Bridged Tokens: Why One Chain's Holder List Can Mislead You
6 min read· Updated 24 October 2026
A block explorer shows the holders of one contract on one chain. Plenty of tokens exist on several chains, or have a chain of their own, and the supply on any single chain can be a fraction of the whole. Read in isolation, that chain's holder list can make a widely held asset look as if one address owns nearly all of it.
How tokens move between chains
- Lock and mint. Tokens are locked in a bridge contract on the original chain and an equal amount is minted on the destination chain. The bridge contract on the original chain then holds everything that has left, and often appears as the largest holder there.
- Burn and mint. Tokens are destroyed on one chain and created on another. Supply on each chain changes as tokens move, and no single contract holds the difference.
- Adapters and gateways. Cross-chain token standards such as LayerZero's OFT use an adapter contract on the home chain that holds locked supply, and rollups use a standard bridge or gateway contract on Ethereum that holds the tokens deposited to the rollup.
- Wrapped native coins. A coin native to its own chain may have an ERC-20 version on Ethereum. The ERC-20 holder list then describes only that wrapped portion, which may be held largely by a bridge or a reserve address.
What it does to a holder figure
If 80% of a token's Ethereum balance sits in the contract of a bridge to another chain, a naive top-10 figure on Ethereum will be at least 80%, though the coins it represents are spread across thousands of holders on the destination chain.
It also works the other way. If only 10% of a token's supply exists on the chain you are looking at, then "the top 10 hold 90%" means 90% of that 10%, which tells you little about the asset as a whole.
How to tell if you are looking at part of the supply
- Compare supplies. Take the token's total supply shown on the explorer for that contract and compare it with the total supply a data aggregator gives for the asset. If the contract has much less, the rest lives elsewhere.
- Look at the labels on the top holders. Names containing bridge, gateway, portal, predicate, OFT adapter or L1 standard bridge identify cross-chain contracts.
- Check where the asset is native. Aggregators list every chain a token exists on. If it has its own chain, the ERC-20 is a secondary representation.
How FraudCoins handles it
Bridge contracts we can identify are excluded from the top-10 figure, as are exchange, treasury, pool, staking and burn addresses. Where the contract we measure carries well under the asset's total supply, or the asset has its own chain, we still publish the reading but mark it as describing part of the supply and never flag the asset on it. Both rules are on the methodology page, and the partialSupply and supplyCoverage fields are in the open dataset.
