built for the colosseum hackathon. this is a devnet/localnet project, not a production payroll system.

cascade is a payroll experiment on solana. employers fund a payment stream at an hourly rate, and workers can withdraw the USDC they’ve earned so far. employers retain funding controls and emergency clawback rights.

an early version of the employer dashboard

the anchor program holds funds in PDA-derived vaults and calculates vesting on-chain. a next.js dashboard handles the employer and worker flows, while postgres stores off-chain state.

the part i found interesting was keeping those two views in agreement. a transaction can succeed on-chain while the database write fails. we used idempotent reconciliation workers with checkpoints, so a worker can resume without starting over or applying the same change twice.

i built this with praxzy while learning how solana programs fit together.
