🛠️ Account Abstraction Playground

Runs off-chain services on a local anvil chain to help test 4337 functionality.

🖥️ Running locally

Running the devnet

1. copy docker-compose.devnet.yaml and .env.devnet to your repo

2. Run services

docker compose -f docker-compose.devnet.yaml --env-file ./.env.devnet up

This will:

1. ⛓️ Start anvil instance at http://0.0.0.0:8545, chainId = 31337
2. 🛠 Deploy required contracts
3. 📡 Launch the following bundler services against anvil node
   • skandha (TypeScript, by etherspot.io)
   • transeptor-bundler (TypesScript, by Transeptor Labs)
   • [COMING SOON 🔜] rundler (Rust, by Alchemy)
     • Note: Rundler doesn't support unsafe mode yet, avoid using until this issue is closed
4. 🌍 Set up a nginx reverse proxy at http://0.0.0.0:3010 with the following services:

📡 Services

Service	Direct URL	Proxy URL
Anvil RPC (chainId: 31337)	http://0.0.0.0:8545	http://0.0.0.0:3010/anvil-rpc
