Where can I check EOS tokens(EOSDT, Everipedia, Newdex, etc) precision points?
If the token is based off the eosio.token contract, you could get the stat table and see what the precision is there. For example, for EOS
$ cleos get table eosio.token EOS stat
{
"rows": [{
"supply": "1024177197.2358 EOS",
"max_supply": "10000000000.0000 EOS",
"issuer": "eosio"
}
],
"more": false
}
For EOSDT
$ cleos get table eosdtsttoken EOSDT stat
{
"rows": [{
"supply": "5562623.798696016 EOSDT",
"max_supply": "70000000.000000000 EOSDT",
"issuer": "eosdtcntract"
}
],
"more": false
}
