Improved blockchain analytics will turn out to be more and more vital to fight the usage of cross-chain bridges for illicit means, that are estimated to surpass $10 billion in worth by 2025.
Blockchain analytics agency Elliptic forecasts a 60% rise within the worth of illicit cryptocurrency laundered via cross-chain bridges from $4.1 billion in June 2022 to $6.5 billion subsequent yr. This determine is projected to double halfway via the last decade.
Cross-chain crime has been a serious speaking level in 2022 with over $2 billion fleeced in hacks concentrating on cross-chain bridges. Apart from these bridges and their contracts being focused, these bridges have additionally turn out to be an avenue for criminals to launder cryptocurrency. A first-rate instance is an unknown hacker shifting stolen funds from the now bankrupt FTX utilizing cross-chain bridges.
Cointelegraph unpacked the findings of analysis launched by Elliptic in correspondence with senior cryptocurrency menace analyst Arda Akartuna.
The Elliptic analyst defined that billions of {dollars} in belongings have been transferred between Bitcoin, Ethereum and different blockchains utilizing bridge providers similar to Portal, cBridge and Synapse. Decentralized cross-chain bridges provide an unregulated different to exchanges for transferring worth between blockchains.

Whereas some bridges are used legitimately, Akartuna famous that the instruments have emerged as a key facilitator in cash laundering. ‘Chain-hopping’, or shifting proceeds of crime between blockchains, has lengthy been used to evade tracing efforts by exchanging cryptocurrency belongings via decentralized or nameless exchanges.
As blockchain surveillance, enforcement and regulatory efforts have improved, criminals have turned to cross-chains to proceed laundering illicit funds:
“Decentralized cross-chain bridges present unregulated alternate options which might be being embraced by cybercriminals.”
Akartuna additionally notes that the sanctioning of cryptocurrency mixing service Twister Money has seen a shift in the way in which criminals launder cash. Decentralized exchanges, cross-chain bridges and coin swap providers have gotten a brand new technique of shifting illicit funds:
“Though the usage of these platforms is overwhelmingly professional, they facilitate cross-chain cash laundering and terrorist financing resulting from their lack of identification checks and anti-money laundering controls.”
An instance of elevated use of a cross-chain avenue for illicit means is RenBridge, which Elliptic analysis discovered to have laundered round $540 million of felony proceeds as of August 2022. In the meantime centralized exchanges, which additionally facilitate cross-chain or cross-asset swaps, are much less well-liked for illicit actors given the push for AML and identification screening/KYC options.
The rising prevalence of cross-chain bridge utilization for illicit means highlights the necessity for options or efforts to reduce felony utilization. Akartuna urged customers conduct due diligence on the providers used to hop between blockchains and tokens and be cautious of platforms related to illicit exercise.
Companies ought to make use of blockchain analytics instruments to display screen addresses and transactions and set clear threat guidelines for his or her cryptocurrency utilization. Nonetheless, there are some circumstances that merely can’t be predicted or prevented, as Akartuna defined:
“The sanctions in opposition to Twister Money is a major instance of how professional wallets could also be inadvertently tainted resulting from sudden enforcement actions, as you now have ‘pre-sanctions exercise’ which does not carry the identical threat as post-sanctions exercise.”
Current single blockchain analytics options have completed rather a lot to fight cash laundering within the cryptocurrency area however fall in need of capabilities to hint, display screen or forensically examine transactions throughout blockchains or tokens.
Because the Elliptic menace analyst highlighted, as soon as an asset ‘hops’ to a distinct blockchain, investigations turn out to be considerably extra complicated and useful resource intensive.
“The danger right here is {that a} pockets can maintain any variety of totally different belongings, and legacy blockchain options aren’t in a position to robotically hint the actions of the identical entity throughout separate chains.”
Screening the motion of funds on separate blockchains might even see some belongings flagged as sanctioned whereas others could present no threat. In principle, this might result in an alternate or pockets consumer unwittingly transacting with a sanctioned entity.
Elliptic, for instance, makes use of a proprietary analytics instrument with ‘holistic screening’ capabilities which merges present blockchains into an interconnected system. This enables for visualization and screening throughout chains to raised detect the motion of illicit funds.
