Nevertheless, having secured $9 million in funding, the project has done quite a bit, released several applications, and the winning potential is decent.

Of course, it doesn't have the technology of Sonic, nor the popularity and background of Balance; diversifying investments is a good strategy.

Balance remains the most cost-effective node at the moment:

Sonic is also worth checking out; this technical architecture looks very good, compatible with Solana and EVM, and utilizes the Cosmos SDK for decentralization.
