GEN Bridge is to serve as a connecting bridge that allows projects active in blockchain networks other than the Ethereum network to settle into the Pinetree Space platform more quickly and reliably. The Bridge is validated for security by GEN Protocol's Gate Keeper and settled in Pinetree Space, and the ecosystem can then be expanded by utilizing the platform's low network fees. Through this, projects operating in multiple blockchain networks can use Pinetree Space to reduce costs and receive infrastructure services that can expand the ecosystem even if a separate platform does not exist.



  1. 1.
    Pinetree Space Bridge uses GEN Bridge. GEN Bridge allows to send Ethereum mainnet based coins to GEN Protocol.
  2. 2.
    When a user sends an Ethereum mainnet GEN token (0xBBB) to the Bridge contract, the amount is locked in the MAINNET Bridge contract (0xAAA).
  3. 3.
    The locked quantity is propagated to the EVM logging event, and the Gate Keeper who confirms this signs the quantity and broadcasts it to the GEN Protocol, and when 2/3 of the lock is verified, the Bridge sends gGEN (0xDDD) is transmitted.
const MAINNET = {
bridge: "0xAAA",
peg: "0xBBB"
const GEN_PROTOCOL = {
bridge: "0xCCC",
peg: "0xDDD"
