About

What it answers, and for whom.

A lock-and-mint bridge holds tokens on their home chain and issues the same amount on another chain. If the bridge is exploited or misconfigured, it can mint copies that nothing backs. This dashboard compares, token by token, the supply minted on other chains with the balance locked on the home chain at matching blocks, then shows the gap.

A small gap is normal while transfers are in flight: a deposit is locked before it is minted, and a withdrawal is burned before it is released. The dashboard separates those pending amounts from the rest, so a gap that persists or grows stands out.

It covers canonical rollup bridges, LayerZero OFT adapters and other lock-and-mint designs for major tokens. Each comparison names both blocks and both reads, so a reader can check the backing for themselves.

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 →
  1. Minted supply is totalSupply() of each bridged representation on each chain at the last block of the day; locked supply is balanceOf the escrow, lockbox or adapter contract on the home chain at the matching block.
  2. Backing is locked supply divided by minted supply summed across chains. A ratio below one, after in-flight transfers are accounted for, is a shortfall.
  3. In-flight amounts are bridge transfers that have started but not finished: withdrawals initiated but not yet finalized, deposits locked but not yet minted and OFTSent messages without a matching OFTReceived.
  4. Burn-and-mint tokens have no escrow; for them the check matches each mint on one chain to a burn on another, and compares the cross-chain total with the issuer's supply.
  5. USD values use Chainlink feeds at the same block, and every gap is shown in token units first, so a price never hides a shortfall.

Questions

Questions people ask.

What is a bridged token?

A token on one chain that stands for a token whose home is another chain. In a lock-and-mint design the original sits in an escrow contract on the home chain while the copy circulates elsewhere, so the copy is only as good as that escrow.

What makes a bridged token unbacked?

Copies minted without a matching amount locked on the home chain. It happens when a bridge's verification is bypassed, a key is compromised or a bug lets someone mint freely. Holders of the copies then share a claim on less than they hold.

Why is there sometimes a small gap?

Bridging takes time. Deposits are locked first and minted once the message arrives; withdrawals from optimistic rollups are burned first and released only after the challenge period. The dashboard shows those in-flight amounts on their own line.

Does full backing mean a bridge is safe?

No. Backing shows that the escrow holds enough today. It says nothing about who can move the escrow, how messages are verified or whether the contracts can be upgraded; the LayerZero DVN checker and the contract upgrade tracker cover some of those risks.

Lock and mint
A bridge design that locks tokens in an escrow on the home chain and mints the same amount on another chain.
Burn and mint
A design with no escrow: tokens are burned on one chain and minted on another, so supply moves rather than being copied.
Lockbox
The escrow contract that holds home-chain tokens for an omnichain token, such as a LayerZero OFT adapter.
In-flight transfer
A bridge transfer that has started on one chain and not yet completed on the other.
