Shortcuts

Shortcuts – The Public Good for onchain interactions.

Shortcuts allows users to combine onchain contract calls into a shortcut, which will be executed on the given chain with some constant, pre-set or variable parameters.

Examples include:

• using a bridge to send ETH to Base / Optimism
• calling a token swap contract (approve + swap)
• donate erc20 / eth
• using any investment strategy

See it in action!

We've prepared some action for you to try

• Donate us some ETH on Base

• Donate us some USDbC on Base

• Donate us some ETH on Optimism

• Donate us some OP on Optimism

• Bridge ETH to Base

• Bridge ETH to Optimism

Notes

The best experience is achieved when using the Safe as the shortcut is being run in a single transaction.

Users can also share shortcuts with pre-set values. Those links can be included on public pages (like bridge dApp or blog or github profile or twitter) to be quickly executed later via familiar interface.

• Each shortcut is published on EAS where it can later be inspected. Before executing a shortcut users can run a simulation (using Tenderly) to make sure that interaction is safe
• Users can make send upvotes (attestations) to recognize a specific shortcut onchain.
• Developers can build shortcuts for their existing dApps and publish them for the community to use.
• Generally the app works with any chain
• Shortcuts consist of list of actionsю Each action references a call of a specific contract with arbitrary parameters
• To run the shortcuts users can use connected EOA, owned safe, or use Shortcuts app via Safe app interface.
• Shortcuts support templating action values, ENS resolving
• There's no db used – only EAS + IPFS making Shortcuts basically the Public Good
• Created shortcuts can be shared to other users or used as a link to be used on a website. Linked shortcut can include some pre-set values

Details

Contracts:

• foundry (+openzeppelin) to develop some demo contracts + Donation contract
• deployed to Base/Optimism +testnets

Web:

• vite + react + @chakra-ui + react-router
• rainbowkit + wagmi + viem
• safe sdk

Other:

• eas-sdk to interact with EAS
• web3.storage for ipfs
• apollo to access EAS GraphQL API
• Tenderly for simulation
• Etherscan APIs to resolve ABIs

Further development will include:

• crosschain shortcuts and actions
• gasless execution

Development

# setup env
cp .env.develop .env
# then configure all the values in .env

# install deps
yarn

# run dev
yarn dev

There are constants you can update to target either Sepolia or Optimism EAS.
