Chainstack is a blockchain node platform that powers global Web3 applications across fintech, DeFi, wallets, custodians, gaming, AI agents, trading, and analytics.
Chainstack's core products include Global Node, low-latency RPC endpoints for everyday workloads; Dedicated Node, single-tenant nodes with guaranteed resources for heavy workloads; reliable infrastructure built for trading bots and MEV strategies; and Unlimited Node, an add-on for unmetered request scaling. Together with Chainstack Self-Hosted for teams that need infrastructure on their own premises, these products cover every stage from prototyping to institutional-scale deployment.
Chainstack supports major blockchain networks, including Ethereum, Solana, BNB Chain, Polygon, Hyperliquid, Arc, Robinhood Chain, and other EVM-based and non-EVM chains, with elastic (auto-scaling) and dedicated node instances across mainnet and testnet. For Solana-focused trading and MEV operators, Chainstack offers the Yellowstone gRPC Geyser plugin for real-time on-chain data streaming and Jito ShredStream for low-latency transaction propagation.
Deployment options span the public cloud, preferred service providers, or fully self-hosted infrastructure, all managed through a single console with standardized node management across chains and environments. Core infrastructure features include global load-balanced RPC endpoints, blockchain data APIs, node monitoring, and request-unit-based usage tracking, keeping performance predictable and costs transparent as usage grows.
Chainstack offers a free Developer plan alongside paid Growth, Pro, Business, and Enterprise plans, so teams can start building at no cost and scale into preferred infrastructure setup as usage grows.
Teams cut time-to-market, cost, and risk with a single platform for blockchain nodes, whether in the cloud, through a preferred service provider, or self-hosted. Standardized node management across chains and environments puts reliability on autopilot and keeps performance predictable.
Operators get control and transparency, while developers get a consistent way to build and scale. Fintech companies, DeFi protocols, wallets, custodians, trading firms, analytics platforms, and Web3 service providers running fleets use Chainstack as the fastest way to run reliable, predictable blockchain nodes at scale.

TProof
Create Decentralized Proof of Timestamp: Ethereum-based certifications for digital content existing prior a certain point in time.
TProof is studied to support any amount of certification, as it's primarily based on two mainstream platforms: Ethereum and Arweave. Ethereum is where the certification happens, storing the hash of your file at a given timestamp. That combination is represented in the form of an NFT, free to move and trade as you with. Arweave is where you can optionally upload your file, making it public (and eternal). This step is optional, and suits those use cases where you want not just the hash, but also the file to be visible all over the world.
Either you are a company, or a Web3 project that needs to generate a cryptographic proof around a digital content, you can integrate our Smart Contract.
