Polygon Deploys Amoy Testnet

·

The Ethereum ecosystem continues to evolve at a rapid pace, with major developments shaping the future of decentralized applications, staking infrastructure, and institutional adoption. Among the most impactful recent updates is Polygon’s deployment of the Amoy testnet, a critical step in strengthening developer tools and ensuring long-term compatibility with Ethereum’s evolving network standards.

This article explores the significance of Polygon’s new testnet, examines Larry Fink’s endorsement of an ETH ETF, reviews Tenderize’s V2 mainnet launch, and analyzes EtherFi’s growing traction in the liquid staking space. Whether you're a developer, investor, or blockchain enthusiast, these updates offer valuable insight into the current momentum of Ethereum-based innovation.

What Is the Polygon Amoy Testnet?

Polygon has officially launched Amoy, a new Sepolia-based testnet designed specifically for its Polygon PoS chain. With chain ID 80002, Amoy replaces the aging Mumbai testnet, which relies on Ethereum’s soon-to-be-deprecated Goerli testnet. As Ethereum phases out Goerli in 2025, Polygon is proactively migrating its core development infrastructure to ensure continuity and stability.

Amoy serves as the primary sandbox environment for developers building on Polygon, offering improved reliability, updated tooling, and seamless integration with modern Ethereum development workflows. Key features include:

While both Amoy and Mumbai will run in parallel during the transition period, developers are strongly encouraged to migrate their decentralized applications (dapps) to Amoy. This ensures uninterrupted testing and future-proofing against network deprecations.

For teams relying on automated testing pipelines or CI/CD environments, early migration minimizes friction and avoids potential downtime once Mumbai is fully retired.

Why Larry Fink’s Support for an ETH ETF Matters

In a recent CNBC interview, BlackRock CEO Larry Fink expressed strong support for an Ethereum ETF, calling it a natural progression in the broader movement toward tokenization of real-world assets. As the head of the world’s largest asset manager—overseeing $9.42 trillion in assets—Fink’s statements carry significant weight in financial markets.

Fink highlighted how blockchain technology enhances transparency and reduces systemic corruption through immutable record-keeping and automated settlement processes. His endorsement follows BlackRock’s successful launch of the iShares Bitcoin Trust (IBIT), which saw over $1 billion in trading volume on its first day after SEC approval.

While no official filing for an ETH ETF has been submitted yet, Fink’s comments signal growing institutional interest in Ethereum’s long-term value proposition beyond speculative trading. An approved ETH ETF could unlock billions in capital from traditional finance (TradFi) investors seeking regulated exposure to smart contract platforms.

Ethereum’s price responded swiftly to the news, briefly surging to $2,698, reflecting market confidence in Ethereum’s maturation as a foundational digital asset.

Tenderize Launches V2 on Ethereum and Arbitrum

Liquid staking protocol Tenderize has announced the mainnet launch of Tenderize V2 on both Ethereum and Arbitrum, marking a major upgrade in staking flexibility and yield optimization. The release introduces validator-specific liquid staked tokens, known as tTokens, allowing users to maintain alignment with individual validators while retaining liquidity.

This advancement addresses a key limitation in earlier liquid staking models, where token fungibility obscured validator identity and reduced accountability. With tTokens, stakers gain greater transparency and control over their delegation choices.

To incentivize early participation, Tenderize is launching a three-month staking campaign that rewards users with governance tokens. A portion of these tokens will also be allocated to early adopters of Tenderize V1, recognizing their contribution to the protocol’s growth.

Users can expect to claim their governance tokens during a Token Generation Event (TGE) scheduled at the end of the campaign. This phased distribution model promotes long-term engagement and decentralization of protocol governance.

EtherFi Reaches 65,000 Staked ETH Milestone

EtherFi, a leading liquid staking protocol integrated with EigenLayer, has surpassed 65,000 ETH in total value locked (TVL), exceeding $170 million in deposits. This surge follows the announcement of its upcoming token generation event in April 2025, which has galvanized community interest.

Holders of EtherFi’s native staking token, eETH, earn dual rewards through point accumulation in both the EtherFi and EigenLayer ecosystems. These points are expected to translate into future token allocations, creating a powerful incentive for early adopters.

Beyond staking rewards, EtherFi is preparing to unveil its full governance framework and tokenomics model in the coming months. The protocol aims to establish a decentralized autonomous organization (DAO) structure that empowers users to shape its evolution.

With native restaking on EigenLayer, EtherFi enables users to secure additional protocols while maintaining liquidity—representing a new frontier in modular blockchain design.

Frequently Asked Questions

Q: What is the purpose of the Polygon Amoy testnet?
A: Amoy provides developers with a stable, up-to-date environment to build and test dapps on Polygon PoS using Ethereum’s Sepolia testnet as its root chain, replacing the deprecated Goerli-based Mumbai testnet.

Q: When will the Mumbai testnet be discontinued?
A: While no exact shutdown date has been confirmed, Mumbai will be phased out gradually as developers migrate to Amoy. Both networks are currently operational to ensure a smooth transition.

Q: What are tTokens introduced by Tenderize V2?
A: tTokens are validator-specific liquid staked tokens that allow users to retain identity and alignment with individual validators while enabling liquidity and composability across DeFi platforms.

Q: How can I participate in EtherFi’s token generation event?
A: Users who hold eETH before the snapshot date will earn points in both the EtherFi and EigenLayer ecosystems, which are expected to qualify them for a token allocation during the TGE.

Q: Is BlackRock launching an ETH ETF soon?
A: As of now, BlackRock has not filed for an ETH ETF. However, CEO Larry Fink’s public support suggests the firm may consider one in the future as regulatory clarity improves.

Q: Why is EigenLayer important for EtherFi?
A: EigenLayer enables restaking, allowing ETH stakers to reuse their economic security to protect additional protocols. EtherFi leverages this capability to offer enhanced yields and deeper ecosystem participation.
