Sierra SWAP was scheduled to June 04, 2020 (first SWAP announce was in February 2020, and web-wallet Sierra has opened for deposits) https://sierracoin.org/sierraswap/

Right now Sierra SWAP already finished successfully, and all participants have got new Sierra 3.0 coins + 10% EXTRA bonus from Sierracoin Team.

Sierra 2.0 network is no longer supported, and we recommend all services to update their Sierra wallets from v2 to v3 network to obtain correct data from current Sierra 3.0 network.
