Uniswap V2 Fork

Credits

This is a fork of several repositories from https://github.com/Uniswap/

All tests passed.

For Developers

/uniswap-lib            # util libraries
/uniswap-v2-core        # core contracts for assets
/uniswap-v2-periphery   # surrounding contract for user interface
make install # install dependencies.
make compile # Compile all contracts.
make test # Run all the tests.

Branches in this repo:

main branch

What is changed:

  • Change variable names of LP token symbol and name. (uniswap-v2-core/contracts/UniswapV2ERC20.sol)
  • CREATE2 hash. (uniswap-v2-periphery/contracts/libraries/UniswapV2Library.sol)

What remains:

  • chainId() OPCODE call remains the same
  • Compiler option istanbul remains 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 istanbul is in place.

Below Should NOT Be Used

testnet branch

Based on main branch.

Specific tweaks:

  • chainId() tweak (fixed value) for different network: “testnet” 0x27.
  • istanbul compiler option change to constantinpole.
  • CREATE2 hash change of respective files.
  • Test cases changes to include chainId as a parameter.

mainnet branch

Based on testnet branch

Specific tweaks:

  • chainId() tweak (fixed value) for different network: “mainnet” 0x4a.
  • Compiler change same as testnet branch.
  • CREATE2 hash change of respective files.
  • Test cases changes same as on testnet branch.
