Fradium began with a simple question: what evidence should a user see before sending funds to an unfamiliar address? I led the team and worked across the full stack to turn that question into a public product spanning address analysis, canister-hosted AI, community signals, wallet touchpoints, and an explicit user decision.
The problem
Crypto users often reach transaction confirmation with fragmented context about a destination address. The most consequential decision can happen before the available evidence has become legible.
Built for
Crypto users evaluating an unfamiliar destination address
Community reporters and validators contributing address evidence
Wallet and dApp developers exploring analysis integrations
How it works
- 01
Detect the chain and prepare chain-specific evidence.
- 02
Run the embedded ONNX model through an Internet Computer canister.
- 03
Keep model output and community evidence conceptually distinct.
- 04
Render the verdict before the user cancels or explicitly confirms the action.
What I built
Led product direction, team coordination, and multidisciplinary delivery.
Worked across the web application, wallet and extension touchpoints, and canister-backed flows.
Connected risk analysis to the transaction decision instead of leaving it in a separate dashboard.
Shaped the public-beta demonstration and technical narrative.
Fradium was built by a multidisciplinary team. The WCHL result belongs to the Fradium team; this case study foregrounds the product direction and full-stack responsibilities Wildan personally led.
Key decisions
Put the risk signal inside the decision
Evidence becomes actionable when it appears at the transaction boundary.
Tradeoff: The wallet flow needs more explanation without taking final control away from the user.
Keep model and community signals distinct
A single opaque score would hide disagreement between evidence sources.
Tradeoff: Separate signals require clearer moderation and interface language.
