zk.money does not work with MetaMask + local node

[the-metalworker]

Expected Behaviour

I expect to be able to use MetaMask with my locally synced Ethereum mainnet full node and to connect zk.money Aztec dapp with no issues.

Current Behaviour

I use MetaMask with a full node running on my local desktop. When I try to connect to zk.money I get an error that says I am on the wrong network, although my local node is running Ethereum mainnet and is fully synced. Most other dapps work with this setup, Aztec is one of the few that does not recognize localhost in MetaMask as a valid network.

Steps to Reproduce (for bugs)

1. Sync Ethereum full node on local desktop
2. Go into MetaMask and configure to connect to your locally running full node
3. Try to connect to zk.money Aztec dapp
4. See error message about wrong network
