PayFi is a broad industry term for payment-related financial services that combine digital-asset or blockchain payment rails with financial functions such as credit. In a typical stablecoin cross-border payment, local currency is converted to a stablecoin, the token moves over a blockchain, and the recipient or a payment provider converts it to local currency or pays it out from a wallet. The blockchain transfer can be fast, but it does not by itself guarantee that the recipient has spendable funds quickly or at a lower total cost.
What PayFi means
PayFi does not have one universally accepted formal definition in the sources cited here. The term is used for services that connect payments with financial products, including credit, through digital-asset infrastructure. One example is Huma Finance: Visa’s 2025 report describes it as a payment-financing platform using blockchain and stablecoins for cross-border payment financing, card financing, trade finance, and related services. Visa’s report is an example of how the label is being used, not a definitive industry standard.
For someone sending money internationally, the relevant distinction is usually not the label but the route the payment takes, where conversion happens, and when the recipient can actually use the funds.
How a stablecoin cross-border payment works
- Fund and convert: The sender or sending institution provides local fiat currency and obtains a stablecoin through an on-ramp, banking partner, or custodian. The exchange rate, fees, and any foreign-exchange spread affect the amount available to send. Visa’s stablecoin payments explainer describes this conversion stage.
- Transfer on-chain: The stablecoin is sent to a recipient wallet or payment institution using a blockchain. Visa identifies Stellar, Ethereum, and Solana as examples; the transfer is recorded and verified on-chain, and timing depends on the network and implementation.
- Receive and pay out: The receiving wallet or institution accepts the token. It may deliver the token to the recipient or convert it into local fiat and pay it out through a local channel. That final step depends on available liquidity, provider processes, and the receiving side’s authorization and infrastructure.
- Add financing, where offered: Some PayFi arrangements place credit around payment flows. Visa describes Huma as offering revolving credit lines, receivable-backed credit, and receivables factoring in stablecoins. Businesses can use these services to accelerate cross-border payments or supplier payouts; this is a financing feature, not a necessary part of every stablecoin transfer. Visa’s Huma case study describes the example.
What stablecoin rails may change—and what they do not promise
Visa identifies possible advantages over conventional correspondent-bank routes, including fewer intermediaries, operation outside standard banking hours, on-chain visibility, and faster settlement. In business payments, stablecoin settlement may complement card acceptance and shorten settlement or FX windows, potentially giving suppliers earlier access to funds. These are potential benefits, not guarantees of lower total cost, better exchange rates, or quicker final payout in every corridor. Visa’s cross-border explainer and its B2B stablecoin payments page describe these use cases.

Compare the complete payment journey, rather than just the blockchain leg:
- Time to usable funds: Measure from funding on the sending side to the moment the recipient can use the money—not merely the time it takes the token to move on-chain.
- All-in cost: Include sender and recipient fees, conversion charges, and the exchange rate or FX spread on both sides.
- Intermediaries and availability: Check how many providers handle the transfer and whether funding, conversion, and payout are available outside banking hours.
- Visibility and reconciliation: Establish what the sender and recipient can track, and whether transaction records fit their accounting and payment processes.
- Reach and liquidity: Confirm that the recipient can access the required token and that it can be converted or spent locally in the needed amount.
- Legal and counterparty exposure: Assess the rules, stablecoin arrangement, issuer, custody, redemption process, and providers involved in the specific route. The BIS Committee on Payments and Market Infrastructures report stresses that suitability and risks depend on design and jurisdiction.
Visa’s B2B page puts the broader point this way: “The future of payments won’t be defined by a single rail; It will be defined by choice, where consumers and businesses can seamlessly use fiat, stablecoins or both within a trusted network.” That is Visa’s corporate statement, not a quote attributed there to a named individual.

Risks and limitations to check
Local rules differ
Regulatory frameworks and supervisory approaches vary by jurisdiction and continue to develop. Visa references the EU’s Markets in Crypto-Assets framework (MiCA) and U.S. legislation while emphasizing compliance in each jurisdiction. A route that works in one country may not be available or authorized in another. Visa’s explainer discusses the regulatory landscape; the BIS CPMI report examines jurisdiction- and arrangement-specific considerations.
The token transfer is only one leg
On-chain movement can complete before onboarding checks, compliance review, conversion, liquidity sourcing, or local payout. Ask the provider what its quoted “settlement” time measures and when the recipient will have access to funds.

A payment can depend on the token’s design and issuer, custody arrangements, service providers, redemption processes, and access to liquidity. The BIS CPMI report treats stablecoin arrangements as one possible approach to cross-border payment frictions, not a universal solution; it cautions that drawbacks may outweigh benefits even when a particular friction is reduced. See the BIS report.

Visa and Solana: a scoped live pilot
Solana’s institutional payments page says Visa has moved millions of USDC between issuer and acquirer partners in live pilots on Solana to settle fiat-denominated payments authorized over VisaNet. The page does not provide an exact count or publication date for that claim. It supports a statement about those pilots—not a claim that Visa has moved its entire cross-border network to blockchain settlement. Solana’s institutional payments page provides the description.

Other uses and plans listed by Solana
Solana lists cross-border payments, card settlement, treasury, and global payouts among its payment use cases. Its page describes Worldpay merchant settlement in USDG and Fiserv’s FIUSD, and describes Western Union’s USDPT as planned for launch in 2026. A planned launch is not proof that a service has launched or is available to a particular customer or corridor; confirm its current status and terms with the provider. Solana’s page contains these descriptions.
Huma figures are a case study, not a market total
