isometric is a prediction market protocol on Solana that lets users bet on where a price will land rather than just whether an event will happen. Where Polymarket and most prediction markets use binary yes-or-no outcomes, Isometric replaces that with a continuous range. Instead of betting “will BTC be above $100k on April 30,” users pick a band like “BTC between $80k and $95k on April 30.”
Payouts follow a Gaussian distribution: hit the center of your range for the maximum payout, land close-but-not-perfect for a partial payout, miss entirely and you lose your collateral. Pricing uses an LMSR (Logarithmic Market Scoring Rule) model, and every position is minted as an NFT directly into your wallet, keeping custody with the user rather than a centralized counterparty.
Isometric is currently live on Solana devnet, so traders can test the full mechanic without putting any real capital on the line. The $ISO token is confirmed in the project’s whitepaper, which makes early devnet activity a plausible signal for a future retroactive reward.
isometric has not announced an airdrop, but the $ISO token is confirmed in the whitepaper and devnet activity is currently the only on-chain way to interact with the protocol. Protocols frequently reward early testers once mainnet launches, so Isometric sits in the speculative farming bucket.
Key Parameters:
Devnet users get free test USDC from the app and can trade across multiple prediction markets, close positions early, or hold to settlement. Liquidity providers can also deposit test USDC into the shared vault to simulate fee collection. Mainnet will follow protocol testing and security audits, with no firm date.
Install Phantom or another Solana-compatible wallet if you don’t already have one. Create a new wallet and save your seed phrase somewhere safe.
Open Phantom’s settings, go to Developer Settings, enable Testnet Mode, and select Devnet from the network dropdown. Other Solana wallets follow a similar path under network or developer settings.
Every Solana transaction needs a small amount of SOL to cover fees. On devnet, SOL has no real value. Visit this faucet to request SOL to your address.
Head to the Isometric app, click “Select Wallet” in the top right, and approve the connection in Phantom. Once connected, claim test USDC from the app to fund your trades.
Open the Markets tab and pick a market you have a view on, such as BTC or SOL price on a future date. Set a low and high bound using the sliders or one of the preset width buttons (Tight ±2%, Medium ±5%, and so on). Review the cost, click “Place Position,” and approve the wallet prompt. Your position will mint as an NFT held in your wallet.
Track open positions under the Portfolio tab. You can close early for a partial refund based on the current LMSR buyback price, or hold until the market settles and claim your payout against the final price.
LPs deposit test USDC into the shared vault that pays out winners and collects trading fees. To deposit, go to the Liquidity tab, click the “+” button, pick a pool, enter your amount, and confirm the transaction. Withdraw any time from the same tab to retrieve your USDC plus any earned fees.
