Wallet Direct Connectivity
summary
Ledger Button provides an EIP-1193 provider (v1.1.1) that connects Nano Gen 5 over USB or Bluetooth and fetches accounts, signs transactions and personal messages, and broadcasts txns; it runs as a Lit web component so it injects into any DApp without extensions. Clear signing renders human‑readable JSON on device and the system runs transaction simulation checks to flag suspicious payloads. The stack includes Device Management Kit, Signer Kits for Ethereum/Bitcoin/Solana/Cosmos, Ledger Sync, and a live 1inch swap demo. USB and BLE transports EIP-1193 provider
