**Ecosystem Support Program (ESP)**

ESP is the public-facing allocation arm of the Ethereum Foundation focused on strengthening Ethereum's foundations and enabling future builders: improving infrastructure, expanding the range of tools available to those building on Ethereum, deepening our understanding of cryptographic primitives, and growing the builder ecosystem through education and community development.

[Website](https://esp.ethereum.foundation/) | [Twitter](https://twitter.com/ef_esp)

🏆 **Prize - Account Abstraction: Wallets, Paymasters, & Developer Tooling**

We encourage building in any of the 3 domains listed below, and recommend using [Trampoline](https://github.com/eth-infinitism/trampoline) for all domains. The top 4 projects submitted (regardless of domain) will each receive $2,500. 

**Wallets:** Demonstrate creative use of ERC-4337 (e.g. an innovative recovery method, access control, privacy, automation).

**Paymasters:** An interesting implementation of a paymaster contract into an application flow (e.g. Sybil-resistant gas sponsoring, paymasters swapping tokens for ETH) or tools for paymasters to manage their paymaster contract.

**Developer Tooling:** Simplify the developer experience by enhancing an existing devtool to support ERC-4337 (e.g. Hardhat plugin, ethers.js support) or create a new devtool to support ERC-4337.

**Privacy & Scaling Explorations (PSE)**

The PSE team explores new use cases for zero-knowledge proofs and other cryptographic primitives through research and proof-of-concepts.

1. Build on MetaMask SDK 

We have $3k max for up to 2 winners ($1.5 each or $3k for one team).

Beyond your winnings, you have the opportunity to work alongside ConsenSys post-hackathon to apply for a MetaMask Grant or be part of our Ambassador or Accelerator program. We want to build with you, and with a well-fleshed-out submission, we can help you take your idea to the next level, finish those features you couldn’t get to, or take your project to production.

Valid submissions must include one of the various MetaMask SDKs at minimum, enabling users to connect to MetaMask Extension and/or MetaMask Mobile (Unity, JavaScript, React Native/iOS)

Requirements:

Use the MetaMask SDK in your code

Each submission should have a short video that describes scope and functionality of the dapp 

Code available on GitHub

Derp: Repos must contain a text file named “tokyo.txt” with the phrase “Keep calm and love Tokyo” 

This attention to detail helps us reward genuine effort and identify quality projects. 

Helpful materials:

Metamask SDK Documentation: https://c0f4f41c-2f55-4863-921b-sdk-docs.github.io/guide/metamask-sdk-intro.html

Metamask SDK Dev Guide: https://dev.to/metamask/metamask-sdk-dev-guide-4f6m

Criteria:

2. Best Snap Use-case

We have $3k max for up to 2 winners ($1.5 each or $3k for one team).

Extend the functionality of MetaMask. The most popular wallet is now an extensible platform for permissionless innovation. Bring your features and APIs to MetaMask with Snaps. A Snap is a program run in an isolated environment that customizes and extends the wallet experience. We are looking for new and interesting use cases to modify MetaMask using Snaps.

Requirements

Novel - We are looking for new and interesting use cases made possible only via the Snaps platform. Snaps must extend wallet functionality in a meaningful way. Simple use cases where the dapp could have existed without a Snap will not be awarded.

Derp - Repos must contain a text file named “tokyo.txt” with the phrase “Keep calm and love Tokyo” This attention to detail helps us reward genuine effort and identify quality projects.

Monorepo - Use a monorepo structure (scaffold projects with the guide or the CLI to get started). Feel free to construct a more complex front-end React.

README - README should detail what the project is, what it aims to accomplish, steps for running locally etc.

Run It - Submissions must hosted or runnable locally

The winning project that launches their dapp within 2 months after the hackathon will have their projects fast tracked for consideration in the MetaMask Grants DAO.
