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 🖼.

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.
