The implications of Cross-Chain Bridges under MiCA. An ever increasingly multi-chain world has led to the proliferation of cross-chain bridges, a key technological innovation providing a solution for a fundamental challenge: allowing different blockchain networks to communicate and share assets.

The BCAS analysis examines how the EU’s Markets in Crypto‑Assets Regulation (MiCA) could apply to cross‑chain bridges, which allow users to move assets and data between otherwise isolated blockchains by locking or depositing tokens on a source chain and issuing a corresponding “wrapped” or bridged token on a destination chain. As MiCA’s core regime for stablecoins (asset‑referenced and e‑money tokens) and crypto‑asset service providers (CASPs) is phased in across the EU, the question is whether the crypto‑assets and activities involved in bridging fall inside those regulated categories. A key issue is the regulatory status of wrapped/bridged tokens. Because these tokens represent a claim on underlying assets held elsewhere, they may in some structures meet MiCA’s broad definition of an asset‑referenced token (ART), which would trigger issuer licensing, capital, reserve, and white paper obligations, unless an exemption applies or there is no identifiable issuer. At the same time, bridge operators might be viewed as CASPs providing custody (holding users’ original assets or keys) and transfer services (moving assets between addresses), in which case they would need MiCA authorisation and would be subject to prudential, organisational, conduct, and AML/KYC requirements in the EU. The article stresses that the impact will depend heavily on design: more centralised bridge architectures with identifiable operators and explicit claims on reserves are more likely to be brought within MiCA, whereas fully decentralised bridges without a discernible service provider may fall outside its scope, reflecting MiCA’s general approach to “fully decentralised” DeFi services. This creates strategic choices for bridge projects serving EU users: they may need to adjust token mechanics, governance, and custody models or prepare for full compliance, including licensing and ongoing obligations, which could raise costs but also provide greater regulatory certainty for cross‑chain infrastructure.
