Security Hardening & Faster Loads
Every card key and signature is now checked, the hosted API is locked to the app, and the wallet loads in a fraction of the time.
What's New
- •Card & Signature Checks:Malformed card keys are rejected, and every signature must match the card you connected
- •Locked-Down API:Pricing, swap and NFT services only answer the app itself, and card data is never logged
- •Faster Loading:First load drops from 969 kB to 111 kB, with batched balance and price lookups
- •Clearer Transactions:A review step before you sign, and failed or pending transactions shown as they are
WalletConnect, NFTs & Hosted Pricing
Connect your Burner to any dApp, browse your collectibles, and get live token prices on the hosted app at app.openburner.xyz — plus a refreshed homepage.
What's New
- •WalletConnect:Connect your Burner to any dApp by scanning a WalletConnect QR code
- •NFT Gallery:View, send and receive ERC-721 & ERC-1155 collectibles, with auto-discovery
- •Real-time Pricing:Live token prices via CoinGecko on the hosted app and self-hosted
- •Resilient Connection:Phone-as-reader sessions survive brief drops, so you reconnect without re-scanning
Token Swaps Support
Swap tokens across multiple chains with 0x integration. A small platform fee is included, which helps support the project.
