"There have been some questions about Mercury in Slack and on Bitcointalk, so I wanted to lay out some points of emphasis on the subject. Mercury enables Sigwo Technologies to transact on Waves’ public blockchain without ever using a Waves coin. The first use case for Mercury is copying Jupiter’s block ID to Waves. With this test case and subsequent acceptance of Mercury by the Waves’ ecosystem, we now have a fully functional token that can be used to issue tokens, have our own Lite Wallet, and possibly have a Mercury-denominated DEX. The possibilities are limited to your imagination. I am very excited to see Mercury and the ideas that can come to fruition on this platform."
