Vaultline
Multi-chain digital asset management platform.
Challenge
Vaultline users held assets across five networks and three wallets with no single view of positions or history. Portfolio tracking meant five tabs and a spreadsheet.
Solution
We built a multi-chain balance aggregator with wallet abstraction and a normalized transaction timeline — one dashboard, every network, plain-language activity.
Architecture
Unified balance layer aggregating custodial and non-custodial accounts, a multi-chain relayer normalizing confirmations and gas, and a notification pipeline for price and movement alerts.
Features
- Unified portfolio view
- Multi-wallet connect
- Normalized transaction timeline
- Price and movement alerts
