Simulated chains, test keys, and replayable scenarios with identical request and response shapes to production, so integration work carries over one-to-one.
Deterministic EVM-style test networks with controllable finality, reorgs, and contract states.
Dry-run any transaction against any policy profile via POST /v1/simulate without creating records.
Prebuilt scenario packs: velocity spikes, sanctioned counterparties, anomalous flows, so you can see every verdict type fire.
Isolated workspaces with their own API keys, policies, and webhook endpoints.
Inspect signed sandbox records and verify signatures and Merkle proofs exactly as in production.
Nothing in the sandbox touches real assets or networks. Ever.
Design partners get full sandbox access and a direct line to engineering.
