The Starknet ecosystem is really basic and doesn't have many special features but
Starknet Foundation is trying to build a generation of DeFi 2.0 projects with some names like Vesu, Nimbora,... and betting more on FOCG.
StarkWare is constantly rolling out upgrades to make the Starknet network faster & cheaper. Upgrades are happening on a monthly basis.
Along with that are improvements that make it easier for developers to work on Starknet.
$STRK is one of the tokens with the most Use Cases in the old quartet including governance, payment and soon Staking.
Starknet also has many Grants & Mini Hackathons to attract developers to its ecosystem. But if we talk about whether these events are grand and effective or not, it is only average.
Starknet is creating a new trend for itself by possibly being one of the first Layer 2s to work on both Bitcoin & Ethereum with Rollup technology.
Most Layer 2s suffer from similar to Starknet in terms of tokenomics.
P/s: One similarity between Starknet, Sui & Sei is the letter S at the beginning. I will still bet on the Starknet ecosystem for a long time to come!
