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, API keys, contract addresses, and data — they share no state.

Comparison

Aspect	Production	Sandbox
Purpose	Live positions with real pUSD	Integration testing with test pUSD and fake outcome tokens
REST base URL	https://api.dimes.fi/v1	https://api-sandbox.dimes.fi/v1
WebSocket URL	wss://api.dimes.fi/v1/ws/prediction-markets/positions	wss://api-sandbox.dimes.fi/v1/ws/prediction-markets/positions
Swagger UI	https://api.dimes.fi/v1/customer-docs	https://api-sandbox.dimes.fi/v1/customer-docs
API key prefix	dm_live_skey_...	dm_sbx_skey_...
Resource IDs	dm_pos_..., dm_off_..., dm_mkt_...	dm_pos_sdx_..., dm_off_sdx_..., dm_mkt_sdx_...
Chain	Polygon mainnet	Polygon mainnet
pUSD	Real pUSD	Test pUSD (minted on request to your wallet by the Dimes team)
Outcome tokens	Real Polymarket CTF	Fake CTF
Vault contract	Production LeveragedPredictionVaultV1	Separate sandbox LeveragedPredictionVaultV1 (different address)
Market data	Live Polymarket markets	Live Polymarket markets (read-only)
Funds at risk	Yes	No

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/v1 with your dm_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.

REST API

# Production
curl https://api.dimes.fi/v1/prediction-markets/markets \
  -H "Authorization: Bearer <jwt>"

# Sandbox
curl https://api-sandbox.dimes.fi/v1/prediction-markets/markets \
  -H "Authorization: Bearer <jwt>"

SDK

Parity

Sandbox mirrors production on every REST endpoint, WebSocket event, response shape, error code, resolver/settlement behavior, rate limit, and auth rule. The only intentional differences:

• Separate vault contract at a different address.

• Test pUSD and fake Polymarket CTF instead of the real tokens. Test pUSD is minted to your wallet on request by the Dimes team.

• No SLA. Sandbox may be reset or paused for maintenance on short notice.

Contract addresses
