What the table will hold.
The table as it will open in Strata. Each figure is named here and arrives with its receipt; until its data is published, its place stays empty.

About
What it answers, and for whom.
Wrapped tokens let ETH and bitcoin move as ERC-20s, and developers look up their contracts constantly: WETH to route a swap, WBTC or cbBTC to list as collateral. Many chains carry several tokens with similar names, some issued by custodians and some by bridges, and only one is the address an app means. This table lists each of them on every covered chain.
Each row names the token's issuer or bridge, how it is made and what backs it: WETH wraps ETH one for one in a contract and custodial BTC tokens are minted against bitcoin a firm holds, while bridged copies depend on a bridge. It shows decimals, which differ between wrappers, and the token's supply on the chain today, read from the contract.
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 →- Each contract comes from the token registry, built from issuer and chain documentation, and is confirmed on-chain by its name(), symbol() and decimals().
- Type is wrapper contract, custodial issue, bridged copy or cross-chain standard, with the bridge or standard named; a wrapper contract's backing is its own ETH balance.
- Supply is totalSupply() at the latest day-end block on each chain, kept per chain so that bridged copies are never added to the original.
- Where a BTC token's reserves are published as Bitcoin addresses, the reserve balance is shown beside the token's total supply across chains in the row's receipt.

Questions
Questions people ask.
What is WETH?
Wrapped ether: an ERC-20 token that holds ETH one for one. Contracts that expect ERC-20 tokens can handle WETH, and anyone can wrap or unwrap at any time through the WETH contract. On chains whose gas token is not ETH, the token called WETH is usually a bridged copy instead.
Why are there several WETH tokens on one chain?
Bridges and apps sometimes deploy their own wrapped ETH, and older bridged versions stay in circulation after a chain adopts a canonical one. The table marks the canonical contract that the chain's documentation names and lists the others with their issuers.
Why do wrapped BTC tokens use different decimals?
Each issuer chooses. WBTC and cbBTC use eight decimals, matching bitcoin's smallest unit, while tBTC and some others use eighteen like most ERC-20 tokens. An app that assumes one scale for every BTC token will misprice the others.
Is the address the same on every chain?
Sometimes. Some issuers deploy at the same address on several chains, but many do not, and a lookalike token can sit at an address that looks right on another chain. Always match the address to the chain, which is what each row does.
How can I check a wrapped token's backing?
For WETH, the contract's ETH balance should equal its supply. For custodial BTC tokens, compare the issuer's published reserve addresses on Bitcoin with the token's total supply across chains. The wrapped bitcoin supply page tracks those checks over time.
- Wrapped token
- A token that represents another asset one for one, held in a contract or by a custodian, so it can be used where the original cannot.
- Canonical token
- The version of a token that a chain or issuer names as official, usually minted by its native bridge or by the issuer.
- Custodial issue
- A token minted by a firm against assets it holds in custody, redeemable through that firm.
