Clef Tutorial

initialization

First, you need to init clef dir to create masterseed

# CLEFDIR - directory with clef data (default: $HOME/.clef)
clef init --configdir CLEFDIR

"Unlocking" keystore

Then you should COPY your keystore file to keysotre folder and add password to clef

cp keystoreFile KEYSTOREDIR
clef setpw --configdir CLEFDIR 0x123dead #password will prompted and decrypted by masterseed

Rules

To accept or reject some requests create rule file:

function ApproveListing() {
    return "Approve"
}
function ApproveTx(){
        return "Approve"
}

and then add checksum of rules file to clef

clef attest --configdir CLEFDIR $(sha256sum rules.js)

Start service

clef --configdir CLEFDIR --keystore KEYSTOREDIR --chainid=35441 --rules=/data/rules.js

then you can use clef as signer in geth

geth ...YOUR FLAGS... --signer=CLEFDIR/clef.ipc

More info about clef can be found in the offcial docs.
