* Ethereum Sepolia account with some balance <0.01 Eth. Get some [here](https://www.infura.io/faucet/sepolia).
* A password to protect your rln membership.
You can either export the environment variable (keep in mind that this will expose your secrets in your shell history)
```
export ETH_CLIENT_ADDRESS=wss://sepolia.infura.io/ws/v3/YOUR_INFURA_KEY
export ETH_TESTNET_KEY=REPLACE_BY_YOUR_KEY
export RLN_RELAY_CRED_PASSWORD=PICK_A_PASSWORD
```
Or you can use `.env` file - copy the example and edit the variables inside
```
cp .env.example .env
```
**🔑 1. Register RLN membership**
The RLN membership is your access key to The Waku Network. Its registration is done onchain, and allows your nwaku node to publish messages in a decentralized and private way, respecting some [rate limits](https://rfc.vac.dev/spec/64/#rate-limit-exceeded).
