Generalized EIP-3074 Invokers.

• BaseInvoker - Invoker template for building arbitrary Invoker logic.
• BatchInvoker - Invoker with batch transaction support.

Developing with these contracts currently requires foundry-alphanet – a repository containing patches for Foundry to support EIP-3074 opcodes.

We have abstracted foundry-alphanet docker image execution into a set of Makefile scripts listed below.

First, we will need to set up the submodules for the repository.

make install

We can build the contracts using forge build via foundry-alphanet:

make cmd="forge build"

We can run tests using forge test via foundry-alphanet:

make cmd="forge test"

We can launch an Anvil instance using anvil via foundry-alphanet:

make cmd="anvil"

Below, we will deploy the BatchInvoker contract to a local Anvil network.

First, we will need to launch an Anvil instance. If you are deploying to a launched network, you can skip this step.

make cmd="anvil"

Deploy the BatchInvoker contract to the network.

make cmd="forge script Deploy --sig 'deploy()' --rpc-url $RPC_URL --private-key $EXECUTOR_PRIVATE_KEY --broadcast"

We can test the BatchInvoker by sending a transaction via the contract.

make cmd="forge script Executor --sig 'sendEth(address,address,uint256)' $INVOKER_ADDRESS 0x3074ca113074ca113074ca113074ca113074ca11 0.01ether --rpc-url $RPC_URL --broadcast"
