Yes within the US. Almost no across the border.
The United States has one of the most active domestic peer-to-peer payment ecosystems in the world. Venmo (acquired by PayPal, with over 90 million users in the US), Cash App (over 50 million monthly active users), Zelle (operated by major US banks, processing more transaction volume than Venmo by some measures), Apple Cash (integrated into iMessage and Apple Wallet), Google Pay, and as of 2023 the Federal Reserve's FedNow real-time settlement network — collectively, Americans have at least four major ways to send money to other Americans instantly, free, and from a phone.
This is the part of the question that gets answered "yes." Within the US, peer-to-peer payments work brilliantly. The user experience that domestic P2P apps provide type a username or email, send any amount, settle in seconds — has reshaped how Americans split bills, settle small debts, pay babysitters, and tip friends.
The part that gets answered "no" is cross-border. None of these systems handle international transfers natively in the way they handle domestic ones. The American user who can split a $30 dinner bill with three friends in two seconds via Venmo is back in the world of bank wires, SWIFT codes, and "1-3 business days" the moment the recipient is in another country.
What works for US-to-US payments
Venmo. The dominant social-flavoured P2P app among Americans aged 18-44. Send to a username, an email, or a phone number; transactions are typically instant, free between users, and visible to friends in a social feed (privacy settings allow opt-out). Limited to US-issued bank accounts and US users.
Cash App. Block's competitor to Venmo, with strong adoption among younger users and a Bitcoin/investing layer that Venmo does not have. Same domestic P2P mechanic — username ($cashtag), instant transfer, free for personal transactions. US-only for sending; Cash App has UK-only operations through a separate product.
Zelle. Owned by a consortium of major US banks. Built directly into bank apps. Send to phone numbers or emails; recipients receive into their bank account directly. Settles in minutes for participating banks. Zelle is US-only and works exclusively between US bank accounts.
Apple Cash. Integrated into iMessage and Apple Pay. Send within iMessage by tapping the dollar sign; settles into the recipient's Apple Cash balance instantly. Limited to US users with US-issued payment cards.
FedNow. The Federal Reserve's real-time payment system, launched in July 2023. Provides 24/7 instant settlement between participating financial institutions. As of 2025, adoption is growing but uneven — many smaller banks and credit unions are not yet connected. FedNow is bank-to-bank infrastructure rather than a consumer-facing app.
Together, these systems provide multiple instant payment paths between any two US users. The fragmentation (which app does which person use?) is a coordination problem, not a capability gap. The capability is there.
Where US peer-to-peer payments stop working
The cross-border failure mode is consistent across the US P2P stack:
Venmo: US-only sending. Cannot send to recipients outside the US. Cannot receive from outside the US. Travelers attempting to use Venmo abroad find the app does not function as a payment surface internationally.
Cash App: US-only for sending. Cash App UK exists as a separate product but does not interconnect with Cash App US for payments — they are operationally separate systems sharing branding.
Zelle: US-only. Tied to the US banking system; cannot send or receive across borders.
Apple Cash: US-only. Requires US-issued payment cards; recipients must be US Apple Cash users.
FedNow: domestic. Federal Reserve infrastructure for US institutions only. Does not handle cross-border settlement.
For an American user wanting to send money to a friend, family member, or business contact outside the US, the options collapse to: an international wire transfer through their bank ($25-$50 fee plus FX margin, 1-3 days), a money transfer service (Wise, Remitly, Western Union — better economics than wires but still requires setup work), PayPal (cross-border-capable but with 4-5% fees and FX margins), or cryptocurrency (technical setup required, recipient needs compatible wallet).
None of these match the in-app simplicity of sending Venmo to a friend in the next neighbourhood.
Within the US, the major peer-to-peer apps — Venmo, Cash App, Zelle, Apple Cash — collectively process trillions of dollars in instant personal transfers annually. None of them handle cross-border payments natively in a way that approaches the same simplicity. The domestic P2P experience is one of the best in the world; the cross-border experience for the same users is one of the worst.

The scenarios where US users hit the cross-border wall
Sending to family abroad. An American with relatives in Mexico, the Philippines, India, Nigeria, or anywhere outside the US who wants to send a birthday gift, monthly support, or emergency money. Venmo does not work. The fallback is Wise, Remitly, or a wire — each requiring setup, each carrying fees, each on a different timeline than domestic settlement.
Splitting a bill on a group holiday. Four friends rent a beach house in Mexico — one American, one Canadian, one British, one Mexican. The American can settle with other Americans via Venmo; with the others, they cannot. The group ends up with a partial Venmo settlement and a partial "bank wire later" that often becomes "I forgot."
Paying a remote contractor or freelancer. A small US business hiring an international freelancer cannot pay through Venmo or Zelle. The fallback is Wise, PayPal, or a wire — each with fees that on small contractor payments are disproportionate.
Receiving from international clients or fans. An American creator with international audience or a small business with international customers cannot receive payments through Venmo or Zelle from those audiences. Cross-border receiving is even more constrained than cross-border sending.
How an S-handle fills the cross-border gap for US users
An Shandle is a single payment identifier on the Spondula network — short, shareable, permanent, global. The Spondula network is being built as a globally inclusive infrastructure, not a country-by-country product like Venmo or Cash App. American users with handles can send to and receive from anyone else with a handle, anywhere the network reaches, with the same instant-settlement experience domestic apps provide for within-country use.
The handle does not replace Venmo, Cash App, or Zelle for domestic US-to-US transfers — those continue to work. The handle adds the cross-border layer that none of those apps provide. American users typically run both: domestic apps for US-to-US (familiar, embedded in social patterns) and the handle for everything that crosses a border.
What it costs: nothing on same-currency transfers. A small transparent exchange spread on cross-currency conversions, shown before confirmation. There is no per-transaction fee, no flat-rate floor, no SWIFT charge.
Within the US, peer-to-peer payments are basically a solved problem. The cross-border gap is the part that has not been solved at the same level of simplicity. The S-handle is what closes it.
Spondula is pre-launch. If you are a US user with friends, family, customers, or contractors outside the country and have ever wished Venmo worked internationally — the waitlist is where the cross-border equivalent becomes available.
Frequently asked questions
Does Venmo work for international transfers?
No. Venmo is US-only it cannot send to or receive from accounts outside the US. The app does not function as a cross-border payment surface. Venmo users wanting to send internationally typically use PayPal (the parent company, which does support cross-border but with higher fees), Wise, Remitly, or a bank wire.
Does Cash App work in the UK or other countries?
Cash App UK exists as a separate product and does not interconnect with Cash App US for payments. American Cash App users cannot send to UK Cash App users through the apps directly. The two share branding but are operationally separate.
What about Zelle for international transfers?
No. Zelle is operated by US banks and works exclusively between US bank accounts. There is no Zelle equivalent for cross-border payments built into the same infrastructure.
Will FedNow eventually support cross-border payments?
FedNow is the Federal Reserve's domestic real-time settlement system. The Federal Reserve has indicated interest in international interoperability over time, but FedNow as currently architected is US-domestic. Cross-border real-time settlement requires linkages to other countries' real-time systems which exist for some country pairs (UPI-Singapore, etc.) but not for the US.
Can I use a Spondula S-handle alongside Venmo or Cash App?
Yes. The handle is independent of any domestic P2P app. American users typically run their existing apps for US-to-US transactions and add the Shandle for everything that crosses a border — international friends, family abroad, international clients, cross-border travel.
Spondula is a global payments network. It is not a bank, exchange, investment platform, or broker. Availability, pricing, and Operator coverage vary by country. Bitcoin rewards depend on real network activity and are not guaranteed. See our terms and conditions for full details.
