As part of our efforts to support marketplaces that are offering multisig transactions, like we did before with TMP, Blackbank market & Drugslist (before the other issues) we are happy to post about this new market offering multisig transactions, and by this lowering the risk for both users and vendors, this is the instructions for using their multisig transaction system as it appears on their site, with the images included.

  • Customer deposits coins into HYDRA account, if vendor also set up their pubkey and address, customer can make purchase with multisig escrow.
  • Don’t need to enter your pubkey/address on every purchase (You can use it like PGP).
  • Hydra automatically will generate our own public key, charge fee, create a multisig address and send fund to this address
  • You can track multisig transactions on
  • 2 of 3 Private keys required to access the funds (e.g. Customer + Hydra -> refund, Vendor + Hydra -> finalize, Vendor + Customer -> finalize/refund/etc).
