Transaction monitoring that doesn't miss hops
Most indexers give you event logs. SQD gives you event logs, internal transactions, delegate calls, and state diffs, the full execution trace. When funds move through a mixer or a nested contract call, your monitoring sees every step.
Built for Compliance at scale
Complete execution traces
Every internal call, every delegate call, every CREATE opcode, not just the top-level transaction. When funds move through 4 intermediate contracts before reaching the destination, you see all 4 hops. Most indexers show you 1.
State diff reconstruction
See exactly which storage slots changed and their before/after values for every transaction. Reconstruct fund flows that bypass Transfer events entirely, direct storage mutations that event-only indexers are blind to.
Cross-chain fund tracking
225+ networks from a single API. When funds bridge from Ethereum to Arbitrum to Polygon, your monitoring follows the trail without maintaining separate integrations for each chain. The coverage grows as SQD adds networks, you don't touch your code.
Audit-ready event exports
Structured, timestamped, decoded event data that compliance officers can read and auditors can verify. Every field typed, every address resolved, every timestamp in UTC. Compatible with Chainalysis, Elliptic, and custom AML tooling via standard JSON output.
Event logs only tell you what contracts chose to emit. Traces tell you what actually happened.
A contract can transfer ETH via an internal CALL without emitting any event. A delegate call can mutate state in a proxy contract while the calling contract emits the log. State can change via direct storage writes that bypass the transfer event pattern entirely.
If your transaction monitoring only watches event logs, you're blind to these patterns, and so is your compliance reporting. SQD provides full execution traces (CALL, DELEGATECALL, STATICCALL, CREATE, SELFDESTRUCT) and state diffs (storage key, before value, after value) for every transaction.
When funds route through a mixer, a proxy contract, or a complex DeFi position, every hop is visible. No hidden movements, no gaps in the trail.
Independently benchmarked data integrity
Benchmarked by a top DeFi protocol running production traffic on Base, with both response-time and validation outcomes measured.
SQD returns 100% correct data. Mega RPC fails 1 in 14 requests. Edge Proxy fails 1 in 7.
Premium RPCs match our speed but fail 5–15% of requests. SQD delivers both, under 50ms at P90 with zero errors.
Data integrity here is cryptographically enforced, not hand-waved in marketing copy.
Compliance teams can't work with "mostly correct" data. SQD's 6-step cryptographic validation pipeline. Merkle-Patricia trie rebuild, bloom filter verification, receipt hash validation, state root verification, produces data that is independently verifiable against the chain itself.
