Cross-chain tracking compares records from separate ledgers using known bridge infrastructure, route messages, assets, amounts, timing, and receiving-address behavior.
Start at the source deposit
The analyst identifies the source transaction, bridge or router, input representation, amount, sender, and block time.
Understand the route mechanism
Lock-and-mint, burn-and-mint, liquidity networks, and provider-mediated delivery expose different messages and contract events. The token representation can identify the path.
Find destination candidates
Settlement windows, output amounts after fees, known delivery contracts, and message identifiers narrow possible receipts. Batching can make one-to-one matching less direct.
Follow representations, not tickers
The same ticker can refer to different contracts, native assets, or bridge wrappers. Researchers should verify the source contract or mint and the exact destination representation. A burn on one chain and mint on another produces a different evidence trail from lock-and-release or inventory-based delivery.
Build a two-column timeline
List source events and destination events in block order, converting timestamps only after retaining the original chain data. Add expected confirmation and settlement windows, provider contracts, fees, and messages. This prevents a visually close timestamp from being treated as stronger evidence than it is.
Assess confidence
An explicit cross-chain message is stronger than timing alone. Responsible analysis reports which evidence is deterministic and which is inferred.
How to read the evidence
A cross-chain review should create two evidence lists: what the source ledger records and what the destination ledger records. Then add the bridge or provider mechanism connecting them. Different address formats and execution models change the investigation, but they do not remove the endpoints. Timing and amount matches deserve cautious language unless a message, contract field, or provider record supplies a direct connection.
