Uniswap dynamic-fee hooks — database changes

Transforms uniswap-dynamic-fee-hooks events into database changes for the BigQuery sink (oneof indices 2200–2204, table prefix uniswap_dynamic_fee_hooks). Deploys independently of the other database changes packages.

Generated code in src/ — never edit by hand; regenerate via cd ../../autogen && yarn generate-database-changes-dynamic-fee-hooks.

See substreams-packages/CLAUDE.md for build/run/deploy conventions.

evm.uniswap.dynamic_fee_hooks.Events

Fee configuration and fee state events of the Uniswap Labs dynamic-fee v4 hooks, StablePair and VolatilePair (Uniswap/v4-hooks-public, src/stable and src/volatile). Both hooks set the LP fee per swap and per direction through beforeSwap's lpFeeOverride. These events record the inputs to that fee: the per-pool fee config, set when the pool is initialized through the hook and changed later by the hook's config manager, and VolatilePair's per-block fee state.

Matching is address-filtered: only logs emitted by the hook proxies listed in uniswap-dynamic-fee-hooks/chains.json are decoded.

Units: every *_e6 field is in pips (1e6 = 100%), the unit of a v4 pool's fee. sqrt prices are Q64.96 uint160 values written as decimal strings. pool_id is the v4 PoolId (keccak256(abi.encode(PoolKey))). It joins to the PoolManager's Initialize and Swap events.

StablePairFeeConfigUpdated

evm.uniswap.dynamic_fee_hooks.StablePairFeeConfigUpdated

StableFeeConfiguration FeeConfigUpdated(PoolId indexed poolId, StableFeeConfig feeConfig) Emitted when the config manager changes a pool's config (updateFeeConfig or batchUpdateFeeConfig). Not emitted at pool initialization.

evm.uniswap.dynamic_fee_hooks.StablePairPoolInitialized

StablePairHook PoolInitialized(PoolKey indexed poolKey, uint160 sqrtPriceX96, StableFeeConfig feeConfig) Emitted once per pool by initializePool, after PoolManager.initialize in the same transaction. The config is the pool's starting fee config.

VolatilePairFeeConfigUpdated

evm.uniswap.dynamic_fee_hooks.VolatilePairFeeConfigUpdated

VolatileFeeConfiguration FeeConfigUpdated(PoolId indexed poolId, VolatileFeeConfig feeConfig) Emitted at pool initialization (with the starting config) and whenever the config manager changes a pool's config. A config write resets the pool's fee state, so the next swap starts fresh from the pool price.

VolatilePairFeeStateUpdated

evm.uniswap.dynamic_fee_hooks.VolatilePairFeeStateUpdated

VolatilePairHook FeeStateUpdated(PoolId indexed poolId, uint40 blockNumber, uint160 sqrtPriceTopX96, uint24 askPermFeeE6, uint24 bidPermFeeE6, uint24 tempFeeE6, bool tempOnBid) Emitted on the first swap of each block in which the pool trades, when the hook writes the pool's top-of-block fee state. The state holds for the rest of the block. A swap's fee in each direction starts from the permanent fee of that side, plus temp_fee_e6 on the side temp_on_bid names, and moves within the block with the price's displacement from sqrt_price_top_x96. Ask is the oneForZero side (buying currency0), bid the zeroForOne side.

VolatilePairPoolInitialized

evm.uniswap.dynamic_fee_hooks.VolatilePairPoolInitialized

VolatilePairHook PoolInitialized(PoolKey indexed poolKey, uint160 sqrtPriceX96, VolatileFeeConfig feeConfig) Emitted once per pool by initializePool, after PoolManager.initialize in the same transaction. The same transaction also emits FeeConfigUpdated with the same config, before the PoolManager's Initialize.
