scroll-server

A server for the scroll client (Clash Royale 2.0.1306, iOS). Takes a real client from TCP connect to the lobby: login, own home data, chests, card upgrades, the shop.

Requirements

Rust 1.75+
PostgreSQL 16

Running

createdb scroll

cargo run --release -p scroll-server

Listens on 0.0.0.0:9339, the port the client hardcodes. The schema is created on first boot. DATABASE_URL defaults to postgres:///scroll.

On macOS a Homebrew cluster may need LC_ALL=C to start at all.

Services can also run separately:

cargo run --release -p auth-service
cargo run --release -p game-service
cargo run --release -p gateway

Checking it without a phone

scroll-probe speaks the same protocol and prints the decoded lobby:

cargo run --release -p gateway --bin scroll-probe -- 127.0.0.1:9339

Flags: --claim-free-chest, --buy-chest <name>, --desync. Pass an account and pass token to reconnect as an existing player: scroll-probe 127.0.0.1:9339 0 1 <passtoken>.

Pointing a client at it

The client hardcodes game.clashroyaleapp.com. Patch that string in the binary inside the ipa to your machine's address, keeping the 23 byte slot NUL padded so nothing around it moves.

Configuration

variable	default
`DATABASE_URL`	`postgres:///scroll`
`SCROLL_GATEWAY_LISTEN`	`0.0.0.0:9339`
`SCROLL_CSV_ROOT`	`assets`
`SCROLL_SHOP`	`config/shop.json`
`SCROLL_STARTER_PROFILE`	built in
`RUST_LOG`	`info`

Shop

config/shop.json lists what the server sells, as Name#count:

{
  "offers": [
    { "id": 1, "give": "Gold#1000" },
    { "id": 5, "give": "chest:Gold#1" },
    { "id": 7, "give": "Diamonds#500", "cost": "Gold#20000" }
  ]
}

Names resolve against the csv tables. cost is optional; without it the server charges the same price the client computes from the game data.
