ICP Now Accepted at 137 Swiss Supermarkets. Here's How It Actually Works

Internet Computer Protocol (ICP) and ckBTC are now accepted as payment methods at more than 137 SPAR supermarkets across Switzerland, serving a customer base of 1.4 million people. The integration, carried out by Swiss crypto payment specialist DFX through the OpenCryptoPay platform, went live this month. 

How Does Crypto Payment Work At SPAR Switzerland?

The payment process works through a QR code displayed at the checkout. A customer scans the code with their mobile device, approves the transaction through their crypto wallet, and the payment completes within seconds. DFX receives the crypto from the customer and immediately pays the equivalent amount in Swiss francs directly to SPAR, meaning the retailer never holds crypto on its books.

The system supports over 30 different crypto wallets and is designed to feel as familiar as existing mobile payment tools.

As André Scherrer, Managing Director of SPAR Switzerland, stated: "For customers, payment is just as intuitive as TWINT or Apple Pay. That's important, so payments with crypto truly become suitable for daily life."

What Is ckBTC?

ckBTC (chain-key Bitcoin) is a Bitcoin-backed token that runs natively on the Internet Computer blockchain. Unlike wrapped Bitcoin products on other chains, ckBTC does not rely on bridges or third-party custodians. It is minted and redeemed directly on the ICP network using chain-key cryptography, which is a method that lets ICP smart contracts hold and sign transactions on external blockchains. This makes it faster and cheaper to use than bridged Bitcoin alternatives.

Why Did SPAR Switzerland Choose Crypto Payments?

The decision came from SPAR Handels AG in 2024, driven partly by a desire to reduce dependence on major payment acquirers. Traditional point-of-sale (POS) payments involve card networks and payment service providers (PSPs), each taking a cut of every transaction.

Crypto payments cut out those intermediaries. DFX charges a transaction fee of just 0.20%, which is significantly lower than standard PSP fees in retail.

Scherrer explained: 

"I'm convinced that cryptocurrencies are going to become much more significant as a payment method in retail over the next few years, also because they make retailers less dependent on the major acquirers."

How Back-Office Processing Works

One of the practical challenges of crypto payments at retail scale is accounting reconciliation. SPAR addressed this by working with Matchbox, a software solution from Swiss firm treibauf that SPAR already used for financial reconciliation.

Matchbox was extended to handle crypto as a new payment type. It automatically matches crypto payment data from the POS with the transaction list from DFX, including the 0.20% fee, and posts everything to SPAR's internal accounts without manual intervention.

Cyril Thommen, CEO of DFX, described the goal as: 

"A set-up that's so simple, everyone can operate it intuitively. That goes for the payment process at the cash register just as much as processing the crypto payments in the back office."

What Is The Broader Context For ICP Right Now?

The SPAR rollout adds real-world transaction volume to the Internet Computer network at a time when the DFINITY Foundation is actively trying to increase on-chain usage as part of its economic strategy.

In January 2026, DFINITY founder Dominic Williams published a white paper titled "Mission 70 and Accelerating the Internet Computer Economy." The document outlines a plan to reduce ICP token inflation by at least 70% by the end of 2026, bringing it down from 9.72% in January 2026 to 2.92% by year-end.

The strategy has two parts:

• Supply-side reductions (targeting a 44% drop): lower voting rewards, a revised dissolve-delay bonus structure, reduced rewards for older Gen-1 node hardware, and a cap on the total voting reward pool.
• Demand-side acceleration (targeting a 26% drop): more ICP burned through higher network usage, which is where real-world integrations like the SPAR rollout directly contribute.

What Is ICP Inflation And Why Does It Matter?

ICP, like many proof-of-stake networks, mints new tokens to reward participants who lock up their holdings to vote on governance proposals and to pay node providers who run the network's infrastructure. When the network was launched at genesis in May 2021, these rewards were set high to attract early participants who faced long lockup periods with limited liquidity.

DFINITY's position is that those incentives are no longer necessary at the same level, and that continuing to mint at the current rate dilutes existing holders without adding proportionate value to the network. Mission 70 is the structured response to that imbalance.

Conclusion

ICP is now accepted at over 137 SPAR Switzerland locations, with near-zero fees, no bridging infrastructure, and automated back-office reconciliation built in from day one. The integration covers both ICP and ckBTC, using chain-key technology to settle transactions natively on the Internet Computer without custodians or wrapped token intermediaries. 

At the network level, DFINITY is working to cut ICP inflation by more than 70% before the end of 2026, with increased real-world usage forming a direct part of that economic equation.
