PUNTA MITA, Nayarit, Mexico — October 26, 2026 — ArcadiaB, Mexico's longest-running Bitcoin financial services company, and AnchorWatch, the U.S. Bitcoin custody and insurance company, today announced a partnership to offer Multi-Institutional Custody (MIC) in Mexico through CustoBia, ArcadiaB's new custody brand.
The partnership was announced live at MITA TechTalks 2026, an invite-only gathering of executives and family offices focused on Bitcoin, AI and energy.
Under the partnership, CustoBia clients' Bitcoin will be secured in multi-signature vaults whose keys are held by independent institutions in different jurisdictions, including ArcadiaB in Mexico and AnchorWatch Trust Company, a Nevada-chartered qualified custodian, in the United States.
No single company, and no single country, can move a client's Bitcoin alone. Eligible clients will also be able to add insurance backed by A+ rated Lloyd's of London syndicates through AnchorWatch.
Multi-Institutional Custody has emerged as a best practice for safeguarding significant Bitcoin holdings.
It removes the single points of failure common in traditional custody, including a single company's insolvency, operational error, insider fraud or legal jurisdiction. AnchorWatch already operates this model with partners in the United States and Europe. CustoBia will be its first partner in Mexico and Latin America.
"Until now, Mexican investors and companies have had very few credible, certified options to safeguard their Bitcoin," said José Carlos Flores, CEO of ArcadiaB, adding, "With CustoBia, we are bringing institutional-grade custody to Mexico, built on the best practices of Multi-Institutional Custody.”
“AnchorWatch is one of the most trusted Bitcoin custodians in the United States and globally, and partnering with them gives our clients something new in this market: territorial diversification and insured protection, without giving up the local service and regulatory knowledge of a Mexican company."
"We have been eager to serve Mexican clients, and see Mexico as one of the most important Bitcoin markets in the Americas," said Becca Rubenfeld, co-founder and COO of AnchorWatch.
"By partnering with ArcadiaB, we can support multi-institution custody in the Mexican market and be part of the first true multi-jurisdictional custody solution. This model meets the needs of serious Bitcoin holders in Mexico, effectively mitigating the risk vectors that put wealth at risk. We're proud to serve Mexican families and businesses through CustoBia."
CustoBia's Multi-Institutional Custody service will be available to individuals, companies and family offices in Mexico starting January 2027. More information is available at custobia.com.
