Some web3 sites like Oasis require Infura to work properly. But there is no reason for which you wouldn't be able to use your own node to serve those requests. Unfortunately, these sites don't let you configure the RPC endpoint they use.
By running liberte, doing some browser and network configuration you can "replace" Infura with your own node.
Usage
Run the gencert.sh script in the cert folder and follow the instructions
Import the generated myCA.pem as certificate authority in your browser
Overwrite the DNS record of Infura (mainnet.infura.io for Ethereum mainnet) to the machine you run liberte on
Build the executable with go build . in the root folder of the repository
Run liberte with root permissions (because it binds to the privileged ports 80 und 443)
You can set your node endpoint via the --node flag of the executable.
