Hi,
If I have WBTC on ETH network, then I use curve.fi to swap WBTC from Ethereum network to BTC network, is the swap info, btc destination address and/or other info stored in any database or even in the main ETH network?
Same question can be done in a BTCB to BTC swap info with binance bridge.
Thank you.
The above options are possible, but you may have to pay a certain fee.
Are you looking for anonymity in WBTCs? I would argue that the exchange between WBTC and BTC only provides temporary anonymity since those are two different public chains. Sign up for an account and deposit your Bitcoins on a Bitcoin mixer for legal privacy. This solution can be more economical and simpler than the one you mentioned above.
