Summary: ARQ is better cataloged as a LATAM stablecoin-and-cross-border-finance control plane than as a simple “digital dollar app.” The project formerly operated as DolarApp, and its current first-party materials show a broader operating stack spanning consumer balances in USDc and EURc, local top-up rails across Mexico, Colombia, Brazil, and Argentina, U.S. account details for ACH and wire transfers, card programs, and a business product with treasury hedging, bulk payouts, and corporate cards. The help-center articles are especially important here because they make the stablecoin plumbing explicit: incoming fiat funds are automatically converted into “digital dollars,” virtual-asset services in Mexico are handled by DolarApp México, and ARQ repeatedly frames stable-value balances as the bridge between local rails and global finance.
What it does:
Lets users top up from local fiat rails including SPEI, PSE, Pix, and Argentine bank-transfer rails, with automatic conversion into digital-dollar balances in several markets
Provides U.S. account details for ACH and wire transfers so users can receive dollars and have them credited as digital dollars
Offers consumer balances in USDc and EURc plus wallet-level auto-conversion settings into USDc
Runs a card product and positions itself as an everyday finance app for spending, saving, transfers, and international use
Operates a business product for startups and SMEs with treasury hedging in digital dollars and euros, international receivables, smart corporate cards, and bulk global payouts
Publishes market-by-market regulatory and operational guidance that clarifies the product is not a bank and that local entities and partners handle fiat, card, and virtual-asset functions
Key claims:
The main site says ARQ is “modern finance for the global era” and its business product is designed for companies in Mexico and Brazil that need reliable access to global finance without leaving local markets behind
The homepage legal disclosure says services related to virtual assets in Mexico are provided by DolarApp México S.A. de C.V. and that incoming payments are automatically converted into USDc or EURc
The “Why should I use ARQ?” article says users can protect savings from devaluation, buy digital dollars or euros at the best available exchange rate, and convert balances between several LATAM currencies and digital dollars
The “Borderless account” article says ARQ supports USD, MXN, ARS, COP, and BRL top-ups, with local rails including ACH/Wire, SPEI, PSE, and Pix, and says multiple local-currency deposits are converted into digital dollars automatically
The “Top up my account with dollars (USD)” article says ARQ gives users unique U.S. account and routing details and automatically converts received USD into digital dollars with a fixed US$3 fee per transfer
The “Auto-exchange your top-ups to USDc” article says ARS, EUR, and BRL deposits can be auto-converted into USDc and that MXN and COP already convert to USDc automatically
The Mexico and Brazil regulation articles say ARQ is not a bank, does not accept deposits like a bank, and operates through local regulatory structures while emphasizing SOC 2 certification and security audits
The ARQ Business page says companies can hedge treasury in digital dollars and euros, get paid internationally, issue smart corporate cards, and make bulk payments to vendors and contractors worldwide
Whitepaper: No canonical standalone ARQ or DolarApp whitepaper/litepaper surfaced in this pass. The clearest current sources of truth were the official site, business page, help-center articles on digital dollars and funding flows, and country-specific regulatory guidance; see ../whitepapers/arq-primary-sources-2026-05-06.md.
