On-chain data
The protocol’s relevant events (wBTC deposits, EVA burns, vault balances, circulating supply) are public transactions or states on Arbitrum. Since the contracts are immutable, the records are permanent.
For that reason, the data shown on the site, on the dashboard and in this documentation can be reproduced independently with a block explorer.
Independent verification
- Open the Arbiscan (address 0xA89d…902e; the full address is in Contracts).
- Under Token Holdings, check the vault’s wBTC balance. That is the numerator of the formula.
- On the EVA token contract, read totalSupply(). That is the denominator.
- Divide the first by the second. The result should match the base floor (Core) shown on the site and on the dashboard. In case of divergence, the on-chain data prevails.
- For the guaranteed floor, open the Arbiscan: the wBTC balance is under Token Holdings and, on the Read Contract tab, remainingEvaCovered() returns how many EVA the quota still covers and getBurningQuote() returns the amount paid per burn. That is the main value shown on the site.
- On the vaults’ transaction tab, check the regularity of the daily transfers (every day at 20:00 UTC, Core and Boost in the same transaction).
Provenance labels
The numbers shown on the site and in this documentation have distinct sources. Each one carries a label that identifies the source and how to verify it:
| Label | Meaning | How to check |
|---|---|---|
| On-chain | Read directly from the blockchain (balances, supply, burns). | Arbiscan, via the "Verify ↗" link next to the number. |
| Computed live | Derived from on-chain data by the formula (Burn Price, premium). | Redo the calculation with the on-chain data. |
| Live from the pool | Read from the mining pool’s public watcher (machines, production). | ViaBTC watcher, via the "Verify" links next to the number, one per farm. |
| Via Arbiscan | Read from the Arbiscan indexer (holder count). | EVA token page on Arbiscan. |
Single source of data
Every metric on the site comes from a single data source in the code, with explicit provenance. The same number appears identically on every page, and the label indicates how to verify it.
