01
Overview
On-chain data is public but fragmented, making wallet history and portfolio context difficult to interpret across networks.
02
Solution
A unified analysis interface that turns raw blockchain responses into understandable wallet, asset, and eligibility views.
03
Architecture
Next.js presentation layer, typed Wagmi and Viem interactions, normalized provider responses, and PostgreSQL-backed derived data.
04
System decisions
API
Provider adapters isolate chain-specific response formats.
Database
Normalized wallet snapshots separate source data from views.
UI
Provenance and confidence states distinguish facts from derived signals.
Security
Read-only wallet analysis; no custody or private keys.
Performance
Parallel requests and cached derived summaries.
05
Engineering challenges
- Normalizing inconsistent multi-chain provider responses
- Communicating uncertainty without overstating risk signals
- Keeping expensive chain requests away from critical UI paths
06
Lessons
Blockchain interfaces need strong provenance. Users should be able to distinguish source data, derived interpretation, and unavailable information.
07
Result
A unified analysis model that makes fragmented multi-chain information easier to inspect and explain.
