Description

🌐 CORO TASHI β€” The Future of Staking

πŸš€ Introduction

Coro Tashi is a next-generation DeFi staking protocol built on the Core Chain by CoreDAO. It empowers users to:

  • Stake CORE tokens

  • Receive liquid stCORE tokens

  • Earn auto-compounding rewards
    β€”all without lockups or intermediaries.

Built with security, transparency, and user-friendliness at its core, Coro Tashi leverages the power of the Core blockchain to redefine staking.

✨ Key Features

  • πŸ”„ Liquid Staking: Stake CORE β†’ Get stCORE β†’ Stay liquid while earning.

  • πŸ“ˆ High Yield: Dynamic APY pools + Boost multipliers = Maximized rewards.

  • πŸ”’ Secure: Non-custodial, audited smart contracts with complete on-chain transparency.

  • 🌐 Decentralized: Open-access staking pools with no middlemen.

  • πŸ”” On-Chain Notifications: Get alerts for deposits, withdrawals, and updates.

  • πŸ–₯️ User-Friendly Dashboard: Stake, claim, and manage positions effortlessly.

βš™οΈ How It Works

  1. Deposit CORE into a staking pool.

  2. Receive stCORE (your liquid staking token).

  3. Earn rewards auto-compounded based on pool APY.

  4. Unstake anytime (post lock period) or use emergency withdrawal with a penalty.

  5. Claim rewards whenever you like.

Progress During Hackathon

Day 1: The team aligned on the architecture, and we divided the work among frontend, smart contracts, and deployment. We finalized the staking model β€” stake CORE, receive stCORE, earn rewards with no lockup. We began working on the initial smart contract structure using Solidity and set up the Core Testnet environment. Day 2: Implemented the smart contracts for deposit, withdraw, and claim functions. All contracts were written to support auto-compounding and reward calculations. Security was a priority β€” contracts were non-custodial, and we ensured on-chain transparency. The contracts were deployed on Core Testnet 2, and test tokens were minted for simulation. Day 3: The frontend team built the staking UI using React and Ethers.js, and connected the Web3 wallet functionality. We integrated MetaMask for seamless user interaction and ensured smooth testnet onboarding. Users could now stake TBTC, view their stCORE balance, and withdraw or claim rewards from the interface. Day 4: Finished the backend logic for reward distribution and APY calculations. Added boost multipliers and penalty-free unstaking logic. UI enhancements were made to improve clarity and responsiveness. We also deployed the front-end to Vercel (coro-tashi.vercel.app) and wrote complete technical documentation on GitBook. Final Day: We tested the full staking lifecycle: deposit TBTC, earn TASHI rewards, claim or withdraw. All functions were verified on Core Testnet. Smart contract events were emitting correctly, and the system was stable. We wrapped up by preparing a clean demo, final pitch, and submitting the GitHub repository.

Fundraising Status

Successfully raised $1.5K and shipped to Testnet. Currently in discussions with the core and marketing teams to prepare for the Mainnet launch and the next round of fundraising.
