Ledger Hardware Wallet Ethereum Web3 subprovider

Package Exports

  • @ledgerhq/web3-subprovider

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@ledgerhq/web3-subprovider) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

IMPORTANT: this package is deprecated due to the fact we had to move away from U2F. Contributions are welcome to make it running in WebUSB!
