In the first bridge i follow a tutorial and can sen Syscoin to metamask for trading on pegasys, all well. But i try to give back the syscoin to poli wallet for trade in other exchange and mek the NEVM to SYSX bridge. The 1 and 2 steps was correct but somethins was wrong on 3 becouse the money never arrived to poli wallet.
