How to Bridge Your $DBIO and $USDT to the DeBio Network Appchain

$DBIO is a native token on the NEAR Protocol but compatible with a Substrate-based chain thanks to the Octopus Network bridge. This also applicable for $USDT.e (a token representing USDT on NEAR Protocol that was bridged from the Ethereum blockchain via the Rainbow Bridge). inside The Octopus Network bridge transfers value from a native NEAR Protocol token into their Appchains. Every Octopus Network Appchain is a Substrate-based chain because Octopus Network is built on top of Substrate for interoperability purposes.
