Alien Base V3 is a stock Uniswap V3 fork on Base (factory: 0x0Fd83557b2be93617c9C1C1B6fd549401C74558C, deployed at block 7150708). Core contracts are unmodified, so this reuses the existing ethereum-uniswap-v3-logs-only WASM binary with a new YAML config. Verified via substreams run on Base mainnet: pool creation events indexed correctly for ALB/WETH and WETH/cbBTC pools with correct static attributes (fee, tick_spacing, pool_address).

Register alienbase_v3 in the protocol-testing framework: - Clone mapping to reuse ethereum-uniswap-v3-logs-only substreams - Integration test config for WETH/USDC fee-750 pool on Base - Simulation state registry (UniswapV3State) - Executor bytecode mapping (UniswapV3 executor) - Fix hardcoded "ethereum" chain key in executors_json to use dynamic chain name (affects all non-Ethereum tests) Dependencies temporarily point to feat/alienbase-v3 branches for tycho-simulation and tycho-execution. Revert to pinned tags once those PRs merge. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Moved chain_model back to its original position (a461f59). The chain_key variable stays since it replaces the hardcoded "ethereum" key so the executors JSON works for Base chain too.

I think we don't commit patches usually, for testing this is nice but we should probably try to get execution merged and use the latest tag. @dianacarvalho1 @tamaralipows what's the usual process here?

While the execution/simulation PRs are not merged, this is how it should be done to test! but yeah this needs to be changed before merging.

Agreed — will remove the [patch.crates-io] section once the execution PR (#335) is merged and update to the latest tag before merging this PR.

the execution PR link is broken. it is this one
Addresses review comment: the chain_model move was unnecessary. The chain_key variable remains as it's needed to support Base chain (replaces the hardcoded "ethereum" key in executors_json). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The generic UniswapV3 executor runtime has Ethereum's factory address baked in as an immutable, causing InvalidTarget reverts for Alienbase V3 pools on Base. Build a dedicated runtime with the correct factory (0x0Fd83557) and init code hash. All 6 execution tests now pass. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
