Lava “providers” serve RPC traffic for supported chains and are not typical full nodes. You run the lavap process, point it at your own backend nodes (or trusted endpoints), and then stake to make the service public.

​
Prerequisites

  • Linux host with the Lava binaries (at least lavap) installed.
  • A synced backend node for each chain you plan to serve.
  • A Lava wallet funded with LAVA tokens.

​
1) Create a provider config

Example: Lava testnet provider (lava-provider.yml) and Ethereum provider (eth-provider.yml). Adjust hosts/ports to your setup. 
# lava-provider.yml
endpoints:
  - api-interface: tendermintrpc
    chain-id: LAV1
    network-address:
      address: 127.0.0.1:2224
      disable-tls: true
    node-urls:
      - url: ws://127.0.0.1:26657/websocket
      - url: http://127.0.0.1:26657
  - api-interface: grpc
    chain-id: LAV1
    network-address:
      address: 127.0.0.1:2224
      disable-tls: true
    node-urls:
      url: 127.0.0.1:9090
  - api-interface: rest
    chain-id: LAV1
    network-address:
      address: 127.0.0.1:2224
      disable-tls: true
    node-urls:
      url: http://127.0.0.1:1317

# eth-provider.yml
endpoints:
  - api-interface: jsonrpc
    chain-id: ETH1
    network-address:
      address: 127.0.0.1:2223
      disable-tls: true
    node-urls:
      url: wss://your-ethereum-node/ws/

​
2) Start the provider

# Replace --from with your wallet name; pick the correct Lava chain-id
# lava-mainnet-1 for mainnet, lava-testnet-2 for testnet
screen -S lava-provider
lavap rpcprovider lava-provider.yml --from <wallet_name> --geolocation 1 --chain-id lava-testnet-2 --log_level debug
You can run multiple configs (e.g., Ethereum) in separate terminals.

​
3) Pre-flight test (before staking)

lavap test rpcprovider --from <wallet_name> --endpoints "<ENDPOINTS>"

​
4) Stake the provider (make it public)

# Stake a single service; amounts and geolocation depend on chain specs
lavap tx pairing stake-provider <CHAIN_ID> <AMOUNT> <ENDPOINT ...> <GEO> <VALIDATOR> --chain-id lava-testnet-2
A new stake applies at the next epoch (about 30 blocks).

​
5) Verify

List providers for a chain: 
lavap query pairing providers "<NETWORK_NAME>" --node "<LAVA_RPC_NODE>"

​
Notes

  • TLS and lavavisor are recommended for production deployments.
  • Use the official Supported Chains list to ensure your api-interface/endpoints match each spec.
