Tonviewer is a block explorer and on-chain analytics platform built specifically for the TON (The Open Network) blockchain. It allows users to inspect transactions, wallet addresses, smart contracts, and network statistics such as live TPS, Toncoin price, and market cap. The platform is part of the Tonkeeper ecosystem and serves both retail users and developers who need transparent access to TON blockchain data. Beyond raw chain data, Tonviewer hosts a curated dApp catalog covering wallets, DEXes, DeFi protocols, games, and utilities within the TON ecosystem.

TRISA (Travel Rule Information Sharing Architecture) is an open protocol and developer framework that enables Virtual Asset Service Providers (VASPs) to comply with FATF and FinCEN Travel Rule requirements for cryptocurrency transaction identity information. The protocol is defined as a gRPC API using protocol buffers, allowing language-agnostic, peer-to-peer identity data exchange between VASPs without modifying underlying blockchain protocols or adding transaction costs. TRISA provides an open-source node implementation called Envoy that supports both the TRISA and TRP (Travel Rule Protocol) standards. The specification is governed by the TRISA Working Group operating under the travelrule.io umbrella, with reference implementation published in Go on GitHub under an open-source license. Primary users include crypto exchanges and custodians.

Trusta.AI is an on-chain identity and reputation protocol that performs Sybil detection, proof-of-humanity verification, and wallet reputation scoring for cryptocurrency users and AI agents. The platform comprises three primary components: TrustGo, an identity wallet and reputation scoring dashboard; TrustScan, which provides on-chain attestations, proof-of-humanity verification, and humanity testing tools; and AgentGo, an AI agent identity verification and tracking layer. The system analyzes wallet activity across EVM and TON blockchains to generate reputation scores and issue fully on-chain attestations. Trusta integrates with zero-knowledge infrastructure, including Brevis Network, to enable verifiable credential generation. The protocol is designed for Web3 protocols, airdrop campaigns, and decentralized finance applications requiring distinction between human users and automated accounts.

VASPnet is a regulatory data platform that aggregates and provides structured information on Virtual Asset Service Providers (VASPs) for use in compliance and risk assessment workflows. The platform is designed to help financial institutions, compliance teams, and crypto businesses evaluate counterparty risk by supplying standardized regulatory and operational data on VASPs globally. Its core product differentiator is the focus on VASP-specific regulatory metadata, enabling due diligence processes required under frameworks such as the FATF Travel Rule. VASPnet has partnered with blockchain analytics firm Elliptic to integrate its data into crypto risk assessment tooling, indicating its positioning as a data infrastructure provider for institutional compliance use cases.

ViewBlock is a multi-chain block explorer that provides on-chain data visibility for a range of blockchain networks including THORChain, Arweave, Zilliqa, Starknet, KYVE, and Arkeo. The platform allows users to browse transactions, addresses, and network activity across supported chains through a unified web interface. It is designed for general blockchain users, developers, and researchers who need transparent access to on-chain data without running their own nodes. ViewBlock operates as an independent analytics and exploration tool, serving both retail users and technical audiences across the crypto ecosystem.

Vyper is an open-source smart contract programming language for the Ethereum Virtual Machine that uses Python-like syntax. The language prioritizes security, readability, and gas efficiency through several built-in mechanisms. It includes automatic overflow checking, bounds checking, and a @nonreentrant decorator for reentrancy protection. These features are designed to eliminate certain classes of vulnerabilities at the language level, reducing the scope of potential security issues. Vyper is compatible with development frameworks including Foundry, Hardhat, Remix, and Apeworx. The compiler has undergone independent security audits by third-party firms. The language is used in smart contract development, particularly by projects requiring formal security guarantees and developers with Python experience.

Whale Alert is a blockchain transaction monitoring service that tracks and broadcasts large cryptocurrency transfers in real time across major networks including Bitcoin, Ethereum, USDT, USDC, and others. Its core product is an alert dashboard that notifies users of significant 'whale' movements between exchanges, wallets, and DeFi protocols, with transactions often exceeding tens or hundreds of millions of dollars. Beyond raw alerts, the platform offers on-chain analytics (e.g., realized profit tracking) and an aggregated crypto news feed. It operates a freemium model with a 7-day free trial and paid tiers, targeting active traders and analysts who monitor large-holder behavior as a market signal.

WhatsOnChain is a block explorer and analytics platform purpose-built for the BSV (Bitcoin SV) blockchain, with secondary support for BTC mainnet and testnet environments. The platform provides real-time visibility into blocks, transactions, mempool status, mining statistics, node status, and network fees, alongside tools for broadcasting and decoding raw transactions. It exposes a public REST API suite used by developers building on BSV, and supports a plugin ecosystem that allows third-party applications to integrate custom views and bookmarks. Primary users include BSV developers, node operators, researchers, and token issuers working with standards such as STAS tokens and 1Sat Ordinals.

WhiteMatrix is a blockchain developer services firm that provides tools and infrastructure for smart contract development and deployment across multiple blockchain networks. Its primary product, ChainIDE, is a cloud-based integrated development environment supporting Ethereum, Fisco BCOS, and CocosBcx, designed to eliminate the need for local environment configuration during smart contract development. The company offers additional products including ChainCastle, an educational platform for blockchain development; ChainMigration, tooling for on-chain data migration; ChainFormation, a service for consortium chain deployment; and ChainInfra, a multi-chain CRUD API for blockchain interaction. These offerings are designed to serve individual developers and enterprise clients requiring end-to-end blockchain development and deployment workflows. WhiteMatrix operates joint research laboratories with the Chinese Academy of Sciences and CUHK's Human-Cloud Systems Lab.

XRPSCAN is a block explorer and analytics platform purpose-built for the XRP Ledger, providing real-time visibility into ledger activity including transactions, wallet balances, token listings, AMM pools, and validator status. The platform surfaces granular on-chain data such as ledger intervals, transactions per second, total XRP burned, and account creation counts, making it a reference tool for both casual users and developers working on the XRP Ledger. It also maintains a validator registry aligned with the XRP Ledger Foundation's Unique Node List, giving network participants a way to monitor consensus health. XRPSCAN is used by XRP holders, developers, and researchers who need a dedicated explorer for the XRP Ledger ecosystem, comparable in function to Etherscan for Ethereum.

ZettaBlock is a unified data and AI platform that provides on-chain and off-chain blockchain data infrastructure to Web3 developers and enterprises. Its core product line includes decoded abstraction layer tables, prebuilt and customizable low-latency APIs, and SQL-to-production-API tooling that enables developers to query blockchain data and build data-driven applications. The platform serves blockchain ecosystems, DeFi protocols, NFT platforms, and institutional crypto products, with notable customers including Sui, Polygon, EigenLayer, and Crypto.com. ZettaBlock's data is also available via the Snowflake Marketplace, extending its reach to data teams operating across both Web2 and Web3 environments.
