Some of its components are in the process of refinement and preparation for community access. +This project is an experimental reference implementation and is considered complete for its intended purpose. While it may undergo minor updates to address any critical issues that may arise, no major changes are expected in the near future. + +### Component Overview + +The following is a list of the main components included of this project. Some of these, while dev complete, are possibly subject to limitations or known issues that are highlighted in a separate section of this document. -### Component Overview and Status +1. **EVM Interoperability Service**: This service enables flows to execute asynchronous EVM transactions and calls, waiting for the result. -The following is a list of components included in this project. All of these are subject to future changes and are currently under development. +2. **Identity Module**: This module allows for the configuration of the EVM identity a flow will operate with. It also supports the implementation of custom identity modules leveraging Hardware Security Modules (HSMs) or other protocols to ensure the safety of the private key used for signing EVM transactions. The reference `UnsecureRemoteEvmIdentityFlow` allows you to specify the private key and RPC endpoint and is only meant as a reference for implementing safer options. -1. **EVM Interoperability Service**: This service enables flows to execute asynchronous EVM transactions and calls, waiting for the result. It is fully implemented and tested. +3. **Web3 Interfaces**: Current implementation supports direct interaction with ERC20 tokens, standard Web3 APIs like querying blocks and transactions, the EVM `SwapVault` contract which allows swapping ERC20, ERC721, ERC1155 assets against a Corda asset. -2. **Identity Module**: This module allows for the configuration of the EVM identity a flow will operate with. It also supports the implementation of custom identity modules leveraging Hardware Security Modules (HSMs) or other protocols to ensure the safety of the private key used for signing EVM transactions. The basic module is fully implemented and tested, and other modules are being implemented. +4. **Atomic Swap Flows**: Atomic swap flows for executing Corda-EVM DvP and PvP have been implemented. A sample project with tests demonstrates how an EVM asset is swapped with a Corda asset in a completely fair, risk-less, balanced way. -3. **Web3 Interfaces**: Current implementation supports interaction with ERC20 tokens and standard Web3 APIs like querying blocks and transactions. These features are fully implemented and tested. Support for ERC721 and ERC1155 tokens is in the pipeline and will be added soon. +5. **Event Subscription Service**: there is no real, full support in this project for event subscription but rather a simplistic, incomplete interface for doing so. Triggering flows in response to EVM events can be done using existing projects like [Eventeum](https://github.com/eventeum/eventeum) or Web3 javascript frameworks like [Web3.js](https://web3js.org) or [Ethers.js](https://ethers.org) -4. **Atomic Swap Flows**: Basic atomic swap flows for executing Corda-EVM DvP and PvP scenarios are under active development. +6. **Patricia Merkle Trie Component**: Allows EVM events and transaction validation, production of events and transaction proofs, and verification of proofs. -5. **Event Subscription Service**: This component is responsible for subscribing to and handling events. It is currently under active development and nearing completion. Some features are experimental and will be moved to a separate external module in future iterations. +7. **EVM / Solidity Project for Atomic Swap**: This project will implement atomic swap of EVM assets like ERC20, ERC721, ERC1155. -6. **Patricia Merkle Trie Component**: This upcoming component will support EVM events and transaction validation, production of events and transaction proofs, and verification of proofs. +## Known Issues and Limitations -#### Coming Soon +### Memory Storage / Persistence +Some services required by the application use memory storage for simplicity rather than persistent storage. Persistent storage is necessary to retain references to transactions and associated data (e.g., signatures, identity) between distinct flows. For non-experimental use, persistent storage is required. -7. **Full Atomic Swap Flows**: Full atomic swap flows for executing Corda-EVM DvP and PvP scenarios are in the pipeline and will be implemented in the near future. +### Nonce +The EVM transaction model uses the account nonce to maintain the order and uniqueness of transactions originating from a specific Ethereum address. The nonce represents the number of transactions sent from that address and ensures that transactions are executed in the correct sequence and not replayed. While the EVM interface available from the flows handles the asynchronous model of EVM transactions and calls, it lacks a recovery function should any issue arise with the nonce that is not already handled by the underlying Web3j framework. -8. **EVM / Solidity Project for Atomic Swap**: This project will implement atomic swap of EVM assets like ERC20, ERC721, ERC1155, with live upgradeability to extend with other assets. It is in finalization phase and will be released soon. +### Checkpointing +While some further testing and investigation are required, Corda flows' checkpointing may, in some cases, cause an EVM transaction to be repeated. For non-experimental use, proper deduplication of the EVM interface calls should be ensured. -## Experimental Code +### EVM Events +The EVM interface, implemented as a Corda service, has a very simplistic and incomplete event registration mechanism. It is not intended for use outside of highly experimental cases, and we recommend that events be registered, filtered, and handled outside of a Corda node functioning as a coordination mechanism used to trigger related flows on Corda nodes. -Please note that this project currently contains some experimental code, particularly related to EVM events subscription and handling. This code is intended to be moved to an external module in the future. +### Tests and Test Network +Integration tests rely on a local Hardhat node instance running and initialized with a deployment script that deploys the required contracts. This implies that accounts, keys, and addresses used by the integration tests are hardcoded in a base class used by all the tests. -## Integration Tests +#### Manual Test Network Setup +Please refer to the EVM project's README.md for instructions in this regard before executing any Corda project test. +#### Docker Test Network Setup +The Corda project has Gradle tasks meant to start a Docker container with the test network ready for executing the integration tests included in the projects. -The integration tests in this project are currently hardcoded to a locally set up test EVM instance.
