List of Developer Tooling projects on The Open Network (2026)

WDK provides open-source libraries and modules for building self-custodial wallets supporting multiple blockchains. The modular architecture includes wallet modules for blockchain operations, protocol modules for DeFi integrations including swaps, bridges, and lending, and pre-built UI components for React Native. Built on Bare runtime, it supports Node.js and React Native environments, enabling deployment across mobile, desktop, embedded systems, and server applications.

MDK is an open-source developer framework that gives Bitcoin mining operators and developers unified control over mining infrastructure. It combines a backend software development kit with a modular worker and orchestration architecture that standardizes communication with miners, sensors, cooling, and electrical systems, alongside a user interface development kit for building dashboards. Developers use it to build monitoring dashboards, automated workflows, pool management tools, and analytics or optimization applications without building device-level integrations from scratch.

TON Virtual Machine is a stack-based execution environment for running smart contracts on The Open Network. It processes asynchronous messages and compiles contracts written in FunC, Tact, and Tolk into gas-optimized bytecode. The Acton CLI provides scaffolding, testing, debugging, deployment, and verification in a single binary.

TON Connect is a standardized authentication protocol for linking wallets to decentralized applications on TON. It establishes encrypted sessions between wallet providers and dApps through a unified protocol specification. Developers integrate browser-based and Telegram Mini App wallet connections through a single SDK.

TON AgentKit is a developer toolkit for building autonomous AI agents that transact on The Open Network. It provisions dedicated agentic wallets and exposes APIs for agents to send payments, interact with smart contracts, and manage assets programmatically. Agents operate at thousands of transactions per second without human intervention.

Crypto Exchange API is a developer API that enables platforms to add crypto swap functionality and expand supported coins and tokens, with partner revenue sharing and priority support.

Exchange Widget is an embeddable module that lets websites offer crypto swaps, buy/sell, and DEX modes with customizable appearance, token settings, and performance statistics.

Topper is a fiat-to-crypto on-ramp and crypto-to-fiat off-ramp delivered through an embeddable widget and developer APIs for business partners and wallets. Consumers buy crypto directly to a self-custodial wallet using cards, digital wallets, or bank transfers, and sell crypto to receive fiat on a linked debit card. The product supports recurring purchases and integrates via a web SDK, mobile SDK, REST API, webhooks, and single sign-on for partner applications.

MPC Node Suite is a fully privatized, white-label MPC-TSS infrastructure that enables businesses to build keyless wallet and custody systems at scale. Server-side middleware secured by Intel SGX trusted execution technology works alongside SDKs for web, iOS, and Android to provide distributed key generation, signing, refreshing, and recovery with configurable signing thresholds. The suite supports hierarchical deterministic key derivation and multiple blockchain networks, serving exchanges, payment service providers, wallet service providers, and self-custody service providers building cold-wallet and custody applications.

StaFi LSaaS is a developer toolkit that enables Layer 1 teams, project developers, and startups to deploy liquid staking protocols without building infrastructure from scratch. The stack provides modular smart contract frameworks for EVM and Cosmos environments, supporting both LST and LRT deployment. Builders configure staking pool logic, validator delegation, and token issuance through pre-built components maintained by the StaFi development team.

Tatum Platform is a unified blockchain development toolkit providing RPC nodes, APIs, SDKs, and developer tools for building Web3 applications. The system offers access to multiple blockchain protocols through standardized interfaces while maintaining cross-chain compatibility and enterprise-grade infrastructure.

Cross-chain infrastructure that enables secure wallet-to-app connectivity through decentralized service nodes, gateway nodes, and relay services using rendezvous hashing-based database architecture.

A unified API infrastructure providing read and write connectivity to multiple blockchains and DeFi protocols. The system supports transaction signing, data querying, price discovery, trade decoding, compliance checks, and liquidity management across DEXs, bridges, lending platforms, staking protocols, oracles, and NFT marketplaces. The platform uses a modular architecture enabling developers to interact with various chains and protocol endpoints through standardized API calls.

Drops Airdrop Tracker monitors wallet addresses across multiple blockchain networks to identify unclaimed cryptocurrency airdrops, providing eligibility checks and Telegram notifications. The platform tracks airdrops on Ethereum, Solana, Cosmos, Aptos, Sui, Starknet, Bitcoin, and TON without requiring wallet connections.

Validator Gateway is an infrastructure tool for blockchain validators that reduces latency between validator nodes and MEV relays. It connects validators to optimized network paths and integrates with MEV-Boost workflows, including a Proposer-MEV Protect feature that captures additional MEV value while applying compliance filters to incoming order flow. Validators use it to improve consensus and execution layer rewards through custom timing parameters and higher-quality block proposals.

Solana Trader API is a developer API that enables faster and more reliable transaction landing on Solana without requiring users to run their own node. It offers frontrunning protection, stake-weighted quality of service, and simultaneous submission across multiple channels, alongside real-time streaming of new pool and DEX activity. Trading bots, DeFi traders, NFT minters, wallets, and RPC providers use it to improve execution speed and reduce failed transactions.

Data Streams is a real-time data feed service that delivers blockchain activity including swaps, blocks, mempool transactions, and shred data with minimal delay. It runs on the same relay infrastructure as bloXroute's execution services, replacing lossy RPC polling with continuous, gap-free data delivery. Developers and trading systems use the feeds to build closed-loop trading and execution pipelines across multiple supported blockchains.

Transaction & Bundle Propagation is an execution service that submits single transactions or grouped bundles across multiple blockchains with optimized, low-latency propagation paths. It routes submissions through private, authenticated channels so that frontrunning and sandwich bots cannot intercept pending activity. Traders, searchers, and infrastructure teams use it to achieve faster and more reliable transaction landing than public relay or RPC alternatives.

The EVAA SDK is a TypeScript library for programmatic integration with the EVAA lending protocol on the TON blockchain. It exposes methods for querying pool state, user positions, and interest rate data, and for executing deposit, borrow, repay, and withdrawal operations. A Go language implementation is also available for alternative integration paths.

Cronos API provides developers with swap integration capabilities enabling token exchange functionality to be added to applications within 30 minutes through standardized endpoints handling RPC complexity and security.

Titan Trade Bot is a Telegram Mini App providing mobile-first token trading interface enabling users to execute swaps and discover new tokens directly within Telegram messenger with simplified navigation and optimal pricing.
