Kingstown, St. Vincent & the Grenadines, August 31st, 2026 - ChangeNOW has selected Qastle Wallet, the quantum-secured multi-chain wallet developed by Krown Technologies, as an early participant in its Fast Track Program. The integration embeds ChangeNOW exchange infrastructure inside Qastle, giving users access to swap functionality, fiat on- and off-ramping, and support for more than 1,500 assets across 90+ networks.
Krown Technologies positions its stack as a natively quantum-secured Web3 ecosystem. That stack includes the Krown Network Layer 1 blockchain, Qastle Wallet, decentralized trading and digital ownership tools, real-world asset infrastructure and a slate of Web3 applications. Qastle is presented as the first hot wallet to combine Post-Quantum Cryptography (PQC) with Quantum eMotion's QRNG2 quantum random number generator for enhanced entropy and resistance to classical and quantum attacks.
Qastle supports the creation of new wallets and the import of existing Web3 wallets. Importantly, only wallets created inside Qastle benefit from QEM's QRNG2-generated entropy for key material; imported wallets retain their original security profile. From a functionality standpoint, Qastle offers the common wallet operations of sending, receiving, trading and staking assets, and it is designed to work across major blockchain networks rather than being limited to the Krown ecosystem.
The ChangeNOW integration is intended to expand Qastle's operational reach. Per the announcement, Qastle users will be able to access ChangeNOW's support for more than 90 networks and 1,500 assets and perform swaps inside the wallet without having to switch to external applications. The integration also aims to provide a streamlined path between the native KROWN token and fiat currencies through embedded fiat on- and off-ramping.
"Were pleased to welcome Qastle Wallet, a quantum-secure wallet from the Krown ecosystem, to the ChangeNOW Fast Track Program. Were committed to supporting promising projects, particularly those that already have a strong track record of building and delivering real products. By integrating ChangeNOWs exchange infrastructure with Qastle Wallet and expanding access to KROWN, were helping remove friction for users and make their experience more seamless, while supporting the wallets growth and wider adoption."

The Fast Track Program itself is an integration initiative intended to help wallet providers embed exchange services into their user experience. ChangeNOW supplies an exchange API to participants with an initial revenue share starting at 0.4% of the total exchange volume generated through the wallet interface. The API is described as engineered for reliability, carrying a 99.99% uptime metric and a response time of 350 milliseconds. Participants are supported by 24/7 account management coverage.
As part of the program, ChangeNOW also coordinates marketing and public exposure for participating wallets. Program benefits listed in the announcement include marketing across crypto media with a stated reach of over 10 million, amplification via ChangeNOW's social channels with a combined audience exceeding 100,000, and placements at Tier-1 industry conferences where average attendance is noted to exceed 15,000 people.
Application volume to the Fast Track Program is deliberately managed to preserve integration quality. The program takes on only three to four wallets per month to ensure both technical and marketing stability. Wallet projects seeking to join are asked to apply via the Fast Track Program page, providing contact information including an email, the project's website and an additional contact handle such as Telegram or X.
ChangeNOW and Qastle plan continued collaboration beyond the technical integration. The teams have outlined co-marketing work across social channels and public relations coverage in crypto outlets to increase visibility. The announcement also notes a set of activities planned around TOKEN2049 in Singapore, scheduled for October 7 to 8, 2026, where Qastle will be featured within ChangeNOW's presence at the event.
The integration embeds ChangeNOW infrastructure into a wallet built around a visible quantum-security narrative. For ChangeNOW, the partnership extends the reach of its Fast Track Program into a wallet that emphasizes quantum-resistant security features. For Qastle and Krown, the integration delivers on-wallet access to a broad asset set, swap capabilities and fiat rails that are designed to reduce the need for users to leave the wallet environment in order to exchange tokens or convert to and from fiat currencies.
ChangeNOW is described in the announcement as an enterprise-focused crypto super app offering tools for companies to accept payments, exchange and manage digital assets, and integrate Web3 finance into operations. Among the capabilities highlighted for business partners are an API, exchange widget, white-label implementations and an affiliate program, with partner revenue sharing that starts at 0.4% per swap.
The announcement lists a range of sectors that use ChangeNOW's services, including FinTech, iGaming, lending and investment businesses, and states that the platform facilitates tens of millions of successful transactions every month for partners. The announcement also references past partnerships with recognizable names in the crypto space.
