INTU NODE SIGNER

An INTU account is essentially an MPC account that the user or users run on their own devices.
Any device that runs Javascript can be a signer on an INTU Account.

In the most common case, we can use a server to run a listener on the bloockchain and co-sign with our user(s). Participating in the MPC process and co-signing transactions with them.

The benefit on these co-signers is that you can add additional logic to the co-signer before they participate in the signing process with the end user. The co-signer could also be a proposer of transactions - it is a truly equal participant in the INTU Account.

Here is a publically available codebase for a node signer: https://github.com/intu-labs/intu_node_signer

The important parts to update are the private keys (and keep track of the public key for the signer to pass to your frontend) and an RPC endpoint.
