Strengths
- Dedicated node option for teams that need predictable performance.
- Wide non EVM coverage (Bitcoin, Solana, TRON) alongside EVM chains.
Considerations
- Free tier daily cap is global, not per chain — easy to exhaust on multi chain reads.
- Some chains are shared only; check whether dedicated is available before depending on it.
