Discover and Inspect Soroban Smart Contracts
LumenQuery indexes Soroban smart contracts on the Stellar public network and decodes their on-chain activity into structured, human-readable data. You can look up any contract by its ID to review invocation history, inspect function parameters and return values, browse persistent and temporary storage entries, and monitor emitted events. Every contract call is decoded from raw XDR, so you see function names, typed arguments, gas consumption, and transaction results without needing to parse binary data yourself. Use the explorer to audit contract behavior, track DeFi protocol activity, debug failed transactions, or build monitoring workflows around production contracts.

Soroban Contract Use Cases
Track Invocations
Monitor how often a contract is called, by whom, and with what parameters. Understand adoption trends and usage patterns across your deployed contracts.
Monitor Events
Subscribe to real-time contract event streams via SSE. Receive decoded events as they are confirmed on-chain without polling the network.
Audit Activity
Review the complete invocation history for any contract. Inspect decoded function calls, gas consumption, error codes, and transaction results.
Build Dashboards
Use the REST API to feed contract data into custom dashboards, monitoring tools, or alerting pipelines. Export data as CSV or JSON.
Analyze DeFi and Token Usage
Track how DeFi protocols, token contracts, and AMMs behave on-chain. Monitor liquidity pool interactions, swap volumes, and fee patterns.
Debug Interactions
When transactions fail, inspect decoded error codes, gas limits, and operation sequences to identify the root cause without replaying locally.
Watch Production Health
Monitor your deployed contracts for error spikes, gas anomalies, or unexpected call patterns. Detect issues before they affect your users.
AI Contract Explanations
We are building AI-powered explanations for Soroban contract calls. When available, you will be able to select any contract invocation and receive a plain-English summary of what it did, including parameter breakdowns, gas analysis, security observations, and pattern comparisons across multiple calls.
Explanations will be generated on demand and cached for 7 days. Usage limits will vary by subscription tier: 50 explanations per month on Developer, 500 on Team, and unlimited on Auditor and Enterprise plans. This feature is not yet enabled in the explorer.
Sample Contract API Response
The contract API returns structured JSON with decoded contract metadata, activity counts, and status information. Here is an example response from the contract detail endpoint.

Frequently Asked Questions
What is a Soroban smart contract explorer?
A Soroban smart contract explorer is a tool that lets you search for, inspect, and monitor smart contracts deployed on the Stellar network. LumenQuery decodes raw XDR data into human-readable formats, showing you function calls, parameters, return values, storage state, and emitted events for any contract ID on the public Stellar network.
Can I monitor contract activity in real time?
Yes. LumenQuery provides real-time event streaming via Server-Sent Events (SSE) for any Soroban contract. You can subscribe to a contract ID and receive decoded events as they are confirmed on-chain, without polling. This is available on Team tier and above.
Does LumenQuery support Soroban RPC methods?
Yes. LumenQuery provides managed Soroban RPC access at rpc.lumenquery.io. You can call standard Soroban RPC methods like simulateTransaction, getTransaction, getEvents, and getLedgerEntries without running your own node. The contract explorer uses these methods under the hood to fetch and decode contract data.
Can I search for a contract by its ID?
Yes. Enter any Soroban contract ID (starting with C) into the search bar on the contracts page. LumenQuery will fetch the contract metadata, recent invocations, storage entries, and event history. You can also search by deployer account or contract name if indexed.
Are AI explanations available for contract calls?
AI-powered contract call explanations are coming soon. When available, you will be able to get plain-English summaries of what a contract invocation did, including parameter breakdowns, gas analysis, security observations, and comparisons across multiple calls. Explanations will be cached for 7 days.
Can I export contract data as CSV or JSON?
Yes. LumenQuery supports exporting call history, event logs, and storage snapshots in both CSV and JSON formats. Export is available on Developer tier and above. You can also access all contract data programmatically via the REST API for integration with your own tools and pipelines.
