Once Upon

Start by dropping a wallet, ENS, token symbol, or contract address into Once Upon. In seconds, you get a clean, plain‑language timeline of swaps, mints, bridges, and transfers across supported networks. Tighten the view with filters for chain, protocol, method, value range, and time. Click any row to see decoded inputs and outputs, counterparties, gas details, and related contracts—no ABI digging. Compare two wallets side‑by‑side to spot behavior patterns. Save the layout, turn it into a watchlist, and receive alerts when activity matches your rules.

If you’re tracking assets or planning entries, open a token or NFT page to see ownership changes, liquidity shifts, and concentration. Follow large holders, tag them, and set triggers for whale movements, volume spikes, pool migrations, or floor swings. For DeFi users, view positions, collateral ratios, and liquidation proximity pulled from on‑chain data. Build a custom dashboard with key charts—net inflows, top counterparties, new contract interactions—and export CSVs for your spreadsheet model.

Doing due diligence or running an investigation? Trace funds hop‑by‑hop through bridges, mixers, and exchanges with automatic labeling for known services and teams. Cluster related wallets by shared interactions and common spenders. Built‑in risk signals highlight exploit paths, sanctioned addresses, and phishing tags so you can quickly separate noise from threats. Capture your work as a shareable flow diagram or timeline report, add annotations, and collaborate with teammates in a private workspace. One click generates a public link for stakeholders who need the full context.

Builders can wire Once Upon into their stack using the API and SDK. Pull normalized, decoded events; fetch entity labels; or query historical aggregates for dashboards and bots. Set webhooks that fire on specific contract methods, threshold breaches, or new deployments to power real‑time monitoring. Analysts and creators can assemble narratives by dragging timelines, charts, and annotated transactions into a guided walkthrough, then embed that view in blogs, docs, or community updates. Educators can record step‑by‑step filters that reveal how a protocol operates from deposit to settlement, making on‑chain behavior easier to follow for any audience.
