# Tornado Pool [](https://github.com/tornadocash/tornado-pool/actions)
|
|
|
|
This an experimental version of tornado.cash that allows to deposit **arbitrary amounts** and make **internal(shielded) transfers**.
|
|
|
|
Other facts about this version:
|
|
|
|
1. It uses L2 (xdai). Xdai has a ETH(mainnet)<>WETH(xdai) bridge that will be used under hood.
|
|
2. Contracts will be upgradable by tornado-cash governance! xdai bridge supports transferring messages from L1 to L2 and vise versa, so community can always upgrade tornado-pool to a new version in case of an issue.
|
|
3. Since it's a beta version, deposits are limited by 1ETH. Governance can always increase the limit.
|
|
4. Withdrawal amount from pool to L1 has to be larger than 0.05 ETH to prevent spam attack on the bridge.
|
|
5. The code was [audited](./resources/Zeropool-Tornado.pool-audit.pdf) by Igor Gulamov from Zeropool.
