After creation, you need to register it as a Relayer to Poly net and get consensus nodes approving your registeration. And then you can send transaction to Poly net and start relaying.\n\nAfter that, make sure you already have a MultiversX wallet with EGLD.\n- [Docs](https://docs.multiversx.com/wallet/web-wallet/)\n\nBefore running, you need feed the configuration file `config.json`.\n\n```\n{\n  \"ElrondConfig\": {\n    \"ElrondChainID\": \"\",\n    \"ElrondTxVersion\": 1,\n    \"ElrondBlockMonitorIntervalInSeconds\": 6,\n    \"BlocksPerBatch\": 15,\n    \"ElrondForceHeight\": 0,\n    \"RestURL\": \"https://gateway.elrond.com\",\n    \"SideChainID\": 100,\n    \"CrossChainManagerContract\": \"\",\n    \"BlockHeaderSyncContract\": \"\",\n    \"KeyStorePath\": \"\",\n    \"KeyStorePwdSet\": {\n      \"\": \"\",\n    }\n  },\n  \"PolyConfig\": {\n    \"ChainID\": 2,\n    \"RestURL\": \"http://beta1.poly.network:20336\",\n    \"EntranceContractAddress\": \"0300000000000000000000000000000000000000\",\n    \"OntUsefulBlocksNum\": 1,\n    \"WalletFile\": \"./wallet.dat\",\n    \"WalletPwd\": \"\",\n    \"PolyStartHeight\": 0,\n    \"PolyMonitorIntervalSeconds\": 10\n  },\n  \"BoltDbPath\": \"./db\",\n  \"RoutineNum\": 10,\n  \"TargetContracts\": [\n    {\n      \"0xD8aE73e06552E...bcAbf9277a1aac99\": {\n        \"inbound\": [6],\n        \"outbound\": [6]\n      }\n    }\n  ]\n}\n```\n\nNow, you can start relayer as follow:\n\n```shell\n./elrond-polychain-relayer --cliconfig=./config.json \n```\n\nIt will generate logs under `./Log` and check relayer status by view log file.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmultiversx%2Fmx-chain-polychain-relayer","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmultiversx%2Fmx-chain-polychain-relayer","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmultiversx%2Fmx-chain-polychain-relayer/lists"}
