Technical questions regarding ATOM and addresses

Hi,

are there any technical documents available in regards to these questions?
– how many decimal places has the ATOM token?
– are there ATOM subunits like Satoshi for BTC?
– is there a fixed length for addresses?
– is there some kind of checksum / address validation method?

Thanks for any help!

– how many decimal places has the ATOM token?
6

– are there ATOM subunits like Satoshi for BTC?
0.000001 ATOM is 1 uATOM

– is there a fixed length for addresses?
Yep, just go through your set of Keplr addresses for example

– is there some kind of checksum / address validation method?
Bech32 is used, there are some converters out there (don’t have the links available though)

Thanks LeonoorsCryptoman!
