What the dashboard will show.
The dashboard as it will open in Vantage. Each figure is named here and arrives with its receipt; until its data is published, its place stays empty.
Supply
Wrapped BTC supply by chain and token on the latest complete day.
Largest token's share
%The share of total native wrapped supply held in the largest single token, which the tile names.
Tokens tracked
countWrapped BTC tokens in the registry with a non-zero supply on at least one covered chain.
30-day change
%Change in total native wrapped supply against the same chains 30 days earlier.
Supply by chain
BTCNative wrapped supply per chain on the latest day, split by token.
Supply by custody model
BTCTotal native wrapped supply by custody model: single custodian, several custodians, threshold signers or staking protocol.
Every token on every chain
Each token on each chain with its supply, native or bridged status, issuer, custody model, holders and the issuer's published reserves where they exist.
Mints and burns
Tokens minted and burned, and how each token's supply moved.
Minted, 30 days
BTCWrapped BTC minted over the last 30 days, from Transfer events from the zero address, all tokens together.
Burned, 30 days

About
What it answers, and for whom.
The wrapped bitcoin on each EVM chain is read here from every wrapped BTC token contract at each day's last block: WBTC, cbBTC, tBTC, LBTC and the others, with each chain's total built from the tokens that make it up. It shows how much bitcoin is represented on Ethereum, Base, Arbitrum, BNB Chain and Avalanche, and which issuers stand behind it.
The tokens differ in who holds the bitcoin behind them: a single custodian, a group of custodians, a decentralized signer set or a staking protocol. The dashboard tags each token with its custody model. Where an issuer publishes its Bitcoin addresses, their balance at the same day's end is read on Bitcoin and set beside the token's supply.
Bridged copies are kept apart from native issuance. A token bridged from Ethereum to another chain is backed by tokens locked in the bridge, so adding both chains' supply would count the same bitcoin twice; the dashboard counts each bitcoin once and shows bridged copies as their own series.
Method
How it will be measured.
Every figure will be read at a block, kept with its source and its exact read, and open a receipt anyone can re-check.
How receipts work →- Supply is each token contract's totalSupply() at the last block of each UTC day on every covered chain, scaled by its decimals and kept as an exact amount.
- Each token is classed as native issuance or a bridged copy on each chain, and totals add native issuance only, so bitcoin locked in a bridge is never counted twice.
- Mints and burns are Transfer events from and to the zero address, summed by token, chain and day.
- Where an issuer publishes custody addresses on Bitcoin, their balance at the day's last Bitcoin block is shown beside the token's native supply.
- Each token's custody model comes from its issuer's own documentation, recorded with its source.

Questions
Questions people ask.
What is wrapped bitcoin?
A token on another chain that represents bitcoin held elsewhere, so bitcoin can be used in that chain's applications. Whoever holds the bitcoin, a custodian, a signer group or a protocol, mints tokens when bitcoin is deposited and burns them when it is redeemed.
What is the difference between WBTC, cbBTC and tBTC?
They differ in custody. WBTC is minted through merchants against bitcoin held by its custodians; cbBTC is issued by Coinbase against bitcoin in its custody; tBTC is backed by bitcoin held by a rotating group of signers on the Threshold network. The dashboard tags each token with its model.
Is wrapped bitcoin safe?
It carries risks that bitcoin itself does not: the custodian or signers could fail or be compromised, the token contract has admin powers and bridged copies add bridge risk. The dashboard shows each token's custody model and, where possible, its reserves, but it does not rate safety.
Why not just add up wrapped BTC on every chain?
Because some of it is the same bitcoin. When a token moves from Ethereum to another chain through a bridge, the original tokens stay locked on Ethereum and a copy is minted on the other chain. Adding both would count the locked tokens twice, so totals use native issuance and show bridged copies apart.
How much bitcoin is on Ethereum?
The dashboard's Ethereum total adds the native supply of every wrapped BTC token issued on Ethereum, read from each contract at the day's last block. It counts each token once, and the table below it shows the tokens that make it up.
- Native issuance
- Tokens minted on a chain directly by their issuer against deposited bitcoin, as opposed to copies bridged in from another chain.
- Bridged copy
- A token minted on one chain against the same token locked in a bridge on another, so it adds no new bitcoin backing.
- Custody model
- Who holds the bitcoin behind a token and how: one custodian, several custodians, a threshold signer group or a staking protocol.
- Proof of reserves
- Published custody addresses or attestations that let anyone compare the bitcoin held with the tokens issued.
