Package gns implements the GNS governance and utility token for GnoSwap. GNS is a GRC20-compliant token with a deflationary emission schedule. The emission follows a 12-year schedule with halving every 2 years: - Years 1-2: 225,000,000 GNS per year (100%) - Years 3-4: 112,500,000 GNS per year (50%) - Years 5-6: 56,250,000 GNS per year (25%) - Years 7-8: 28,125,000 GNS per year (12.5%) - Years 9-12: 14,062,500 GNS per year (6.25%) Token Economics: - Maximum Supply: 1,000,000,000 GNS - Initial Mint: 100,000,000 GNS - Total Emission: 900,000,000 GNS Key Functions: - InitEmissionState: Initializes emission schedule (emission contract only) - MintGns: Mints tokens per emission schedule (emission contract only) - Burn: Burns tokens from circulation (admin only) - Transfer/TransferFrom/Approve: Standard GRC20 operations The emission state tracks accumulated and remaining amounts per halving year, ensuring precise token distribution according to the schedule.
Allowance returns the amount of GNS that a spender is allowed to transfer from an owner.
