PROBLEMThe Challenge
Needed to throttle abuse and confirm on-chain transactions reliably under concurrent requests, while keeping claim status observable in the UI.
SOLVEDThe Solution
Implemented contract-side cooldown/blacklist rules, reCAPTCHA + Redis rate limit/cooldown, and Bull queue processors for claim execution with confirmation polling/retry. Shipped a claim UI with address validation and transaction status checks.
Scope
A testnet faucet delivered as a contract, API, and web interface. reCAPTCHA, Redis cooldowns, and queued transaction processing limit abuse and expose claim status.
