There is a detailed walkthrough on how to build a wallet using the SDK that covers the process in about 20 minutes.

For example, an Independent Project like Vipr was built using the SDK , available on https://github.com/ngutech21/vipr-wallet
Vipr is a modern Progressive Web App (PWA) 📱💻 that functions as an eCash wallet, supporting Nostr-based federation discovery, joining multiple federations, and paying LN invoices via Nostr Wallet Connect.
🔗Test it here: https://beta.vipr.cash/#/

How can one build a LN wallet with the Fedimint Web SDK?
Start by using the create-fedimint-app tool 🛠, which sets up a project with Vite, React, and TypeScript 📝. Then, integrate the @fedimint/core-web package to connect to a federation, manage your balance, and handle payments.
You can send and receive eCash within the federation or use LN for external payments.

The Fedimint Web SDK uses WebAssembly, which helps it run efficiently in browsers and takes care of complex tasks like managing the wallet's state. It supports eCash payments and LN transactions and ensures privacy 🔐. It is also compatible with vanilla JS and frameworks like React ⚛ or Vue 🖼.

2025-05-01 04:20:02 UTC

The Fedimint Web SDK has made it much easier to build Lightning Network (LN) wallets ⚡. This open-source toolkit simplifies creating wallets for fast, private Bitcoin transactions 🛡️. Our goal is to provide the best possible developer experience for building with Bitcoin, lowering the barrier to entry for creating safe, robust, privacy-centric applications.

🔄Accessing funds is also straightforward. Users can redeem eCash tokens anytime to withdraw Bitcoin from the federation’s multisig wallet, keeping Bitcoin within reach.

Note 6 :
🌍Fedimint also enables payments outside the community. A gateway into the Lightning network enables global transactions, allowing members to send or receive Bitcoin worldwide effortlessly.

Within a trusted circle, Fedimint enables instant, off-chain transactions using eCash tokens. This reduces blockchain load, making payments efficient and private for community members—no on-chain fees or delays.

Deposits in Fedimint involve sending Bitcoin to a multisig wallet controlled by guardians. Users receive eCash tokens, backed 1:1 by Bitcoin. Blind signatures ensure privacy—guardians can’t trace tokens, keeping user data hidden.

2025-04-25 10:09:57 UTC

- reply

⚒️ How does guardianship work? Respected community members form a federation, holding multisig keys. A majority must agree to move funds, preventing any single point of failure. Blind signatures keep guardians from accessing individual balances, protecting user privacy.

Fedimint’s community custody builds on social trust. Communities form federations with trusted members, helping make Bitcoin accessible through shared responsibility. It supports regions with limited financial access, fostering local use.

Keeping Bitcoin Within Trusted Circles:
Fedimint Supports Community Custody 🪙 by enabling communities to hold Bitcoin together in a decentralized way. It’s built for trusted circles to help manage funds securely and privately.

Adding @iroh_n0 allows running without a public IP or domain, this unlocks running Fedimint in Node-in-a-Box packages at home such as @npub126n…e9ll 📺Due to upcoming breaking changes on Iroh we recommend only using it on Signet (to be stabilized in v0.8).

Recurring payment support has been a much requested feature for a while now, while integrators could already implement it, we now have an officially supported way of generating LNURLs and receiving recurring payments.

Let's dive into the highlights!🔥
The new UI allows running a Fedimint as a single binary again without orchestrating multiple services! The setup process has also been simplified and should be more stable now.
