# 5.5.5. Blockchain Preference

Each smart contract-based savings group will operate on a blockchain network selected by Nexspecto. 

The specific asset and size of the relevant group will be important in choosing the blockchain network of savings groups offered by Nexspecto. 

In large-pool savings groups where the gas fee is insignificant, networks with a high gas fee such as Ethereum will be preferred for reasons such as security, ecosystem and liquidity, while networks such as Polygon with a low gas fee will be preferred in small-pool savings groups where the gas fee is important. 

Ethereum and Polygon networks will be integrated into the Nexspecto platform first. In line with the vision of the Nexspecto platform to be multi-chain. Furthermore, there will be more network integrations and Nexspecto will reach wider Web3 communities, while platform users will have access to Web3 assets and applications at a wider scale. 

For more detailed information on the blockchain infrastructure of Nexspecto savings groups and assets, you can review the "Nexpecto's Blockchain Infrastructure" section.
