Usage 💻

You can transpile your Solidity/Vyper contracts with:

warp transpile CONTRACT

To deploy the transpiled Cairo contract to Starknet use:

warp deploy CONTRACT.cairo

To invoke a public/external method use:

warp invoke --contract CONTRACT.cairo --address ADDRESS --function FUNCTION_NAME --inputs "INPUTS"

The --inputs flag requires its argument to be a string and have each value separated by a space.

You can check the status of your transaction with:

warp status TX_ID
