RoadSolSafe

Consumer Apps, Undefined

A DePIN rewards platform that turns every smartphone into a silent road-safety node: by privately crunching GPS and IMU telemetry into a tamper-proof, weekly safe-driving score, it mints claimable SPL tokens and milestone NFTs for verified low-risk behavior, gamifying the commute into an addictive “play-to-save-lives” loop that offsets the 1.3 million annual road deaths and 12 % YoY surge caused by poor accountability, flagrant violations and under-resourced enforcement—while raw data never leaves the device, device attestation and behavioral anomaly filters neutralize cheaters, and the resulting open incentive layer crowdsources safer, more efficient streets for everyone.

RugGuard - Making Solana Trading Great Again

DeFi, Consumer Apps, Infrastructure

RugGuard – Real-time private swaps, raffled loss protection, and open-source fairness. My rejection for a technical role at Trojan Trading gave me the fire to build RugGuard, a product that out-performs Trojan in speed & user experience. Over $2B was lost to rugs, frontruns, and failed trades in 2024. DeFi exposes every transaction before it executes, letting bots exploit traders and drain liquidity. RugGuard fixes this with encrypted execution, instant rollups, and verifiable fairness. RugGuard is an on-chain watchdog for trading memecoins on Solana. Backed by encrypted transactions and real-time execution, RugGuard can protect traders in high-speed frantic trading or long term investments by constantly monitoring your assets, even when you are away from your PC

We charge a 1% flat rate on all transactions and swaps, which is sent to a decentralised treasury that manages revenue allocation and redistribution airdrops to its most loyal users.
