Anchorage Digital has expanded a custody-and-listing arrangement with Latin American crypto platform Bitso, planting the federally chartered digital asset bank at the center of stablecoin flows along the remittance corridor between the United States and Mexico.

Announced Tuesday and detailed in an official announcement, the agreement places Anchorage Digital Bank's custody beneath both sides of the corridor. MXNB, Bitso's Mexican peso stablecoin, is now custodied by the bank across six blockchains: Arbitrum, Base, Ethereum, Polygon, Avalanche, and Arc. In turn, Bitso has listed USDPT and USAT, the U.S. dollar stablecoins from payments company Western Union and stablecoin issuer Tether, both of which Anchorage issues and custodies. The companies did not disclose financial terms.

The structure gives Bitso's peso token regulated custody with a U.S. federally chartered bank while extending the reach of the Anchorage-issued dollar tokens across Bitso's platform, linking the two currencies onchain along one of the world's largest money-transfer routes. The federal charter is the load-bearing detail: Anchorage became the first federally chartered digital asset bank in the United States, a status that lets it hold tokens from rival issuers under U.S. banking oversight rather than as an unregulated service.

The target is the U.S.-Mexico remittance corridor, which moves tens of billions of dollars a year and ranks among the biggest cross-border payment flows on earth. Remittances sent home by Mexican workers abroad are a critical source of income for millions of households, and much of that money still travels over correspondent banking, wire transfers, and cash-pickup networks that are slow and costly. About 15% of corridor volume already runs through Bitso's infrastructure, meaning the majority of the corridor's money still moves over those legacy channels — the pool both companies are now positioned around.

Anchorage is betting that stablecoins, which settle onchain in seconds around the clock, will increasingly replace those legacy rails, and that doing so requires custody that is regulated and sits wherever the liquidity is.

"The US-Mexico corridor is where stablecoins stop being a thesis and start moving real money at scale," said Nathan McCauley, Anchorage's CEO and co-founder, who described the firm as "the institutional custody layer on both sides of that flow." Ben Reid, Bitso's head of stablecoin, said clients can now access the full dollar-peso corridor fully onchain, backed by a federally chartered bank.

The partnership extends a broader race to wire stablecoins into Latin America's payments plumbing. Circle recently pushed deeper into the region with a USDC settlement pilot in Colombia, part of a wider expansion into dozens of emerging markets as stablecoins go mainstream. Circle's reach touches this corridor too: Arc, the sixth network in MXNB's custody lineup, is the stablecoin-focused blockchain developed by Circle — the same company competing for the region's dollar flows.

For Anchorage, the deal builds on its deepening stablecoin footprint. The bank issues Tether's U.S.-regulated USAT stablecoin, while Bitso has been pushing its MXNB peso coin across networks such as Arbitrum. By anchoring both ends of the corridor, Anchorage is aiming to become the default custodian for any issuer or bank entering the route.
