Consensus
Every read goes to three independent node operators. If they disagree, the figure is withheld — not guessed.

03 · ONTOLOGY
Ask in objects, not tables.
Every block is decoded into fourteen object types and the links between them. You work with a wallet, an entity, a pool — never a join. Pick coverage from Source; we run the pipelines.

04 · PROOF
Don't trust the dashboard. Trace it.
Most analytics ask you to believe a number. Voltfin shows its working — and shows you when sources disagree. The figures below are the hero read, at its pinned block.
Reconciliation
Supply read from contract state is checked against an independent third-party figure. Drift is shown, not smoothed away.
DefiLlama’s figure loads after the page…
Lineage
Each figure links to its call, contract and block range — one click from any screen.
Pinned, so it can't drift
Every read names its block by hash. A reorg can't quietly rewrite a number: the receipt fails re-verification instead.

07 · FAQ
Questions, answered plainly.
- What is a receipt?
- A receipt is the record behind one number: the source, the chain, the block number and hash, the exact call or query, who agreed on the answer, and when it was read. It is sealed with a sha256 hash, so any change to the record shows. Click any number on this page to open its receipt.
- Why do sources disagree?
- Mostly definitions. One source counts a token's total supply, another subtracts the issuer's pre-minted treasury or blacklisted balances, a third adds bridged copies. Voltfin reads contract state at a pinned block and writes each step down, so you can see which definition a number uses and where two figures part ways.
- Is Voltfin free?
- Yes. Studio is free to use today, and opening or re-checking a receipt stays free on every plan. A Pro plan is proposed for heavier research and is not on sale yet.
- Which chains?
- 6 chains are read live today: Ethereum, Base, Arbitrum One, OP Mainnet, Polygon PoS, Tron. Every read goes to independent node operators, and a figure is withheld when they disagree.
- How fresh is the data?
- The figures on this page are read from finalized blocks, and each one shows its block number and time. The hero read is refreshed every couple of minutes; the use-case cards every few minutes. Daily and hourly history arrives with Ground.
- Can I use the data?
- Chain-derived values carry their call and block, so anyone can re-run them against any node and get the same answer. Third-party figures are shown with attribution and load in your browser from their source. Terms of use for Voltfin's published datasets are being finalized.
