# Tornado Cash post-censorship
|
|
|
|
This is a guide to using Tornado Cash after the 8th August crisis, when the OFAC decided to sanction the organisation and the smart contracts. This led to a widespread wave of censorship from middleware service providers, resulting in users being vulnerable and unable to access their assets.

The latest community builds are available at:
|
|
|
|
- Classic:
|
|
- [tornado.ws](https://tornado.ws)
|
|
- [ipfs.io/ipns/tornadocash.eth](https://ipfs.io/ipns/tornadocash.eth/)
|

|
|
|
|
#### TOR network
|
|
|
|
**Browser history must be enabled when using TOR browser for event caching**.
|
|
|
|
How to use Tornado site via Tor: [guide](../tor.md).
|
|
|
|
#### IPFS details
|
|
|
|
To get the IPFS content hash and link from the domain details. Visit the ENS application domain page at either:
|
|
|
|
- Classic: [tornadocash.eth](https://app.ens.domains/name/tornadocash.eth/details)
|
|
- Nova: [nova.tornadocash.eth](https://app.ens.domains/name/nova.tornadocash.eth/details)
|
|
|
|
The IPFS link for Classic (tornadocash.eth) for example, will look like:
|
|
|
|
```
|
|
ipfs://bafybeiahmpy4e3p4ao2sqqxc2kb4htwl3oklsjncz2are6vnljecmdgmou
|
|
```
|
|
|
|
The content hash of this link is `bafybeiahmpy4e3p4ao2sqqxc2kb4htwl3oklsjncz2are6vnljecmdgmou`
|
|
|
|
#### Local IPFS deployment (recommended)
|
|
|
|
- Brave
|
|
|
|
- Navigate to the IPFS link in the browser
|
|
- When prompted, choose “Use a Brave local IPFS node”
|
|
|
|
- Chrome / Firefox
|
|
- Install IPFS Desktop
|
|
- Install IPFS Companion extension ([Chrome](https://chrome.google.com/webstore/detail/ipfs-companion/nibjojkomfdiaoajekhjakgkdhaomnch?hl=en) / [Firefox](https://addons.mozilla.org/en-US/firefox/addon/ipfs-companion/))
|
|
- Ensure IPFS Desktop is open and has an internet connection
|
|
- Navigate to the IPFS link in the browser
|
|
|
|
#### IPFS gateway usage
|
|
|
|
- Take the content hash and prefix it followed by a `.` to one of the following IPFS gateways:
|
|
- `ipfs.dweb.link`
|
|
- https://bafybeiahmpy4e3p4ao2sqqxc2kb4htwl3oklsjncz2are6vnljecmdgmou.ipfs.dweb.link
|
|
- `ipfs.cf-ipfs.com`
|
|
- https://bafybeiahmpy4e3p4ao2sqqxc2kb4htwl3oklsjncz2are6vnljecmdgmou.ipfs.cf-ipfs.com
|
|
- `ipfs.io`
|
|
- https://ipfs.io/ipfs/bafybeiahmpy4e3p4ao2sqqxc2kb4htwl3oklsjncz2are6vnljecmdgmou
|
|
|
|
#### Decentralized sources
|
|
|
|
All sources (code) of Tornado Cash are also decentralized after [proposal #30](https://tornado.ws/governance/30) and have ENS domains with IPFS contenthash.
|
|
Full guide available at ENS domain [sources.tornadocash.eth](https://app.ens.domains/sources.tornadocash.eth), actual IPFS hash: `bafybeia2s5em2xypmtdifuyj62xwgveujygs4vzoqhbqd2um45wbdxxb6u`.

### RPC

|
|
|
- If you want to deposit you may have to change your wallet RPC, as most providers have censored the smart contracts. **The default provider of Metamask, Infura along with Ankr and Alchemy currently do not prohibit transactions to and from the protocol, governance and the TORN token**.
|
|
|
|
- Try searching for an alternative working endpoint on [Chainlist](https://chainlist.org/), which could take multiple attempts (take note of the ChainID for network configuration). An example of how to change your RPC provider for MetaMask is shown below.

|
|
|
|
- Sometimes visiting the application you could be greeted with the following message, to fix this click "OPEN SETTINGS".
|
|

|
|
|
|
- You'll then be displayed a dropdown selection, defaulted to a selection. Click on it and select the "Custom" option.
|
|
|
|
![](../../../.gitbook/assets/zrY5GEi.png)
|
|
|
|
- Here enter a non-censoring RPC provider depending on your network and this will resolve application issues.
|
|
|
|

|
|
|
|
- Then you are freely able to withdraw, deposit, stake or participate in decentralized governance like nothing ever happened.

## FAQ
|
|
|
|
> Why do I keep recieving the error `Failed to fetch relayers`?
|
|
|
|
- This error is either related to a poor connection or a result of no available relayers on your network. It usually can be solved by refreshing.
|
|
|
|
> Why do I keep recieving the error `Failed to fetch proving keys`?
|
|
|
|
- This error is either related to a poor connection, it usually can be solved by refreshing or changing VPN location for better latency.
|
|
|
|
> Why do I keep recieving the error `Failed to fetch all deposit events from contract` when trying to withdraw?
|
|
|
|
- This error is related to a poor connection or using a censored RPC endpoint. To resolve this either:
|
|
- change VPN location for better latency
|
|
- try a new browser or method of access
|
|
- configure the application RPC configuration to an alternative
|
|
|
|
> Why can't I make a deposit from my wallet?
|
|
|
|
- Most RPCs censor transactions to the protocol and governance since the OFAC sanctions, you need to configure your wallet RPC to a uncensored endpoint. .
