Hello i have tecnical questions 😕 , i try to understand when i use this link : [TomoBridge](https://bridge.tomochain.com/wrap)

- I read the documentation with here : [TRC21 Wrapped Token - TomoChain Docs](https://docs.tomochain.com/tomobridge/faq/trc21-wrapped-token)

but i really still have questions …

- frist at all i really wanna test for my own but i dont have real tomochains o cryptocurrency to test it, and “bridge tomochain” i think dont has test mode

(wrap)

- i understand when i wrap “BTC” to “TRC21” this “BTC” changes to “TRC21 BTC” that is a token in tomochain,¿ i am right or i am wrong ?, in this point i think im right

(unwrap)

- the most important question for me is … when i do the reverse step example :
- “TRC21” to “BTC” , this “TRC21” that i transfer is trasnfer in the real “BTC” ?, ¿ like a exchange ? ,¿ channing “TRC21” to real “BTC Blockchain” ? or ¿ i still having “TRC21” into the tomochain ?

sorry for my bad english, i hope you can understand ❤
