Every XP gain, skin evolution, or weapon forge is a paid state transition. Players don't just win items; they buy the right to evolve them via micro-transactions that settle on-chain instantly, making every visual upgrade a proof-of-investment. Fees go directly to the game balance for real-time asset upkeep. Every unlock is a single 0.01 USDC payment behind an HTTP 402 gate — you pay for what you actually use.

Kernel
an HTTP 402 challenge in front of exactly one valuable operation — an export, a render, a full-resolution download — where each unlock is a single USDC payment bound to its settlement tx
Drives the UI as
a locked panel that states its price before you sign, plus an 'unlocks bought / used' counter beside the released payload
