Cash App to ARQ: USDC Dollars to Latin America

Disclosure: this guide uses our Cash App and ARQ referral/affiliate links. If you open an account through them, we may earn a small referral bonus at no extra cost to you. This is general information, not financial advice.

A traditional bank wire from a US account to a Latin American bank still costs most people $25 to $50 in flat fees plus a 2% to 4% exchange-rate markup baked into the rate you never see. On a $1,000 transfer that is $45 to $90 gone before the money lands. Cash-pickup services are faster but rarely cheaper, and many charge the most on the exact corridors expats use.

There is now a route that strips most of that cost out by moving regulated dollar stablecoins instead of running money through the correspondent-bank system. As of June 2026, Cash App sends USDC with no transfer fee, and ARQ (formerly DolarApp) turns that USDC into local pesos and pushes it straight to a bank account in Mexico, Brazil, Argentina, or Colombia. This guide walks the whole chain, the real costs, and where it can bite you.

Why moving dollars abroad still costs too much

Most cross-border payments still ride the correspondent-banking network, where two or three intermediary banks each take a cut and the sending bank quietly widens the exchange rate. That is why a "free" transfer can still lose you 3%. Cash-pickup chains add a visible fee on top of a wider spread, and they tend to price the busiest expat corridors the highest.

Stablecoins change the math because the dollar leg of the trip stops touching banks at all. USD Coin (USDC) is a fully reserved, dollar-pegged stablecoin issued by Circle, a US-regulated company. One USDC is designed to always be worth one US dollar. Moving it between two apps is a blockchain transaction that settles in minutes, not a multi-bank relay that settles in days.

Two things made this practical for ordinary people in 2026. First, Cash App finished rolling USDC out to its roughly 60 million users, with transfers on four networks and no fee on the transfer itself. Second, ARQ raised $70 million from Sequoia Capital and Founders Fund in March 2026 and now runs a clean USDC-to-local-bank rail across four Latin American markets. Connect the two and you have a low-friction pipe from a US bank to a Latin American one.

The route in plain English

The whole thing is five moves, and only one of them is "crypto" in any way you have to think about:

1. Fund Cash App from your US bank by standard ACH transfer. This is free and is the same deposit you would do for any Cash App balance.
2. Hold your balance as USDC inside Cash App. When you receive or hold USDC, Cash App treats it as dollars; there is no fee on the USDC transfer.
3. Send the USDC on the Polygon network to your ARQ deposit address. Polygon is a fast, low-cost network, and ARQ covers the network fee on Polygon so the top-up costs you $0.
4. Let ARQ convert USDC to local currency — Mexican pesos, Brazilian reais, Argentine pesos, or Colombian pesos — at the in-app rate.
5. Withdraw to a local bank account over the country's domestic rail. Money typically lands the same or next business day.

Which countries ARQ covers

This is the part that makes the route an "abroad" tool rather than a single-country trick. ARQ is live in four Latin American markets, each wired to the local instant-payment system, so the dollars you send land in a normal local bank account.

Country	Local bank rail	Local currency	What lands
Mexico	CLABE / SPEI	Mexican peso (MXN)	Pesos in any Mexican bank account
Brazil	Pix	Brazilian real (BRL)	Reais by instant Pix key
Argentina	CVU / Alias	Argentine peso (ARS)	Pesos to a CVU or bank alias
Colombia	PSE	Colombian peso (COP)	Pesos to a Colombian bank

Spend without converting everything

Inside the app, ARQ also gives you a USDC dollar account and a global Mastercard, so you can spend straight from the dollar balance instead of converting everything to local currency. That flexibility matters if you earn in dollars but pay rent in pesos.

If your destination is Colombia specifically, it is worth pairing the money rail with a place to actually use the pesos. Once your COP lands, Colombia Move is where expats find housing, jobs, a local marketplace, and a community Q&A — the spend side of the same move. We cover the broader corridor in our Colombia expat platform guide.

Step by step: send your first transfer

Do a small test amount first — $20 to $50 — before you move anything that would hurt to lose. Once one transfer arrives cleanly, repeat the exact same steps for the real amount.

1. Open both accounts. Create a US Cash App account if you do not have one, and open ARQ in your destination country. Both are free to open.
2. Move dollars into Cash App from your US bank by ACH, then make sure your balance is held as USDC.
3. Get your ARQ deposit address. In ARQ, choose to add balance with crypto and copy the USDC deposit address — or scan the address QR — for the Polygon network. ARQ shows the exact network to use.
4. Send from Cash App to that address, selecting the Polygon network to match. Paste the address carefully, or scan the QR.
5. Confirm and convert. The USDC usually arrives in minutes. In ARQ, convert it to local currency at the shown rate, then withdraw to your local bank account.

What it really costs

The crypto legs of this route are free or near-free. The one real cost is the exchange-rate spread ARQ applies when it converts your dollars to local currency, which is small and shown in the app before you confirm. Compare the full stack against the usual options:

Route	Typical flat fee	FX markup	Speed	Best for
Bank wire	$25–$50	2%–4%	1–3 business days	Large one-off transfers
Cash pickup chains	$5–$20	2%–5%	Minutes to hours	Recipient with no bank app
Card remittance apps	$0–$5	0.5%–2%	Minutes to 1 day	Recurring smaller amounts
Cash App → USDC → ARQ	$0	Small in-app spread	Minutes to next day	Dollar earners moving to LatAm

The one cost that remains

Because the dollars travel as USDC until the very last step, you also dodge the layered intermediary-bank fees that make wires unpredictable. You convert to local currency once, at a rate you can see, at the moment you choose. That conversion spread is the only meaningful cost on the whole route, so the habit that saves you money is simple: glance at the live rate before you tap convert.

Risks, limits, and what can change

This route is genuinely cheaper, but it is not zero-risk. Read these before you move real money.

• Wrong network equals lost funds. The single biggest mistake is sending on a network the receiving address does not support. Use Polygon on both ends and test small.
• Cash App's USDC rollout is phased. Access reached users in waves through 2026; if you do not see USDC features yet, your account may not be enabled.
• You need the right accounts. Cash App is a US product tied to US identity, and ARQ requires residency and KYC in Mexico, Brazil, Argentina, or Colombia. The route assumes you control both ends.
• "No fee" is a current policy, not a law. Cash App's free USDC transfers and ARQ's covered Polygon fees are accurate as of June 2026 but can change. Check both apps before a large send.
• Limits and KYC tiers apply. Both apps cap how much you can move until you verify identity, and larger transfers may need extra verification.
• Taxes still exist. Converting US dollars to a 1:1 stablecoin and back usually produces little or no taxable gain, but US persons have reporting obligations on foreign accounts and crypto activity. Talk to a qualified tax professional about your situation.

Data note: figures, networks, and fee policies were checked in June 2026 from Cash App's stablecoin rollout coverage and ARQ/DolarApp's official help documentation. Stablecoin and remittance terms change quickly — verify current rates and limits in each app before sending.

Get started

If you regularly move dollars into Latin America, set this up once and reuse it. Open Cash App for the US-dollar and USDC side, open ARQ for the local-currency side, run one small test transfer, and you have a low-fee corridor you control.

Referral and risk disclosure: the Cash App and ARQ links above are personal referral links — if you sign up through them, both of us may receive a small bonus under each app's current referral terms. ARQ's current referral perk is structured as a small amount placed into a stock position rather than guaranteed cash, which means its value can rise or fall and is not a fixed reward. None of this is financial, tax, or investment advice.
