## Option Writer Obligations

An option writer, also known as the seller, assumes a binding contractual duty to fulfill the terms of an option contract if the buyer chooses to exercise their right. When selling a call option, the writer is obligated to sell the underlying asset at the specified strike price if assigned.

When selling a put option, the writer is obligated to purchase the underlying asset at the strike price if assigned. This obligation remains active until the option expires or the writer performs a closing transaction to offset their position.

Because the writer takes on the risk of adverse price movements, they receive a premium from the buyer as compensation. In the context of cryptocurrency, this often involves collateral held in smart contracts to ensure performance.

If the market moves significantly against the writer, they may face liquidation if their collateral falls below maintenance requirements. This mechanism is central to the protocol physics of decentralized options exchanges.

The writer essentially acts as the liquidity provider, assuming the counterparty risk inherent in the trade. Managing these obligations requires careful monitoring of delta and gamma exposure.

Failure to maintain adequate collateral leads to automated liquidation protocols, illustrating the intersection of smart contract security and financial risk management.
