v6.1May 8, 2026
USG extended transfer coverage
Tangent USD (USG) now has extended Ethereum mint/burn tracking from its reviewed deployment block using standard ERC-20 zero-address Transfer events.
Impact Snapshot
- Adds USG to the extended mint/burn config registry with a reviewed deployment-block start bound
- Captures the initial 40.02M USG zero-address mint history plus future USG supply changes through the standard Transfer decoder
- Keeps bridge and custom-event handling unchanged; no USG bridge classifier is configured because only the Ethereum token contract is currently tracked
v6.1May 8, 2026USG extended transfer coverage
Tangent USD (USG) now has extended Ethereum mint/burn tracking from its reviewed deployment block using standard ERC-20 zero-address Transfer events.
- Adds USG to the extended mint/burn config registry with a reviewed deployment-block start bound
- Captures the initial 40.02M USG zero-address mint history plus future USG supply changes through the standard Transfer decoder

v6.0Apr 17, 2026Bridge classifier parity, LayerZero endpoint-only signal, canonical-chain gauge weighting
Bridge classification now tags both mint and burn rows for CCIP/CCTP transactions, the LayerZero classifier recognizes endpoint-only fingerprints, and the Bank Run Gauge weights coins by their tracked-chain circulating supply rather than global supply. Atomic-roundtrip detection now requires mint/burn totals to match within 0.5%, and custom-event counterparty extraction supports unindexed address parameters.
- CCIP and CCTP bridge mints now tag as `flow_type='bridge_transfer'` (previously leaked into economic mint flow for USDC, EURC, USDO, USD1, avUSD, ZCHF)
- LayerZero classifier accepts endpoint-emitter signal alone, catching Executor-only mint patterns previously missed on USDai-Arbitrum
- Bank Run Gauge weights each coin's intensity by its circulating supply on tracked-chain scope only (e.g., USDC weighted by Ethereum supply, not global $36B+ total)
- Atomic-roundtrip detection requires sum(mint) and sum(burn) to match within 0.5% — partial same-tx mix is preserved as economic flow rather than erased

v5.2Apr 14, 2026GYD retirement from active mint/burn coverage
GYD was removed from active mint/burn flow tracking after its cross-chain contract incident left the token functionally dead and moved it to the cemetery dataset.
- Mint/burn flow configs no longer scan the Ethereum GYD token after the asset moved out of the active stablecoin registry
- Public flow coverage counts and stablecoin registry totals now exclude GYD from active surfaces
- Historical rows remain in D1 if previously ingested, but current API scope is driven by the active config registry

v5.1Apr 8, 2026Canonical-chain mint/burn scope for native issuance tracking
Mint/burn coverage now follows each asset's configured issuance chain instead of assuming Ethereum-only scope, with USDai switched to native Arbitrum issuance/redemption tracking and stale non-canonical rows excluded from public aggregates.
- USDai mint/burn tracking now runs on Arbitrum as the canonical native issuance chain instead of Ethereum bridge-transfer noise
- Aggregate and per-coin APIs now read only configured `(stablecoinId, chainId)` pairs so stale historical rows on non-canonical chains do not contaminate public flow metrics
- Cron metadata, coverage helpers, status reconciliation, daily digest, and DEWS mint/burn inputs now honor chain-aware mint/burn scope
- Admin backfill auto-selection and explicit config replay now work across the configured issuance-chain set instead of Ethereum-only

v5.0Apr 8, 2026Bridge-transfer flow exclusion for omnichain tokens
Bridge-aware classification now excludes bridge-transfer mints as well as burns, starting with USDai's LayerZero OFT path, and replay/backfill runs can repair previously inserted rows.
- LayerZero OFT transfers now mark both the mint-side and burn-side event rows as `flowType='bridge_transfer'` so they drop out of counted economic-flow aggregates
- USDai's Ethereum tracker now recognizes the documented USDai OAdapter / LayerZero packet flow instead of treating equal-sized bridge mints and burns as issuance activity
- Bridge classification now runs after all parsed rows are assembled for the config chunk, so mint-side bridge rows are visible to the classifier
- Replay and backfill persistence now updates `flow_type` on existing rows, allowing post-deploy repair of previously ingested bridge-transfer noise

v4.9Mar 24, 2026Deterministic repair loops and adapter provenance disclosures
Mint/burn repair and coverage semantics were tightened through historical-first valuation repair, deterministic cleanup backlogs, aligned FTQ classification, and explicit adapter provenance on public coverage metadata.
- Historical price repair now values events from event-day `supply_history` instead of current `price_cache` snapshots
- NULL-price healing and atomic-roundtrip sweeping now use deterministic ordered backlog queries
- The daily digest now shares the same report-card-cache FTQ classification semantics as `/api/mint-burn-flows`
- Per-coin coverage now exposes `adapterKinds`, `startBlockSource`, and `startBlockConfidence` so blanket start-block defaults are visible in the API

v4.8Mar 24, 2026Ethereum coverage wave for long-tail mint/burn tracking
Mint/burn flow coverage expanded materially by restoring and adding long-tail Ethereum ERC-20 configs that can be tracked with the standard zero-address Transfer path.
- Added 40 additional Ethereum transfer-based configs for previously uncovered tracked assets
- Extended flow coverage now includes more long-tail fiat, non-USD, commodity, and yield-bearing assets where shared metadata already exposes an Ethereum contract
- Coverage scope increased from 84 contract configs / 83 stablecoin IDs to 124 contract configs / 123 stablecoin IDs while preserving the existing critical-lane set

- Pressure Shift baseline now excludes the current UTC day and uses the last 30 fully closed daily buckets

v4.5Mar 9, 2026Data quality: noise filtering, auto-heal, and activity gating
Improves flow data reliability by excluding flash-loan roundtrips from aggregation, auto-healing missing USD prices, and gating pressure shift for low-activity coins.
- Transactions containing both mint and burn for the same token (flash loans, atomic arb) are now flagged as atomic_roundtrip and excluded from all flow aggregates
- Events synced without USD price are now automatically backfilled within 48h by the sync cron
- Coins with less than $50K absolute 24h flow now return NR instead of a potentially misleading pressure shift score
- New observability counters in cron metadata: atomicRoundtripsDetected, nullPricesHealed

v2.0Mar 1, 2026ReconstructedUSDT treasury-event capture and partial-data gauge support
Coverage and scoring robustness were upgraded to capture USDT treasury mint/burn events and keep the gauge active during early-history ramp.
- Added `startBlock` per config for near-history initialization instead of scanning from genesis
- USDT now tracks `Issue` and `Redeem` events that do not emit standard `Transfer` mints/burns
- Gauge now computes from available non-null FIS inputs instead of returning null when any coin lacks sufficient history

v1.0Mar 1, 2026ReconstructedInitial Mint/Burn Flow release
Launched baseline mint/burn flow tracking, scoring primitives, and public API surfaces for aggregate and per-coin analysis.
- Introduced phase-1 contract coverage for 10 tracked stablecoins
- Shipped FIS formula, seven-band Bank Run Gauge mapping, and flight-to-quality detection thresholds
- Deployed incremental sync cron with `/api/mint-burn-flows` and `/api/mint-burn-events`
