadata was also added to the exported configuration.

Changes

Meteora Fee Split and Metadata

Layer / File(s)	Summary
Fee-splitting fetch logic dexs/meteora/index.ts	Introduces protocolFeeRatio(poolType) (0% stable, 20% of LP fee for volatile pools), expands Pool interface with pool_type, updates accumulators (dailyVolume, grossFees, protocolFees, lpFees) with revised NaN validation, and replaces numeric return values with createBalances()/addUSDValue() typed balances for fees, revenue, protocol revenue, and supply-side revenue.
Methodology metadata and export wiring dexs/meteora/index.ts	Adds methodology and breakdownMethodology constants documenting metric derivation and fee-split rules, wired into the default export.

Estimated code review effort: 3 (Moderate) | ~20 minutes

• DefiLlama/dimension-adapters#7900: Both PRs add a methodology field and extend fetch to compute additional revenue metrics from fees.
• DefiLlama/dimension-adapters#7913: Both PRs add dailySupplySideRevenue to fetch output with associated methodology documentation, for different adapters.
• DefiLlama/dimension-adapters#7914: Both PRs split fee/revenue accounting into dailyProtocolRevenue and dailySupplySideRevenue with updated methodology metadata.

🚥 Pre-merge checks | ✅ 11 | ❌ 4

❌ Failed checks (4 warnings)

Check name	Status	Explanation	Resolution
Title check	⚠️ Warning	The title is relevant, but it does not follow the required [type] protocol-name - description format.	Rewrite it as [type] meteora - brief description, using the repository's required prefix and structure.
Pullhourly Required For Version 2	⚠️ Warning	Meteora is version 2 but its export lacks any explicit pullHourly setting, which the check requires.	Add pullHourly: true to the Meteora v2 export, or use pullHourly: false with a comment if hourly pulls are impossible.
Adapter Shape	⚠️ Warning	Meteora uses adapter:{[CHAIN.SOLANA]:{...start}} for a single chain, but the repo prefers chains:[CHAIN.SOLANA] with a top-level start in this case.	Refactor to a SimpleAdapter shape: set chains:[CHAIN.SOLANA], move start to top level, and keep fetch at top level unless per-chain config truly differs.
Methodology Keys	⚠️ Warning	dexs/meteora/index.ts uses UserFees in methodology, but the allowed methodology keys are display names like Fees/Revenue/Volume only.	Rename or remove UserFees; keep methodology keys limited to the approved dimension display names, and put the user-fee text under Fees if needed.

✅ Passed checks (11 passed)

Check name	Status	Explanation
Description check	✅ Passed	The description clearly summarizes the fee split and metadata changes, which is sufficient for an update PR.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
Linked Issues check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Out of Scope Changes check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Breakdown Methodology Check	✅ Passed	All .addUSDValue labels (SWAP_FEES, PROTOCOL_FEES, LP_FEES) have matching breakdownMethodology entries, and breakdownMethodology is exported in default.
Income Statement Compliance	✅ Passed	dailyFees is gross swap fees, dailyRevenue is protocolFees, and dailySupplySideRevenue is lpFees; grossFees = protocolFees + lpFees, so dailyRevenue = dailyFees - dailySupplySideRevenue.
Version 2 Required	✅ Passed	Meteora’s adapter export declares version: 2, so it satisfies the required format.
Dune Adapters Are Version 1	✅ Passed	PASS: dexs/meteora/index.ts uses only HTTP fetches, with no Dune helpers or TIME_RANGE macros, so the version-1 Dune rule doesn’t apply.
Income Statement Balance	✅ Passed	Meteora now splits gross fees into protocol and LP shares, so dailyFees equals dailyRevenue + dailySupplySideRevenue by construction.
Fetchoptions Usage	✅ Passed	Meteora uses fetch(options: FetchOptions), consumes options via createBalances, returns no timestamp, and doesn't use startOfDay/raw timestamp logic.
Efficiency And Error Handling	✅ Passed	PASS: The changed Meteora adapter has no getLogs/multiCall/allowNegativeValue or swallow-catch patterns, and the only new fee constant (0.2) is source-commented.
