Lockin.wtf [[email protected] TICKET #2057]
Lockin.wtf is a decentralized application (dApp) that allows you to view and manage your token holdings on the Solana blockchain.
Easily connect any Solana wallet supported by @solana/wallet-adapter, such as Phantom and Backpack. The dApp auto-connects to your wallet if it has been previously approved, enhancing user convenience.
To ensure security, the dApp requests a signature to validate wallet ownership upon connection. This signature process is client-side and safe, with no blockchain interaction.
Once your wallet is connected, the dApp fetches and displays detailed information about the tokens in your wallet. This includes:
- Fetching and parsing token accounts
- Retrieving token metadata, including name, symbol, and logo
- Calculating the USD value of your tokens using Jupiter Swap prices
- Displaying the tokens in a user-friendly interface
All actions are performed using official Solana libraries such as @solana/web3.js and the Metaplex library.
To handle rate limits and ensure smooth operation, the dApp uses Bottleneck for rate limiting API calls to Solana RPC endpoints and other services.
The dApp uses Tailwind CSS and daisyUI for a flexible and rapid development experience. You can easily customize the theme by modifying the daisy.themes setting in ./tailwind.config.js and setting the data-theme attribute in the <html> tag. Additionally, a theme switcher is provided for users to toggle between dark and light modes.
For feedback on on-chain actions, the dApp integrates react-hot-toast.
