Espresso Shared Sequencer is a shared sequencing infrastructure provided by the Espresso network. It delivers unified transaction ordering and fast confirmations for multiple Layer 2 rollups, improving cross-chain interoperability and overall network security. As the Layer 2 rollup ecosystem continues to expand, more networks are running into challenges such as sequencer centralization, difficulty coordinating across chains, and delays in transaction confirmation. Traditional rollup architectures typically rely on independent sequencers. While this improves performance, it also makes it harder for different networks to coordinate execution, which ultimately hurts the user experience for cross-chain applications.

ESP is the native token introduced by Espresso Network to support the operation of its shared sequencing layer, including node staking, security mechanisms, and ecosystem incentives. As Espresso gradually transitions toward a decentralized Proof of Stake consensus model, ESP becomes a key component in maintaining network functionality and driving ecosystem growth.

Espresso is a foundational protocol built to enhance transaction ordering and cross-chain interoperability across Layer 2 rollups through a shared sequencing layer. As modular blockchains and multi-rollup ecosystems continue to expand, Espresso plays a coordinating role by aligning transaction order and data confirmation across different Layer 2 networks, improving both efficiency and security.

Lighter (LIT) is a next-generation decentralized exchange (DEX) that combines zk-rollup technology with a central limit order book (CLOB) model to deliver trading performance close to centralized exchanges (CEXs), while preserving on-chain asset self-custody and transparency. Its key strengths lie in low-latency matching, high throughput, and improved capital efficiency, positioning it as a strong contender in the perpetual futures (Perp) DEX space.

idOS serves as a reusable on-chain identity infrastructure within the stablecoin ecosystem, allowing users to share verified identity data seamlessly across various financial applications. Leveraging encrypted storage and access approval mechanisms, idOS enables stablecoin platforms to verify user identities without requiring repeated KYC procedures, which reduces compliance costs and improves the overall user experience. By introducing this identity layer, stablecoins can meet regulatory obligations while preserving user privacy, establishing themselves as a vital link between on-chain finance and the real world.

Nexira’s cross-game asset mechanism maps, transforms, and redistributes assets at the protocol layer, enabling them to move and function seamlessly across different games.

idOS operates on a core mechanism of "encrypted storage + access approval (Access Grant)." User identity data is initially verified by the issuer and then securely encrypted and stored within the idOS network. Applications, or consumers, can only access this information after receiving explicit user approval. This approach allows idOS to facilitate the reuse, privacy protection, and seamless transfer of identity data across multiple applications, enabling sensitive information like KYC to be safely utilized across various platforms without requiring users to resubmit their data.

idOS (IDOS) is a Web3 identity layer designed to offer users portable identity verification and self-custodial data storage, allowing KYC information to be seamlessly reused across multiple platforms. By binding identities to blockchain addresses, idOS resolves the challenges of fragmented identities and redundant verification processes in Web3, establishing itself as essential infrastructure that connects users, applications, and compliance systems within the stablecoin economy.

Following the user base surpassing 51 million, both user activity and trading depth increased in tandem. The spot market now supports over 4,500 assets, forming a broad and stable market foundation.

Gate, a leading global digital asset trading platform, has released its March 2026 Transparency Report.

Lighter’s workflow consists of order submission, off-chain matching, batch packaging and verification, and final on-chain settlement. User orders are first routed to the off-chain matching engine for efficient processing. The resulting trades are then bundled into the zk-rollup and validated using zero-knowledge proofs, with settlement ultimately completed on the main chain. This “off-chain matching + on-chain verification” architecture allows Lighter to deliver low-latency, high-throughput trading performance comparable to centralized exchanges, while maintaining robust security.

Lighter and Hyperliquid are both decentralized Perpetual Futures (Perp) trading platforms, yet their architectural designs are fundamentally different. Lighter employs a hybrid model featuring off-chain matching and zk-rollup verification, whereas Hyperliquid leverages a proprietary high-performance chain for on-chain matching and execution. These distinctions result in varying trade-offs regarding performance, decentralization, scalability, and user experience. Gaining insight into these two approaches is essential for understanding the future trajectory of next-generation high-performance DEXs.

NEXI plays a central role within the Nexira system as the value-connecting tool at the protocol layer, supporting the transfer, pricing, and overall operation of cross-game assets.

Through asset tokenization and a Proof of Reserve mechanism, GoldFinger brings gold into the DeFi ecosystem, allowing it to take part in on-chain financial activity as collateral, a liquidity tool, and a component of yield strategies. Once tokenized, gold assets such as ART can function as collateral, liquidity instruments, and building blocks in yield strategies across lending markets, decentralized exchanges, and structured returns, turning a traditional store of value into composable on-chain financial infrastructure.

Nexira DAEP (NEXI) is a blockchain protocol built to enable cross-game digital asset trading and interoperability. Through a unified asset economy model, it allows tokens, items, and NFTs from different games to be used and circulated within the same system. As Web3 gaming evolves, assets are gradually moving from closed systems into open networks, and protocols like this are designed to connect asset relationships across different games.
