Ledger ENS Plugin

This is a plugin for the Ethereum application which helps parsing and displaying relevant information when signing a ENS smart contract.

Prerequisite

Clone the plugin to a new folder.

git clone https://github.com/libertify/ledger-plugin-ens.git

Then in the same folder clone the app-ethereum.

git clone --recurse-submodules https://github.com/LedgerHQ/app-ethereum.git     #app-ethereum

Multicall*	0xac9650d8	bytes calls

*For renewAll, ENS plugin will only support signing transactions with 2 names maximum. For multicall, ENS plugin will only support signing transactions with 3 calls maximum. For strings and byte arrays bigger then 32, plugin is showing the first and last 16 bytes in "16...16" format, due to memory limitations.

Build

To build the plugin, go to your folder with Ethereum app and plugin. Open a new terminal window and run:

sudo docker run --rm -ti -v "$(realpath .):/app" -v "$(realpath app-ethereum):/plugin_dev/app-ethereum" --user $(id -u $USER):$(id -g $USER) ghcr.io/ledgerhq/ledger-app-builder/ledger-app-dev-tools:latest

In the container, go to the plugin repository, then to the tests/ folder.

cd ledger-plugin-swell/tests
./build_local_test_elfs.sh

Tests

To test the plugin go to the tests folder from the "ledger-plugin-swell" and run the script "test"

cd ledger-plugin-swell/tests         # go to the tests folder in ledger-plugin-swell
yarn test                       # run the script test
