Bridge Tracing

This post is a practical guide to tracing assets moved via blockchain bridges. It outlines methods such as identifying chain IDs, decoding transaction input data and logs, and using timing/amount analysis to link deposits and withdrawals across chains, with examples from Synapse, Across, ThorChain, Gala, Axelar and Fixed Float; it also notes that malicious actors may abuse bridges to obfuscate stolen funds.
