+# Testing with hardware wallets.
+
+## Running the dApp on HTTPS
+
+To test with hardware wallets, the dApp must be served over HTTPS. Run `HTTPS=true npm start` and access it at https://localhost:3000.
+
+### Hardware wallets
+
+## Trezor
+
+To run the trezor hardware wallet emulator, follow these steps:
+
+ 1. [Download and run the trezor bridge](https://github.com/trezor/trezord-go).
+ 2. [Clone the Trezor repo](https://github.com/trezor/trezor-firmware/blob/master/docs/core/build/index.md)
+ 3. [Setup and run the emulator](https://github.com/trezor/trezor-firmware/blob/master/docs/core/emulator/index.md)
+
+Connect to the Trezor in Metamask, and deposit some ether for testing.
+
+## Ledger
+
+We suggest testing with a physical Ledger wallet.
