MultiTokenSplitwise

This repository contains Solidity smart contracts for managing multi-token group expenses and split payments among participants. The system supports both ETH and ERC20 tokens, allowing for flexible contributions and automated settlements.

Contracts

MultiTokenSplitwise.sol

This contract facilitates the creation and management of expense splits among participants using ETH or ERC20 tokens. Key features:

• Create Expense Splits: Initiate a new split specifying the total amount, number of participants, and duration.
• Multi-Token Support: Contribute using ETH or any ERC20 token.
• Cancel or Close Splits: Cancel an ongoing split or automatically close it once contributions are complete.
• Withdraw Contributions: Participants can withdraw their contributions if the split is canceled or the deadline passes.

Usage

Deployment

1. Deploy the MultiTokenSplitwise contract on the desired blockchain.
2. Configure the contract with the appropriate settings, including token addresses and participants.

Configuration

• Use the createSplit function to initiate a new expense split.
• Participants can contribute using the contribute function.
• The initiator can cancel the split using the cancelSplit function if needed.

Functions
