Environments
Dimes Multiply runs two fully isolated environments: production and sandbox. Pick one per integration and point all your traffic (REST, WebSocket, API keys) at the same environment.
Multiply exposes two independent environments. Each has its own base URL, its own API keys, its own contract addresses, and its own data — they do not share state in any way.

Picking an environment
Building a new integration? Start in sandbox. Request a sandbox API key via the Telegram link on dimes.fi, then follow the Quickstart against
https://api-sandbox.dimes.fi/v1.Running an existing integration in production? Keep using
https://api.dimes.fi/v1with yourdm_live_skey_...key.
Keys are environment-scoped and not interchangeable. A dm_live_skey_... key is rejected by api-sandbox.dimes.fi, and a dm_sbx_skey_... key is rejected by api.dimes.fi.
Parity
Sandbox mirrors production on every REST endpoint, WebSocket event, response shape, error code, resolver/settlement behavior, rate limit, and auth rule. If it works in sandbox, it works in production. The only intentional differences are:
Separate vault contract at a different address.
Fake USDC and fake Polymarket CTF instead of the real tokens. Sandbox USDC is minted to your wallet on request by the Dimes team.
No SLA. Sandbox may be reset or paused for maintenance on short notice. Do not build production workloads or customer-facing demos on it.
Contract addresses
See Contract Addresses for the canonical list of production and sandbox vault, USDC, and CTF addresses with Polygonscan links.
