Zipper

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

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.

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.
