When Ethereum (ETH) completed its transition to a Proof-of-Stake (PoS) consensus model in September 2022, it was widely anticipated that the well-known issues of network congestion and high gas fees would significantly improve. However, reality has shown otherwise, as both of these challenges, particularly the problem of high fees, persist to this day.
This ongoing situation has brought increased attention to Ethereum’s Layer 2 protocols, which aim to address both major concerns. Many of these Layer 2 platforms offer substantial improvements in scalability, speed, and cost-effectiveness, leading to fierce competition in the race to become the most efficient solution. Among these platforms, Metis stands out as a clear leader when it comes to reducing transaction costs—an issue that remains critical for the majority of Ethereum users.
Metis, also known as Metis Andromeda, is a scalable Layer 2 solution for Ethereum that boasts the lowest transaction fees in this competitive space.
Its hybrid rollup architecture uniquely combines features of both Optimistic Rollups and Zero-Knowledge (ZK) Rollups. This enables the platform to achieve impressive speed and cost efficiency, while also enhancing security and transaction privacy.
In addition to these attributes, Metis offers several other unique features, including EVM equivalence, decentralized autonomous processing, and decentralized storage solutions.
What is Metis Andromeda?
Metis (METIS), also referred to as Metis Andromeda, is a Layer 2 platform built on Ethereum, offering a range of features such as Ethereum Virtual Machine (EVM) equivalence, full decentralized autonomy, decentralized storage, and a hybrid rollup mechanism. Its unique rollup architecture combines key aspects of two prominent rollup models—Optimistic Rollups and Zero-Knowledge (ZK) Rollups.
In November 2021, Metis launched its mainnet operations, establishing itself as a popular Optimistic Rollup protocol similar to Optimism. Over the past two years, the development team has gradually integrated crucial features that set Metis apart from other Layer 2 protocols.
While many other Ethereum Layer 2 platforms use EVM-compatible processing mechanisms, Metis’ engine, known as the Metis Virtual Machine, is an EVM equivalent. This equivalency allows for near-perfect compatibility with the Ethereum network.
Currently, Metis offers users the lowest transaction costs among the leading Ethereum Layer 2 solutions. A major contributor to this cost-effectiveness is Metis’ decentralized storage model, which leverages the InterPlanetary File System (IPFS), a peer-to-peer architecture.
Rather than relying on centralized storage and off-chain data processing, Metis bundles large amounts of fraud-resistant data and transactions, enabling faster and cheaper data handling. Since the data is distributed across multiple nodes within the IPFS network, the risks of data breaches or loss are minimized.
What is Metis striving to achieve?
The primary goal of Metis aligns with that of other Layer 2 solutions—dramatically reducing transaction speeds and fees on Ethereum. However, due to its unique architecture, Metis has emerged as the most successful platform so far in minimizing transaction fees while maintaining ultra-fast processing times.
Most of the leading Layer 2 protocols integrated into Metis enable transactions to be completed almost instantly or within a few seconds. There are some issues related to transaction finality, which will be discussed below, but overall, Layer 2 protocols offer Ethereum users a fast and convenient experience.
These platforms have also succeeded in slashing Ethereum’s often excessive transaction fees. Although all major Layer 2 platforms provide significantly lower fees compared to direct transactions on Ethereum, Metis has managed to bring these costs down to mere fractions of a percent. As of early November 2023, the average transaction fee on Metis for ETH transfers is less than one cent, while token swaps cost just four cents. In both cases, Metis has outpaced its competitors significantly.
How does Metis work?
The core functionality and efficiency of Metis are based on two critical elements: a smart Layer 2 solution and a hybrid rollup mechanism. Let’s dive deeper into these two concepts that power the Metis platform.
Layer 2 Smart Solution
Metis’ scaling solution offers a unique decentralized processing model.
In a typical Layer 2 solution (particularly in an Optimistic Rollup, which Metis was forked from), transaction bundles are sent to a sequencer, a centralized entity in the network. The sequencer places transactions on the Layer 2 Ethereum network, where they are verified and recorded in an immutable ledger. If a Layer 1 validator detects fraud by identifying data inconsistencies, transactions are rejected. The process of fraud proofs on Layer 1 consumes resources from the underlying blockchain, resulting in inefficiencies.
Metis’ sequencing, however, is only one part of its broader decentralized network used for transaction processing. In Metis, a network participant, or block producer, maps transaction data and distributes it across a peer-to-peer network. These peers in the decentralized network serve as the first line of defense against fraudulent transactions.
Once the decentralized network approves the transactions, the sequencer (a part of this peer-to-peer system) submits the transactions to decentralized storage (see above) while simultaneously notifying the Layer 1 validator by sending transaction metadata. The Layer 1 validator can access the data from decentralized storage, verify its consistency with the metadata, and either approve the transactions or raise a fraud proof.
This pre-validation by the peer network, along with decentralized storage, significantly reduces the load on Layer 1, helping to minimize instances of fraud.
Hybrid Rollups
Similar to other standard rollup protocols, Metis aggregates transactions for batch submission to Layer 1. However, Metis’ rollup model is built on a unique hybrid configuration, enabling the platform to achieve industry-leading transaction fee reductions while maintaining rapid transaction confirmation times. The rollup architecture in Metis integrates elements from both Optimistic Rollups and Zero-Knowledge (ZK) Rollups.
Optimistic Rollups rely on fast and cost-effective transaction processing, bundling transactions onto the underlying Layer 1 without providing validity proofs upfront. Validators on Layer 1 have up to a week after submission to submit fraud proofs if any inconsistencies are found. Note that while confirmation of a transaction (i.e., its execution and verification on the Layer 2 protocol) occurs within seconds on Optimistic Rollups, the time it takes for finality is another issue that we’ll address next.
Finality refers to the point when a transaction is permanently recorded in the Layer 1 ledger. Between confirmation and finality, the transaction can be reversed if Layer 1 validators reject it.
While Optimistic Rollups offer quick confirmations, their finality period spans a week—the timeframe in which Layer 1 validators can submit fraud proofs.
ZK Rollups, on the other hand, don’t rely on fraud proofs. Instead, they require transaction batches sent to Layer 1 to already include validity proofs. As a result, there is no mandatory (and lengthy) period during which validators can flag a transaction batch for inconsistencies or fraud. This allows ZK Rollups to achieve significantly faster transaction finality compared to Optimistic Rollups, though the latter still provides quicker confirmations and lower processing costs. ZK Rollups also offer enhanced data privacy and security compared to their Optimistic counterparts.
By combining elements of both Optimistic and ZK technologies, Metis offers low-cost transactions with confirmation times of just a few seconds, while also reducing the finality period from seven days to approximately four hours.
Key Features of Metis
Decentralized Autonomous Company (DAC) Structure
Metis aims to leverage community-based governance, but instead of using a traditional Decentralized Autonomous Organization (DAO) model, it employs a Decentralized Autonomous Company (DAC) framework.
In a typical DAO, governance decisions are made based on the amount of crypto tokens held or staked by a node. The more tokens a participant has, the greater their influence in voting and decision-making processes. This can lead to issues where significant control is concentrated in the hands of large token holders, sometimes referred to as “whales,” potentially skewing the governance process.
Additionally, some DAO participants may lack the expertise or interest necessary to make informed decisions on technical proposals.
Metis addresses these challenges through its DAC model. Governance rules within DAC can be predefined by developers using smart contracts, often modeled after traditional corporate structures. For example, DAC rules might specify which user groups are eligible to vote on particular technical proposals, ensuring that only those with relevant knowledge participate in decision-making.
The DAC model of Metis revolves around two main components: General and EcoNodes. Anyone can initiate a DAC and submit proposals. By staking METIS tokens, users can earn veMETIS, which grants them the ability to vote on governance matters. EcoNodes, which hold more significant voting power, are chosen by existing EcoNodes based on their contributions to the Metis ecosystem.
This structure helps maintain an efficient, well-organized, and comprehensive decentralized business model.
Metis Virtual Machine (MVM)
The Metis Virtual Machine (MVM) is the computational engine of the Metis platform, designed to achieve full equivalence with Ethereum’s EVM (Ethereum Virtual Machine). This compatibility allows blockchain developers to deploy Ethereum-native applications on Metis with minimal code modification. It also simplifies the testing and migration of applications between layers.
Bridges
Users can utilize several bridges to facilitate the transfer of tokens into and out of the Metis ecosystem. The primary bridge is the Metis Bridge, which supports asset transfers between Metis and Ethereum. In addition to the native METIS and ETH tokens, the bridge supports various popular Ethereum-based tokens such as USDT, USDC, LINK, DAI, AAVE, and WBTC.
For NFT transfers, the Metis NFT bridge supports both ERC-721 and ERC-1155 token formats.
A notable limitation of the Metis Bridge is its inability to directly transfer METIS tokens between blockchain environments outside Ethereum. However, Metis has implemented the omnichain token transfer protocol — LayerZero — which enables asset transfers across multiple blockchain platforms. Through third-party bridges that integrate LayerZero, assets can be moved between Metis and other platforms such as Polygon (POL), Avalanche (AVAX), Fantom (FTM), BNB Chain (BNB), Arbitrum (ARB), and more. Among these, Synapse Bridge offers the broadest range of transfer options for Metis, covering all the aforementioned networks.
What is the METIS Token?
The METIS token is the native asset of the Metis platform, designed to be compatible with ERC-20 standards and integral to the Layer 2 protocol. The METIS token serves multiple functions within the ecosystem, including covering transaction fees, staking, and facilitating the launch of Decentralized Autonomous Companies (DACs).
The total supply of METIS is capped at 10 million tokens. As of now, the overall supply stands at 5,410,000, with a circulating supply of just over 4.3 million tokens.
Upon its launch in May 2021, METIS was initially distributed according to a predefined allocation plan. The remaining tokens will be allocated through various mechanisms, such as community rewards, ecosystem development, and transaction-related mining activities.
Is METIS a Good Investment?
In the long run, METIS could emerge as one of the top altcoin investments in the Layer 2 cryptocurrency sector. Its strong performance in minimizing transaction fees positions it as a promising option for Ethereum users, potentially attracting a growing user base over time. However, achieving widespread recognition and adoption for the platform may take some time.
The Metis platform’s EVM-equivalent Metis Virtual Machine (MVM) is likely to be well-received by decentralized application (DApp) developers, simplifying the testing and migration of Ethereum applications.
Nevertheless, METIS operates in a competitive landscape of Ethereum Layer 2 solutions, where established players like Optimism, Arbitrum, and Polygon are fiercely defending their user bases. Gaining a substantial user following may require a more extended period. Therefore, METIS is more suited for long-term investment rather than quick gains.
