Stream fast, reliable, and autonomous on-chain data with the Portal — a decentralized retrieval layer designed for high-performance indexing. 225+ networks, zero egress, one endpoint.
Independently benchmarked by a top DeFi protocol running production traffic on Base. Error rates, median latency, tail latency, and consistency — all measured.
Mega RPC fails 1 in 14 requests. Edge Proxy fails 1 in 7. SQD: zero.
Other providers are fast on average but 9-10x slower under load. SQD stays under 50ms at P90.
SQD degrades 1.8x from median to P90. Others degrade 9-10x — that's the difference between consistent and unreliable.
Not just fast — deep. Traces, state diffs, zero egress, 225+ networks through one endpoint.
Download all you want. No surprise bandwidth bills. No metering on data out.
One API for every chain. One line on your invoice. EVM and Solana through the same interface.
Deep execution traces for debugging, analytics, and forensic investigation. Not an add-on — included by default.
Storage-level changes for every block. See exactly what changed in contract state, not just what was called.
Genesis to head in one API call. No separate providers for historical vs. real-time data.
The entire stack is open-source Rust (AGPL-3.0). Run the same code on your infrastructure anytime.

Portal streams data from a decentralized network of worker nodes. Each response is cryptographically signed and validated before delivery.
Direct HTTP streaming API for maximum flexibility. Build custom integrations in any language.
API Reference →High-level TypeScript SDK with batch processing, type-safe decoders, and database integrations.
Learn about SDK →Run your own Portal infrastructure. Same open-source code, your hardware, your rules.
Self-host Guide →Private Portal gives you the raw validated data. Need more? Subsquid Labs builds custom pipelines, integrations, and analytics layers on top.
Decoded transfer events across all ERC-20, ERC-721, and native tokens. Wallet balance tracking, transaction history, and activity classification.
Custom compliance pipelines integrating on-chain data with partner KYC/AML feeds. Flagging, risk scoring, and regulatory reporting on immutable source data.
Decoded events from major DeFi protocols — positions, liquidations, swaps, yields. Partner data integration for TVL, risk, and protocol benchmarking.
Transaction reconciliation against immutable Parquet records. Cost basis calculations, PnL tracking, and journal-ready data exports.
Custom alert pipelines for suspicious transfers, anomalous patterns, and compromised wallets. Failed transaction analysis reveals attack attempts others miss.
Data delivery to Snowflake, BigQuery, Kafka, S3, or your warehouse of choice. Cross-chain aggregation, custom transforms, and partner data enrichment.
Stream Solana data at full speed through the same Portal API. Instructions, token balances, account state — all accessible with the same developer experience.
