    Hey! There is a 
    Wallet.sign_message_using_p2pk
    which should do the job.
  • g
    v0.23.0 is out - https://github.com/ergoplatform/sigma-rust/releases/tag/ergo-lib-v0.23.0 /cc @Ilya | Spectrum included are fixes for bugs preventing parsing of those two blocks.

    @mohammmad The new version of wasm-bindgen is out. I updated https://github.com/ergoplatform/sigma-rust/pull/682 and it's green! Please check out the published alpha version of ergo-lib with weak-ref enabled.
  • g
    Great timing! I just started to descent into the rabbit hole of making wasm-pack to use custom wasm-bindgen version. 🙂
  • m
    Hmm, you are lucky 😅 I will check the alpha version as soon as I find some free time.
  • s
    if there's anything specific we should be aware of could you please add to this issue: https://github.com/ergoplatform/ergo-lib-wasm/issues/31
  • g
    Nothing comes to mind. I'm going through https://github.com/tc39/proposal-weakrefs to figure out how this magic box works. 🙂

    @greenhat is it feasible to have an optional parameter on 
    Wallet.sign_transaction()
    signalizing what inputs we want to sign? I need this to implement 
    sign_tx_input
    for EIP-12. Example:
    Copy code
    ts
wallet.sign_transaction(
  context, 
  unsignedTx, 
  unspentBoxes, 
  dataInputBoxes, 
  [0, 2] // only signs inputs 0 and 2 from unsignedTx, others will be bypassed and not reduced
);
  • g
    Do you mean the prover should skip the rest of the inputs and put an empty proof in the resulted signed tx?
  • g
    *empty proof for those skipped inputs
  • c
    Correct
  • g
    Would it be better to make a new API to sign just an input? Similar to sign_transaction but having unsigned input as a parameter instead of unsigned tx, and returning a signed input. I mean we're not signing the whole transaction anymore.
  • c
    Works good to me 🙂
  • g
    I'll get to it first thing tomorrow morning. It should be easy.
  • s
    Hey @greenhat , If you have the time could you please have a look at this one: https://github.com/ergoplatform/ergo-lib-wasm/pull/32 It's just wasm bindings for 
    sigma-ser
    , I have a need for it in my ergo hack project 🙂
