A safe place to play with smart contract.
The contract is a hands-on demo, demonstrating how you can blend blockchain with real-world info, like the ETH/USD value. Feel free to use the following command to interact with it:
cast call --rpc-url $RPC_PROVIDER --private-key $PRIVATE_KEY 0x5ecDF773A508262712A785C4233F3752bb9e7417 "getEthValueInUsd()(uint256)"It's an example of a smart contract capable of both receiving and withdrawing tokens, essentially mimicking the basic functionalities of a bank.
Balance:
cast call --rpc-url $RPC_PROVIDER --private-key $PRIVATE_KEY 0x4D1770D66b50d0128d22933DCf8FcF3a594d4eC8 "balance()(uint256)"Withdraw:
cast send --rpc-url $RPC_PROVIDER --private-key $PRIVATE_KEY 0x4D1770D66b50d0128d22933DCf8FcF3a594d4eC8 "withdraw(uint256)()" <value>Foundry is a blazing fast, portable and modular toolkit for Ethereum application development written in Rust.
Foundry consists of:
- Forge: Ethereum testing framework (like Truffle, Hardhat and DappTools).
- Cast: Swiss army knife for interacting with EVM smart contracts, sending transactions and getting chain data.
- Anvil: Local Ethereum node, akin to Ganache, Hardhat Network.
- Chisel: Fast, utilitarian, and verbose solidity REPL.
