Can I sign contract deployment transactions using Ledger hardware wallet?

[andreibancioiu]

Yes! 🚀

For example:

mxpy contract deploy --proxy=https://devnet2-gateway.multiversx.com --recall-nonce \
 --bytecode=counter.wasm --gas-limit=5000000 \
 --ledger --ledger-address-index=42 --send

Example of such a transaction on Devnet 2.

Thanks a lot

can we have this in the mxpy CLI cookbook? I see it mentioned in the documentation, but maybe it would be nice to explain better what --ledger-address-index=42 parameter is.

@razvanphp, yes, thanks for the suggestion 🙏

We have prepared a PR on docs, currently under internal review:

multiversx/mx-docs#725

@FabriceDautriat, @razvanphp, thank you 🙏
