+This is a fork of several repositories from https://github.com/Uniswap/
+
+All tests passed.
+
+## `main` branch
+
+Change Variable names, CREATE2 hash. But “chainId()” OPCODE call remains the same + Compiler option `istanbul` remain the same.
+
+This will NOT enable to be run on VeChain now because the EVM doesn't support it, yet.
+
+But eventually it is the unified set of code that is deployed on VeChain after the EVM support is in place.
+
+## `testnet` and `mainnet` branch
+Based on `tweak` branch.
+
+Specific tweak: “chainId” tweak (fixed value), for different branches “testnet” and “mainnet”, + Constantinpole change for Istanbul + CREATE2 hash change.
