Arc payment corridors in Latin America — what's actually confirmed

Four names come up constantly in industry lists of Latin American payments infrastructure relevant to stablecoins — dLocal, EBANX, BTG Pactual, and Bitso — and none had a confirmed, sourced connection to Arc specifically as of 2 Sep 2026. This guide names each honestly, describes the real local rails a corridor connects to (Brazil's Pix, Mexico's SPEI, Argentina's Transferencias 3.0), and covers corridor mechanics that apply regardless of any specific company's Arc relationship being confirmed. Arc mainnet launches 16 September 2026; nothing here is live as of 2 Sep 2026.

The names in industry lists, checked against what's sourced

dLocal, a major LatAm cross-border payments processor connecting global merchants to local payment methods, appears in general Arc-adjacent commentary but not in Circle's own named integration lists. No dated, sourced Arc relationship was found. Not yet confirmed as of 2 Sep 2026.

EBANX, a Brazil-headquartered payments company deeply integrated into local rails including Pix, has no dated, sourced Arc-specific relationship found. Not yet confirmed as of 2 Sep 2026.

BTG Pactual, one of Latin America's largest investment banks with a growing digital-assets business generally, has no dated, sourced Arc-specific relationship found. Not yet confirmed as of 2 Sep 2026.

Bitso, a major LatAm crypto exchange with substantial USDC and cross-border stablecoin payment volume already, has no dated, sourced Arc-specific relationship found. Not yet confirmed as of 2 Sep 2026.

All four are credible, established players in LatAm payments or crypto infrastructure broadly — that credibility doesn't, on its own, establish an Arc-specific claim, and this guide won't infer one without a source. If any confirms an Arc relationship after 2 Sep 2026, that's new information this guide doesn't yet have.

Brazil: Pix

Pix is Brazil's instant payment system, operated by the Banco Central do Brasil, launched November 2020. It enables real-time transfers between bank accounts and digital wallets continuously, and has become the dominant payment method for a large share of everyday transactions, per the BCB's own materials. Pix is a domestic, fiat rail — it moves Brazilian reais between Brazilian institutions, not stablecoins, and isn't itself a blockchain system. For a stablecoin corridor, Pix is relevant as the last-mile rail a licensed local partner uses to deposit reais after a USDC-to-real conversion — not a rail moving USDC directly. Any claim that stablecoins "settle via Pix" should be read carefully: what's actually happening is a conversion step followed by an ordinary Pix transfer of the resulting reais.

Mexico: SPEI

SPEI (Sistema de Pagos Electrónicos Interbancarios) is Mexico's interbank system, operated by Banco de México, supporting near-real-time transfers between participating institutions. Like Pix, it's a domestic fiat rail, not a stablecoin system — its relevance is the same: the local last-mile rail after conversion, not a channel moving USDC itself. Worth noting: SPEI transfers, while typically near-instant, can be affected by bank-specific processing windows and verification holds a corridor operator should account for in payout timing.

Argentina: Transferencias 3.0 and CBU/CVU

Argentina's real-time payment infrastructure centers on Transferencias 3.0, a scheme developed under the Banco Central de la República Argentina to enable interoperable instant transfers across CBU (traditional bank accounts) and CVU (virtual wallet accounts) identifiers — connecting traditional banks and the fintech-wallet sector that dominates Argentina's payments landscape. As with Pix and SPEI, this is a domestic peso rail, not a stablecoin system; its relevance to any Arc-based corridor is again as the last-mile disbursement rail after conversion. Argentina is also a market with unusually high stablecoin adoption for informal dollar-savings, given the country's currency-volatility history — a demand driver distinct from the merchant- and corridor-payment use case this guide otherwise focuses on.

What a LatAm corridor needs, same four pieces as anywhere else

Local liquidity in reais, pesos, or the relevant currency. A licensed payout partner authorized to disburse domestically — a genuinely significant regulatory lift in Brazil and Mexico specifically, both with well-developed, actively enforced licensing regimes. FX, converting USDC into local currency at a real, priced spread with real counterparty risk. A cash-out network, mattering somewhat less in Brazil and increasingly urban Mexico given how dominant digital-wallet payment has become, and more in Argentina's informal-dollar context.

The honest framing

LatAm's stablecoin activity today skews toward informal dollar-savings demand (concentrated in Argentina) and toward crypto-exchange and remittance flows already running through players like Bitso, rather than a confirmed Arc-specific corridor. None of the major LatAm payments names carry a sourced Arc relationship as of 2 Sep 2026 — a materially different starting point than Africa's picture, where Thunes carries a direct, named Arc integration from Circle's own press release. Compare Built on Arc's Africa corridor guide against this one: the asymmetry reflects what's actually sourced, not an editorial judgment about which region matters more.
