Cryptocurrency Node API Access

Cryptocurrency nodes are infrastructure endpoints that let crypto projects read blocks, transactions, addresses, tokens and smart contracts. Settla provides API access to blockchain networks and helps teams use stable RPC endpoints without operating every node themselves.

Choose a network below and use a stable endpoint to read blockchain data, send signed transactions and monitor network state.

How crypto projects use blockchain nodes

Wallets use nodes for balances and transaction broadcast, exchanges for deposits and confirmations, DeFi products for contract calls, and indexers for sequential block processing.

RPC, WebSocket and gRPC access

RPC handles request-response calls to node methods, WebSocket provides persistent subscriptions, and gRPC is used for supported networks and backend integrations.

How nodes differ from a blockchain explorer

A Blockchain Explorer is a manual search interface, while a node API is designed for programmatic integration and automated blockchain data processing.

When a private node is needed

A private node is useful for high or critical load, special RPC methods, custom limits and workload isolation. For development and moderate traffic, a shared endpoint is often enough.

FAQ

What is a cryptocurrency node?

It is a network node that validates or serves blockchain data and exposes programmatic access for applications.

Why do projects need node API access?

To read blocks, transactions, addresses and smart contracts, and to send already signed transactions to the network.

How is RPC different from WebSocket?

RPC usually handles request-response calls, while WebSocket keeps a persistent connection for subscriptions and real-time events.

When is a private node needed?

When a project needs dedicated resources, special methods, controlled limits or isolated production traffic.
