Question 1

How do you access Sui data with RPC and data providers?

Accepted Answer

Sui exposes a JSON-RPC interface for reading objects, transactions, checkpoints, and events, and you connect to it through a fullnode endpoint. The practical question is which endpoint to use: a public fullnode for exploration, a managed RPC API for production traffic, or a dedicated node when you need isolation and predictable capacity.

This reference walks through the Sui RPC surface, how to configure an endpoint, how to query data with curl and JavaScript, and how to decide between public, managed, and dedicated options. It also covers common failure modes and the operational checks that keep Sui data access stable as your app grows.

Question 2

Sui RPC on GitHub: Where to Find Endpoints, SDKs, and Node Configs

Accepted Answer

Developers searching for "sui rpc github" usually want one of three things: a working Sui RPC endpoint, the official Sui GitHub repositories that document JSON-RPC and the newer gRPC-based APIs, or example code that connects a client to a Sui full node. This article maps those needs to concrete resources and shows how to move from a public endpoint to infrastructure you can rely on in production.

You will find the Sui JSON-RPC method surface, a curl and TypeScript example, a comparison of public versus managed versus dedicated Sui RPC, and a debugging path for common connection and method errors. OnFinality provides Sui RPC API access and dedicated Sui nodes when you outgrow shared public endpoints.

Question 3

QuickNode Sui RPC: What to Compare Before You Migrate

Accepted Answer

If you are evaluating QuickNode for Sui RPC, the real question is whether a general-purpose multi-chain provider matches how Sui actually works. Sui uses its own JSON-RPC schema, object-centric data model, and transaction execution flow, so endpoint compatibility, method coverage, and archive behavior matter more than a familiar dashboard.

This page gives you a practical evaluation path: confirm the Sui endpoint you are testing, check the methods your app depends on, compare shared versus dedicated infrastructure, and decide whether to stay, migrate, or run a hybrid setup. OnFinality offers Sui RPC and dedicated node options alongside other supported networks when you need predictable access for production workloads.

Question 4

Sui Public RPC: What It Gives You and When to Move On

Accepted Answer

Sui public RPC endpoints are shared, unauthenticated JSON-RPC URLs that let you read chain state, submit transactions, and prototype against Sui mainnet or testnet without provisioning a node. They are the fastest way to get a wallet or script talking to Sui, but they are shared capacity with no account, no SLA, and no visibility into who else is using the same URL.

This page explains what a Sui public RPC endpoint can and cannot do, how to configure Sui JSON-RPC calls correctly, and the signals that tell you it is time to move to a managed RPC API or a dedicated Sui node. OnFinality provides Sui RPC through its RPC API and dedicated node offerings if you need isolated capacity and a support path.

Question 5

Sui JSON-RPC: Methods, Endpoints, and How to Use Them

Accepted Answer

Sui JSON-RPC is the standard interface for interacting with the Sui blockchain, enabling developers to query chain data, submit transactions, and subscribe to events. This article explains the core methods, how to connect to Sui endpoints, and common pitfalls to avoid when building on Sui.

Question 6

Sui Mainnet RPC: How to Connect and What to Check

Accepted Answer

Learn how to connect to Sui Mainnet RPC endpoints, understand the JSON-RPC methods, and evaluate infrastructure options for production apps. This guide covers chain settings, request examples, and key considerations for choosing between public and dedicated nodes.

Question 7

How to Set Up a Custom Sui RPC Endpoint for Your dApp

Accepted Answer

Learn how to configure a custom Sui RPC endpoint for your dApp, whether you're using the public endpoint, a managed provider like OnFinality, or your own node. This guide covers endpoint configuration, JSON-RPC examples, and common troubleshooting steps to keep your Sui application reliable.

Question 8

Sui API: How to Choose the Right Interface for Your dApp

Accepted Answer

Sui offers multiple API interfaces—JSON-RPC, gRPC, and GraphQL—each suited to different workloads. This guide explains the differences, helps you decide which interface to use, and shows how to connect to Sui mainnet and testnet with OnFinality's managed infrastructure.

Question 9

Sui gRPC Providers: Public, Managed & Dedicated RPC Compared

Accepted Answer

Sui gRPC providers give applications a typed, streaming path to Sui data, but access models differ significantly. Public Foundation gRPC endpoints can suit prototypes and low-volume tooling; evaluate their current limits, support, and production terms before depending on them. Managed gRPC providers operate shared endpoints with documented capacity, monitoring, and support, making them a practical default for dApps, indexers, and backend workers. Dedicated Sui gRPC nodes isolate your workload on private infrastructure and are justified when burst behavior, latency, or compliance requirements outgrow shared capacity. The evaluation should be gRPC-first: confirm LedgerService and StateService read support, TransactionExecutionService for ExecuteTransaction and SimulateTransaction, and SubscriptionService for SubscribeCheckpoints, SubscribeTransactions, and SubscribeEvents. Also verify rate limits, burst allowances, regions, failover, and incident communication before moving production traffic. OnFinality provides managed Sui gRPC and RPC infrastructure for mainnet and testnet, with a path to dedicated nodes when workloads need isolation. Start from /networks/sui to review current Sui network support.

Question 10

Sui Testnet RPC & gRPC: Endpoint, Faucet & Developer Setup

Accepted Answer

Sui Testnet RPC gives developers a gRPC-first path to query checkpoints, objects, and balances; simulate and execute transactions; and stream real-time activity using OnFinality managed endpoints. The modern workflow uses LedgerService for checkpoint data, StateService for object and balance reads, TransactionExecutionService for SimulateTransaction and ExecuteTransaction, and SubscriptionService for SubscribeCheckpoints, SubscribeTransactions, and SubscribeEvents. Legacy Full Node JSON-RPC remains useful for migration comparisons, but new testnet integrations should target gRPC and treat JSON-RPC as a legacy surface. Use the official faucet at https://faucet.sui.io for test SUI, and keep testnet credentials separate from mainnet. Configure endpoint placeholders such as GRPC_ENDPOINT and authorization headers in SDKs, wallets, and CI. Because testnet endpoints can reset and faucet limits change, always build your testnet environment to be disposable and avoid hard-coding object IDs or transaction digests. Testnet is not permanent: verify current faucet policy, expect resets, and validate the same workflows before moving to Sui mainnet. For operational guidance, see /rpc-assistant/sui-rpc-guide and /networks/sui-testnet.

Question 11

Dedicated Sui gRPC Nodes: Streaming, Capacity & Isolation

Accepted Answer

Dedicated Sui gRPC nodes give your team an isolated full-node environment for high-throughput Sui data access. Instead of sharing rate-limited public or multi-tenant endpoints, you operate a node sized for your indexers, backend services, and subscription consumers. The gRPC API uses Protocol Buffers over HTTP/2, which makes checkpoint, transaction, and event streams more efficient than polling JSON-RPC. Dedicated capacity helps when you need stable throughput for backfills, multiple concurrent stream consumers, or transaction submission and simulation without noisy neighbours. You still own the operational surface: sync lag, disk growth, upgrades, and monitoring. The Sui gRPC surface includes LedgerService, StateService, TransactionExecutionService, and SubscriptionService. Streaming workflows such as SubscribeCheckpoints, SubscribeTransactions, and SubscribeEvents are central to low-latency indexing; ExecuteTransaction and SimulateTransaction support write and simulation paths. A dedicated node is not a managed magic box. Plan for state growth, snapshot recovery, TLS, load testing, and failover before production. This guide covers capacity planning, isolation, replay, monitoring, and full-node lifecycle decisions without vendor rankings or invented performance claims.

Question 12

Sui gRPC Guide: Endpoints, Streaming & JSON-RPC Migration

Accepted Answer

Sui gRPC is the type-safe, Protocol Buffers-based RPC interface exposed by Sui full nodes. It is the recommended production path for reading chain state, executing transactions, and consuming real-time streams. OnFinality provides managed Sui gRPC and RPC infrastructure on mainnet and testnet; the current endpoint details are published on /networks/sui. In practice, you use grpcurl with a GRPC_ENDPOINT placeholder and authorization metadata from your provider, then target services by name. LedgerService covers checkpoints and consensus data, StateService covers object reads and balances, TransactionExecutionService provides ExecuteTransaction and SimulateTransaction workflows, and SubscriptionService offers SubscribeCheckpoints, SubscribeTransactions, and SubscribeEvents for streaming. Because JSON-RPC is being retired, teams should plan a migration by mapping legacy read, write, and subscription workflows to these gRPC services. Work from generated clients or proto definitions, not hand-built JSON calls. Test on testnet with the faucet at https://faucet.sui.io, keep mainnet separate, and verify stream reconnection and field masks before production.
