LiskSplitter
Split Once. Pay Everyone.
About
The problem it solves Splitting bills or distributing payments to multiple people using cryptocurrency is often inefficient and error-prone. Users typically have to send funds one by one, manually copy wallet addresses, and pay transaction (gas) fees for each transfer. This process not only takes time but also increases costs and the risk of sending funds to the wrong address. LiskSplitter solves this problem by enabling users to send funds to multiple recipients in a single blockchain transaction. It significantly simplifies group payments, reduces transaction fees, and ensures transparency through smart contracts on the Lisk network. This makes LiskSplitter ideal for: Splitting bills among friends Distributing payments to team members Sending rewards, allowances, or shared expenses in crypto Any scenario requiring fast, secure, and efficient multi-recipient transfers
How it's made
Challenges we ran into One of the main challenges was handling multiple recipient addresses and ensuring accurate fund distribution within a single smart contract execution. Managing edge cases such as mismatched amounts, invalid addresses, and ensuring the total distributed value matched the sent amount required careful validation logic in Solidity. Another challenge was integrating the smart contract smoothly with the frontend. Synchronizing wallet interactions, handling transaction states (pending, success, failure), and providing clear user feedback took multiple iterations to refine. These challenges were overcome by: Implementing strict input validation and require checks in the smart contract Testing extensively using Hardhat on the Lisk Sepolia testnet Improving frontend UX to clearly display transaction status and errors Using Ethers.js for reliable wallet and contract interaction
