# Testnet Data Room

EigenFi Vaults provide a decentralized, non-custodial, and yield-optimized staking solution across multiple blockchain ecosystems. By leveraging EigenLayer’s Actively Validated Services (AVSs) and advanced modular staking mechanisms, EigenFi Vaults enable users to deposit liquid staked assets and earn rewards while securing emerging decentralized networks. Each vault is tailored to its respective blockchain, ensuring optimal integration and security while maintaining seamless user experience.

### Supported Chains

#### [1. **Ethereum Vault (Sepolia Testnet)**](/getting-started-on-helix/testnet-data-room/ethereum-vault.md)

* **Asset Supported:** stETH (Liquid Staked ETH - Sepolia Testnet Version)
* **Mechanism:** Users deposit stETH into the EigenFi Ethereum Vault to participate in EigenLayer's restaking economy. This vault enhances Ethereum’s security while enabling users to earn staking rewards and EigenLayer incentives.
* **Use Cases:** Yield generation, AVS security provisioning, Ethereum restaking economy participation.
* **Security Model:** Smart contract-based restaking with slashing-resistant mechanisms and multi-signature governance.

#### 2. [**Movement Vault (Bardock Testnet)**](https://docs.helixlabs.org/getting-started-on-helix/eigenfi-vaults/movement-vault)

* **Asset Supported:** stMOVE (Liquid Staked MOVE - Bardock Testnet Version)
* **Mechanism:** This vault integrates with the Movement Network, a Move-centric ecosystem. Users deposit liquid staked Move assets to secure AVSs and decentralized infrastructure on Movement.
* **Use Cases:** Liquidity provisioning for Move-based applications, staking rewards optimization, AVS participation.
* **Security Model:** Move-based security framework with smart contract-controlled slashing conditions.

#### 3. [**BNB Chain Vault (Testnet)**](https://docs.helixlabs.org/getting-started-on-helix/eigenfi-vaults/bnb-chain-vault)

* **Asset Supported:** stBNB (Liquid Staked BNB - Testnet Version)
* **Mechanism:** The EigenFi BNB Chain Vault enables users to stake their liquid staked BNB assets to support EigenLayer-compatible AVSs. It provides additional yield opportunities while maintaining liquidity for DeFi applications.
* **Use Cases:** BNB staking yield maximization, AVS security enhancement, DeFi composability.
* **Security Model:** BNB Chain-native smart contracts with secure restaking parameters.

#### 4. [Bitlayer Vault (Testnet)](https://docs.helixlabs.org/getting-started-on-helix/eigenfi-vaults/bitlayer-vault)

* **Asset Supported:** stBTC (Liquid Staked BTC as ERC-20 on Bitlayer - Testnet Version)
* **Mechanism:** As a Bitcoin Layer 2 solution, Bitlayer enables BTC holders to participate in staking activities. EigenFi Vault allows restaking of liquid staked BTC, securing AVSs and expanding Bitcoin’s economic utility in DeFi.
* **Use Cases:** Bitcoin DeFi expansion, AVS-backed security provisioning, yield-enhanced BTC staking.
* **Security Model:** Bitlayer-native verification with BTC-backed security guarantees.

#### 5. [**Cardano Vault (Preprod Testnet)**](https://docs.helixlabs.org/getting-started-on-helix/eigenfi-vaults/cardano-vault)

* **Asset Supported:** tADA (Preprod Testnet Version)
* **Mechanism:** The Cardano-based EigenFi Vault enables ADA holders to restake their assets within a modular staking ecosystem. It enhances security across Cardano-compatible AVSs while ensuring users earn compounded staking yields.
* **Use Cases:** Cardano staking enhancement, liquid restaking rewards, AVS support.
* **Security Model:** Smart contract-based staking on Cardano with governance-controlled risk mitigation.

### Conclusion

EigenFi Vaults serve as a bridge between traditional liquid staking and the emerging restaking economy powered by EigenLayer AVSs. By supporting multi-chain integrations across Ethereum, Movement, BNB Chain, Bitlayer, and Cardano, EigenFi ensures that stakers maximize their rewards while contributing to the decentralization and security of blockchain networks.
