Ledger Plugin Swell

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

Prerequisite

Clone the plugin to a new folder.

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

Then in the same folder clone the app-ethereum.

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

Smart Contracts

Smart contracts covered by this plugin are:

Network	Smart Contract	Smart Contract Address
Ethereum	Deposit Manager & Node Operator Registry	0x46DdC39E780088B1B146Aba8cBBe15DC321A1A1d
Ethereum	rswETH	0xFAe103DC9cf190eD75350761e95403b7b8aFa6c0

Functions implemented:

Function	Selector	Displayed Parameters
addNewValidatorDetails*	0x60ec5216	bytes[] pubkeys
addOperator*	0x54741d6d	string name address operator address reward
deleteActiveValidators*	0xeda74e71	bytes[] pubkeys
deletePendingValidators*	0x242eba0e	bytes[] pubkeys
usePubKeysForValidatorSetup*	0xc3953502	bytes[] pubkeys
deposit	0xd0e30db0	amount stake
disableOperator	0xf56408ed	address operator
enableOperator	0xdd307b99	address operator
initialize	0xc4d66de8	address control_manager
updateOperatorControllingAddress	0x32f73258	address operator address new_operator
updateOperatorRewardAddress	0xe8f28a6c	address operator address reward
updateOperatorName*	0x9f5db69c	address operator string name
withdrawERC20	0xf4f3b200	address token

*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. For addNewValidatorDetails, deleteActiveValidators, deletePendingValidators, usePubKeysForValidatorSetup, plugin can only verify transactions with 4 pubkeys maximum due to memory limitation.

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
