Chain fees (SOL & EVM)

When you trade through OPSIN, your transaction interacts directly with the blockchain — and like all on-chain activity, that comes with a few types of fees. Here’s a breakdown of what to expect, how it works behind the scenes, and how to optimize the settings to execute faster.

Network Fee

This is the standard fee you pay to get your transaction included in a block.

• On Solana: It’s usually minimal (few cents)

• On EVM chains (Ethereum, BNB, Base, Arbitrum): It varies based on network congestion (known as gas).

OPSIN automatically sets an optimized base fee so your trade is confirmed efficiently.
