Ledger Direct Connectivity for dApps
summary
Ledger sells over 8 million devices and secures roughly 20% of crypto assets and now offers Ledger wallet button — a drop‑in web component that gives direct connectivity to devices via USB/Bluetooth using EIP193 and EIP‑6963, retrieves accounts from Ledger sync, broadcasts transactions, and performs ERC‑7730 clear‑signing checks. The underlying Device Management Kit (DMK) replaces LedgerJS, supports EVM only today across ~14 networks, is live in production (RC11), can install the Ethereum app inline, and has $4,000 and $1,000 hackathon bounties.
