Indexers and analytics

Factory addresses, event topics, and attribution for Dune and DefiLlama.

Pack for Dune, DefiLlama, terminals, and launchpad registries. Attribute launches to Trancepad by Factory TokenCreated, then map per-launch curve Buy / Sell / LiquidityMigrated. Machine-readable: /indexers.json.

Registry note

Dashboards such as The Robinhood Trenches only name launchpads that appear in their hand-maintained factory registry. Unmapped Factories fall into Unclassified. Share this page (or docs/indexers.md) when requesting a named Trancepad row.

Canonical addresses (chain 4663)

Live upgradeable stack from contracts/deployments/4663.json. Factory is an EIP-1967 proxy. Confirm on Blockscout.

Attribution flow

Index Factory TokenCreated on 0x5748dBa2A15257dBf3eA2fe5C80C78DAEf6e7bda.
Store token + curve (each launch has its own BondingCurve beacon proxy).
Attribute curve Buy / Sell / LiquidityMigrated to Trancepad via that curve set.
Optional: LaunchZap ZapBuy / ZapSell for USDG curve trades; Locker PositionLocked for graduation locks.
Post-grad Uniswap V4 volume is shared infrastructure. Tag by origin Factory if you want Trancepad attribution after graduation.

Curve fees

Protocol: 50 bps (0.5%) to Treasury.
Creator: Default 50 bps, max 100 bps. Per-launch value is TokenCreated.creatorFeeBps.
Volume tip: Buy.ethIn is gross. Sell.ethOut is net; gross ≈ ethOut × 10000 / (10000 − protocol − creator bps).
