You must have the following installed on your machine:

• circom
• node and ts-node
• basic unix tools like mv, cp, rm, etc.
• save ptaus files into ./ptaus folder. Naming convention: powersOfTau28_hez_final_**.ptau, e.g., powersOfTau28_hez_final_08.ptau

For how to download ptaus files, see here.

# Example: Download ptaus file of size 14 to ./ptaus folder
wget -P ptaus https://storage.googleapis.com/zkevm/ptau/powersOfTau28_hez_final_14.ptau

First, install dependencies by pnpm install or yarn install.

Now let's setup a type. For example, let's setup a type called fancy with the following type definition:

@revocable(16);balance:uint<160>;happy:prop<8,c,1>;cool:bool;

Assuming the creator of the type is 0xd8da6bf26964af9d7eed9e03e53415d37aa96045. The output directory is ./build/fancy.

Simply run the following command:

pnpm start setup-type --name fancy --typedef "@revocable(16);balance:uint<160>;happy:prop<8,c,1>;cool:bool;" --creator "0xd8da6bf26964af9d7eed9e03e53415d37aa96045" --outputDir ./build/fancy
