Tokens with which a user is initiating the Porting Execution. The only exception to this is when a representative version of a token is being burnt on the portal to unlock a native network token.For example:A user sends HBARs from Hedera to Ethereum generating HBAR [eth]: HBARs are the Domestic Token & HBAR[eth] the Foreign Token.A user then sends HBAR[eth] from Ethereum to Polygon: HBAR[eth] are the Domestic Tokens and HBAR[0x] are the Foreign Tokens.A user then sends those HBAR[0x] back to Hedera: In this one specific instance, when porting back to the originating network, HBAR[0x] is a Domestic Token residing on the Polygon network but is also a Foreign Representative Token of the HBAR Native Token residing on Hedera.Native Tokens are ALWAYS Domestic Tokens.
