Encrypting RPC Server

This server is using Gnosis Chain Configuration and Shutter Network Mempool encryption to protect your transactions against MEV.

Requirements

To deploy and use for requests other than eth_sendRawTransaction

• Ganache >= 7.0.0
• Foundry >= 0.2.0

To start and build the server:

• Docker

How to run example

1. First you need to use below command to get submodules: git submodule update --init
2. Start a ganache server by: ganache -b 5 -t 2021-12-08T20:55:40 --wallet.mnemonic brownie
3. Deploy contracts in /src folder by using: make compile-contracts && make deploy
4. Build the container image: docker build . -t encrypting-rpc-server
5. Run the server: docker run -p 8546:8546 encrypting-rpc-server --signing-key bbfbee4961061d506ffbb11dfea64eba16355cbf1d9c29613126ba7fec0aed5d --key-broadcast-contract-address {KEY_BROADCAST_CONTRACT_ADDRESS} --sequencer-address {SEQUENCER_CONTRACT_ADDRESS} --keyper-set-manager-address {KEYPER_SET_MANAGER_CONTRACT_ADDRESS} --rpc-url http://host.docker.internal:8545

Contract addresses can be obtained from gnosh-contracts/broadcast/deploy.s.sol/1337/run-latest.json. There are CREATE transactionType and select contractName as what you need then you have the contractAddress.

There are other options you can use like:

• rpc-url: RPC URL from alchemy/infura or other providers. Default: http://localhost:8545
• http-listen-address: Which address this server runs. Default: :8546
• keyper-set-change-look-ahead: How much ahead your transactions should be revealed.
• For running the server with prometheus metrics enabled, use metrics-port, metrics-host and metrics-port
• wait-mined-interval can be used to update the time delay for inclusion checks.
• dbUrl it is the url of postgres database, to record transactions and encrypted transactions.
