▮ SCALE

Leverage trade any Noxa memecoin up to 10x — on Robinhood Chain

Every position is a real Uniswap V3 buy — not a perp, not paper. Your long moves the actual chart.

What is SCALE?

SCALE is on-chain leverage for memecoins launched on Noxa, running on Robinhood Chain (an Arbitrum Orbit L2, chain id 4663). A trader posts ETH collateral, the protocol's capital pool fronts the rest, and the full leveraged size market-buys the token on Uniswap V3 — immediately, on-chain. Close in profit and the tokens sell back; close in loss and the pool recovers its capital first. The pool never loses, so it can keep fronting size indefinitely.

• Up to 10x on any listed Noxa token — real spot buys, no order book, no counterparty
• 1-second charts decoded live from Uniswap V3 Swap events, straight off the chain
• Server-side TP / SL enforced every 10 seconds by a background monitor
• Custodial wallets — email/password or Google sign-in, no browser extension
• Trustless listings — fee redirects verified against Noxa's own FeeRouter contract
• Max loss is always your collateral — the pool exits before its capital is at risk

How it works

Trader posts 0.1 ETH collateral, picks 5x
  → 0.1 ETH moves to the protocol pool
  → pool adds 0.4 ETH
  → 0.5 ETH exactInputSingle on Uniswap V3 (SwapRouter02)
  → real tokens held; position monitored every 10s, 24h max
  → auto-closes on TP / SL / liquidation threshold / timeout, or on user exit

Fee split (flat fee on position size): 50% deepens the pool · 30% to the token creator · 20% market-buys $SCALE and sends it to 0x…dEaD.

Profit split on a winning close: 70% cash to the trader · 30% auto-buys $SCALE, locked 7 days.

Token tiers

Tier	Max leverage	Liquidation	Basis
Bonded	10x	−15%	Deepest Uniswap V3 liquidity
Rising	5x	−12%	$100K+ market cap
Degen	3x	−10%	Live Noxa pool, thin liquidity

Safety model

• The pool recovers its capital first on every close — it cannot go negative
• Liquidation threshold shown before entry, enforced by the price monitor
• Insurance fund absorbs extreme-slippage edge cases
• 24h max duration — every position auto-closes
• On-chain verifiable — pool wallet, swaps, burns, and listing checks are all public
