The error means the contract needs to be recompiled.

I do think this error should be clearer. Perhaps it could check before deploying.

ok thanks ... but i have tried after cargo clean and then compiling again and also i am using a very simple smart contract of hallo world from documents . so what can be reaseon

[willemneal]

What is the version of the sdk? I should have been clearer. It means that it needs to be recompiled with an sdk that is compatible with futurenet.

Going to close this since it's been almost 2 months with no further discussion. Please try to recompile with an SDK that is compatible with futurenet and re-open if you're still experiencing an issue.
