EthPool is a learning exercise motivated by this challenge. The goal is to write a contract (named "EthPool") that allows users to deposit and withdraw ETH from. Occasionally, a pool operator will deposit rewards (also denominated in ETH) into the pool. Rewards are distributed to depositors based on their percentage share of the pool.

1. Alice deposits 1 ETH.
2. Bob deposits 1 ETH.
3. Operator deposits 1 ETH of rewards in the pool. Since Alice and Bob both have 50% ownership of the pool, they both receive 50% of the rewards (.5 ETH).
4. Alice can withdraw 1.5 ETH and Bob can withdraw 1.5 ETH.

1. Alice deposits 1 ETH.
2. Bob deposits 3 ETH.
3. Operator deposits 1 ETH of rewards in the pool. Alice recieves .25 ETH and Bob receives .75 ETH.
4. Alice can withdraw 1.25 ETH and Bob can withdraw 3.75 ETH.

1. Clone this repo
2. Create a project on Alchemy
3. Create an API key on Etherscan

# Install git submodule dependencies
forge install

# Copy the default .env file
cp .env.default .env

# Populate .env with ETH_RPC_URL from Alchemy and PRIVATE_KEY from a testnet wallet
vim .env

# Source the .env file
source .env

# Build
forge build

# Test
forge test

# Deploy contract
forge create --rpc-url $ETH_RPC_URL --private-key $PRIVATE_KEY src/EthPool.sol:EthPool

# Verify on Etherscan
forge verify-contract --chain-id $CHAIN_ID --num-of-optimizations 200 --compiler-version $COMPILER_VERSION $CONTRACT_ADDRESS src/EthPool.sol:EthPool $ETHERSCAN_API_KEY

• [ ] Consider refactoring EthPool to not use a dynamically sized array

I'd appreciate any feedback via issues.
