Market discovery and ABI
Index the token curve first and attach the migrated V3 pool only after its explicit graduation link.Relevant ABI
Launchpad architecture and AMM model
Hood.fun is a launchpad with its own bonding-curve phase followed by a Uniswap v3-style market. The custom curve bootstraps the token and measures graduation; after graduation, the linked V3 pool becomes the trading and liquidity venue. Classification: custom bonding curve before graduation, then Uniswap v3-like. The active curve uses virtual/real ETH and token reserves plus protocolTrade events; it is not a V3 pool and must not use tick or sqrtPriceX96 math. After migration, the linked pool follows V3 concentrated-liquidity semantics.
Shared with V3 after migration: token0/token1, square-root price, ticks, signed swaps, and liquidity positions. Protocol-specific before migration: virtual reserves, currentPrice, trade-fee basis points, readiness/graduation flags, and the explicit curve-to-pool link.
Price calculation
Before migration usecurrentPrice(token), scaled by 1e18, or the full virtual-reserve invariant. After migration use V3 sqrtPriceX96 with decimals in exact pool order.
Liquidity tracking
Expose virtual reserves for pricing separately from real ETH/token liquidity. Apply everyTrade post-state. After migration track the linked V3 pool without deleting curve history.
Launchpad state, bonding, and migration
Use contract progress basis points divided by 100.readyToGraduate is pending; graduated, migrated, or the explicitly linked migrated pool is terminal. Do not classify an unrelated V3 pool.
