# Zipper

Deposit/withdraw config and related Zipper reads.

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

```go
config, err := client.Zipper.GetDepositWithdrawConfig(ctx)
if err != nil { log.Fatal(err) }
if err := client.Catalogs.HydrateZipperConfig(config); err != nil {
    log.Fatal(err)
}
```

Client construction starts catalog hydration when `HydrateCatalogs` is enabled. `WaitForCatalogs` returns an error when hydration fails (HTTP/transport error, malformed config, or invalid scales). Call `HydrateZipperConfig` directly for an explicit refresh.

```go
sub, err := client.Zipper.SubscribeZippedAssetSupply(ctx, true)
if err != nil { log.Fatal(err) }
defer sub.Close()
for batch := range sub.Messages() {
	for _, update := range batch.Updates {
		fmt.Println(update.ZippedAssetID, update.Supply)
	}
	break
}
```

With `patchCatalog=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.
