Make sure to download, build and have the cardano-http-bridge running on port 1337.
$ git clone git@github.com:input-output-hk/cardano-http-bridge.git
$ cd cardano-http-bridge
$ git submodule update --init --recursive
$ cargo run --release -- start --port 1337
NOTE:
cargois the Rust package manager / build assistant (~stackin Haskell).
Give it a bit of time (~30 minutes to an hour) to sync with mainnet, downloading blocks
and epochs from peers (this should create a .hermes folder on your $HOME that contains
a bunch of serialized files).
This is just plain stack
$ stack build --fast --exec "stack exec -- cardano-minimal-viable-wallet-exe"
