Warp

Warp brings Solidity to StarkNet, making it possible to transpile Ethereum smart contracts to Cairo, and use them on StarkNet.

Installation :gear:

To get the dependencies:

yarn

Additionally, solc 0.8.11 must be installed and usable via 'solc' Instructions can be found at https://docs.soliditylang.org/en/v0.8.11/installing-solidity.html

Compile the project:

yarn tsc

Usage :computer:

To transpile a contract:

bin/warp transpile example_contracts/ERC20.sol

Testing

To test run warp on all example contracts:

bin/warp test

For this to work, you must be able to run

starknet-compile

Instructions to set this up can be found at https://www.cairo-lang.org/docs/quickstart.html

To examine a solidity file in unwarped AST form:

bin/warp analyse example_contracts/ERC20.sol

---New tests--- The old tests check for successfully compiling cairo code The new tests check for correctly running cairo code

First run the setup script:

tests/behaviour/setup.sh

Second, in a separate terminal, start a starknet-testnet server:

yarn testnet

then to run the tests:

yarn test
