10 exchange WebSocket feeds aggregated to one normalized table. Reconnect logic that survives a 30-second silent drop.
From multi-exchange feed aggregation to on-chain analytics to custody integrations, we ship systems that handle 24/7 markets without coddling. Reconnection logic and deduplication are table stakes.
WHY
We've connected to 10+ crypto exchanges via REST and WebSocket, built funding rate ingest pipelines processing 50M+ events per day, and shipped market data infrastructure that survives the volatility spikes that kill underprepared systems. Reconnection logic, deduplication, and sequence validation are not optional.
On-chain data is messy at scale. Node sync lag, reorgs, mempool inconsistency. We built ingestion pipelines that handle Ethereum, Solana, and EVM-compatible chains with idempotent writes, block-level integrity checks, and automatic gap detection. The analytical layer sits on clean data, not raw RPC chaos.
DeFi protocols and custody systems demand cryptographic correctness and near-zero tolerance for operational bugs. Every system we ship in this space gets formal key management documentation, replay attack analysis, and transaction simulation coverage before it touches mainnet.

FEED RELIABILITY
Exchange-feed reliability matrix
Each exchange WebSocket has its own failure mode. We map them per venue and ship matching reconnect and gap-recovery logic. Snapshot plus diff replay, sequence number tracking, and silent-drop detection at 30 seconds. Heartbeat-only feeds get a synthetic liveness check on top of the exchange-provided ping. Aggregate uptime across the production stack stays at 99.9%+ measured end to end, not just from the exchange side.
| Venue | Reconnect cadence | Sequence-gap handling |
|---|---|---|
| Binance | Silent-drop 30s, snapshot every 6h | U-id continuity check, REST snapshot replay on gap |
| OKX | Ping every 20s, reconnect on missed pong | Sequence ID monotonic check, channel-level resync |
| Coinbase | Heartbeat channel, 10s timeout | Sequence per product, REST level-2 snapshot replay |
| Kraken | Ping every 30s, exponential backoff reconnect | Checksum field per book, full resub on mismatch |
| Bybit + others | Per-venue heartbeat, 15s detection | Snapshot + diff with sequence anchor, gap alert at 3s |
