Question 1

What does Dwellir do?

Accepted Answer

Dwellir is a specialized blockchain node infrastructure provider focused on the Polkadot and Substrate ecosystem. Unlike generalist node providers like Alchemy or QuickNode that serve primarily EVM chains, Dwellir specializes in Polkadot relay chain, Kusama, and the growing collection of Substrate-based parachains that make up the Polkadot ecosystem. This specialization means deeper technical expertise in Substrate node operation, better performance on Polkadot-specific RPC methods, and broader parachain coverage than generalist providers.

For Nigerian Web3 developers building on the Polkadot ecosystem — whether on the relay chain itself, on Kusama (Polkadot's canary network), or on specific parachains like Acala (DeFi), Moonbeam (EVM-compatible), Astar (multi-VM), or others — Dwellir provides the specialized infrastructure needed to connect applications to these chains reliably.

Polkadot's architecture differs fundamentally from Ethereum. Rather than a single monolithic blockchain, Polkadot consists of a relay chain coordinating security for many parallel chains (parachains), each with its own specific purpose and token economy. Building on this ecosystem requires connecting to specific parachain endpoints, and Dwellir maintains nodes for dozens of Polkadot parachains. Archive node access is available for queries requiring historical state data.

WebSocket connections are the standard method for Polkadot/Substrate JSON-RPC communication, and Dwellir's infrastructure provides WebSocket endpoints for all supported chains. The @polkadot/api JavaScript library and Python substrate-interface use these WebSocket connections for all smart contract interactions, extrinsic submission, and state queries.

For Nigerian developers who are specifically building in the Polkadot ecosystem, Dwellir is a focused provider worth evaluating. For those primarily building on EVM chains, the major EVM providers (Alchemy, QuickNode, Infura, Ankr) are more appropriate choices with broader EVM-specific tooling support.

Dwellir supports multiple EVM-compatible chains alongside Substrate-based networks, enabling cross-chain application development from a single infrastructure provider. For Nigerian Web3 developers building DApps that need to interact with multiple chains, using a single provider simplifies API key management, billing, and support relationships.

The free tier provides 500,000 requests per day — sufficient for active development, integration testing, and early-stage production deployments. Paid tiers scale to billions of requests per month for high-traffic DApps and institutional clients. Global load balancing across geographically distributed nodes ensures low latency for Nigerian users regardless of which specific server handles their request.

Nigerian blockchain developers benefit from Dwellir's technical support and documentation, which are more accessible than running and debugging bare validator nodes. For developers entering the Polkadot ecosystem from Ethereum backgrounds, Dwellir's unified interface reduces the learning curve of connecting to unfamiliar Substrate-based networks.

WebSocket endpoint support is essential for real-time DApp features — subscriptions to new block events, transaction status updates, and on-chain state changes. Dwellir's WebSocket connections are stable and managed, removing the operational complexity of maintaining persistent connection pools that would otherwise require custom infrastructure work from Nigerian development teams. Dwellir's transparent status page provides real-time and historical uptime information for each supported blockchain network, helping Nigerian developers monitor infrastructure health and plan maintenance windows. Reliable status communication reduces debugging time when connectivity issues occur.

Question 2

How much does Dwellir cost?

Accepted Answer

Dwellir is free to start, with paid tiers for higher usage (freemium). Free tier available. Paid plans for production. Polkadot/Substrate specialist.

Question 3

How do I authenticate with the Dwellir API?

Accepted Answer

API Key

Question 4

Is there a rate limit on Dwellir?

Accepted Answer

Varies by plan.

Question 5

Does Dwellir offer a sandbox or test mode?

Accepted Answer

No public sandbox is documented for Dwellir. Check the official docs for the recommended way to test integrations safely before going live.

Question 6

What is Dwellir best suited for?

Accepted Answer

Polkadot, Kusama, and Substrate blockchain developers needing specialized node infrastructure for Polkadot ecosystem chains.

Question 7

Is there anything else I should know before integrating Dwellir?

Accepted Answer

Dwellir specializes in Polkadot/Substrate ecosystem node infrastructure. Good for Nigerian developers building on Polkadot, Kusama, and parachains. Less relevant for EVM chain developers.
