On-chain OTC · Robinhood Chain · USDG and any ERC-20
Trade with size without nuking the chart.
Post an order as a maker: choose what you give, name the exact amount you want back, and escrow the input in the contract. A taker pays the output in one transaction. No pool is touched, so no price impact and no slippage.

How a fill works
Alice wants 68,120 USDG for 412 NVDA. Bob has the USDG. The contract is the intermediary.
1 · Post
Alice locks 412 NVDA on the contract and sets the exact USDG she wants back. Optional counterparty whitelist. Optional expiry.
2 · List
Public orders appear on the book. Private orders exist on-chain but only the whitelisted address can fill them; a link makes them easy to find.
3 · Execute
Bob sends 68,120 USDG. The contract rejects anything partial. Both sides move in one transaction or nothing moves.
4 · Settle
1% comes off what each side receives, 2% in total. No pool was touched, so the NVDA chart did not move.
What the contract enforces
Exact orders
You set both sides. The contract never trades against a pool, so there is no price impact and no slippage.
Full fill only
One maker, one taker, one settlement. No leftover dust on the book.
Escrow
The maker's input sits on the contract from the moment the order is posted. Cancel returns 100%.
Private orders
Set a counterparty and no other address can fill. Share the link; the whitelist does the gating.
Optional expiry
60 seconds to 365 days. After expiry the maker reclaims the escrow, with no deadline on reclaiming.
2% fee
1% from the maker and 1% from the taker, each taken from what they receive.
Token safety
Tokens outside the SLIP list are flagged on the book and in the fill sheet, with the contract address in full.
Any pair
USDG against tokenized stocks, or any two ERC-20s on Robinhood Chain. Thin pools are exactly where blocks matter.
Fee split
2% total. 1% maker, 1% taker. Cancel any time for free.

What the pool would charge
The same sizes sold into the pool for NVDA, versus SLIP. Constant-product maths on indicative reserves, an illustration.
Impact is the gap between spot value and what the pool actually returns. Through SLIP the gap is zero because the price is set in the order.
FAQ
What is a block on SLIP?
An order with both sides fixed: an exact amount the maker gives and an exact amount they want back. A taker fills the whole thing in one transaction or not at all.
Why is there no slippage?
Because nothing is swapped against a pool. The price is whatever the maker wrote in the order. The book shows you how that compares to the pool price so you can judge the block.
What does "discount" or "premium" mean on the book?
The block price against the current pool price, from the taker's point of view. A discount means the taker gets a better price than the pool would give for that size.
Can someone fill half my order?
No. The contract rejects partial fills. Post two orders if you want two sizes.
What happens if nobody fills before expiry?
The order expires and your escrow stays yours. Reclaim it whenever you like; there is no deadline and no fee.
How do private orders work?
You set a counterparty address when you post. The order lives on-chain like any other, but only that address can fill it. The share link just points at it.
Which tokens can I trade?
USDG against tokenized stocks like NVDA or SPY, or any ERC-20 on Robinhood Chain. Tokens not on the SLIP list are flagged so you can check the contract before you fill.
