Polkadex Dedicated Nodes & RPC Infrastructure | OnFinality

Polkadex is a fully decentralized peer-to-peer orderbook-based cryptocurrency exchange built on Substrate. It combines the speed and liquidity of centralized exchanges with the self-custody and transparency of DeFi. Developers building trading bots, wallets, analytics tools, or DeFi products on Polkadex need reliable node infrastructure to read chain state, submit transactions, and monitor network activity.

What is Polkadex?

Polkadex is a non-custodial orderbook exchange that enables high-frequency trading, limit and market orders, and cross-chain asset transfers via the THEA bridge. It operates as a Polkadot parachain, leveraging Substrate's forkless upgrades and interoperability. The network is designed for both retail and institutional traders who require a decentralized environment without sacrificing performance.

Why Run a Polkadex Dedicated Node?

While public RPC endpoints are available for light testing, production applications demand dedicated infrastructure. A dedicated Polkadex node gives you:

• Full control over node configuration and sync mode (full, archive, or validator).
• Consistent performance with no rate limits or shared resource contention.
• Enhanced reliability through monitoring, automatic upgrades, and fallback options.
• Data retention – archive nodes store historical state, essential for analytics and backtesting.

Polkadex Node Types on OnFinality

OnFinality supports three node types for Polkadex:

• Full Node: Synchronizes the current chain state; suitable for most dApp backends and wallet services.
• Archive Node: Retains all historical state; required for block explorers, analytics, and applications that query past data.
• Validator Node: Participates in block production and consensus; for teams running their own validator on the Polkadex network.

All nodes are deployed on multi-cloud, globally distributed infrastructure with options for self-service or fully managed operations.
