# Struct

Current product state as of 2026-09-17.

> Struct indexes onchain data and ships the data backend with customer teams. Coverage is request-only.

Struct ships custom backends for trading apps, analytics, agents, wallets, bots, backtests, and pipelines. Every protocol is scoped and shipped with the customer team. Self-serve plans for onchain indexing are not currently available.

## Coverage

- Coverage is request-only. Examples include Solana, Base, BNB Chain, Ethereum, Robinhood, plus protocols including Uniswap, Jupiter, Aerodrome, Raydium, PancakeSwap, Pump.fun, Meteora, Moonshot, Orca, Bonk.fun, Zora, LaunchLab, Virtuals, Boop, Heaven. These are engagements. Struct scopes the data with the customer team, then indexes, backfills, and delivers it.
- Network architectures for custom engagements: SVM and EVM, normalized behind one consistent schema.
- Data types include markets and events, tokens, trades, transfers, wallets, balances, positions, cost basis, realized PnL, order books, candlesticks, prices, and market lifecycle events.
- Historical coverage is backfilled from genesis for datasets in scope and delivered alongside live updates.
- Production indexing has a 10ms median latency. Alternative feeds in Struct's current benchmark range from approximately 1 to 5 seconds.
- Delivery surfaces include REST queries, WebSocket streams, filtered webhooks, the TypeScript SDK, MCP for AI agents, and managed database or warehouse delivery.
