• 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

Utilize the JSON-RPC server implementation of the go-ethereum client, and setup the relevant eth namespace with the required RPC methods (github.com/ethereum/go-ethereum/rpc). A draft PoC with this can be found here: onflow/flow-evm-gateway#10

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.

1 - Mock Implementation	Provide a mock implementation of the endpoints described in issues: onflow/flow-evm-gateway#1 / onflow/flow-evm-gateway#2 / onflow/flow-evm-gateway#3 / onflow/flow-evm-gateway#4 / onflow/flow-evm-gateway#5 / onflow/flow-evm-gateway#6 / onflow/flow-evm-gateway#7 / onflow/flow-evm-gateway#8 / onflow/flow-evm-gateway#9 . In this context, mock means that we do not yet have the indexer & storage services to serve real data.	4 weeks	-	6500 $
