Both Sui and Aptos addresses start with “0x” and are 66 characters long, posing a risk of confusion.

ChainCatcher reiterated the need for increased awareness and caution in managing these blockchain addresses.

In response, security leaders like SlowMist’s “cosine” have urged users to double-check destination addresses before transacting. Community reactions call on wallet software developers to integrate warnings to avert such mishaps, advocating for improved user interface safeguards.

Yu Xian (Cosine), Co-founder, SlowMist, – “Users need to be aware that the private key corresponding to the Sui address cannot derive the same address on Aptos, and they cannot be converted to each other. For example, if you have Aptos and accidentally transfer to your Sui address, then the funds are lost…”
