When using blockchain-based features like swaps, liquidity tracking, and smart contract interactions, errors may occur due to various factors. Here's a detailed breakdown of the most common errors, their causes, and how to resolve them.

1. Slippage Control

Error

“Failed due to ‘executing swap was failed on the blockchain. Reason: Exceeds desired slippage limit’”
