Is a stablecoin transfer slower than SWIFT?

No. Stablecoin settlement typically happens in seconds or minutes, while SWIFT transfers often take one to five business days.

Under current Brazilian rules, buying and selling cryptoassets, including stablecoins, is not treated as a foreign-exchange (câmbio) transaction subject to the IOF rates that apply to many international remittances. So when funds move on stablecoin rails instead of a traditional wire, the 3.5% IOF on outbound remittances does not apply. You still pay any platform or conversion fee, but there is no IOF on the stablecoin transfer itself. These rules are still evolving, so it is worth confirming the current treatment for your case.

When would I still use SWIFT?

When the recipient only accepts bank wires, when you are dealing with certain currencies, or when institutional requirements mandate traditional banking rails.

Can I use both stablecoins and bank transfers with Ruvo?

Yes. Ruvo connects ACH, RTP, wires, Pix, stablecoin networks and crypto transfers, so funds move across whichever rails are most efficient for a given transaction. SWIFT support will be added as well.

Are stablecoin transfers reversible if I send to the wrong address?

No. Blockchain transfers are irreversible once confirmed. If you send USDT or USDC to a wrong address, the funds cannot be recovered by Ruvo or by the network. Always double-check the address and network before confirming a send. Ruvo shows a confirmation screen with the full address — use it to verify the first and last six characters at minimum against the intended destination.

Do I need to declare stablecoin transfers to Banco Central?

Stablecoin transfers are subject to Brazilian reporting rules for virtual assets. For international transfers above R$1,000 equivalent, the sending institution is required to report under Instrução Normativa RFB 1888/2019. Ruvo handles this reporting for transfers made through the platform. If you transfer to a self-custody wallet and then send abroad independently, the reporting obligation may fall on you — consult a contador familiar with crypto compliance.

Comparison

Stablecoin vs SWIFT

StablecoinSWIFT0% IOFSpeed

Both move dollars across borders, but one was designed in the 1970s for banks and the other settles in seconds on a blockchain. Here is the honest comparison.

Two ways to move dollars internationally

Both SWIFT and stablecoins move value across borders, but they do it very differently. A SWIFT transfer sends messages between banks, which then move money through a chain of correspondent institutions (see how SWIFT works). Every bank in that chain can introduce fees, delays, compliance reviews and operating-hour limits. A stablecoin transfer moves a dollar-pegged digital asset such as USDC or USDT directly on a blockchain network, settles 24/7 and needs no intermediary banks. The difference is like taking a flight with multiple layovers versus flying direct.

Why SWIFT transfers are slow and expensive

SWIFT is still the backbone of international banking, but it inherits the limits of the banking system itself:

Correspondent banks each add cost.
Banks operate in different time zones.
Compliance reviews can create delays.
Transfers pause on weekends and holidays.
The recipient may receive less than was sent, after intermediary fees.

That is why international wires often take one to five business days and cost more than expected.

Why stablecoin rails are growing

Stablecoins have become one of the fastest-growing ways to move dollars because they offer:

Settlement in seconds or minutes.
Availability around the clock, 24/7.
Transparent, on-chain tracking.
Lower operating costs.
Global accessibility.

Instead of coordinating several financial institutions, value moves directly across a blockchain network.

The IOF difference

For Brazilians, the difference that matters most is often tax. A traditional SWIFT transfer sent abroad can carry up to 3.5% IOF under current rules (Decreto 12.499/2025), before FX spreads and wire fees. A stablecoin transfer does not use traditional correspondent-bank foreign-exchange rails, so under current regulation it is not a câmbio operation and that IOF does not apply. The result is often a dramatically lower total cost. You can check the real numbers in how much IOF you pay.

When SWIFT still makes sense

To be fair, SWIFT is not disappearing. It is still the right rail for:

Large institutional settlements.
Counterparties that only accept bank wires.
Certain currencies and jurisdictions.
Traditional banking workflows.

Many major financial institutions are actively exploring how banking systems and digital-asset networks can work together.

How Ruvo moves money

Ruvo does not force every transfer onto a single rail. It combines multiple payment networks and uses the most efficient route available. In the US, Ruvo supports ACH, RTP (Real-Time Payments) and domestic wires; in Brazil, it supports Pix; for digital-dollar settlement it uses stablecoin rails; and you can send and receive crypto directly. SWIFT support will be added for customers who need traditional international wires. The key point: a full end-to-end SWIFT transfer, from a US bank account to a Brazilian one or back, is usually slower and more expensive than routing through local rails and stablecoin settlement. Receiving dollars is free, converting to reais is 0.3% for businesses (0.5% for individuals), and there is 0% IOF throughout. The same rail powers cross-border stablecoin remittances.

The future is hybrid

Cross-border payments are unlikely to be purely SWIFT or purely crypto. The winning approach combines local payment rails such as ACH and RTP, stablecoin settlement for global movement (see ACH vs SWIFT for a full comparison), and traditional banking rails where they are still needed. That mix minimizes fees, shortens settlement times and gives you more flexibility than relying on any single network.
