Key Terms in the GumBall Protocol Ecosystem
gNFT - an NFT minted on GumBall Protocol
GBT- GumBall Token, ERC20 token specific to a collection. 1 of 2 token reserves in collection's bonding curve.
  • rGBT = reserve GBT, equal to aGBT
  • aGBT = actual GBT available for trading in the bonding curve
  • cGBT = circulating GBT, GBT held outside the bonding curve
  • tsGBT = total supply GBT, equal to rGBT + cGBT
  • buGBT = burned amount of GBT, destroyed when gNFT is converted to GBT
  • rbuGBT = burned amount of rGBT, destroyed in correlation to buGBT
Base Asset (ex ETH) - second token reserve in a collections bonding curve, allows for instant liquidity
  • vETH = virtual ETH, placeholder ETH used to set bonding curve floor price
  • aETH = actual ETH , real ETH in the bonding curve avaialble for trading
  • bETH = borrowed ETH, a placeholder to track the amount of ETH outside the bonding curve
  • rETH = reserve ETH, equal to (vETH + aETH + bETH)
  • ETHin = ETH sent to contract
  • ETHout = ETH received from contract
GumBall Factory = The GumBall Factory contract is where collections are created
ERC20 Bonding Curve = The bonding curve is a mechanism for distributing GBT while maintaining guaranteed liquidity for circulating GBT. GBT is bought and sold from/to the bonding curve.
GumBar = The GumBar contract is the staking contract. Users may deposit to stake GBT or gNFT, which earns yield in the form of GBT and the Base Token (ETH).
GumBall Machine = The GumBall Machine contract converts GBT<->gNFTs. This is the mechanism granting every NFT in the GumBall ecosystem guaranteed liquidity.
