 # Tornado Pool [![Build Status](https://github.com/tornadocash/tornado-pool/workflows/build/badge.svg)](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.

-## Useful
-
-How we do transaction inside pool of A amount.
-
-1. sort inputs by amount
-2. try to take 1 or 2 smallest inputs to satisfy A amount. Get 16 inputs if it's not possible using the same way
-3. Also you can always use transaction to merge your inputs with change (especially in 16 inputs case)
