When SIP-1 was announced, the narrative was institutional. Large trades. High-volume traders. Market-impact-free execution for positions worth hundreds of BTC. Fair enough. But it missed something: any trader on StandX can use Block Trade right now. And the decisions you need to make to use it well are simpler than they seem.

You publish a trading intent on-chain. Counterparties fill it. StandX validates the risk and settles. None of those steps touch the order book.

That has one direct consequence most people don't stop to think about: the market doesn't see your order. The price you traded doesn't affect the Mark Price, doesn't appear in the trade history, doesn't change the funding rate, doesn't trigger anyone's liquidation. Execution happens in parallel to the market — recorded on-chain, but invisible to the CLOB.

For traders used to CEXs, this feels strange. On Binance, every order you place is visible. Every trade you execute moves the price, even if minimally. The idea of operating without leaving a trace in the book is new.

On StandX's Block Trade, that's the default behavior.

The core point: Block Trade isn't an alternative way to access the order book. It's a separate execution layer that exists alongside the book — without interacting with it.

In Block Trade, the two roles have different powers and constraints. Understanding which role you're taking is the first step to using the mechanism well.

If you're the Maker, you create the block. You define the pair, size, direction, price, and execution mode. You also set the Taker Min Qty — the minimum size each counterparty needs to fill. That parameter is at least the total size divided by 25, or the platform minimum, whichever is greater. As Maker, you can cancel the block at any time while it isn't fully filled. You have full control until execution is complete.

If you're the Taker, you browse the available blocks, filter by what makes sense for your strategy, and decide to fill a portion or the minimum size defined by the Maker. Your ability to cancel depends on the mode the Maker chose — and that's one of the most important differences on the platform.

This is where most traders will go wrong if they don't understand the difference. It's not an interface preference — it's a choice about how you want to receive market exposure.

Flexible. Each counterparty that fills part of your block generates an immediate, independent settlement. You open a position progressively as counterparties arrive. That means you can start having exposure in minutes, even if the full block takes hours to fill.

For Takers in Flexible mode: you can't cancel after confirming. The match is immediate and settlement follows. If you're in, you're in.

How it looks in practice:

→ You create a block: Long 5 BTC at $95,000, Flexible.
→ Alice fills 2 BTC. Immediate settlement. You're Long 2 BTC.
→ Three hours later, Bob fills 3 BTC. You're Long 5 BTC.
→ You had exposure from the first fill — no waiting for the full block.

FullMatch. No settlement happens until the block is 100% filled. All counterparties commit first, then StandX processes each settlement individually. If the block doesn't fill before expiration, it closes with zero execution.

For Takers in FullMatch mode: you can cancel your participation while the block hasn't completed yet. Once the block hits 100%, cancellation is no longer possible.

How it looks in practice:

→ You create a block: Long 5 BTC at $95,000, FullMatch.
→ Alice fills 3 BTC. Bob fills 2 BTC. Block 100% matched.
→ StandX processes settlement for Alice and Bob. You open Long 5 BTC.
✗ If the block only reached 4 BTC before the deadline — it closes. Zero exposure.

How to decide: Flexible is for those who want to start building a position now and accept partial fills. FullMatch is for those who need the exact size or prefer not to enter at all. There's no better mode — there's the right mode for what you're trying to do.

This scenario is more common than it seems, especially in volatile markets. Understanding it correctly avoids confusion when it happens.

Between the moment a counterparty confirms participation in the block and the moment of settlement, available margin can change. Other positions may have consumed margin, the market may have moved the account close to liquidation, or risk validation may reject the negotiated price against the current Mark Price.

If settlement fails for a specific counterparty, that match is marked as Failed. No position is opened for that counterparty. The consumed size doesn't return to the block — it simply disappears. The other participants are unaffected.

How it looks in practice:

→ Block: Long 10 BTC, FullMatch.
→ Alice fills 6 BTC. Bob fills 4 BTC. Block 100% matched.
→ Alice's settlement passes. She opens Long 6 BTC.
✗ Bob's settlement fails — insufficient margin. Bob opens no position.
→ Bob's 4 BTC don't return to the block. Alice and you are unaffected.

This has a practical implication for FullMatch users: even if the block reaches 100%, you may end up with less than the total size if some settlement fails. The system guarantees each participant is processed individually — no one contaminates anyone else's result.

The launch narrative focused on institutional. But the mechanism itself has no minimum size restriction for the Maker. Any trader can create a block.

The value of Block Trade for a mid-sized trader isn't in absolute volume — it's in execution quality. If you're building a position in a pair with lower liquidity on the order book, putting it all in at once via CLOB will deteriorate your entry price. Block Trade eliminates that problem regardless of position size.

As a Taker, there's also an opportunity few traders notice: you can browse the available blocks and find counterparties for positions that make sense for your strategy — at a price fixed by the Maker, without competing with the order book. That's especially relevant during low-liquidity periods, when the CLOB spread is wider.

And there's one more element the docs mention: after creating a block, StandX encourages you to share it on X to attract counterparties. That makes Block Trade a liquidity discovery mechanism that works partly through the community — not just the platform's algorithm.

The insight that shifts the perspective: Block Trade isn't a product for a specific type of trader. It's an alternative execution layer any trader can use when the order book isn't the best option for what they need to do.

You don't need to wait for institutional volume. You don't need a massive position. You need to understand the mechanism and have a reason to use it.

To access: standx.com/perps/block-trade. The page shows available blocks with filters by pair, size, and mode. The most popular ones appear in the main banner.

To create your first block as Maker: define the pair, size, direction, price — Mark Price or Limit Price — and mode. Review the Taker Min Qty the system calculated automatically. Confirm, sign the transaction in your wallet, and your block is published on-chain.

To enter as Taker: browse the blocks, filter by what makes sense, check the minimum size required by the Maker, and confirm. In Flexible mode you can't cancel after. In FullMatch mode you can cancel until the block completes.

The order book is the default. Block Trade is the option when the default isn't enough.
