G Token

This is the official repository for G Token.

The G Token is a new token contract replacing the old token GAL, proposed in GP25.

There are 3 contracts in this repository:

• GravityTokenG.sol: The main new ERC20 token contract, the G token. This token contract natively supports minter management for making G a native cross-chain token. Each minter will have limited minting power within a time window. Minters are enumerable. Implementation of this management is in LimitedMinterManager.sol.
• TokenUpgrader.sol: A contract to upgrade the GAL token to the G token.
• TokenVesting.sol: A simple token vesting contract.

Deployment

The contracts have been deployed at the following addresses:

G Token

Token Name: Gravity

Token Symbol: G

Initial Total Supply: 12,000,000,000 G

Contract Address: 0x9C7BEBa8F6eF6643aBd725e45a4E8387eF260649

Networks:

• Ethereum
  • Owner: Safe multi-sig on Ethereum
  • Initial supply: 10,000,000,000 G
• BNB Chain
  • Owner: Safe multi-sig on BNB Chain
  • Initial supply: 2,000,000,000 G
• Base
  • Owner: Safe multi-sig on Base
  • Initial supply: 0 G
  • Note: G tokens will be bridged from other networks to Base network.

G tokens can be natively bridged to deployed network via our official bridge, using cross-chain message protocols.

Token Upgrader

Only available on networks where the old GAL token is deployed:

• Ethereum
  • Ethereum Address: 0x249aC00402716b7bf6d6ED24531d7B4C10788942
  • Owner: Safe multi-sig on Ethereum
• BNB Chain
  • Owner: Safe multi-sig on BNB Chain
  • BSC address: 0x35272c5e7236d1042Af432046706111e314d1577
  • Note: This upgrader is different from Ethereum's upgrader that burns GAL tokens by sending them to 0xdead address. Instead, it will send the BEP-20 GAL token to the owner of the upgrader contract. The owner will then send those BEP-20 GAL tokens to the exchange that issued them, to burn and unlocked the original ERC-20 GAL tokens. Those ERC-20 GAL tokens will then be burned by sending to the 0xdead address on Ethereum.

G Token OFT

For chains that do not have G token contract deployed natively, we use Layerzero's OFT standard to bring G token to those chains.

• Token Name: GravityTokenG (OFT)
• Token Symbol: G.oft

Deployed networks:

• Polygon
  • Owner: Safe multi-sig on Polygon
  • Initial supply: 0 G (minted on demand by bridging from Ethereum mainnet)
• More to come...

Security configurations:

• OFT Adapter on Ethereum mainnet: 0x71c066fd4949C44B2cB2f509E2CD2421FbD36bca
