 # Pretix Ethereum Payment Provider
 
-## **Warning**
-
-**!! This plugin is not ready for 3rd party production use *yet*.  If you want
-to use it you must really understand the code !!  PRs to make it production
-ready and more eyes on this code are most welcome!**
+**[Demo](https://www.loom.com/share/8c71876a9d5348f6a07a8d7e687368b6?sid=5b19c2a2-7502-4cf2-9afe-a865fd04e003)**
 
 ## What is this
 
-This is a plugin for [pretix](https://github.com/pretix/pretix). This plugin
-supports both Ethereum and DAI.
+This is a payment plugin for [Pretix](https://github.com/pretix/pretix) to accept crypto payments from any chain and any coin.
+
+Key features:
+- Accept payments in all liquid tokens on major chains, using Daimo Pay.
+- Clean 1:1 pricing for stablecoin payments. If a ticket costs $100, user transfers exactly 100.00 USDC, USDT, or DAI on any efficient chain.
+- Support for all major EVM rollups + Polygon.
+- Automatic bridging and forwarding to a single destination address.
+- Built-in refund support, using Peanut Protocol.
+
+## Event Setup Instructions
+
+1. Under the event, go to Settings > Plugins > Payment Providers, enable provider.
+
+2. Under Settings > Payments, enable payment method.
+
+3. Configure the following required settings:
+   - `DAIMO_PAY_API_KEY` - API key from pay.daimo.com
+   - `DAIMO_PAY_RECIPIENT_ADDRESS` - Address to receive payments (in DAI on Optimism)
+   - `DAIMO_PAY_REFUND_EOA_PRIVATE_KEY` - Private key for automated refunds (must be funded with ETH and DAI on Optimism)
+
+## Development Setup
+
+You'll need Python 3.10 and Node >20.
+
+1. Clone this repository
+2. Create and activate a virtual environment
+3. Run `pip install -e .[dev]` 
+4. Setup database: `make devmigrate`
+5. Start dev server: `make devserver`
+6. Build Daimo Pay checkout: `cd pretix_eth/static/daimo_pay_inject && npm i && npm run build`
+
+You can also use `npm run dev` on that last step to run a watcher.
+
+Finally, go to `http://localhost:8000`. Use `admin@localhost`, password `admin`. Create an org, an event, and follow the event setup instructions above.
+
+You should now have a working development Pretix instance.

 For DEVcon6 the plugin was extended with some more features like [Layer2 support by Rahul](https://github.com/rahul-kothari). Layer2 will play a significant [role in Ethereum](https://ethereum-magicians.org/t/a-rollup-centric-ethereum-roadmap/4698). Unfortunately DEVcon6 was delayed due to covid - but we where able to use and this way test via the [LisCon](https://liscon.org) ticket sale. As far as we know this was the first event ever offering a Layer2 payment option.
 In the process tooling like [Web3Modal](https://github.com/Web3Modal/web3modal/) / [Checkout](https://github.com/Web3Modal/web3modal-checkout) that we depend on was improved.
 
-### Recently added features
-
-* L2s added! 
-* A panel was added in the web admin interface to upload a list of addresses to
-  be associated with each ticket order.
-* During the checkout process, an address is chosen for each order from the
-  list of remaining addresses created by the address upload process.
-* A payment confirmation management command was added that confirms pending
-  payments based on the address assigned to them during checkout.  See the
-  `confirm_payments` section below for details.
-
-## Development setup
-
-1. Clone this repository, e.g. to `local/pretix-eth-payment-plugin`.
-1. Create and activate a virtual environment.
-1. Execute `pip install -e .[dev]` within the `pretix-eth-payment-plugin` repo
-   directory.
-1. Setup a local database by running `make devmigrate`.
-1. Fire up a local dev server by running `make devserver`.
-1. Visit http://localhost:8000/control/login in a browser windows and enter
-   username `admin@localhost` and password `admin` to log in.
-1. Enter "Admin mode" by clicking the "Admin mode" text in the upper-right
-   corner of the admin interface to create a test organization and event.
-1. Follow instructions in [Event Setup Instructions](#event-setup-instructions)
+For Devconnect IST an effort was made to improve the plugin in a variety of ways: WalletConnect support, single receiver mode (accept payments using just one wallet), more networks, automatic ETH rate fetching, improved UI and messaging, and smart contract wallet support. All of these features made it into this version of the plugin, except for smart contract wallet support - issues processing transactions stemming from sc wallets meant that we ultimately had to turn away sc wallet payments altogether.
 
-## Event Setup Instructions
-1. Under the event, go to Settings -> Plugins -> Payment Providers -> click on Enable under "Pretix Ethereum Payment Provider" 
-2. Next, under Settings, go to Payments -> "ETH or DAI" -> Settings -> click on "enable payment method". 
-3. Next, scroll down and set the values for the following:
-  - "TOKEN_RATE" - This is a JSON e.g. 
-    ```
-    {"ETH_RATE": 4000, "DAI_RATE": 1}
-    ```
-    i.e. `KEY` = `<CRYPTO_SMBOL>_RATE` and `VALUE` = value of 1 unit in your fiat currency e.g. USD, EUR etc. For USD, above example says 1 ETH = 4000$. If EUR was chosen, then this says 1 ETH = 4000EUR.
-  - Select the networks you want under the "Networks" option - Choose from Ethereum Mainnet, Optimism, Arbitrum and their testnets.
-  - "NETWORK_RPC_URLS" - This is a JSON e.g.
-    ```
-    {
-      "L1_RPC_URL": "https://mainnet.infura.io/v3/somekeyhere",
-      "Rinkeby_RPC_URL": "...",
-      "RinkebyArbitrum_RPC_URL": "..."  
-    }
-    ```
-    i.e. `KEY` = `<Network ID>_RPC_URL` and `VALUE` = RPC URL. Network IDs can be found [in tokens.py](pretix_eth/network/tokens.py)
-4. Under Event, go to Settings -> Upload Wallet Addresses - upload some ethereum addresses 
-
-
-You can now play with the event by clicking on the "Go to Shop" button at the top left (next to the event name)
-
-## Automatic payment confirmation with the `confirm_payments` command
-
-This plugin includes a [django management
-command](https://docs.djangoproject.com/en/2.2/howto/custom-management-commands/#module-django.core.management)
-that can be used to automatically confirm orders from the Ethereum address
-associated with each order across all events. By default, this command will perform a dry run
-which only displays payment records that would be modified and why but without
-actually modifying them.  
-
-Here's an example invocation of this command:
-```bash
-python -mpretix confirm_payments \
-    --no-dry-run
-```
-Note that this doesn't require you to pass any event slug, since it runs for all events at once. It inspects the address that was associated with each order (at
-the time the ticket was reserved) to determine if sufficient payments were made
-for the order.  It may check for an ethereum payment or some kind of token
-payment depending on what was chosen during the checkout process. It checks using the RPC URLs that were configured in the admin settings while setting up the event. If no rpc urls were set, then the command gives yet another chance to type in a rpc url (like infura). The `--no-dry-run` flag directs the command to
-update order statuses based on the checks that are performed.  Without this
-flag, the command will only display how records would be modified. 
-
-For more details about the `confirm_payments` command and its options, the
-command may be invoked with `--help`:
-```bash
-python -mpretix confirm_payments --help
-```
