What is SCALE?

SCALE is on-chain leverage for memecoins launched on pump.fun, running on Solana mainnet. A trader posts SOL collateral, the protocol's capital pool fronts the rest, and the full leveraged size market-buys the token via Jupiter — immediately, on-chain, whether the coin is still on its bonding curve or already graduated. 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 pump.fun coin — real spot buys, no order book, no counterparty
• Live 1-second charts streamed from Jupiter's price feed
• 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 — pump.fun launches verified against Jupiter's launchpad attribution; trending coins auto-list
• Max loss is always your collateral — the pool exits before its capital is at risk

How it works

Trader posts 1 SOL collateral, picks 5x
  → 1 SOL moves to the protocol pool
  → pool adds 4 SOL
  → 5 SOL market-buys the coin via Jupiter
  → 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 coin's creator · 20% market-buys $SCALE and burns it.

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

Getting started

git clone https://github.com/ScaleDotFun/scale.git
cd scale

pnpm install
cp .env.example .env        # fill in your values

pnpm --filter @scale/web dev

Open the URL Vite prints (defaults to http://localhost:5173).

Key environment variables

Variable	Description
SOLANA_RPC_URL	Solana RPC (defaults to the public mainnet RPC — use a dedicated one in production)
PROTOCOL_WALLET_PRIVATE_KEY	Base58 secret key (or solana-keygen JSON) for the protocol pool wallet
SCALE_TOKEN_MINT	$SCALE SPL mint (locked-supply stats + buyback/burn)
JUPITER_API_URL / JUPITER_API_KEY	Optional — paid Jupiter tier (defaults to the free lite tier)
COINGECKO_API_KEY	Optional — routes GeckoTerminal data through CoinGecko Pro
DATABASE_URL / REDIS_URL	PostgreSQL + Redis connection strings
ENCRYPTION_KEY	32-byte hex — encrypts custodial wallet keys at rest

See .env.example for the full list.

Token tiers

Tier	Max leverage	Liquidation	Basis
Bonded	10x	−15%	Graduated on pump.fun, deepest liquidity
Rising	5x	−12%	$100K+ market cap
Degen	3x	−10%	Live bonding curve, 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 listings are all public on Solscan
