Run SUAVE Locally

You can use suave-geth to start a local SUAVE devnet.

There are two ways to work with suave-geth:

  1. ⚡ Install the latest release binary
  2. 🧙‍♀️ Build from source

Latest release binary​

curl -L https://suaveup.flashbots.net | bash

Start your local devnet with:

suave-geth --suave.dev
Using --suave.dev will run suave-geth with the following flags:
./build/bin/geth --dev --http --http.addr "0.0.0.0" --http.api "suavex,debug,suavey,eth" 

--http.corsdomain "*" --http.vhosts "*" --ws --ws.addr "0.0.0.0" --ws.origins "*" 

--keystore "/tmp/suave-dev/keystore" --unlock "0xB5fEAfbDD752ad52Afb7e1bD2E40432A485bBB7F" 

--password "/tmp/suave-dev/password.txt" --miner.gaslimit "30000000"

Building from source​

info

We recommend that you use Golang v1.21 or newer.

Clone the suave-geth repository:

git clone git@github.com:flashbots/suave-geth.git
cd suave-geth

Build the binary:

make suave

Start the local devnet with:

./build/bin/suave-geth --suave.dev

You can check that the suave binary is available in ./build/bin/ with:

./build/bin/suave-geth --version
Missing packages

If you have set up a new machine to run through this, you'll also need to install Make and Go: 

sudo apt install make golang-go

Testing the devnet​

Compile the example contracts:

What is Forge?

forge is a part of the smart contract development toolchain we use in our examples, which you can learn more about in our next tutorial. If you do not have it installed, you can do so quickly with: 

curl -L https://foundry.paradigm.xyz | bash

cd suave && forge build

Create a few example transactions:

go run devenv/cmd/main.go

Execute a RPC request with curl like this:

curl 'http://localhost:8545' --header 'Content-Type: application/json' --data '{ "jsonrpc":"2.0", "method":"eth_blockNumber", "params":[], "id":83 }'

If you built from source (but not if you're running Docker), you can attach to the usual Geth javascript console to get any interactive data you need with:

./build/bin/suave-geth attach /tmp/geth.ipc
IPC not found

It may be the case, especially if you have a custom GOPATH, that the geth.ipc is somewhere else. You can either force the path using the --ipcpath flag when starting SUAVE, or find the path in the logs (it could look something like /System/Volumes/Data/private/var/folders/rt/gq5bhvy17wz5z5dl32_x83dw0000gp/T/geth.ipc, for instance).

From within the console, you can run:

eth.accounts[0]

This should return "0xb5feafbdd752ad52afb7e1bd2e40432a485bbb7f" - the default funded account for local development.

eth.getBalance(eth.accounts[0])

Should return a really large number 1.1579...e+77. If you try eth.getBalance("<your_new_address>") instead, you should see 0.

If you try:

web3.eth.blockNumber

It should tell you the block height of your local network.

What am I actually running?​

The main actor in the SUAVE protocol is called a "Kettle". Kettles house all components necessary to perform confidential compute.

Here is the architecture of a Kettle on the Toliman Testnet. When you start a local SUAVE devnet, you're running all the stuff in the purple square (but not the domain specific services, i.e. nodes connected to other chains from/to which you wish to receive or send bundles).

Architecture

You can read more about exactly what a Kettle contains in architecture section of the Technical Specs.
