My question seems pretty trivial but why doesn't ChipMixer adopt Segwit yet? It was activated such a long time ago and even if they had planned to use Legacy from a long time ago, it seems like it would be better to have some mix of bc1 and p2pwsh addresses in the chips?
The last thing I read about it:
last few days some of low size chips were preloaded with Segwit (segwit over p2sh) instead of non-segwit (p2pkh). Out of all withdrawn Segwit chips - none were sweeped by our users. If you were affected - please contact our support - we will help you get your coins.
ChipMixer Segwit rollout will be delayed.
I haven't imported SegWit private keys in a long time, but last time I did it was a bit more complicated than native addresses:
For P2SH-P2WPKH addresses (Addresses starting with "3")Just add
p2wpkh-p2sh: directly in front of your private key.
For example
p2wpkh-p2sh:5BitcoinPrivateKey
This should generate the corresponding p2wpkh-p2sh bitcoin address.
For P2WPKH addresses (Bech32, starting with 'bc1')This time we'll add
p2wpkh: in front of the private key.
For example
p2wpkh:5PrivateKey
This should generate the corresponding Bech32 address
