When you participate in Stacking, you must provide a rewards address where your earnings will be delivered. The type of address depends on how the pool or delegate handles payout:

• Bitcoin address — Used when rewards are distributed in BTC (e.g., solo Stacking, or some pooled Stacking setups where the user registers a BTC payout address).

• Stacks address — Used when the protocol converts BTC rewards into STX and distributes them natively on the Stacks chain.

How Leather helps:

• If the pool requires a Bitcoin address, Leather will prompt you to register one (often through a payout hints contract).

• If STX is used for rewards, Leather automatically recognizes your built-in Stacks address.

It’s important to know which address is in use:

• If BTC is sent to an incorrect address, it cannot be recovered

• If no address is registered, you may miss your payout or default to STX if the protocol allows it

Check your pool’s documentation and confirm your reward settings before committing STX to a cycle.
