💡
Tron and Solana networks have the lowest gas fees and fastest confirmation times. If you have a choice, prefer TRC-20 or SPL for small top-ups.
Which network should I use?
| Network | Gas fee | Speed | Best for |
|---|---|---|---|
| Ethereum (ERC-20) | Higher | ~2 min | Large top-ups ($100+) |
| Tron (TRC-20) | ~$1 | ~3 sec | All sizes — best value |
| Solana (SPL) | <$0.01 | ~1 sec | All sizes — fastest |
