Stacks (STX) is the native token of the Stacks layer, which anchors smart contract activity to Bitcoin. Traders swap STX to participate in Stacks-based applications or to move value in and out of the Bitcoin-connected ecosystem. Because STX runs on its own dedicated network, routing and address setup deserve a quick check before confirming any exchange.
Before swapping STX, confirm that your receiving wallet or platform supports the STX network specifically, as there is only one supported network for this asset. Crucially, the STX network requires an Extra ID — an additional identifier similar to a memo or destination tag — when sending to certain addresses, particularly custodial exchange deposit addresses. Check whether your destination platform provides an Extra ID alongside the deposit address; if it does, include it exactly as shown, since omitting or mistyping it can result in delayed or unrecoverable funds. Confirmation times on the STX network can vary depending on network conditions, so treat any estimate as approximate. Zest displays the full rate and recipient details before you confirm, giving you a chance to verify the address and Extra ID before the swap is submitted.

Requires Extra IDWhere an extra identifier such as a memo or tag is required, enter it exactly when the receiving platform asks for one — transfers without it can be delayed or lost.
