What it is

Forgemint is a fully on-chain inscription protocol on Base. Each inscription is a tier-weighted ERC721 NFT minted through a linear bonding curve. After the mint phase completes, the protocol activates — pairing collected ETH with a newly-minted ERC20 (FORGE) into a Uniswap V3 LP. Inscription holders earn pro-rata pool rewards forever based on their inscription weight.

Three twists differentiate it from a vanilla inscription drop:

1. Tiered Rarity — Mint order determines tier:

   • #1–100 → MYTHIC (weight 10×)
   • #101–1000 → LEGENDARY (weight 3×)
   • #1001–21000 → COMMON (weight 1×)

2. Forge Mechanic — Burn 3 inscriptions of the same tier to mint 1 of the next tier with a +33% bonus on combined weight.

3. Fee Reroute — After activation, Uniswap V3 LP fees flow back to the rewards accumulator and are distributed pro-rata to inscription holders forever.

Bonding curve

price(n) = MIN_PRICE + (MAX_PRICE - MIN_PRICE) × n / MAX_SUPPLY
        = 0.0005 + 0.00475 × n / 21000  (ETH)

• Min price: 0.0005 Ξ (slot #1)
• Max price: 0.005 Ξ (slot #21,000)
• Max per tx: 50
• Max supply: 21,000
