Your users don't care which chain their tokens are on — they want to see everything in one feed. SQD delivers full transaction history, token balances, and transfer events across 225+ networks in under 50ms.
Query the complete transaction history for any address across any supported chain. Internal transactions, token transfers, NFT movements, and contract interactions — all in a single response, even for wallets with thousands of transactions.
ERC-20 transfers, ERC-721 ownership changes, and ERC-1155 batch transfers indexed with real-time updates. Balances reflect the latest confirmed block, not a cached snapshot from 5 minutes ago.
Aggregate a wallet's positions across Ethereum, L2s, Solana, and 220+ other networks without writing per-chain aggregation logic. One API call returns the complete picture — your frontend just renders it.
Stream Transfer, Approval, and ApprovalForAll events for monitored addresses as they confirm on-chain. Build push notifications, approval revocation alerts, and suspicious activity detection without managing WebSocket connections.
Token launches, airdrops, and market crashes all produce the same pattern: every user opens their wallet simultaneously to check balances. Most data providers degrade under this load — response times climb from milliseconds to seconds, and error rates spike.
SQD's 2,800+ worker nodes across a decentralized network don't have a single bottleneck to saturate. The same architecture that indexes 2 petabytes of cross-chain data handles your traffic spikes without breaking a sweat. P50 stays at 27ms. P90 stays at 48.5ms. Error rate stays at 0%.
Stop stitching together 5 different providers for transactions, token balances, NFTs, approvals, and activity feeds. SQD covers the full data surface.
