Registration / Funding (GRT)

In order to participate in the testnet, you'll need Goerli ETH and GRT. To be eligible for testnet GRT, you'll need to
  1. 1.
    join The Graph Discord,
  2. 2.
    get the @testnetindexer role in the #roles channel,
  3. 3.
    use the #testnet-goerli-faucet channel to obtain testnet GRT.

Approving And Staking

Via Graph Explorer
The Graph Explorer provides an easy way to approve and stake your GRT as an indexer via a web GUI.
  1. 1.
    Navigate to the testnet explorer​
  2. 2.
    Login with Metamask and select the Goerli network
  3. 3.
    Navigate to your profile (click your address/avatar at top right)
  4. 4.
    Select the Indexing tab and hit the Stake button
  5. 5.
    Follow the directions on the staking screen to stake the desired amount

Via the Contracts CLI

To approve your testnet GRT to be spent through the staking contract, first approve it in the GRT contract:
git clone https://github.com/graphprotocol/contracts
cd contracts
​
# If you haven't done this before:
npm install
npm run compile
​
./cli/cli.ts -m <indexer-mnemonic> -p <ethereum-goerli-node> \
contracts graphToken approve --account 0x35e3Cb6B317690d662160d5d02A5b364578F62c9 --amount <grt>
Afterwards, stake this amount:
./cli/cli.ts -m <indexer-mnemonic> -p <ethereum-goerli-node> \
contracts staking stake --amount <grt>

Setting An Operator

Via Graph Explorer
  1. 1.
    Navigate to the testnet explorer​
  2. 2.
    Login with Metamask and select the Goerli network
  3. 3.
    Navigate to your settings page (click profile dropdown at top right and select ⚙️ Settings)
  4. 4.
    Navigate to the Operators settings (click Operators button)
  5. 5.
    Click + to add your operator wallet address
  6. 6.
    Follow instructions to submit transaction

Via the Contracts CLI

./cli/cli.ts -m <indexer-mnemonic> -p <ethereum-goerli-node> \
contracts staking setOperator --operator <operator-address> --allowed true
