Smart contract source code

let hashBytes = base58'59aguGcT6YgwAx22S4jLnW7GWCqdfhxTjNFUCA9S5ncr'
match tx {
  case win:MassTransferTransaction =>
    let hint = "Feel free to check the Waves Wall project"
    sha256(win.attachment) == hashBytes
    && win.transfers[0].recipient == addressFromString("3PPPPPpPDKZYvBHmSB71PTwnepyWHMrNgfY")
    && win.transfers[0].amount >= win.transfers[1].amount / 10
  case _ => false
}
