MXNB Mexican peso stablecoin (Juno, Bitso)New

MXNB is a Mexican peso stablecoin issued by Juno, Bitso's stablecoin business, launched in March 2025 on Arbitrum. Business clients mint it by sending pesos over Mexico's SPEI system and redeem it to Mexican bank accounts; Bitso says reserves are pesos and cash equivalents at regulated institutions with quarterly third-party attestations. In May 2026 El Salvador's digital assets regulator CNAD authorised a Bitso entity there to issue and manage MXNB. About 47.9 million MXNB were outstanding on Arbitrum in October 2026.
