Live on Robinhood Chain · not audited

Name any basket
of stocks. Trade it.

Round Lot lets anyone combine tokenized stocks into a single token — SPCX plus TSLA as ELON — mint it, and trade it anywhere. Every basket keeps redeeming even when the issuer freezes a component.

How it works

Two lines of code create a market.

The factory is permissionless. Pick any two or more tokenized stocks, name the result, set your fee, and deploy. You earn 70% of every mint fee on that basket, forever.

// anyone can run this — no permission, no listing process
factory.create(
    "Elon", "ELON",
    [SPCX, TSLA],   // any 2+ tokenized stocks
    30              // 0.30% mint fee, your choice, 1% ceiling
);

// ELON is now a plain ERC-20.
// Mint it with SPCX + TSLA. Redeem it back any time.
// Trade it on Uniswap, or quote a memecoin against it.

Redemption is always free and always in-kind — you get the underlying stocks back, never a price feed's opinion of them. Creating a basket bonds LOT, refundable at any time.

The problem

Single stock tokens make poor denominators.

Since mid-July 2026, launchpads have let creators denominate tokens in tokenized NVDA or TSLA. It worked — that one mechanic pushed Robinhood Chain past every Solana venue in tokenized-stock volume. A single stock token is still a bad unit of account.

01

Flow moves the denominator

Trade against one thin token and you move the token itself. The unit of account drifts for reasons unrelated to the company.

Stock tokens are ~4% of chain TVL. A GME-paired token cleared $15M against ~$30M on tokenized GME.

02

Single-name event risk

A market quoted in NVDA reprices on NVDA earnings. The creator inherits gap risk they never chose.

Tokenized AAPL: $1.78M cap. TSLA: $1.58M.

03

No anchor out of hours

A stock token's peg leans on onboarded market makers and an open equity market. For 135 hours a week it has neither.

Markets open 32.5 of 168 hours. Chain trading never stops.

Freeze resilience

Verified against a real issuer freeze.

Robinhood can pause any stock token, blocklist addresses, and claw back balances. So can every rival issuer — Backed can force-transfer from any address, Ondo has frozen tokens in production. This is a property of the asset class, not a defect.

So we tested it. On a mainnet fork, using the real privileged accounts against the real contracts:

ScenarioExecuted byResult
Component paused mid-flightreal TOKEN_PAUSER_ROLEHealthy components still paid; frozen leg became a claim; settled on unpause
Balance clawed back 10%real ADMIN_BURNER_ROLELoss shared evenly; nobody wiped out
Vault blocklistedreal BLOCKER_ROLERedemption refuses cleanly rather than burning shares; recovers on unblock

Why this matters

If NVDA is paused, every NVDA-quoted pool stops dead — the quote asset cannot move, so the market cannot function. A basket token has no pause of its own, so its pools keep trading while roughly one component's worth of backing is temporarily impaired. Round Lot converts a binary freeze into a fractional, temporary one.

101 tests. 128,000 randomised calls per invariant.

Fuzzing found two real bugs

A stateful invariant suite caught a flaw no amount of reading would have: a claim recorded while a component was frozen, followed by an issuer seizure, paid the first claimant in full and the last nothing — a bank run relocated into the claim ledger. Every claimant now takes the same proportional haircut regardless of order. A second review found that anyone could have seeded a freshly deployed basket before its creator, permanently fixing a worthless composition. Both are fixed, both have regression tests, and both fixes were verified present in the deployed bytecode.

Token

LOT — 1,000,000,000, fixed at deploy.

No mint function after construction. No owner, no pause, no upgrade path. The entire supply sits in a 2-of-2 treasury today: nothing leaves without both signers approving, and that has been exercised on mainnet.

Nothing below is in force yet

The plan that follows is a published intention, not an on-chain fact. No vesting schedule, no emissions programme and no airdrop exists today. Vesting and merkle-distributor contracts are written and tested but neither is deployed or funded. Every figure below is subject to change until the moment it is executed on-chain, at which point it becomes verifiable and permanent.

Planned distribution

2026 benchmarks assume 15–30% of supply goes to investors. Round Lot has no investors and has raised nothing, so that entire bucket is redirected to the people who actually use the protocol. Community-facing allocations total 57%.

Rewards target volume, not deposits

Almost every protocol emits tokens against total value locked. It is the wrong target twice over: TVL is trivially manufactured with your own capital, and the capital it attracts leaves the day emissions stop. Round Lot pays against swap volume routed through a basket while it serves as a quote asset.

TargetGameable bySurvives emissions ending?
TVLDepositing your own moneyNo — mercenary capital exits
Basket supplyMinting to yourselfNo
Quote-asset volumeOnly by paying real swap fees to real LPsYes — the pools already exist

Wash-trading to farm this costs the LP fee on every round trip, which flows to the very liquidity the protocol needs. The attack subsidises the thing it attacks.

Airdrop — weighted to what is expensive to fake

Anti-sybil filtering is the defining feature of 2026 airdrop design, and the industry standard is now a dual filter: exclude an address for being a sybil or for being a genuine low-effort farmer. Six months of ordinary use should outweigh six days of intensive farming.

Where LOT gets its bid

Two sinks, both scaling with real usage rather than narrative. Bonding: creating a basket locks 25,000 LOT, refundable, so demand tracks the number of baskets people actually maintain — this is live today. Fees: each basket charges a creator-set mint fee capped at 1%, split 70% creator and 30% protocol, with the protocol share flowing to the treasury and, once a market exists, to buy-and-burn. Redemption is never taxed; exit is a safety property.

Deliberately not shipped

No staking, no veLOT, no gauge voting. They are the obvious next additions and also where small teams disappear for six months. Bonding and fees first; governance only once there are enough baskets that directing emissions is a real problem.

The flagship is intentionally unseeded. Seeding fixes a basket's composition permanently, so it will be set with real capital at deliberate weights rather than in a test.
