neo-utils

Useful functions for the NEO blockchain written in Go.

This library can be fully compiled to native iOS and Android framework using gomobile bind

note: gomobile does not support slice parameter yet so some functions are optimized to take a comma separated string as a param instead of a array of string.
For methods specifically designed to be used on mobile see mobile.go

The Unity project reported an error when introducing the compiled neoutils.framework.

There is no problem with neoutils.framework for use in OC and Swift projects. Introduced in the project written in unity language, the compilation is successful but the runtime reports an error. The error message is "runtime/cgo: could not obtain pthread_keys tried xxx". The content screenshot is as follows.

I have checked the related documentation but have not found a solution. Thank you very much for helping to solve this problem as soon as possible.

Getting error when install package.

Please take look at below screenshot

Getting unspent/UTXO in a decentralized way

Is there a way to get unspent/UTXO data without API calls? I don't want to depend on it. Or is there the API server code so that I could copy UTXO generation from there?

Could you possibly also link to NEO API docs regarding unspent? I couldn't find it anywhere...
