🤓 Do not memorize commands. Understand them
💻 foundry — [cast call] VS [cast send]
1️⃣ cast call
・ to call a view/pure function ( non state changing function )
・ required arguments :
・ RPC URL
・ Contract Address
・ Function Name
2️⃣ cast send
・ to call a non view/pure function ( a state changing function )
・ required arguments :
・ RPC URL
・ Contract Address
・ Function Name
・ Private Key
👀 where is RPC URL ?
・ default value for RPC URL is
👀 why your Private key is plain text ?
・ it belongs to anvil. so, not important
