Built for Backdrop Build, a four week hackathon focusin on AI and crypto projects.
The Escape Hatch is a browser extension that let's you send OP rollup bound transactions as censorship resistant Ethereum transactions. It works by intercepting transactions and rewriting them as depositTransaction calls on the relevant networks OptimismPortal contract.
The Escape Hatch by default intercepts browser wallet bound transactions, but mobile wallets can also be connected to it. Accordingly, you can also choose to connect to dapps via WalletConnect to the Escape Hatch so requests can be forwarded from them.
The easiest way to use the Escape Hatch is to install it from the Chrome Web Store.
Failing that (maybe the extension is still under review), you can clone this repository and run it locally.
git clone git@github.com:superbridgeapp/escape-hatch.git
cd escape-hatch
pnpm i
pnpm dev
Then you can load it as an extension
- Navigate to
chrome://extensionsin your browser - Toggle on
Developer Modein the top right of your screen - Click
Load unpacked - Select the
dist/directory of the folder you just ranpnpm devin
Right now the extension is limited to browser wallets, like MetaMask and Rabby, but it works best with MetaMask. Enabling users to connect their mobile wallets to the extension via WalletConnect would further increase the accessibility of censorship resistant transactions.
Blindly signing deposit transactions can be a scary experience for users. Building tooling that highlights what a deposit transaction will do on the destination chain will help users feel safe when approving these transactions.
Once WalletConnect support is live (specifically V2, where dapps and wallets maintain a mapping of networks supported), the extension will be able to precompute the L2 transaction hash and return that to the dapp so the dapp can wait for execution of the transaction.
