Prover Network: Key Setup

The prover network uses Secp256k1 keypairs for authentication, similar to Ethereum wallets. You may generate a new keypair explicitly for use with the prover network, or use an existing keypair.

You do not need to hold any funds in this account, it is used solely for access control.

Generate a Public Key​

Prover network keypair credentials can be generated using the cast CLI tool.

First install Foundry:

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

Upon running this command, you will be prompted to source your shell profile and run foundryup. Afterwards you should have access to the cast command.

Use cast to generate a new keypair:

cast wallet new

which will give you an output similar to this:

The "Address" what you should submit in the form, in the example above this is 0x552f0FC6D736ed965CE07a3D71aA639De15B627b. The "Private key" should be kept safe and secure. When interacting with the network, you will set your SP1_PRIVATE_KEY environment variable to this value.

Retrieve an Existing Key​

If you already have an existing key you would like to use, you can also use cast retrieve your address:

cast wallet address --private-key $PRIVATE_KEY
