Only required if connecting to a substrate chain.\n\n\n## Building\n\n`make build`: Builds `chainbridge` in `./build`.\n\n**or**\n\n`make install`: Uses `go install` to add `chainbridge` to your GOBIN.\n\n## Docker \nThe official ChainBridge Docker image can be found here.\n\nTo build the Docker image locally run:\n\n```\ndocker build -t chainsafe/chainbridge .\n```\n\nTo start ChainBridge:\n\n``` \ndocker run -v ./config.json:/config.json chainsafe/chainbridge\n```\n\n# Configuration\n\n> Note: TOML configs have been deprecated in favour of JSON\n\nA chain configurations take this form:\n\n```\n{\n \"name\": \"eth\", // Human-readable name\n \"type\": \"ethereum\", // Chain type (eg. \"ethereum\" or \"substrate\")\n \"id\": \"0\", // Chain ID\n \"endpoint\": \"ws://:\", // Node endpoint\n \"from\": \"0xff93...\", // On-chain address of relayer\n \"opts\": {}, // Chain-specific configuration options (see below)\n}\n```\n\nSee `config.json.example` for an example configuration. \n\n### Ethereum Options\n\nEthereum chains support the following additional options:\n\n```\n{\n \"bridge\": \"0x12345...\", // Address of the bridge contract (required)\n \"erc20Handler\": \"0x1234...\", // Address of erc20 handler (required)\n \"erc721Handler\": \"0x1234...\", // Address of erc721 handler (required)\n \"genericHandler\": \"0x1234...\", // Address of generic handler (required)\n \"maxGasPrice\": \"0x1234\", // Gas price for transactions (default: 20000000000)\n \"gasLimit\": \"0x1234\", // Gas limit for transactions (default: 6721975)\n \"gasMultiplier\": \"1.25\", // Multiplies the gas price by the supplied value (default: 1)\n \"http\": \"true\", // Whether the chain connection is ws or http (default: false)\n \"startBlock\": \"1234\", // The block to start processing events from (default: 0)\n \"blockConfirmations\": \"10\" // Number of blocks to wait before processing a block\n \"useExtendedCall\": \"true\" // Extend extrinsic calls to substrate with ResourceID. Used for backward compatibility with example pallet. *Default: false*\n \"egsApiKey\": \"xxx...\" // API key for Eth Gas Station (https://www.ethgasstation.info/)\n \"egsSpeed\": \"fast\" // Desired speed for gas price selection, the options are: \"average\", \"fast\", \"fastest\"\n}\n```\n\n### Substrate Options\n\nSubstrate supports the following additonal options:\n\n```\n{\n \"startBlock\": \"1234\" // The block to start processing events from (default: 0)\n}\n```\n\n## Blockstore\n\nThe blockstore is used to record the last block the relayer processed, so it can pick up where it left off. \n\nIf a `startBlock` option is provided (see [Configuration](#configuration)), then the greater of `startBlock` and the latest block in the blockstore is used at startup.\n\nTo disable loading from the blockstore specify the `--fresh` flag. A custom path for the blockstore can be provided with `--blockstore `. For development, the `--latest` flag can be used to start from the current block and override any other configuration.\n\n## Keystore\n\nChainBridge requires keys to sign and submit transactions, and to identify each bridge node on chain.\n\nTo use secure keys, see `chainbridge accounts --help`. The keystore password can be supplied with the `KEYSTORE_PASSWORD` environment variable.\n\nTo import external ethereum keys, such as those generated with geth, use `chainbridge accounts import --ethereum /path/to/key`.\n\nTo import private keys as keystores, use `chainbridge account import --privateKey key`.\n\nFor testing purposes, chainbridge provides 5 test keys. The can be used with `--testkey `, where `name` is one of `Alice`, `Bob`, `Charlie`, `Dave`, or `Eve`. \n\n## Metrics\n\nSee [metrics.md](/docs/metrics.md).\n\n# Chain Implementations\n\n- Ethereum (Solidity): [chainbridge-solidity](https://github.com/ChainSafe/chainbridge-solidity) \n\n The Solidity contracts required for chainbridge. Includes deployment and interaction CLI.\n \n The bindings for the contracts live in `bindings/`. To update the bindings modify `scripts/setup-contracts.sh` and then run `make clean && make setup-contracts`\n\n- Substrate: [chainbridge-substrate](https://github.com/ChainSafe/chainbridge-substrate)\n\n A substrate pallet that can be integrated into a chain, as well as an example pallet to demonstrate chain integration.\n\n# Docs\n\nMKdocs will generate static HTML files for Chainsafe markdown files located in `Chainbridge/docs/`\n\n`make install-mkdocs`: Pull the docker image MkDocs\n\n`make mkdocs`: Run MkDoc's docker image, building and hosting the html files on `localhost:8000` \n\n# Testing\n\nUnit tests require an ethereum node running on `localhost:8545` and a substrate node running on `localhost:9944`. E2E tests require an additional ethereum node on `localhost:8546`. \n\nA docker-compose file is provided to run two Geth nodes and a chainbridge-substrate-chain node in isolated environments:\n```\n$ docker-compose -f ./docker-compose-e2e.yml up\n```\n\nSee [chainbridge-solidity](https://github.com/chainsafe/chainbridge-solidity) and [chainbridge-substrate-chain](https://github.com/ChainSafe/chainbridge-substrate-chain) for more information on testing facilities.\n\nAll Go tests can be run with:\n```\n$ make test\n```\nGo tests specifically for ethereum, substrate and E2E can be run with\n```\n$ make test-eth\n$ make test-sub\n$ make test-e2e\n```\n\n# ChainSafe Security Policy\n\n## Reporting a Security Bug\n\nWe take all security issues seriously, if you believe you have found a security issue within a ChainSafe\nproject please notify us immediately.
