Cellframe Bridge is a service which provides token exchange among our networks and between ours and other networks. 1. Between our networks CF20 KEL <-> BB There is a transaction created in one network to the address of another network. Bridge-node which is actually working in both networks sees these transactions and releases emission in the destination network. 2. Between external networks ERC20 <-> BEP20 Is implemented by smart contracts. 3. And from external networks to ours ERC20 -> CF20 | BEP20 -> CF20 It now works only in one direction. Coins in ethereum are blocked on smart contract, bridge-node sees this and releases emission in our network. Official Cellframe Bridge site - https://bridge.cellframe.net/ Service UID - 0x04
