Ethereum transaction submitter using Nym

This library provides functionality for submitting Ethereum transactions using the Nym mixnet.

It has two components:

• client: sends transactions to submit to a server over the Nym network
• server: recieves transactions from clients and submits them to Ethereum

Requirements

• rust 1.25.1
• Nym (see build instructions here).

Usage

Run Nym websockets client

Both the client and server require a Nym websockets client to connect to.

To run one, go to your nym dir:

./target/release/nym-client init --id <your-id>
./target/release/nym-client run --id <your-id>

Build

git clone https://github.com/noot/nym-ethtx.git
cd nym-ethtx
cargo build --release

Network

By default, this library uses a local Ethereum chain (http://localhost:8545). However, it also supports mainnet and Goerli with the --network or -n flags.

Client

The client by default uses the server with Nym address HGLX5467Kr8hHaYENr8meY3KDH5BozVQRR8XTBD8UseB.Fdnv3igmSrGcUZSA4bUyqa6adyHKjZGyhFnnkWMJsGAt@62Lq9D5yhRVXyeHrBjqoQMg3i9aVTJY7nQSnB74VH31t. If this isn't available, you'll need to run a server or find one to send the request to.

The client requires a (hex-encoded) Ethereum private key to sign the transaction. The app looks for this key by default in the file client.key. You can also specify the file with --key or -k.

For example, to send ether:

./target/release/client --to=0x1EA777Dc621f5A63E63bbcE4fc9caE3c5CDEDAFB --value=0.1 --network=goerli
# Sep 24 18:37:37.106  INFO client: signed transaction 0xbe292c8e43d775ef8ec58f974e6403317efdcdc0a09ed8232238dd8bea44ac10

The to address can also be an ENS address:

./target/release/client --to=address.eth --value=0.1 --network=goerli
# Sep 24 18:37:37.106  INFO client: signed transaction 0x0958489d9ab18796439ed38c8028421899125d11fd6ef917118343b5ab7370e3

Server

./target/release/server
# Sep 24 18:41:28.450  INFO server: listening on DXHLCASnJGSesso5hXus1CtgifBpaPqAj7thZphp52xN.7udbVvZ199futJNur71L3vHDNdnbVxxBvFKVzhEifXvE@5vC8spDvw5VDQ8Zvd9fVvBhbUDv9jABR4cXzd4Kh5vz
