Description
The Wesatoshis journey began three years ago with a solo founder leveraging 20 years of expertise in reverse engineering and hacking. Later, my good friend Yossi joined the adventure, bringing his deep passion for Bitcoin and helping guide the project forward. Together, we fully embraced our vision in full time . At first, we didn’t have a concrete product idea, but we knew one thing: building an SPV client for embedded chips was essential—a challenging and exciting goal.
While developing the SPV client, we explored various applications, experimenting with ideas like Bitcoin tip boxes, NFT authentication scanners, lottery machines, and blockchain watches. However, none of these fully justified the need for a Bitcoin SPV client.
Then, 2024 arrived, and Bitcoin’s Layer 2 solutions gained significant momentum. We seized the opportunity and chose to integrate with the most secure Layer 2: Rootstock (RSK). We applied for and received a grant, which gave us the resources to purchase 3D printers and dive into designing PCB boards with relentless passion, free from budget worries. More importantly, the grant signified that the Rootstock team believed in the future of our product.
The most difficult challenge? Getting the firmware to work flawlessly on Arduino. After countless hours of focused, nonstop development support from rootstock developers , we achieved a stable beta release—and we were thrilled with the results.
Introducing Wesatoshis
Wesatoshis is the first hybrid hardware wallet that operates entirely independently of mobile or desktop apps. This innovative card enables you to pay Lightning invoices using RBTC without the hassle of channel management or liquidity concerns. Here’s how it works:
- The card locks your RBTC in a smart contract.
- A random Lightning wallet, integrated with NOSTR, monitors the invoice and pays it on your behalf.
- These wallets earn a commission for processing the transaction.
With RBTC, the card’s built-in SPV wallet allows you to seamlessly pay invoices, send and receive BTC, and peg in and out of RBTC.
But it doesn’t stop there—Wesatoshis integrates with Tropekus DeFi and Money On Chain, transforming the card into a personal financial hub. Through these integrations, you can borrow, lend, and swap for stablecoins, creating a complete ecosystem of financial functionality.
In one sentence: Wesatoshis is the first portable, native Bitcoin bank—empowering you to do anything you want with Bitcoin, wherever you are.
And this is just the beginning.
Why We’re Launching Builder Activation
We plan to invest in a fiber laser engraver to offer custom engravings on the card’s metal surface. Supporters of the project will be able to personalize their cards with unique designs. Additionally, 10% of the funds raised will be awarded to the designer of the most popular engraving, as voted by the community.
Mission
Our mission is to build a fully decentralized, no-KYC, portable Bitcoin companion that empowers users to perform any Bitcoin-related operation—without reliance on mobile apps (Google, Apple) or desktop software.
