1. What is Swap Protection?

Swap protection is a safety mechanism used when you exchange one token for another on a decentralized exchange (DEX). Its main purpose is to protect you from unexpected losses during the swap.

Key components

• Slippage Protection: Prevents your trade from executing if the price changes too much while the transaction is pending.
• Example: You expect 100 tokens, but if the price moves and you would only get 80, the transaction fails instead of executing at a loss.
• MEV / Front-running Protection: Helps prevent bots from manipulating the price before your transaction executes (commonly seen on Ethereum).
• Minimum Output Guarantee: You set a minimum amount you are willing to receive. If the actual output is lower, the transaction is cancelled.

In short: Swap protection helps protect against price changes, bot manipulation, and poor execution.

2. What is Network Cost in Blockchain?

Network cost (also called gas fee) is the fee you pay to process a transaction on a blockchain.

Whenever you:

• Send tokens
• Swap tokens
• Interact with smart contracts

You must pay a fee to the network.

Why does it exist?

• To reward validators/miners
• To prevent spam transactions
• To secure the network

Example (Ethereum)

• Every operation costs gas
• Gas price depends on network congestion

Key factors affecting cost

• Network congestion: More users usually means higher fees.
• Transaction complexity: Swaps generally cost more than simple transfers.
• Blockchain used: Ethereum usually has higher fees, while Polygon, Arbitrum, and Optimism are often lower.

In short: Network cost is the fee paid to execute your transaction on the blockchain.
