BatchPayArc
Non-custodial bulk USDC payout tool on Arc Testnet: CSV import, simulation and gas estimates, Multicall3 batches of up to 100 payments and resumable checkpoints so nobody is paid twice.
Key Features
- Recipient rows or CSV import and export with validation and duplicate warnings
- Batches of up to 100 payments through Multicall3 aggregate3
- Simulation, gas estimate and balance re-check before every signature
- Post-transaction transfer verification, local checkpoints and history export
Architecture
Single Next.js app with no backend: React hooks drive the batch run and history while pure library modules handle batching, CSV and checkpoints.
Role / Ownership
Built the batching engine, CSV pipeline, checkpoint logic, UI and test coverage.
