ETHTallinn 2024

Showcase your skills by building decentralized infrastructures focused on inclusivity, accessibility, and ownership. Build a better user experience across the web by utilizing account abstraction, and similar technologies.

Decentralized Infrastructure

Explore the potential of technologies that prioritize privacy and security to create a safe and secure social and infrastructure environment backed by web3 technologies.

Privacy, Security, and Reliability

Improve the performance and efficiency of nodes and infrastructure, as well as explore Layer 2 solutions and interoperability between different blockchains.

Scalability

## Task Description
Participants are tasked with developing a system that automates the process of receiving and sending payments on the Ethereum network, working with both ETH and ERC20 tokens.
The system can make payouts at a set interval and must ensure optimal (minimal) transaction fees, including through payouts aggregation and the use of gas optimization mechanisms.



## Technical Requirements
Multi-Deposit Addresses: Develop a management mechanism for multiple deposit addresses for receiving funds.
Payout Aggregation: The system should analyze incoming payments and aggregate them to minimize transaction costs when sending.
Fee Optimization: Include algorithms for calculating the optimal time and method of sending transactions to minimize gas costs.
Management of the Aggregating (Master) Address Balance: Integrate a mechanism for using ETH from the master address to pay for transaction fees, if necessary to optimize transaction costs.

Coinspaid Challenge: $5,000

The top 3 winners of the Hackathon will each receive $5,000 in Audit Credits. These credits can be claimed at any time to obtain a premium and highly recognized smart contract audit.

NOTE - this isn't a cash payment, it's a redeemable credit for your audit with Cyberscope.

## Description
tea Protocol offers a prize pool of $1k in USDC & TEA Tokens staked to the top projects building on open-source to be submitted to the tea Protocol.

## Requirements:
Your project must:
- Be built and managed on GitHub
- Utilize one of our eligible package managers (NPM, Homebrew, Crates, Pypi, Pkgx, APT, RubyGems)
- [Sign up for tea](https://app.tea.xyz/sign-up?r=zCfqrDgh7IR) and register your project through our platform (if it's a brand new project, you won't be able to register it yet, but still submit it to our bounty and we can provide registration support).

Build an Open-Source Web3 Project & Submit it to tea

## Description:
We invite you to write an Ocean Adapter for an external DeFi protocol of your choosing. This means you are free to select any project you prefer and create an integration for it. Projects that have already been integrated within Shell and can serve as examples and inspiration include Uniswap, Aave, Curve, Balancer, and Sushiswap. For more details on how to write Ocean Adapters and ideas, check the [Shell Developer Hackathon Cheat Sheet](https://docs.google.com/document/d/1aiS-dfjWg3PLErCiKbAJ0Fb_FC8IjtD5TYAop5tpsII/edit?usp=sharing).

## Challenge: The best integration of an external DeFi protocol
🥇 1st Place - $3000
🥈 2nd Place - $1,500
🥉 3nd Place - $500

## Submission Essentials:
The project has to be an Ocean Adapter, i.e. integration of an external protocol.
Developers must demonstrate that the contracts are working.
A well-documented process in the project's README.md on how to run and test the project locally.
Open source - The code must be available on GitHub.
A demo recording would be nice, but it's not mandatory (no longer than 5 minutes).

## 🏆 Evaluation Criteria:
Technical implementation.
Relevance of the integrated project to the Shell ecosystem.

The best integration of an external DeFi protocol

Galadriel is the first Layer 1 for AI.

Galadriel enables developers to build decentralized AI apps/agents, just like Ethereum has enabled building d(apps). For example, you can now build genAI NFTs, on-chain ChatGPT, DAOs ran by agents, build agent swarms and even on-chain games with AI NPCs - your imagination is the limit.

Galadriel is built on a parallel-execution EVM stack which enables high throughput and has a familiar devexp for all the Solidity devs. It brings AI inference on-chain in a low-cost, low-latency manner through teeML (Trusted Execution Environment Machine Learning) implementation which allows to query any open and closed-source LLM models in a verifiable manner. Galadriel’s L1 stack enables developers to build on-chain AI agents & apps like smart contracts for the first time.

Galadriel is in devnet phase which means things evolve fast and might break. Join the mission of building safe, user-owned AI.
