Why Sonic $S prev. $FTM ?
1. Faster than any of the ones you mentioned + sub second true finality (not probabilistic). Comparitively its asking "why fibre when adsl is already fast enough"
2. Fee monetization, 90% of fees go to dapps not validators, creating revenue streams for builders (same reason many big dapps are launching L2s, but with us they dont sacrifice composability)
3. Fee subsidies, can onboard users without them needing fees.
4. Native account abstraction, no onboarding wallet friction.
Sonic, while a nextgen technical solution, is focused heavily on the dapp builder and end user journey and focused on creating a better and more sustainable environment for them.
