What just happened with Tether and EFY Finance?

The announcement: Tether + EFY Finance on Oct 13, 2026

On October 13, 2026, Cointelegraph reported that Tether—the issuer of USDT, the world’s largest stablecoin by market cap—is backing EFY Finance to expand stablecoin-based financial infrastructure across Latin America (bloomingbit, Oct 13, 2026). The partnership is not a simple integration; it’s a long-term building project. Tether plans to bring stablecoin payments, custody, and fiat on/off-ramp services to 17 markets across the region through EFY Finance.

Scope: 17 Latin American markets, custody, on/off-ramps

The two companies aim to lay a foundation for stablecoin adoption by providing the core plumbing: safekeeping of digital assets, local currency conversion, and the ability to move in and out of fiat seamlessly. This mirrors the kind of infrastructure that earlier digital payment networks needed to build before merchants and consumers could transact at scale. The scope is ambitious—covering countries from Mexico to Argentina—but the bet is that once the rails exist, demand from businesses and individuals will follow.

Why this is more than just another partnership

Stablecoin issuers have partnered with local wallets and exchanges before. What makes this different is the explicit focus on custody and on/off-ramps at a regional scale. It’s a recognition that stablecoin infrastructure cannot succeed unless businesses can easily convert local currencies to digital dollars and back, and do so with the legal and operational safety they expect from traditional banking. The move also intensifies the stablecoin payments distribution battle we’ve been tracking, where infrastructure providers are racing to own the last mile.

Why does this matter for business stablecoin payments?

The perfect storm: regulatory clarity, infrastructure maturity, demand

PaymentsDive reported in October 2026 that regulatory frameworks like the EU’s MiCA and the GENIUS Act in the U.S. have given companies a clearer compliance map (see PaymentsDive, 2026). Meanwhile, the underlying technology has matured: layer‑2 networks have slashed transaction costs, and major institutions—from Wells Fargo’s stablecoin experiment (OneSafe analysis) to Stripe’s stablecoin adoption push (Stripe)—have validated the model.

LATAM as a live laboratory for real-world stablecoin utility

Latin America has long been a proving ground for financial innovation out of necessity: high inflation, currency controls, and costly remittance corridors make stablecoins an instantly attractive alternative to traditional rails. According to a16z, stablecoin volumes are already eating into payment flows where legacy systems fail (a16zcrypto). Tether’s move essentially builds the backend for that organic demand to go mainstream.

How cross-border businesses are already using stablecoins today

Companies that trade with LATAM are using USDT and USDC to settle invoices in hours instead of days, avoid intermediary bank fees, and bypass currency volatility. However, most of these flows still rely on a patchwork of exchanges, OTC desks, and manual processes. The EFY rollout promises to standardize that experience, but the infrastructure gap for global businesses—not just local wallets—remains a critical bottleneck.

Which stablecoins and blockchains are supported for payments today?

For B2B payments, the market has coalesced around a handful of options. USDT (Tether) and USDC (Circle) dominate, with DAI seeing niche use. Supported blockchains vary by provider: Ethereum remains a base layer for large-value settlements, while TRON and Solana handle a growing share of low-cost, high-speed transactions (see our analysis on TRON vs. XRP in web3 payments). Layer‑2 networks like Polygon and Arbitrum are also gaining traction for B2B flows because they combine security with sub‑cent fees. The EFY partnership will likely leverage multiple chains to optimize cost and speed across 17 markets, though exact network choices remain undisclosed.

How do business on/off-ramps work in practice?

The real chokepoint for stablecoin payments isn’t the transfer itself—it’s the edges. A business must be able to receive fiat (say, a wire in Brazilian real), convert it to USDT, hold that USDT safely, and then later convert back to fiat (e.g., USD) for payroll or vendor payments. A practical crypto on-ramp for businesses needs to make that edge flow as simple as a local bank transfer. This requires:

• A custody solution that keeps assets secure without requiring private-key management expertise.
• A banking partnership that can settle fiat legs reliably, often across multiple jurisdictions.
• An exchange or conversion mechanism with deep liquidity and transparent pricing.

EFY Finance’s mandate is to provide all three at a regional level. However, for a global startup or DAO that already banks in the U.S. or Europe, plugging into a LATAM‑specific on‑ramp can create fragmentation. This is where platforms that combine traditional banking and crypto rails under one roof solve a real problem—as we’ve explored, crypto banking now demands that digital assets connect to real bank accounts. Without that bridge, companies are forced to juggle multiple providers, increasing cost and counterparty risk.

What are the real costs and hidden fees of stablecoin payments?

The headline narrative is that stablecoin payments are “near‑free,” but the full picture includes several cost layers. Below is a transparent fee schedule using OneSafe’s published pricing as a concrete example—it’s a neobank platform that combines fiat and crypto accounts, so it illustrates what a business actually pays end‑to‑end.

The takeaway: while on‑chain transfers can cost pennies, the stablecoin payment fees that matter most to businesses are the fiat on/off‑ramp costs. A wire deposit of $10 or a 0.15% ACH fee is often lower than traditional correspondent banking, but the hidden danger is uncompetitive FX conversion—some platforms embed a 1‑2% spread on crypto‑to‑fiat swaps. By contrast, providers that offer USDC deposits free and quote an explicit conversion fee eliminate that opacity.

How can startups and DAOs accept stablecoins without building infrastructure?

For most companies, the idea of building their own stablecoin treasury, integrating with a custody provider, and managing compliance is a non‑starter. The practical path is to partner with a financial platform that speaks crypto natively. This removes the need to:

• Hire a blockchain engineer.
• Negotiate custody agreements with a third‑party custodian.
• Piece together fiat banking and crypto liquidity from separate vendors.

One model—and the one that has gained traction among web3 startups and DAOs—is a neobank stablecoin platform like OneSafe, where a single interface provides global accounts, corporate cards, instant crypto‑to‑fiat conversion, and on‑chain custody secured by Fireblocks. DAO stablecoin payments particularly benefit from customizable roles and permissions, which allow them to separate treasury management from day‑to‑day spending without sacrificing speed.

Step 1: Choose a banking partner that speaks crypto (and why it matters)

A banking partner that understands crypto will already have compliance protocols in place for on/off‑ramps. Without this, each fiat‑to‑crypto movement can trigger reviews or account freezes. OneSafe’s fully digital onboarding—typically completed within a week—illustrates how modern platforms can meet KYB standards without physical paperwork.

Step 2: Set up segregated accounts and automate on/off-ramps

Receive fiat in a dedicated global account, convert to USDT or USDC automatically via an API or dashboard, and hold the proceeds in a segregated custody wallet. This maintains a clear audit trail and eliminates manual conversion delays.

Step 3: Navigate compliance without losing speed

The latest stablecoin regulation updates show that regulators are watching. Businesses should ensure their platform restricts transactions from OFAC‑sanctioned jurisdictions and enforces Multi‑Factor Authentication (MFA) by default. OneSafe’s MFA requirement and its explicit policy of not serving sanctioned countries or certain U.S. states demonstrate what to look for.

What compliance risks should businesses consider?

Stablecoin payments introduce compliance risks that don’t exist with pure fiat rails. The key ones:

• Sanctions and AML: Even a peer‑to‑peer stablecoin transfer can inadvertently violate sanctions if the recipient address is on an OFAC list. Reputable platforms screen transactions and restrict high‑risk jurisdictions, but DIY setups shift that burden to the user.
• Lack of chargeback mechanisms: On‑chain payments are final. For B2B payments, this means a mis‑sent transfer can be impossible to reverse. A business must have robust internal controls and a partner that can, at minimum, flag anomalous transactions.
• Evolving licensing requirements: As the Stablecoin Standard notes, regulators in different countries are moving at different speeds. Operating in 17 LATAM markets will require navigating a patchwork of rules; businesses that piggyback on a platform that aggregates that compliance effort avoid a legal minefield.

Open Questions and What to Watch Next

Will other stablecoin issuers follow Tether into LATAM?

Circle (USDC) has been active in the region through partnerships, but no issuer has matched Tether’s commitment to building multi‑market, full‑stack infrastructure via a single vehicle like EFY. The competitive response will indicate how strongly the industry believes that owning the last mile is worth the investment.

How will local regulators in each of the 17 markets respond?

Latin American regulators have shown a spectrum of attitudes—from Brazil’s relatively progressive framework to more cautious stances elsewhere. A coordinated push that treats regulation as a pre‑competitive enabler, rather than an afterthought, will determine the speed of adoption.

The missing pieces: refunds, chargeback mechanisms, and consumer protection

Stablecoin payments excel at fast, low‑cost settlement, but they lack the dispute resolution mechanisms that businesses rely on in traditional card networks. For B2B payments with established relationships, this is manageable; for broader merchant adoption, it remains an unsolved problem that will likely require on‑chain escrow protocols or insurance‑backed guarantees.

Key Takeaways

• Tether’s EFY Finance partnership is the largest infrastructure play to bring custody and on/off‑ramps for stablecoin payments to 17 Latin American markets, signaling that the race for last‑mile infrastructure is heating up.
• For businesses, the real cost of stablecoin payments is not on‑chain gas but the hidden fees in fiat conversion and wire transfers; transparent pricing models (like free USDC deposits and 0.25% FX) are what to look for.
• Startups and DAOs can skip building their own custody and banking stack by using a neo‑banking platform that handles both fiat and crypto rails natively, saving weeks of integration and reducing compliance risk.
• The missing piece for mainstream B2B stablecoin adoption is not technology but operational safety—specifically, chargeback equivalents and regulatory harmonization across jurisdictions.
