Recently I tried to transfer SEI coins from binance exchange to my compass wallet, I totally surprised with the speed of transection it take less than 5 seconds to receive SEI in my wallet after sending from binance exchange
SEI is a L1 blockchain and they calim it's a number one fastest blockchain ever build in cryptocurrency space, there is no doubt it's transection speed is very fast with around $0.05 cent per transaction fee which is also a reasonable fee
I tried many other blockchains for this like Solana, Polygon MATIC, Digibyte and Litecoin and I think SEI have better transection confirmation time and speed as compared to all of above as per my knowledge
But we have to remember it's still developing no nobody knows it's become so successful or not, may be it's have some other disadvantages along with good speed so do some research on it before investing or Bulding on SEI blockchain, may it's failed to compete with other top L1 blockchain like Solana, ethereum etc or may be become more successful then other top L1 blockchains
