W-Pay was initially inspired by the Lightning Network and was launched in early 2015 following a rebrand of e-coin. The service was founded in 2013 as the first mass consumer service in the world to successfully combine cryptocurrency networks with traditional banking services and the Visa card scheme.


On Chain VS Off Chain

At the heart of all Wirex services, the W-Pay technology continues to evolve, making it possible to use over 50 cryptocurrencies together with Fiat money in a fully-automated and trustless environment, without the need to wait for blockchain confirmations.

We are constantly adding new liquidity providers, with over $1 billion in value of transactions processed in the OTC market.

How W-Pay Works

Wirex Payment Network

  • Liquidity Providers
  • PSD2 integration
  • Banks
  • Payment processing
  • Visa network
  • Security
  • Multi-crypto blockchain connections

Network participants establish a bidirectional payment channel by placing funds into a multisignature “channel” address. Once the channel is established, counterparties can start exchanging payments.

The current balance is stored as the most recent transaction signed by both parties. To make a payment, both parties sign a new exit transaction spending from the channel address.

The network does not require cooperation from the counterparty and both sides can exit the channel based on agreed rules of the system. Once the channel is closed, final balances are broadcast to the blockchain.

W-Pay enables new levels of transaction between parties that were previously impossible via financial systems vulnerable to monopolisation. Without the need for custodial trust and ownership, participation on the network can be dynamic and open for all.

W-Pay Features


Multi-blockchain / multi-asset. Support for numerous cryptocurrencies (Bitcoin, Litecoin, Ether, Ripple, Dash, NEM etc.) as well as Fiat money (US Dollars, GBP, Euros, Japanese Yen, etc.) The network supports most digital assets and is seamlessly integrated with the Visa network. Such a unique blend allows our partners to implement complex money flows, which were previously not possible for consumer personal finance.


Security. Built on a state-of-the-art platform specifically designed to deliver fast and secure payment solutions. Connected to multiple blockchains as well as traditional payment schemes. Designed in accordance with ISO 20022 and PCI/DSS standards.


Instant payments. Capacity to process millions of payments without a need for custodians. Bidirectional payment channels allow network participants to pay each other off-chain and only broadcast net positions to the network based on their business rules. This model allows instant and cheap payments in a trustless environment.


Integration options. Multiple options for deep integration depending on the type of network participant (Liquidity Provider, Merchant or End User); from cross blockchain integration to simple REST API.

Visa network. Deep integration with the Visa card network brings digital assets to traditional payment infrastructure. It’s now possible to use digital assets in more than 40M merchants in 210+ countries. As of mid-2017 Wirex has issued more than 700K cards for customers in 130+ countries.


Payment Service Directive (PSD2). Payment Service Directive (PSD2). PSD2 is a game changer in European retail banking. Under PSD2 (starting January 2018), new rules will enable third parties to access payment account information and initiate payments on behalf of the user via PISP (Payment Initiation Service Provider). Wirex is working hard to obtain its PISP license as soon as it becomes available to allow us to bring banking deposits into the W-Pay network.

W-Pay Infrastructure

We’ve built 100% of our platform in house. We own the full technology stack, giving us the flexibility to react to changes in customer behaviour and demands. This unique approach enables Wirex to build systems free from legacy constraints by using blockchain technology that is revolutionising the payment industry; making transactions faster, more secure and more cost effective for everyone. W-Pay provides access to a multi-asset global network of liquidity providers which trades in a fully automated and transparent environment.
