invalid public key input:', <solana.account.Account object at 0x7f34954d5f40>

[hemantsirsat]

I was implementing a buy function using pyserum and solana using the following code.

        payer=sender_keypair.public_key,
        owner=Account(sender_keypair),
        side=Side.BUY,
        order_type=OrderType.LIMIT,
        limit_price=0.5,
        max_quantity=abs(1),
        opts=TxOpts(skip_preflight=True)
    )

The following error occurs:

ValueError: ('invalid public key input:', '<solana.account.Account object at 0x7fac2a7c2cd0>')

[leofisG]

what is sender_keypair ?

Sender_keypair(<class 'solana.keypair.Keypair'>) is the keypair of the owner's wallet.

[leofisG]

can you also include the code snippet on how you read from that? Omit the actual key of course

Interesting, let me take a closer look.

something like this change could work, that's all because in site-packages/solana/rpc/api.py", line 1059, in send_transaction     txn.sign(*signers) signers should be Keypair, not Account, this is a recent change https://github.com/michaelhly/solana-py/commit/4fcf707e593702940ce517f92244f5ea91bdf7ac

probably better to patch market and the other libs to use Keypair instead of Account ?

[hemantsirsat]

I tried changing public_key() to public_key of pyserum/market.py and pyserum/core.py. Now there's a new error. pyserum/market/core.py line 149, in _prepare_order_transaction raise ValueError("Invalid payer account. Cannot use unwrapped SOL.") ValueError: Invalid payer account. Cannot use unwrapped SOL.

[Imaclean74]

First attempt at replacing Account with Keypair in the PR referenced above

[vikulikov]

in _prepare_order_transaction raise ValueError("Invalid payer account. Cannot use unwrapped SOL.") ValueError: Invalid payer account. Cannot use unwrapped SOL. `

I believe it happens due to payer == SOL unwrapped public address. Does anybody know how to handle it? Or it is a bug? How can I trade instruments with SOL (such as selling SOL/USDC or buying SRM/SOL) in this case?

Did you find any solution?

[Imaclean74]

is this still failing with the latest release ?

[hemantsirsat]

invalid public key input is solved. Although there's a new error. ValueError: Invalid payer account. Cannot use unwrapped SOL.

I'm also getting this same issue still. #95 looks to be a fix for this so I'm waiting for that.

Turns out my issue can be fixed by simply settling funds before placing an order. Btw the payer account is your token account address, not your public key if you aren't dealing with SOL or USDC I think.

I'll show this with an example using the ATLAS/USDC pair

Say I want to buy the asset using USDC, I take my USDC address as the payer. If I wanted to sell the asset then the payer would be the address of the asset. This likely won't work if the payer address is your SOL wallet which will give the ValueError you got. If you want to buy something using SOL then idk how you would go about doing that. I just get my token address from raydium, you might want to instead do that by code.

atlas_market_address = PublicKey("Di66GTLsV64JgCCYGVcY21RZ173BHkjJVgPyezNN7P1K") # ATLAS/USDC
usdc_wallet = PublicKey("ANDAfNfg...13UG6PWd") # USDC
atlas_market = Market.load(cc, atlas_market_address)
atlas_market.place_order(payer=usdc_wallet,owner=Keypair(privateKey),order_type=OrderType.LIMIT,side=Side.BUY,limit_price=0.1,max_quantity=1,opts=TxOpts(skip_confirmation=False))
