Try Before Committing: Introducing the WisdomTree Connect Sandbox

WisdomTree Connect was built to make placing and executing orders in the digital funds simple. A new piece now completes that experience without putting a dollar on the line: a full sandbox environment for testing, building, and validating before going live.

What is the Sandbox?

The sandbox is a near-exact replica of production. It mirrors both the screens clients click through including the refreshed UI and the APIs developers build against. It carries the same digital funds offered in production and supports most of the same blockchains, so testing happens in conditions that match the real thing.

One detail worth getting right: this is not a mockup with fake balances. In the sandbox, clients transact using real testnet tokens, for example, Sepolia USDC or Sepolia PYUSD, to walk through buying and selling the funds. The mechanics are genuine and run on real on-chain rails. The only thing that's zero is the value. That keeps the experience faithful to production while carrying no financial risk. Clients who don't already have testnet tokens can request small amounts from WisdomTree and start right away.

It doesn't just look like production, it behaves like it

The same rules, timing, and pricing apply throughout:

• Cutoffs and settlement timing are identical. Each fund keeps its real cutoff and settlement window.
• Settlement cycles mirror production. Orders settle on the same schedule they would live.
• NAVs mirror production. The NAV shown in the sandbox matches the NAV shown in production.

Here's what that looks like in practice. A standard primary-market creation order for WTGXX, submitted before the 3:30 PM ET cutoff on a day the market is open, settles T+0 with settlement landing around 4:00 to 4:10 PM ET, exactly as it would in production. Every other fund behaves the same way at its own cutoff and settlement time.

The full production feature set is available too, including Instant Buy, Instant Sale, and on-receipt functionality. That makes it possible to test the exact workflows used in the live environment.

The problem it solves

Until now, the only way to experience Connect was in production. That meant completing full AML onboarding and then transacting with real money in the live environment. Even with low minimums, that's a meaningful hurdle for an institution still deciding whether the platform is the right fit. And for a developer at a partner firm, there was no way to build and validate an integration without doing so against live systems with real funds at stake.

The sandbox removes both barriers. Institutions can try before committing. Partners can build before going live.

Who it's for

Allocators and institutions evaluating the funds. The sandbox allows the complete buy and sell flows to be walked end to end in the UI, showing exactly how the platform behaves before any capital is committed or onboarding is completed.

Builders and integrators. Protocols, broker-dealers, and wealth and technology platforms can build and test integrations against the same APIs as production, confirm everything works, and de-risk the project before launch.

Access is provisioned by the WisdomTree team on request. There's no AML onboarding required to get in, no real money involved, and no rate limits, data resets, or usage constraints once testing is underway.

Where this fits

WisdomTree Connect launched as a platform for placing and executing orders in the digital funds. The goal for 2026 is to grow it into genuinely institutional-grade infrastructure. Its the kind of platform that helps regulated partners scale distribution and meets the expectations institutions bring to any integrated system.

That push rests on two pillars. The first is production-ready API documentation, already live at docs.wisdomtreeconnect.com. The second is the sandbox which is now live. Together, the two pillars turn the documentation from something to read into something to build and test against, and signal a platform that's mature, partner-friendly, and ready to be built on.
