Why can funds appear to disappear between blockchains?¶

Cryptocurrency funds can appear to disappear when value leaves one blockchain and reappears on another through a bridge, exchange, swap service or wrapped asset.

Avoid the dangerous assumption¶

The dangerous assumption is that the trace has ended because the original asset or address is no longer visible on the first network.

A bridge may lock or receive value on one chain and release corresponding value on another.

An exchange may receive a deposit on one network, update an internal balance and later process a withdrawal on a different network.

A swap service may convert the asset before sending the result elsewhere.

The movement may therefore create several records rather than one continuous transaction.

Investigators should preserve the source transaction hash, source and destination networks, wallet addresses, token contracts, amounts, timestamps, fees and any provider or bridge reference.

Look for timing, common wallet behaviour, provider records and smart-contract events that connect the stages.

Do not assume that equal amounts alone prove the same funds reappeared.

Fees, exchange rates, pooled balances, delays and partial conversions may change the value.

Likewise, do not assume that the same token symbol represents the same technical asset on both networks.

Where a provider is involved, internal account records may be essential.

Complex cross-chain tracing may require specialist analysis.

When reporting, distinguish the confirmed source-chain movement, destination-chain movement and the evidence linking them.

Operational takeaway¶

When funds appear to vanish, identify the bridge, exchange or swap mechanism and trace the corresponding value on the destination network rather than stopping at the first chain.
