Once Upon

Open a tab, paste an address or token symbol, and get a clear narrative of what happened on-chain—who moved value, where it flowed, and why it matters. Once Upon turns raw transactions into timelines you can scan in seconds. Start by entering a wallet, ENS name, contract, or project keyword. Pick the networks you care about, then drill into transfers, interactions, counterparties, and fees with plain-language labels. Add your own tags, notes, and groups to cluster related wallets. Save a view, set an alert, and you’ve built a living brief that updates as new activity lands.

For research, portfolio tracking, or growth work, build watchlists that mirror your priorities. Example: Create a board for a protocol launch. Add the core team wallets, the treasury, key market makers, and top community whales. Track liquidity adds, token emissions, vesting unlocks, and bridge movements. Set thresholds so you’re pinged only when meaningful size moves. Export flows to CSV for modeling, or share a read-only link with your team. Need campaign attribution? Tag addresses tied to airdrop claims or referral mints and watch conversions in near real time—no dashboards to hand-craft, just filters you switch on.

Builders and analysts can trace how contracts are being used without wading through bytecode. Open an interaction, see the counterparties and assets involved, and jump to related events across blocks to understand context. Spot patterns—repeat bots, arbitrage loops, or address clusters acting in concert. Investigations move faster: label mixers or high-risk bridges, highlight sanctions-exposed entities, and exclude them from reports. Use notes to record hypotheses and link evidence across addresses so teammates can pick up the thread later.

Automate your routine. Ask in everyday language—“Show recent large swaps into token X across mainnet and Arbitrum”—and refine with filters and saved searches. Schedule a daily digest for your most important lists, routed to email, Slack, or Discord via webhooks. Build lightweight dashboards to brief leadership: top movers, net flows, new contract interactions, and unusual activity at a glance. When you’re ready to ship insights, export charts and tables or pull structured data through the API. With multi-chain coverage, natural-language views, and collaborative spaces, Once Upon streamlines how you look up, monitor, and explain everything happening on-chain.
