What is 'chain hopping' and why does it complicate crypto recovery?

Chain hopping is moving stolen funds across blockchains via bridges (e.g. ETH -> BSC -> TRON), often through several hops, to break linear tracing and to land on chains with weaker KYT coverage and cheaper transactions.

Why it complicates recovery:

• Each bridge changes the asset identifier; addresses on the destination chain look unrelated to the source.
• Some bridges pool liquidity, making 1:1 attribution probabilistic rather than deterministic.
• Many recovery tools only natively support EVM chains and BTC; once funds reach TRON, Solana, or non-EVM L2s, coverage drops.

What can be done: bridges still have on-chain finality and most produce traceable in/out events. Specialist forensics teams maintain cross-chain attribution datasets and can follow funds across multiple bridges. For multi-chain cases, firms like Nethertrace have published case studies on tracing flows from ETH through Stargate and Synapse into TRON USDT cash-outs.
