Scall.io is a decentralized Perpetual Options protocol on the Base blockchain, enabling traders to open perpetual Call or Put options at a specific strike price. Positions remain open as long as traders continue paying the contract fee, which is charged per block.
On the other side, Liquidity Providers supply tokens that traders use to open positions. In return, traders compensate liquidity providers every second for accessing their funds. Liquidity providers receive an NFT representing their position, which can be transferred. The ERC721 holder has the right to withdraw the associated funds.

Scall.io is a decentralized perpetual options protocol on the Base blockchain. It allows traders to open perpetual call or put options at a specific strike price and remain open as long as they pay rent.
Unlike traditional options, which have an expiration date, Scall.io offers perpetual options that stay open indefinitely, as long as the trader pays the required rent. Traders can close or exercise their options at any time.
Yes, the protocol is fully decentralized and runs on smart contracts. It does not require intermediaries to execute trades or manage liquidity.
Traders must maintain at least one week's worth of rent as collateral. If the collateral balance drops below the required minimum, liquidation may occur, closing all open trades.
The rent is determined by the Liquidity Pool configuration and can be adjusted over time. Currently, it is set at 20% APR of the Open Interest and is charged in real-time, block by block.
Yes, you can withdraw your funds at any time as long as they are not actively being used by traders. If your liquidity is locked in open positions, you’ll need to wait until traders close their positions or additional liquidity is added by other LPs. Alternatively, you can sell your NFT position, which continues to earn fees, on the secondary market.

Options trading offers powerful tools for investors, and understanding the differences between European options, American options, and Perpetual options is essential for anyone navigating both traditional finance and DeFi platforms like Scall.io.
European options are financial derivatives that can only be exercised at the date of expiration. They are commonly used in institutional trading, especially with index options. Because they are less flexible, they typically come with lower premiums compared to American-style options.
American options can be exercised at any time up until expiration. This flexibility provides traders with more control, but it also makes these options more expensive. American options are popular in stock markets and are standard on many traditional exchanges.
Perpetual options are an innovation in decentralized finance. These options have no expiration date and stay open as long as the trader continues to pay a small recurring fee (e.g., rent per block). Platforms like Scall.io allow users to open perpetual call or put options with complete control over when to close their positions.
| Feature | European | American | Perpetual (Scall.io) |
|---|---|---|---|
| Exercise Date | Only at expiration | Any time before expiration | No expiration |
| Pricing Model | One-time premium | One-time premium | Continuous fee (per block) |
| Flexibility | Low | Medium | High |
| Tradability | Limited | Limited | ERC-721 NFT position (transferable) |
Perpetual options revolutionize how traders interact with options. Instead of being bound by expiration dates, users rent a strike price. This model enables more dynamic risk management and unique strategies. Scall.io is pioneering this movement with on-chain options, real-time pricing, and liquidity provider incentives through NFTs.
On Scall.io, liquidity providers supply tokens for options to be opened. In return, they earn continuous fees and receive an NFT representing their position. These NFTs are tradable and represent a share in the active liquidity pool.
"Perpetual options offer the flexibility of American-style options with the decentralization of DeFi — and without any expiration pressure."
Whether you're a trader looking for flexible risk management tools or a liquidity provider searching for yield opportunities, Scall.io offers a modern solution to the limitations of traditional derivatives.
Liquidity Providers (LPs) on Scall.io can earn a base yield of 20% APR by locking assets at specific strike prices. But for more experienced users, there are strategies to amplify returns or better manage risk. Here are two smart strategies designed for a BTC/USDC market where BTC currently trades at $80,000.
Goal: Create a delta-neutral position that earns a high, stable yield.
How it works:
Result:
When BTC hits $81,000: Your liquidity might be exercised. Close the short position to settle and realize total yield.
Benefits:
Risks:
Goal: Maintain long exposure to Bitcoin, earn passive income on both BTC and USDC, and minimize slippage.
How it works:
When BTC hits $81,000: Your BTC may be exercised, converting it into USDC. Then, use the $81,000 USDC to buy a new short-term Call option at the same strike.
This allows you to:
Benefits:
Risks:
Hedged Short + LP: Delta-neutral, 20% + 15% APR, medium risk, requires monitoring.
Exposed LP with Re-entry: Long BTC, 20% + 5% APR, low risk, ideal for passive investors.
These strategies highlight how Scall.io empowers LPs not only to provide liquidity but also to optimize returns with strategic positioning. Whether you're risk-averse or yield-hungry, Scall.io has flexible tools for your needs.
Scall.io opens the door to powerful trading opportunities by allowing traders to use perpetual options to profit from price swings and volatility. Whether you're bullish, bearish, or neutral, there’s a strategy designed for you.
Goal: Accumulate exposure at the lowest possible entry point during a downtrend.
How it works:
Why it works: You're always positioned at the bottom, and rent becomes cheaper as Open Interest drops with each dip.
Best for: Long-term bullish traders aiming to catch the bottom without needing to time the market perfectly.
Goal: Secure high exit points in anticipation of a correction.
How it works:
Why it works: You build a ladder of profitable exit points, ensuring you're protected when the price reverses.
Best for: Cautious or bearish traders preparing for a potential market downturn.
Goal: Profit from significant price movements, regardless of direction.
How it works:
Why it works: This strategy (a long straddle) thrives on volatility — you don’t need to pick a direction, just expect movement.
Best for: Traders expecting volatility or reacting to upcoming news events.
Buy the Dip: Bullish | Perpetual Calls | Accumulate at lower prices
Sell the Top: Bearish | Perpetual Puts | Lock in high exit points
Capture Volatility: Neutral/Volatile | Calls + Puts | Profit from large moves
These strategies show how perpetual options on Scall.io aren't just about taking positions — they're about adapting to any market and gaining a trading edge, no matter where the price moves.
