Yes, based on available information, swa.btc (from platforms like Swapin or BTC Stamps) can typically be withdrawn to a Bitcoin wallet and converted to native BTC via redemption on the protocol (check swapin.com for exact steps, as it involves bridging and burning wrapped assets).
This implies trading BTC into swa.btc is possible in the reverse—wrap BTC into swa.btc for use on Stacks or related chains.
How: Use a supported wallet/exchange (e.g., Xverse or Leather) to wrap BTC to swa.btc via the protocol's bridge, or trade on DEXs like Velar on Stacks. For precise instructions, refer to official docs at btcstamps.com or swapin.com, as processes may vary. Not financial advice—verify fees and risks.
