brz-token-bridge

The token bridge provides the logic for transfer BRZ token between blockchains.

Tech process:

• An account call the function receiveTokens in blockchain A sending tokens.
• An external monitor follow the event CrossRequest.
• Wait N confirmations of a receiveTokens's transaction.
• The external monitor calls the function acceptTransfer to send tokens to the destination's account.
