The official front end for the Gas Station Network. The staging site is here.
The Gas Station Network is currently deployed to Rinkeby. The addresses are:
| Role | Address | Description |
|---|---|---|
| RelayHub | 0xd216153c06e857cd7f72665e0af1d7d82172f494 | Main RelayHub contract |
| SampleRecipient | 0x9C7bd19648BF9538eE9986b0E2BF18daaA80601c | Example contract that handles meta tx |
| Relay | 0xeE90C66Ed6Aaafbf2DBcd34c84c395905B5C8f20 | Relay deployed to https://rinkeby-01.gsn.openzeppelin.org |
The GSN site can be run locally using just a few commands:
# install dependencies
yarn
# Setup environment variables. See the file for more info.
cp .envrc.example .envrc
# allow environment variables
direnv allow
# Start up the local server
yarn dev
Now navigate to localhost:3000 in your browser. You'll be able to build against test nets such as Rinkeby.
For full control over the smart contracts you'll want to setup the Gas Station Network locally.
Setup a local clone of tabookey-gasless.
Once the dependencies are set up you can run:
./restart-relay.sh
This will start up a local ganache, deploy the contracts, create a sample recipient, and create a relay. You may need to run this command a couple of times; it was a little flakey at the time of this writing.
To mint Ether to yourself on the ganache instance, use the command:
./scripts/ganache-fund.js 10 0x1234...
Replace 0x1234... with your address.
In your browser simply use the network Localhost 8545. You may need to reset the account.
You'll find Tabookey has cleverly deployed consistent addresses.
| Role | Address | Description |
|---|---|---|
| RelayHub | 0xCfEB869F69431e42cdB54A4F4f105C19C080A601 | Main RelayHub contract |
| SampleRecipient | 0x254dffcd3277C0b1660F6d42EFbB754edaBAbC2B | Example contract that handles meta tx |
| Relay | 0xeE90C66Ed6Aaafbf2DBcd34c84c395905B5C8f20 | Relay deployed to http://localhost:8090 |
The app can currently be deployed to Netlify. Url re-write rules are required so that static pages can serve dynamic urls. The url re-write configuration lives in netlify.toml.
To build the production version of the site run:
$ yarn dist
The directory networks contains a configuration file for each network the contracts are deployed to. Network files are named according to the network id: contracts for mainnet live in networks/1.json, contracts for rinkeby live in networks/4.json etc.
Network files are JSON formatted and the expected structure is an array of objects. For example:
[
{
"contractName": "RelayHub",
"address": "0x4FC8ac0210527bCA8c5C66a595Da78B428862276"
}
]
You can add and edit the network config files to add new RelayHubs. Only one RelayHub per network is supported by the application.
