Home / Developers / Sandbox

A sandbox that behaves like production.

Simulated chains, test keys, and replayable scenarios with identical request and response shapes to production, so integration work carries over one-to-one.

What you get

Everything needed to integrate before go-live

Simulated chains

Deterministic EVM-style test networks with controllable finality, reorgs, and contract states.

Transaction simulator

Dry-run any transaction against any policy profile via POST /v1/simulate without creating records.

Replayable risk scenarios

Prebuilt scenario packs: velocity spikes, sanctioned counterparties, anomalous flows, so you can see every verdict type fire.

Test keys & workspaces

Isolated workspaces with their own API keys, policies, and webhook endpoints.

Verification Explorer

Inspect signed sandbox records and verify signatures and Merkle proofs exactly as in production.

Zero real funds

Nothing in the sandbox touches real assets or networks. Ever.
