v5.9Mar 26, 2026
Cadence-Aligned Data-Stale Warnings
The read-time `data-stale` warning now follows the shared hourly `sync-yield-data` cadence instead of a leftover fixed 90-minute threshold from the old half-hourly lane.
Impact snapshot
- `data-stale` now triggers after three `sync-yield-data` intervals (currently about 3 hours) instead of after a hard-coded 90 minutes
- Stablecoin detail Yield Intelligence cards no longer flag healthy hourly snapshots as stale after only one delayed publish window
- The stale-warning threshold is now derived from shared cron metadata so future cadence moves stay aligned automatically
- Methodology docs and the internal timeline now describe the cadence-aware stale-warning rule explicitly

v5.8Mar 26, 2026First-Party EUR Benchmarks and Resilient CHF Parsing
Yield benchmark fetching now sources EUR €STR from the ECB's official data API with the FRED mirror as fallback, and the CHF proxy parser now tolerates the SNB's current HTML structure instead of depending on one plain-text sentence layout.
- EUR benchmark refreshes now try the ECB Data API first and only fall back to the FRED €STR mirror when the official feed is unavailable
- CHF benchmark parsing now normalizes the SNB page to text before extracting the policy-rate sentence, avoiding breakage from harmless markup changes
- Degraded benchmark metadata now reports explicit EUR and CHF failure modes instead of collapsing first-run failures into a generic `unavailable` bucket
- Yield methodology, API examples, and source inventory now reflect the official ECB feed plus the hardened SNB proxy parser

v5.7Mar 26, 2026Safety-Reweighted PYS Curve and Shared Scoring Hydration
Pharos Yield Score now uses a steeper safety penalty curve so risky names need much larger yield spreads to outrank safe ones, and the scaling factor was retuned to keep the score range readable.
- PYS now computes yield efficiency as `apy30d / (riskPenalty ^ 1.75)` instead of dividing by a linear safety penalty
- The global `PYS_SCALING_FACTOR` increased from `5` to `8` so score distribution remains readable after the steeper safety curve
- Live `/api/yield-rankings` hydration now reuses the shared PYS scorer, removing formula drift risk between cron-time scoring and read-time safety hydration
- Leaderboard, detail-surface breakdowns, docs, and the methodology page now reference the adjusted risk penalty explicitly

v5.6Mar 26, 2026Currency-Aware Benchmarks For Excess Yield
Yield Intelligence now resolves row-level benchmark context by peg currency, using USD T-bills by default, EUR €STR when available, and a CHF SNB policy-rate proxy for Swiss-franc pegs.
- The benchmark cache now publishes a small benchmark registry instead of only a single global USD risk-free rate
- Each ranking row now exposes its selected benchmark label, rate, fallback state, and selection mode so excess-yield semantics remain explicit downstream
- Detail pages, hero chips, and yield-history charts now label excess yield against the row's actual benchmark instead of hard-coding `vs T-Bill`
- The `/yield` page now hides the single benchmark line on mixed-benchmark views and restores it only when the visible scope shares one benchmark

v5.5Mar 26, 2026Non-USD Yield Scoping and Exact-Pool Commodity Overrides
Yield Intelligence now exposes a shareable non-USD ranking scope on `/yield`, and commodity coverage can use curated exact-pool DeFiLlama venues without relaxing the generic gold/silver discovery guardrails.
- The `/yield` page now supports peg-scoped ranking views, including a `non-usd` preset that groups the live EUR, CHF, SGD, MXN, and commodity rows into one visible universe
- Tier-2 DeFiLlama ingestion now preserves exact curated non-stablecoin pool UUIDs in addition to native pool IDs and wrapper symbols
- A new exact-pool override lane can publish assets like `xaut-tether` from a named venue when the UUID, project, chain, and symbol all match and the APY/TVL quality gates pass
- Generic gold/silver auto-discovery remains disabled, preventing mixed baskets such as Multipli's RWAUSDI pool from being misclassified as single-asset commodity yield sources

v5.4Mar 26, 2026Address-First Identity, Explicit Coverage, and Publish-Consistent History
Yield resolution now matches by chain and address before symbol fallbacks, every yield-bearing asset has explicit manifest coverage or an intentional gap, and published history is bounded to the latest rankings snapshot.
- DeFiLlama discovery, variant matching, and protocol-native adapters now prefer chain+address identity and drop ambiguous symbol-only candidates instead of attaching them to the first matching coin
- Protocol-native source keys now use full chain-aware identifiers (Morpho, Pendle, Yearn, Kong, Beefy, Compound, Aave) and source-link matching understands prefixed and chain-qualified labels
- Yield manifest coverage now includes explicit price-derived fallbacks and intentional gaps, so assets like cetes-etherfuse no longer disappear from coverage reporting
- Warning heuristics and published `medianApy` now share the same TVL-weighted 30d benchmark

v5.3Mar 26, 2026Yield Infrastructure Automation
Chain-scoped Layer 3 symbol matching prevents cross-chain false positives in auto-lending discovery, variant symbol auto-scanner detects new wrapper tokens (advisory mode), and monthly yield coverage audit cron provides protocol expansion recommendations.
- Chain-scoped matching adds optional chainFilter to findBestLendingPool, derived from coin contract deployments
- Variant scanner detects sXXX/stXXX/wXXX prefix and SAVE/VAULT/EARN/STAKE suffix patterns in DL pools
- Monthly coverage audit cron (1st of month, 06:00 UTC) flags unmatched high-TVL pools and missing protocols
- Protocol recommendations classify missing protocols as high-confidence (>$10M, 3+ pools) or review-needed

v5.1Mar 24, 2026Protocol-native BIMA savings fallback for USBD
USBD now resolves through BIMA's public earn API when DeFiLlama has no usable sUSBD wrapper pool, closing the remaining native-yield coverage gap without introducing a hand-set rate.
- usbd-bima now emits a protocol-native `BIMA savings (sUSBD)` source row sourced from BIMA's published `/api/earn/pools` feed
- Yield arbitration treats protocol-owned earn APIs as curated sources rather than misclassifying them as on-chain or DeFiLlama data
- The about page and source-link registry now expose BIMA's earn surface as an official yield-source reference
