# Zipper

Deposit/withdraw config and related Zipper reads.

`client.zipper` exposes route configuration and live zipped-asset supply updates.

```rust
let config = client.zipper.get_deposit_withdraw_config().await?;
client.catalogs.hydrate_zipper_config(&config)?;
```

With `hydrate_catalogs` enabled, construction inside Tokio hydrates catalogs in the background; otherwise `wait_for_catalogs().await?` starts hydration on the current runtime. `wait_for_catalogs().await?` **errors** when hydration fails (use `catalogs_last_error()` to inspect). Prefer the typed `hydrate_zipper_config` helper; no consumer `serde_json` dependency is required.

```rust
let mut sub = client.zipper.subscribe_zipped_asset_supply(true).await?;
if let Some(batch) = sub.recv_result().await? {
    for update in batch.updates {
        println!("{} {}", update.zipped_asset_id, update.supply);
    }
}
```

With `patch_catalog=true`, supply events update the shared catalog before delivery. The stream is public. Route config is not a fee quote; quote immediately before an on-chain withdrawal and enforce a maximum fee/slippage.
