Flow EVM Gateway JSON-RPC Gateway Phase 2 proposal

Grant category

Please select one:

• Open source maintenance
• Developer tools / services
• Educational material

Description

The Ethereum JSON-RPC Specification (https://ethereum.github.io/execution-apis/api-documentation/) is a specification of the standard interface for Ethereum clients.

Problem statement

For the Flow blockchain to achieve EVM compatibility, we need to implement and expose a JSON-RPC API server, which complies to the above specification.

Proposed solution

Build upon the JSON-RPC server implementation in https://github.com/onflow/flow-evm-gateway, and update the mock implementation of certain methods, with the actual business logic needed to provide the expected functionality.

The aforementioned methods include, among others:

• eth_sendRawTransaction
• eth_call
• eth_getLogs
• eth_getTransactionCount
• eth_estimateGas

Impact

Developers not familiar with the Flow blockchain, will be able to tap into its potential, by using their existing knowledge of the Ethereum JSON-RPC API.
