ChangeNOW’s Fast Track Program Welcomes New Participant: Qastle Wallet
Kingstown, St. Vincent & the Grenadines, August 31st, 2026, Chainwire
ChangeNOW Fast Track Program welcomes Qastle Wallet, bringing 1,500+ assets, 90+ networks and fiat access to the quantum-secured Krown ecosystem. ChangeNOW has selected Qastle Wallet, the quantum-secured multi-chain wallet from Krown Technologies, as one of the first participants in its new Fast Track Program. Through the integration, Qastle users will gain access to ChangeNOW’s infrastructure features such as integrated swaps and fiat on- and off-ramping. For KROWN users in particular, the integration is expected to create a simpler route between the KROWN token and other major digital assets and traditional currencies without requiring them to leave the wallet.
An Overview of Qastle Wallet and the Krown Ecosystem
Krown Technologies has built a natively quantum-secured blockchain ecosystem designed to bring post-quantum protection into everyday Web3 infrastructure. Its ecosystem spans the Krown Network Layer 1 blockchain, Qastle Wallet, decentralized trading, digital ownership, real-world asset infrastructure and Web3 applications.
At the heart of this ecosystem is Qastle, the world’s first quantum-secured hot wallet. The wallet combines Post-Quantum Cryptography (PQC) and Quantum eMotion’s QRNG2 technology, a true-entropy quantum random number generator designed to resist both classical and quantum attacks.
The wallet allows users to import an existing Web3 wallet or create a new one. However, only new wallets created in Qastle use QEM’s QRNG2 technology for added security, while imported ones keep their original security level. From there, Qastle combines familiar wallet functionality like sending, receiving, trading, and staking. It also operates as a multi-chain wallet, allowing users to manage assets across major blockchain networks rather than limiting them to the Krown ecosystem.
The ChangeNOW partnership adds other pieces to that usability story. Through the integration, Qastle users will gain access to 90+ supported networks and 1,500+ assets, as well as swap functionality, meaning they will now move assets between networks without switching to outside apps. Users will also have a simpler route between KROWN (the native token) and fiat currencies, including fiat on-ramping and off-ramping. For their part, ChangeNOW gets its infrastructure embedded inside a wallet built around a visible quantum-security blockchain ecosystem and extends the reach of its Fast Track Program.
We’re pleased to welcome Qastle Wallet, a quantum-secure wallet from the Krown ecosystem, to the ChangeNOW Fast Track Program. We’re committed to supporting promising projects, particularly those that already have a strong track record of building and delivering real products. By integrating ChangeNOW’s exchange infrastructure with Qastle Wallet and expanding access to KROWN, we’re helping remove friction for users and make their experience more seamless, while supporting the wallet’s growth and wider adoption.

What is the Fast Track Program
The Fast Track Program is a ChangeNOW integration initiative designed to help crypto wallets expand their functionality, improve user access to digital-asset exchange services, and create new revenue opportunities through embedded swap infrastructure.
It does this by offering wallets a ChangeNOW exchange API integration with a starting revenue share from 0.4% of the total exchange volume generated through their interface. The API is built for reliability, with a 99.99% uptime rate and a response time of 350 milliseconds, and comes with 24/7 support from a dedicated account manager.
In addition, ChangeNOW runs the marketing side across crypto media outlets with 10M+ reach and its own social channels with a combined audience of 100k+. Participants also get a presence at Tier-1 industry conferences, where average attendance exceeds 15,000 participants.
How to Join the Program
Applications to the program are open but limited. Only three to four wallets get a chance to be onboarded in a month to ensure technical and marketing stability. Interested wallet projects can submit their applications on the Fast Track Program page by providing an email, the project’s website, and an additional contact (e.g., Telegram, X, and so on).
What’s Next for ChangeNOW and Qastle Wallet
The ChangeNOW and Qastle Wallet partnership doesn’t stop at this announcement. The two teams are planning co-marketing across several social media pages and PR coverage across crypto outlets to raise visibility. There will also be a series of activities around TOKEN2049 in Singapore (October 7 to 8, 2026), which will feature Qastle within ChangeNOW’s presence at the event and put it in front of one of the industry’s most important global audiences.
