Anchorage Positions Itself as Custody Backbone of US-Mexico Stablecoin Corridor

Anchorage Digital Bank is a regulated custody provider, and Bitso is tying that infrastructure to MXNB, a peso-linked stablecoin, across multiple blockchains. The pairing sits inside a payments and remittance setting that links the United States and Mexico, where settlement and custody choices matter for how a token can move between venues. The expansion names Ethereum, Arbitrum, Base, Polygon, Avalanche, and Arc, which shows the setup is being built to work across several networks rather than a single chain.

For people using or building around MXNB, the practical change is that custody support is being organized through Anchorage rather than left to ad hoc arrangements on each chain. That can simplify how institutions handle the token across different blockchains and how they integrate it into cross-border transfer workflows between the US and Mexico. It also makes the custody layer itself a central part of the product, not just a back-office detail.

The wider issue is how much of a stablecoin corridor sits inside a small number of institutions and infrastructure providers. A setup that spans several blockchains can widen reach, but it also concentrates operational control in the custody and compliance stack that sits behind the token. For cross-border crypto payments, that is a trade-off between interoperability and dependence on a managed intermediary.

Still open is how the expanded partnership will be used in practice across the six supported chains and which parts of the US-Mexico remittance flow will rely on it first. The available details do not say when users or institutions will begin transacting through the expanded setup, or what volume Bitso and Anchorage expect to route through it. It also remains unclear whether the corridor will stay limited to MXNB or be adapted for other products later.
