Some people are asking about MATIC-MSAND LP staking with the same issue. Use the MATIC-MSAND contract instead, and use the "stake" button on "Write Contract" to add your LP amount, if you have LP tokens in your wallet. Remember to remove decimal points (.). That contract is found here: polygonscan.com/address/0x4ab071c42c28c4858c4bac171f06b13586b20f30

I did everything you said but once i click get reward all it does it transfer 0 msand even though i have more, the transaction goes through but it just wont send over any msand

[@thINKtattoos]

What happenned when we're not on the mSAND Polygonscan Staking Contract adress you told, but on a different adress, how can i fix that ?

[@CastleCrypto]

I don't think anything will happen if you are on the wrong address. You might waste some Matic on a transaction though.

[@amykan9623]

It works!!! Nice!! Thanks!

[@Jacob-uu8ql]

Do I have to wait for my staking rewards period to be over before I can withdraw my sandbox?

[@a.p8941]

It works!! thank you buddy!!! 🙌🙌

[@vofaofficial9785]

Please answer me if you see this. When I try to confirm transaction it says :"This connection is expected to fail There might be an error in the contract and this transaction may fail". I get that same message on both staking contracts (matic-msand and just msand). I made sure I have more than enough msand, matic and Im connected to the correct network, and made sure contracts are legit. It also says "Transaction decoding is not available for chain id 137"

Try fully resetting Metamask in Advanced Settings, and also clearing all browser cache and cookies.

[@timolehto7481]

what is the function for "approve"? Is there one? I try to go straight to the function "stake" and metamask is suggesting a exaggerated fee of 1matic, warning that it will likely fail, and it indeed does..

[@CastleCrypto]

I am actually not sure, from looking at the contract page I don't seem to see one unless it is worded a certain way.

[@sillysausage6052]

Hi Timo, to approve there's a few steps you need to do: - Go to SAND token page on polygonscan (0xBbba073C31bF03b8ACf7c28EF0738DeCF3695683) - Go to Contract > Write Contract > and scroll to number "2. approve" - Enter the mSAND Polygonscan Staking Contract address (0xA6E383bdA26E4c52A3A3a3463552c42494669aBd) & the amount you want to approve and write the transaction. You'll then be able to stake your mSAND on the staking contract. Hope this helps!

[@Kojanger]

I did exactly the same in the video. I pushed "claim" and "exit" button. And now all my msand tokens are gone. I check my Metamask wallet and Sandbox defi balance page and see nothing. Please help!

[@fauzybima2826]

Hey! I kept getting erro message which said "your allowance is still less than the amount you want to stake"" when trying to approve the staking using zenly wallet. Any helps about this?

[@Zenthara]

Needed this! Thanks!

[@hahabitok]

Hello! Same problem but when buying keys and receiving rewards. How to fix?

[@Musicmaniac-bg2zv]

I tried couple of times and now it's showing ur wallet is locked and transaction failed

[@Cars023]

Same here

[@growcrypto6103]

Does this work for when you claim sand after winning alpha pass?

[@andrasabraham6993]

It doesn't work for me either. Were you able to solve it?

[@CastleCrypto]

You need to be on Ethereum Network for claim SAND, it is not Polygon.

[@Stackoins]

Good info! Nice and thanks! +1

[@CastleCrypto]

You're welcome.

[@cryptonite9530]

This worked for the Sand only staking pool. How do we do the same thing for the msand-poly LP pool?

[@cryptonite9530]

Seeing your pinned comment just now lol

[@grantholman7034]

Thanks for sharing this :)

[@DannyTumia]

nice video, Im currently experiencing a different error. My staking isnt showing up at alll..... "error: returned error: exceeded project daily request limit"

[@littlepie1052]

I am getting the exact same message stated today *error returned error: exceeded daily request limit"

[@littlepie1052]

Did your information come back? Mine did after about 12 hours it came back by itself.

[@CastleCrypto]

This has to do with the monthly free gas transactions. They reset every month.

[@z3n308]

[@Rico_MC]
