i'm trying to (eventually) add liquidity to the Liquidity Baking CPMM contract on Granadanet. In order to add liquidity, I need some tzBTC from the tzBTC contract here.. I cannot, for the life of me, call the tzBTC contract and get some tzBTC using the tezos-client.

It's not clear to me which entrypoint will give my wallet tzBTC, so I've tried calling mintOrBurn, transfer and approve.

Could someone please explain which entrypoint I need to call in order to get tzBTC, and explain how they know that/what they are looking at (so I can learn).

Also I'm using the tezos-client CLI and I'm having a bear of a time properly formatting my args when calling entrypoints, if someone could paste the tezos-client call I need to make I would be incredibly grateful.

Only admin can call mintOrBurn in that particular contract. As you can see in the contract storage, tz1KqTpEZ7Yob7QbPE4Hy4Wo8fHG8LhKxZSx is the admin, so you need a private key from this address.

Fortunately, tz1KqTpEZ7Yob7QbPE4Hy4Wo8fHG8LhKxZSx is one of the bootstrap addresses with known private key edsk3gUfUPyBSfrS9CCgmCiQsTCHGkviBDusMxDJstFtojtc1zcpsh, which can be imported to tezos-client and used to play with liquidity baking in granadanet.

I'm not a tezos-client guru, but I think the args should look like this:

tezos-client ... --entrypoint 'mintOrBurn' --arg 'Pair 100 "tz1blablabla..."'

  • hey this is very helpful, thank you. How do I use that known private key? I tried downloading a json wallet file from the faucet, and swapping the secret for the private key you gave and the pkh for tz1KqTpEZ7Yob7QbPE4Hy4Wo8fHG8LhKxZSx, but I get and error Invalid activation file: No case matched: Missing object field activation_code At /secret: Unhandled error (Invalid_argument "Hex.to_char: 107 is an invalid char")

    You don't need to activate already existing bootstrap account. You need this: tezos.stackexchange.com/a/1839/53
