Polkadot Assethub RPC Endpoint

Fast, flat-rate Polkadot Assethub RPC node provider — free tier, no KYC, HTTP & WebSocket.

Polkadot Asset Hub is a Substrate-based system parachain on Polkadot that specializes in issuing and managing fungible and non-fungible assets. It uses the relay chain's DOT as its native token and is secured by Polkadot's shared validator set. SwiftNodes provides Polkadot Asset Hub RPC across load-balanced nodes.

Network: Polkadot Assethub

About Polkadot Assethub

Asset Hub is a system parachain (formerly Statemint) built with the Polkadot SDK / Substrate. It hosts the Assets and Uniques/NFTs pallets for creating and transferring tokens, and supports paying transaction fees in certain non-DOT assets.

It does not run general smart contracts in its base role; it is purpose-built for asset management and benefits from low fees and the relay chain's pooled security via parachain validation.

Common Use Cases on Polkadot Assethub

Issuing fungible tokens
NFT creation and transfer
Stablecoin settlement (e.g. USDC, USDT)
Paying fees in non-DOT assets
Cross-chain asset transfers via XCM

Polkadot Assethub Ecosystem

Hosts natively issued assets including Circle's USDC and Tether's USDT on Polkadot, and serves as the asset layer for parachains across the Polkadot network.

Frequently Asked Questions: Polkadot Assethub

How is Polkadot Asset Hub queried?

Asset Hub uses the Substrate JSON-RPC interface (chain_, state_, author_, and assets-related methods) over HTTP and WebSocket; the relay chain is queried over its own Substrate JSON-RPC.

Does Polkadot Asset Hub have an EVM chain ID?

No. Asset Hub is a non-EVM Substrate parachain addressed through Substrate JSON-RPC and SS58 addresses; it does not use an EVM chain ID in its standard configuration.

What are the DOT token decimals?

DOT uses 10 decimals; the smallest unit is the planck, where 1 DOT = 10^10 planck. Asset Hub uses DOT as its native token.

Can I deploy general smart contracts on Asset Hub?

In its base role Asset Hub is specialized for asset issuance and management via the Assets and NFT pallets rather than general-purpose smart contracts.
