Stablecoin rails and cross-border payouts for remittances

Typically, remittance companies move money between different countries using local payout partners. The sender uses an app or visits an agent or bank to make a transaction, fills out some paperwork, and pays the covering fees and foreign exchange (FX) spreads. Then, the sender's institution passes instructions to a partner in another country to pay the recipient the appropriate amount. Settlement happens later via correspondent and intermediary banks.

This process is time-tested and reliable, but it isn't right for every type of payment. Fees for lower-value remittances can add up quickly, with the World Bank putting the global average cost of sending $200 across borders at 6.36% in Q3 2025. Plus, in order to ensure timely payouts, correspondent banks typically require senders to prefund partner accounts. This ties up capital and increases inefficiency.

Stablecoin rails address these issues by adding a complementary settlement layer alongside existing partnerships. This guide explores how remittance companies use this infrastructure to enable faster cross-border payouts with always-on settlement. It also looks at why local payout partners are still essential and whether it makes more sense to buy stablecoin infrastructure or build it in-house.

What stablecoin infrastructures do remittance companies use?

Remittance and international payment companies often use the "stablecoin sandwich" model for cross-border remittances. This means that rather than requiring senders and recipients to deal in stablecoins directly, each party sends or receives their local currency through local on- and off-ramp partners. There's no need for customers to worry about wallets or custody, and they get the user experience they're accustomed to.

Also, onchain settlement isn't subject to banking business hours, so the settlement leg can move faster and costs less than correspondent banking. The full cost of a payout still depends on the ramp providers, FX conversion and local payout partners in each corridor. Remittance companies can hold more of their float in a dollar-denominated stablecoin balance, although local payout providers still need liquidity in each currency they pay out.

Application programming interfaces (APIs) tie these layers together, connecting stablecoin settlement to existing payment systems and making execution programmable. Teams can trigger and track payments automatically and more easily reconcile them with internal records.

Why stablecoin settlement still needs local payout partners

Stablecoin infrastructure doesn't replace local delivery. Instead, it sits alongside existing rails to provide a new settlement layer. Here's how it works.

Stablecoins handle settlement, not delivery

Stablecoins carry value from one end of a cross-border transfer to the other. On-ramp partners convert the sender's local currency into stablecoins, and off-ramp partners convert them back into fiat. Then, the off-ramp partner delivers the funds to the recipient's bank account in their own local currency. Customers typically never even see stablecoins, and from their perspective, nothing about the payment flow changes.

Consider Felix, a fintech that uses WhatsApp and stablecoin rails to simplify cross-border remittance. Felix is scaling and wants to build redundancy to stay reliable as volume grows. That's why the business is partnering with Tempo: to take advantage of cost predictability, onchain settlement in under a second, and dedicated payment lanes.

Local partners deliver the final payout

A stablecoin settlement layer doesn't change the fact that the last mile of any remittance is still local rails. Remittance companies still need local partners to complete bank transfers or reserve cash for pickup so recipients can withdraw or spend the money as they normally would.

This reliance on local infrastructure means partner coverage is the primary constraint on reach and business expansion. While stablecoins can travel anywhere, the payouts themselves depend on local off-ramp partners and their unique operating hours and payment methods.

Licensing and compliance stay in-house

Stablecoin settlement has its benefits, but it doesn't eliminate regulatory responsibility. Remittance companies still need to satisfy core obligations to stay compliant, such as licensing, know your customer (KYC)/anti-money laundering (AML), and sanctions screening.

Coastal shows what this looks like on the ground. The bank is building a cross-border payment corridor that adds stablecoins at the settlement level while preserving existing compliance infrastructure. Messaging, KYC/AML screening, and bank-to-bank confirmations don't change, so Coastal can use stablecoin settlement without having to overhaul its compliance stack.

Buying vs. building stablecoin infrastructure

Whether to build or buy a cross-border payment solution depends on a company's resources and timeline. Here's what you need to know.

The hidden workload behind a complete in-house stack

Building stablecoin infrastructure can be time-consuming, and the overhead and operational costs can be significant. Integrating a blockchain is just the start. A full build includes:

• Custody and key management. The private keys that control a remittance company's stablecoins need strong protection. Losing access to signing keys can make funds inaccessible if there is no recovery mechanism. The operational overhead of managing keys can also be substantial, requiring companies to devise access policies and approval workflows.
• On- and off-ramp partners. For each country a business serves, it needs on- and off-ramp partners to convert funds at each end. Developing and maintaining these relationships means vetting partners, negotiating terms, and integrating each new partner's systems.
• Liquidity management. To cover payouts in a timely manner, remittance companies need to ensure that they maintain enough liquidity. They also want to avoid tying up too much capital that they might better use elsewhere.
• Compliance. KYC/AML, sanctions screening, and reporting may require companies to juggle obligations across jurisdictions.
• Ongoing maintenance and monitoring. Stablecoin infrastructure requires constant upkeep to stay on top of changes in networks and regulatory requirements.

Why companies use APIs instead of building stablecoin rails

Payment APIs allow remittance companies to add stablecoin settlement to their existing payout flows. The provider handles the onchain infrastructure, while licensing, compliance, and local partnerships stay with the remittance company.

Deel's work with Tempo is an example of a company relying on outside infrastructure rather than building complex rails in-house. Deel wanted to give freelancers and contractors based in countries with volatile local currencies a way to hold dollar-denominated balances. Instead of spending time and money creating its own infrastructure, the company decided to launch a dollar-backed stablecoin wallet on Tempo. Workers get a stable store of value without leaving the platform, while Deel sidesteps unpredictable costs and account rent.

Tempo as the settlement layer for cross-border payouts

Tempo is settlement infrastructure purpose-built for stablecoin payments. Enterprises that need to move money within or across borders benefit from:

• Predictable fees. Businesses can use stablecoins instead of volatile gas tokens to cover network costs, typically for less than a cent.
• Sponsored fees. Network fees can be paid on behalf of users, so they don't come out of the payment amount.
• Dedicated payment lanes. Tempo sets aside blockspace specifically for payments. Spikes in other types of activity won't slow down settlement or make payouts impractically expensive.
• Settlement in under a second. Stablecoin payments on Tempo settle onchain in under a second, with no re-orgs.

Latin American fintech ARQ shows how this works for a large customer base. The company is moving its settlement infrastructure onto Tempo and plans to take advantage of features like dedicated payment lanes, built-in compliance controls, and stablecoin-denominated fees. The user experience stays the same for ARQ's more than two million customers, while cross-border payouts become faster and more affordable.

See how you can get faster settlement without letting go of your existing banking partners with Tempo's cross-border payout infrastructure.

FAQ

Do companies have to hold volatile assets to use stablecoin rails?

No, remittance companies and other finance businesses typically only have to hold dollar-backed stablecoins to use stablecoin rails. Some companies don't even hold stablecoins, instead working with on- and off-ramp partners to convert funds at each end of a transaction.

Do stablecoin payouts comply with remittance regulations?

They can, as long as companies satisfy regulatory requirements in each jurisdiction they operate in. Some stablecoin rails add enforcement at the settlement layer, such as allowlists, blocklists, and the ability to freeze or pause transfers. This can simplify compliance, but it's not a hands-off solution. Businesses may still need to configure and monitor enforcement rules in addition to taking care of licensing, KYC/AML, and sanctions screening.

Can remittance companies pay in local currency, or only stablecoins?

Recipients can still receive local currency because off-ramp partners convert stablecoins at delivery. The stablecoin layer handles settlement. It doesn't change how recipients are paid or replace local payout rails.
