Just a story from a beginner. I have been playing for a week and do a bit of trading for the last few days. Today, i got an error message below when using Splinterlands and i can no longer trade. Looking at Splinterlands FAQ, this has not been mentioned to new player. Before sending a ticket for help, i did a bit of googling and found these two useful article below. Just wish i read these articles sooner and understand a bit more how hive keychain work. All i can do now is wait for my RC go to up and allow me to trade some DEC to Hive and power up my Resource Credit.
