Deepstate UI — unofficial interface
An independent, non-custodial interface for the Deepstate onchain order book on Robinhood Chain.
What this is
This website is an unofficial third-party interface to the Deepstate protocol — a fully onchain central limit order book deployed on Robinhood Chain. It is operated independently, is not affiliated with Deep State Incorporated, and does not choose the listings shown on the official app. Deepstate's own interface and documentation live at deepstate.sh and docs.deepstate.
The matching engine is permissionless and non-upgradeable: any interface (including this one) can trade the same pools. We do not custody funds; every order, fill, and settlement happens directly onchain between your wallet and the Deepstate router.
How it works
Deepstate stores bids and asks in radix-tree order books and matches them with price-time priority. Order placement, matching, custody, and settlement are all onchain — there is no offchain matching or operator that can front-run or reorder your orders.
Every pool is derived deterministically from two token addresses (poolId = keccak(token0, token1)). Pools are permissionless: the first order in a new pair initializes its book. Pairs without liquidity simply show an empty book.
- SWAP (market) — fill-or-kill against the best opposing liquidity. Fails with a revert if there is no counterparty at the time of execution.
- LIMIT — rests on the book until filled by a counterparty or cancelled. Partial fills keep the remainder resting.
- Cancel / Claim — withdraws a resting order and collects maker proceeds (and any accrued rewards) in the same transaction.
Engine semantics we account for in this interface: order quantities are always denominated in the pool's token0 (deterministic address order), conversions apply a 0.5% safety margin so collateral never exceeds your input, and approvals are requested for exactly your input amount before the first trade per token.
Markets
The interface currently lists 12 hardcoded pairs:
Any other ERC-20 pair can be added through the pair selector's Custom token input — standard ERC-20s without fee-on-transfer only. The first order in such a pool creates it onchain.
Rewards
Only the NVDA/USDG pool has an attached DEEP reward hook (1B DEEP prefunded, split between the best bid and the best ask). Orders resting in any other pool do not accrue rewards. Maker rewards are claimed through the Cancel / Claim flow.
Fees
- Protocol fee — 10 bps charged by the Deepstate router on every fill, sent to the STATE vault.
- Interface fee — 5 bps (0.05%) charged by this unofficial interface for orders placed through it, paid onchain via
fillWithIntegratorFee. You can avoid it entirely by trading directly against the router from any other interface.

Terms of use
Unofficial interface. This site is an independent third-party interface to the Deepstate onchain order-book protocol. It is not operated by, affiliated with, or endorsed by Deep State Incorporated. Protocol contracts are used as deployed; this interface cannot pause, upgrade, or move protocol funds.
Fees. Orders placed here pay the protocol fee (currently 10 bps, set by the protocol) plus an interface fee of up to 5 bps shown on the order form and in the footer. The interface fee funds independent development and operation of this site only.
Restricted regions — tokenized equities. Tokenized equity pairs (e.g. NVDA and any pair flagged as a stock token) are not offered to US persons on this interface. Access from the United States to those pairs is blocked to the extent a client-side check can determine location; a determined user can bypass any client-side check (VPN), so this gate keeps honest users compliant but is not a security boundary. Real enforcement would require a hosted gateway, which this static interface deliberately does not operate.
Operator disclosure. This interface is operated independently by 0x4663. An affiliated market-making bot may provide liquidity on the same venues; matching is fully on-chain and neutral — the interface never prefers its own orders.
No warranty; your responsibility. Trading carries risk of loss. Tokenized assets carry issuer, custody, and redemption risk. Nothing here is financial advice. By trading you confirm you are eligible in your jurisdiction.
Disclaimer
Unaudited. The Deepstate protocol is experimental and has not been audited. This unofficial interface is likewise not audited and is provided "as is" without warranty of any kind, express or implied.
Trading onchain order books carries risk of loss, including partial fills, price slippage, unavailable liquidity, and protocol or token failure. Tokenized assets carry issuer, custody, and redemption risk independent of the technology. Nothing on this site is financial advice. Do your own research and only risk funds you can afford to lose.
