What Is Visa USDC Settlement on Solana?
On September 5, 2023, Visa announced that it had expanded its stablecoin settlement program to the Solana blockchain, using USDC (a dollar-pegged stablecoin issued by Circle Internet Financial) with merchant acquirers Worldpay and Nuvei. The announcement described mainnet activity rather than a testnet demonstration, but it should not be treated as evidence of the program's current scale or counterparties without checking Visa's latest disclosures. "Settlement" here refers to the back-end transfer of funds after card authorization.
Visa is a payment network, not a bank. It operates the rails that connect cardholders, card-issuing banks, and the financial institutions that process payments on behalf of merchants. Cuy Sheffield, Visa's Head of Crypto at the time of the announcement, was a spokesperson for the program. The 2023 disclosure positioned Solana as a second settlement blockchain alongside Ethereum, not a replacement; present activity on either chain should be verified.
The program operates entirely in the infrastructure layer between Visa and its acquirer partners. Visa is not "accepting crypto" in any consumer-facing sense, and cardholders are not interacting with USDC or Solana at checkout. The stablecoin settlement happens in the back-end plumbing of the payment system, invisible to anyone holding a Visa card.
What Is USDC? Understanding the Stablecoin Behind the Settlement
USDC (USD Coin) is a stablecoin, a type of cryptocurrency pegged 1:1 to the US dollar, issued by Circle Internet Financial. Unlike Bitcoin or Ether, whose market prices fluctuate, one USDC always equals one dollar. This price stability is what makes USDC functional for financial settlement: Visa can transfer a precise dollar amount on-chain without exposure to cryptocurrency price volatility. USDC runs natively on multiple blockchains, including Solana and Ethereum. It is not a Central Bank Digital Currency (CBDC) and not a government-issued instrument. It is a privately issued stablecoin, distinct from competing products like USDT (Tether), which has a different issuer and reserve structure.
Circle Internet Financial is the company that issues USDC and manages the dollar reserves backing it. Circle took full stewardship of USDC in 2023, after dissolving the Centre Consortium it had co-founded with Coinbase to govern the stablecoin. Visa does not issue or control USDC. It uses Circle's stablecoin as the settlement currency, which means Visa's blockchain settlement program depends on Circle's operational and regulatory standing. For acquirers participating in the program, this introduces a third-party dependency worth factoring into risk assessments.
A settlement system needs predictable values. If the asset used for settlement swings 10% in value overnight, the settlement process breaks down. Because one USDC always equals one dollar, Visa can use it the same way it would use fiat currency in a wire transfer, routing it through a blockchain instead of a correspondent banking chain. (PayPal also launched its own stablecoin, PYUSD, in August 2023, one month before Visa's Solana announcement, signaling that major payment companies were converging on dollar-denominated digital assets around the same time.)
How Payment Settlement Works: The Traditional Process Explained
A card transaction has two distinct phases that most people conflate. Authorization happens in real time: when you tap your card, Visa's network confirms within seconds that the transaction is approved. Payment settlement is a separate process, the actual transfer of funds from Visa to the merchant's bank that occurs one to two business days after the transaction, which the industry notates as T+1 or T+2. Merchant acquirers are the banks and processors that receive card payment funds on behalf of merchants. Worldpay and Nuvei are both acquirers in this sense.
Traditional settlement carries significant friction, particularly across borders. Funds move through correspondent banking networks, chains of intermediary banks that communicate international payment instructions via SWIFT, a global messaging network. SWIFT itself is not a payment system; it communicates instructions, while the actual funds move through those correspondent bank relationships. Each intermediary adds time and fees. A domestic settlement might clear in T+1; a cross-border settlement routed through multiple correspondent banks can take one to five business days, with layered fees at each step.
Settling a payment on a blockchain changes that model entirely. Instead of routing funds through correspondent banks over one to two days, Visa transfers USDC on the Solana blockchain. The transfer settles on-chain in seconds, with the acquirer receiving USDC directly in a digital wallet, and the transaction is final and publicly verifiable on the Solana ledger.
Traditional Settlement vs. Visa USDC Settlement on Solana
| Dimension | Traditional Settlement (SWIFT / Correspondent Banking) | Visa USDC Settlement on Solana |
|---|---|---|
| Settlement Speed | 1 to 2 business days domestic; 1 to 5 days cross-border | ~2 to 3 seconds (near-real-time) |
| Cost per Transaction | Variable: SWIFT fees + correspondent bank fees + FX spreads | SOL-denominated base and optional priority fees; USD value varies |
| Number of Intermediaries | Multiple: issuing bank, card network, acquirer, correspondent banks | Minimal, direct on-chain transfer |
| Settlement Finality | Batch-processed; reversible until final posting | On-chain finality in seconds; publicly verifiable |
| Cross-border Capability | Slow, expensive, opaque | Near-real-time, minimal cost |
| Auditability / Transparency | Internal bank records; opaque to outside parties | Publicly verifiable on the Solana ledger |

How Visa's USDC Settlement on Solana Works: Step by Step
In the settlement flow Visa described in September 2023, the blockchain replaced the traditional fiat channel for the specific leg where funds moved to an acquirer. Visa transferred USDC on Solana to the acquirer's digital wallet. Confirmation timing depends on network conditions and the commitment level selected by the parties; the announcement does not guarantee a fixed settlement time for every transfer.
Here is the full settlement flow:
- A cardholder makes a purchase with a Visa card at a merchant whose payment processor is Worldpay or Nuvei.
- The transaction is authorized in real time through Visa's existing network. This step is identical to traditional card authorization and is completely unchanged.
- At settlement time, instead of routing fiat currency through correspondent banking channels, Visa initiates a USDC transfer on the Solana blockchain, using smart contracts (self-executing programs on the blockchain) to automate the transfer between settlement accounts.
- USDC is transferred to the acquirer's designated Solana wallet address, the on-chain equivalent of the bank account that receives settlement funds in the traditional model.
- The transfer is confirmed on-chain according to the commitment level and operational policy selected for the workflow, rather than a guaranteed fixed number of seconds.
- The acquirer receives USDC and may hold it or convert it to fiat currency as needed. This conversion decision belongs to the acquirer, not Visa.
Receiving USDC settlement on Solana is not a passive capability. Acquirers need wallet or custody infrastructure, integration processes, liquidity arrangements, and compliance controls for stablecoin receipts. Visa named Worldpay and Nuvei in its September 2023 announcement, but the public disclosure does not by itself establish their current volume, configuration, or program status.
Solana fees are paid in SOL and may include base and priority components. They have often been low in USD terms, but the dollar cost varies with network conditions and SOL's market price and should not be quoted as a fixed amount.
Why Did Visa Choose Solana? Solana vs. Ethereum Explained
Visa's September 2023 announcement cited Solana's throughput and low transaction costs when explaining the expansion. The commonly cited figure of roughly 65,000 transactions per second is a theoretical benchmark, not observed Visa settlement capacity, and fees vary. Visa did not describe Solana as a replacement for Ethereum; it added a second settlement blockchain.
Solana's performance profile comes from its Proof of History consensus mechanism, which sequences transactions using a built-in cryptographic timestamp rather than requiring network-wide agreement before each transaction is recorded. The practical outcome is transaction finality in approximately 2 to 3 seconds without the confirmation latency common to other Layer 1 blockchains. Solana also hosts a broad decentralized finance (DeFi) ecosystem with lending and trading protocols, a signal that the network is a full-featured smart contract platform rather than a single-purpose payment chain.
Solana vs. Ethereum (Mainnet): Settlement Performance Comparison
| Dimension | Solana | Ethereum (Mainnet) |
|---|---|---|
| Transaction Throughput (TPS) | Theoretical benchmark near 65,000; realized throughput depends on workload and methodology | Base-layer throughput varies by workload |
| Average Transaction Fee | SOL-denominated base and optional priority fees; USD value varies | Variable gas fees |
| Confirmation / Finality | Depends on commitment level and network conditions | Block confirmation and finality are separate thresholds |
| Visa Settlement History | Added September 5, 2023 (with Worldpay, Nuvei) | First used March 2021 (with Crypto.com) |
| Institutional Ecosystem Maturity | Growing; significant DeFi and developer activity | More established; larger institutional precedent |
| Consensus Mechanism | Proof of History + Proof of Stake | Proof of Stake (post-Merge, September 2022) |

Sheffield framed the Solana expansion as part of Visa's goal of enabling settlement in any currency, whether fiat or digital, citing Solana's settlement speed and low cost as the fit for high-volume payment operations.
Ethereum carries genuine advantages that the table does not fully capture: a larger institutional ecosystem, a deeper developer base, and a longer track record as the dominant platform for institutional blockchain activity. Ethereum Layer 2 networks such as Arbitrum and Optimism also exist, though they are not part of Visa's current settlement program. Visa's decision to maintain both chains reflects that each serves a different purpose. Solana's throughput and cost suit the settlement use case; Ethereum's depth suits other institutional applications.
Visa's Crypto History: From Ethereum to Solana
Visa's September 2023 Solana expansion is the latest step in a multi-year strategy to position blockchain as a viable settlement rail alongside traditional fiat infrastructure, not a sudden pivot but a measured extension of work that began years earlier.
Visa's blockchain milestones:
- 2020: Visa partners with crypto companies to enable Visa cards linked to crypto wallets, establishing the first programmatic connection between Visa's payment rails and the crypto ecosystem.
- March 2021: Visa launches its first USDC payment settlement pilot on the Ethereum blockchain, with Crypto.com as the acquirer partner. Real USDC transfers occur on Ethereum mainnet, establishing the blockchain settlement model the Solana program would later extend.
- September 5, 2023: Visa announces the expansion of its USDC stablecoin settlement to the Solana blockchain, naming Worldpay and Nuvei as the acquirer partners. Sheffield, who has led Visa's crypto strategy throughout this arc, describes the move as part of Visa's goal to settle in "any currency, fiat or digital."
The Solana expansion is notable because it extends the blockchain settlement model to a second chain with fundamentally different performance characteristics than Ethereum, which is the specific reason Solana was selected for this use case.
What This Means for Payments and Crypto Adoption
Visa's September 2023 disclosure is evidence that a major payment network tested and used public-blockchain settlement for a defined workflow with named acquirers. It does not establish current transaction volume, continuing participation, universal reliability, or suitability for another institution. Organizations evaluating a similar model still need independent technical, legal, custody, liquidity, counterparty, and compliance review.
For investors tracking Solana's institutional adoption trajectory, settlement transactions denominated in USDC still pay minimal fees in SOL, creating incremental demand for the network's native token. Institutional adoption signals like this have historically correlated with increased network credibility, though market price impacts depend on many factors beyond any single program announcement.

Visa is not alone in this direction. Mastercard is pursuing stablecoin and CBDC payment capabilities across multiple blockchain networks, signaling that this is an industry-wide shift rather than a Visa-specific move. PayPal launched PYUSD (its own stablecoin, issued by Paxos Trust Company) in August 2023, one month before Visa's Solana announcement, as further evidence of a fintech-wide inflection toward dollar-denominated digital settlement assets.
For cross-border payments specifically, the implications are concrete. Traditional cross-border settlement through SWIFT correspondent banking carries one to five business days of delay and layered intermediary fees. Blockchain settlement via USDC on Solana positions Visa to offer near-real-time cross-border fund movement at a fraction of the cost, faster and lower-cost for this specific settlement use case, though SWIFT handles a far broader range of financial messages and currencies than Visa's current Solana program covers.
What This Does NOT Change for Visa Cardholders
For everyday Visa cardholders, nothing changes. You continue to tap, swipe, or enter your card details at checkout exactly as you always have. USDC and Solana operate in the settlement layer, the back-end infrastructure between Visa and merchant acquirers that processes funds after your transaction is approved. This layer is completely invisible to consumers.
Think of settlement as the plumbing behind the wall. It moves funds between financial institutions after the purchase is complete. Consumers never interact with correspondent bank codes or ACH routing numbers in traditional settlement, and they will never interact with USDC or Solana in this program either. Visa is a payment network, not a bank. Its settlement infrastructure changes affect acquirer operations, not cardholder experience.
Is Visa's USDC Settlement on Solana Regulated?
Visa's USDC settlement program on Solana operates within existing regulatory frameworks, though those frameworks involve multiple layers and the US stablecoin regulatory environment was actively evolving as of 2023 to 2024.
USDC is issued by Circle Internet Financial, which maintains money transmission licensing in applicable US states. This is a state-by-state licensing structure, not a single federal license. As of September 2023, Circle's USDC operated under these existing frameworks, and Visa relies on Circle's regulatory standing for the stablecoin component of the settlement program. That introduces a dependency on Circle's ongoing compliance for the program's regulatory foundation.
Visa, as a regulated financial services company, applies its existing compliance infrastructure to the blockchain settlement program. This includes anti-money laundering (AML) screening, know-your-customer (KYC) processes where applicable, and sanctions screening. The program routes settlement funds through a different technical channel than traditional banking, but it does not bypass Visa's compliance obligations in doing so.
The broader US regulatory environment for stablecoins was actively developing at the time of the announcement. Congressional stablecoin legislation was under discussion, and the Office of the Comptroller of the Currency (OCC) had indicated that national banks may engage in certain stablecoin activities under existing legal authorities. The landscape has continued to evolve since September 2023.
Regulatory requirements for stablecoin use in payment settlement are evolving. The regulatory information in this section reflects the landscape as of September 2023. Readers should verify current requirements with qualified legal or compliance counsel.
What's Next for Visa's Blockchain Settlement Program
As of the September 2023 announcement, Visa's USDC settlement program operates with two named acquirer partners, Worldpay and Nuvei, and Visa has not announced plans to extend the program to all merchant acquirers. Sheffield has framed the program as expanding Visa's settlement capabilities rather than replacing fiat settlement. The two systems run in parallel: Visa continues to settle in fiat currency through traditional rails and in USDC on both Ethereum and Solana.
Three observable signals will indicate whether the program deepens: whether additional acquirers join and build the required digital wallet infrastructure; what shape US stablecoin legislation takes and how that affects the program's compliance framework; and whether Visa extends blockchain settlement to additional chains or stablecoins beyond USDC. None of these outcomes are announced. They are the trajectory questions worth watching.
Visa's stablecoin settlement program may have expanded or changed since the September 2023 announcement described in this article. This page will be updated as new information becomes available.
Frequently Asked Questions About Visa USDC Settlement on Solana
What is Visa's USDC settlement on Solana?
Visa announced on September 5, 2023 that it had expanded USDC settlement capabilities to Solana with merchant acquirers Worldpay and Nuvei. The disclosure described mainnet transfers within the settlement workflow and no change to the cardholder experience. Current activity, counterparties, and scale should be verified against Visa's latest information.
Why did Visa choose Solana over Ethereum for USDC settlement?
Visa cited throughput and low costs when announcing Solana as an additional settlement blockchain. The roughly 65,000 TPS figure is theoretical and the USD fee is not fixed. The announcement did not say that Solana replaced Ethereum, and current activity on either network should be verified.
Does Visa using USDC and Solana change how my Visa card works?
No. For Visa cardholders, nothing changes. USDC and Solana operate in the back-end settlement infrastructure between Visa and merchant acquirers, a layer that is completely invisible to consumers. You continue to use your Visa card exactly the same way at checkout. The blockchain settlement happens behind the scenes after your transaction is approved.
Which companies are partnering with Visa for USDC settlement on Solana?
Visa announced the Solana USDC settlement program with two acquirer partners: Worldpay, a major global payment acquirer and processor, and Nuvei, a Canadian fintech company specializing in payment technology for merchants. Both were named in Visa's official newsroom announcement on September 5, 2023.
How fast does USDC settlement on Solana happen compared to traditional settlement?
On-chain confirmation can be faster than traditional batch settlement, but timing depends on Solana's commitment level, network conditions, and the parties' operational controls. The settlement leg described by Visa should not be treated as eliminating every intermediary, conversion step, or counterparty dependency in an end-to-end payment flow.
Was Visa's USDC settlement on Solana a testnet pilot?
Visa's September 2023 announcement described mainnet settlement activity with Worldpay and Nuvei, not merely a testnet demonstration. Because the source is historical, current program activity and scope must be verified rather than assumed.
When did Visa announce USDC settlement on Solana?
Visa announced the expansion of its USDC stablecoin settlement to the Solana blockchain on September 5, 2023, via its official newsroom. The announcement named Worldpay and Nuvei as the acquirer partners for the program.
Is USDC settlement on Solana regulated?
USDC is issued by Circle Internet Financial, which maintains money transmission licensing in applicable US states. Visa applies its existing financial services compliance infrastructure, including AML screening and sanctions controls, to the blockchain settlement program. The US regulatory environment for stablecoins was actively evolving as of 2023 to 2025, with Congressional stablecoin legislation under discussion. Regulatory status may have changed since the September 2023 announcement. Readers should verify current requirements with qualified legal or compliance counsel.
