provides a reference implementation of the FireFly Connector API (FFCAPI)\nfor EVM Based blockchains.\n\nSee the [Hyperledger Firefly Documentation](https://hyperledger.github.io/firefly/latest/overview/public_vs_permissioned/#firefly-architecture-for-public-chains)\nand the [FireFly Transaction Manager](https://github.com/hyperledger/firefly-transaction-manager) repository for\nmore information.\n\n\u003e Also see [firefly-ethconnect](https://github.com/hyperledger/firefly-ethconnect) for the hardened\n\u003e connector optimized for private Ethereum sidechains, optimized for finality assured consensus\n\u003e algorithms and throughput.\n\n# License\n\nApache 2.0\n\n## ABI Encoding\n\nA key responsibility of the FFCAPI connector is to map from developer friendly JSON inputs/outputs\ndown to the binary encoding of the blockchain.\n\nThis repo uses the Apache 2.0 RLP encoding/decoding utilities from the\n[firefly-signer](https://github.com/hyperledger/firefly-signer) repository.\n\n## Configuration\n\nFor a full list of configuration options see [config.md](./config.md)\n\n## Example configuration\n\n```yaml\nconnectors:\n- type: ethereum\n  server:\n    port: 5102\n  ethereum:\n    url: http://localhost:8545\n```\n\n## Blockchain node compatibility\n\nFor EVM connector to function properly, you should check the blockchain node supports the following JSON-RPC Methods over HTTP:\n### Event tracking\n- `eth_blockNumber`\n- `eth_newBlockFilter`\n- `eth_getFilterLogs`\n- `eth_getFilterChanges`\n- `eth_getBlockByHash`\n- `eth_getLogs`\n- `eth_newFilter`\n- `eth_uninstallFilter`\n- `eth_getTransactionByHash`\n- `eth_getTransactionReceipt`\n\n### Query\n- `eth_call`\n- `eth_getBalance`\n- `eth_gasPrice`[^1]\n  \n### Transaction submission\n- `eth_estimateGas`\n- `eth_sendTransaction`\n- `eth_getTransactionCount`\n- `eth_sendRawTransaction`[^2]\n\n\n[^1]: also used by Transaction submission if the handler is configured to get gas price using \"connector\".\n\n[^2]: only required by custom transaction handlers that supports pre-signing.\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhyperledger%2Ffirefly-evmconnect","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fhyperledger%2Ffirefly-evmconnect","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhyperledger%2Ffirefly-evmconnect/lists"}
