A modular, developer-friendly Typescript Bundler for Ethereum EIP-4337 Account Abstraction
Run with one-liner:
curl -fsSL https://skandha.run | bashor follow steps below:
- install all dependencies by running
yarn - build
yarn build && yarn bootstrap cp config.json.default config.json- edit
config.json - (optional) run local geth-node from
test/geth-dev - run
./skandha - Skandha will run for all chains available in
config.json - Networks will be available at
http://localhost:14337/{chainId}/(e.g. for devhttp://localhost:14337/1337/)
cp config.json.default config.json- edit
config.json docker build -t etherspot/skandha .docker run --mount type=bind,source="$(pwd)"/config.json,target=/usr/app/config.json,readonly -dp 14337:14337 etherspot/skandha start
- Unsafe mode - bypass opcode & stake validation
- Redirect RPC - Redirect ETH rpc calls to the underlying execution client. This is needed if you use UserOp.js
--unsafeMode- enables unsafeMode--redirectRpc- enables redirecting eth rpc calls
