01 · GETTING STARTED

Introduction

Currently selectedRobinhood Chain · Chain ID 4663

WETH pair

DYOR Fun is a permissionless multichain launchpad deployed independently on Robinhood Chain, Arc, Stable, X Layer, and HyperEVM. Every launch creates a fixed-supply ERC-20 and immediately places the complete supply into an official V3 pool on the selected chain. HyperEVM uses PRJX V3; the other networks use their configured Uniswap V3 deployments. There is no private bonding curve, later liquidity migration, or separate inside and outside market.

The pool exists from the launch transaction onward. Its V3 position NFT is transferred to the immutable DYOR Fun Vault on that chain and cannot be withdrawn through the protocol.

04 · USER GUIDE

Launch on Robinhood Chain

Connect a wallet.Switch to chain ID 4663 and keep enough ETH for the factory fee, optional initial buy, and network gas.
Upload an image.PNG, JPEG, WebP, or GIF up to 4.5 MB. Images are center-cropped and normalized to a square WebP.
Enter token details.Name and ticker go onchain. Description and links become public metadata.
Choose the creator wallet.The connected wallet is the default; advanced settings accept another EVM address.
Optionally buy initially.The initial buy executes against the newly created WETH pool in the launch transaction.
Review and sign.Your wallet submits the transaction. The API never receives your private key.
Wait for the RH Chain indexer.The token appears with its pool, progress, market cap, metadata, and trades.

05 · TRADING

Trade on Robinhood Chain

Each token page is connected directly to the official Uniswap V3 pool. Quotes come from the configured Quoter V2 and transactions go through the configured swap router.

Buy: native ETH is wrapped to WETH inside the router and exchanged for the token.
Sell: the token is approved, exchanged for WETH, and unwrapped back to native ETH.
Every official pool uses the 1% V3 fee tier (10000).
User-selected slippage sets the minimum output; the transaction reverts if it is not met.
Approvals and swaps are confirmed on chain ID 4663 before the interface reports success.

06 · GRADUATION

Robinhood Chain graduation progress

Graduation is a permanent indexed milestone. It does not migrate liquidity, change the token, unlock LP, or create another market. On Robinhood Chain, the starting model is single-sided WETH market and the target is 4.5 WETH.

progressBps = min(currentPoolWETHBalance / 4.5 WETH × 10,000, 10,000)

graduated = allTimeHighPoolWETHBalance >= 4.5 WETH

Before graduation, progress follows the current WETH balance. Once the indexed all-time high reaches the target, graduated remains true and progressBps remains 10000.

graduatedPermanent milestone status.

targetLiquidityEthTarget in pair-token base units.

07 · FEES

Fees and creator rewards

Every official pool uses the standard Uniswap V3 1% fee tier. Fees accrue in the locked position as users trade.

The interface verifies the connected wallet against the token creator before enabling a fee claim.
The Locker is permissionless onchain: anyone can trigger distribution, but callers cannot redirect recipients.
WETH-side fees are collected, unwrapped to ETH, and distributed to the configured recipients.
Token-side fees are collected and sent to the burn address.
Harvesting never unlocks or migrates the LP position.
The ecosystem treasury may periodically support standout CTO teams and high-quality IP projects.

08 · LIQUIDITY

Locked liquidity and token deployment

Each Factory mints a V3 position NFT using the complete launch supply and transfers it to that chain's immutable LP Vault. The Vault exposes fee collection only and has no NFT transfer, approval, owner, or upgrade function.

Robinhood tokensBeaconProxy ERC-20s. The shared Token Beacon is owner-upgradeable.

Arc, Stable, X Layer, and HyperEVM tokensDirect immutable ERC-20 contracts deployed with chain-specific CREATE2 salts. They do not use the legacy Beacon.

Factory and LockerOwner-authorized controls apply only where the selected deployment exposes them.

LP VaultImmutable and outside upgrade authority on each chain.

Permanent custody removes LP migration and conventional creator LP withdrawal, but it does not remove risks such as low demand, volatility, wallet concentration, implementation upgrades to upgradeable components, or unrelated third-party positions.

09 · LAUNCH RULES

Chain-specific token rules

Robinhood launch protectionApplies to current Robinhood launches

Three protected contract blocks, counting the launch block.
Ordinary same-block public buys are blocked.
The launch transaction's Creator Initial Buy is quantity-exempt.
A temporary 2% maximum wallet and per-origin block cap apply.
All restrictions expire automatically at restrictionEndBlock.

HyperEVM launch protectionApproximately 30 seconds

Every ordinary wallet is capped at 2% of the fixed 1B supply.
The creator and Creator Initial Buy are not exempt.
Sells to the official pool remain available.
The pool and Factory are exempt so launch liquidity can be created.
The wallet cap expires automatically at restrictionEndBlock.

Arc, Stable & X LayerNo launch restriction window

No maximum-wallet purchase rule.
No same-block purchase restriction.
No per-origin block cap.
No Creator Initial Buy exemption is needed.
New tokens are ordinary direct, immutable ERC-20 deployments.

10 · VERIFICATION

Verify an official launch

Names and tickers are not unique, and the same hexadecimal address can exist on different chains. Always verify both chain ID and token address.

Choose the expected chain: Robinhood 4663, Arc 5042, Stable 988, X Layer 196, or HyperEVM 999.
Call getLaunchedToken(token) on that chain's official Factory.
Confirm exists is true and compare the returned pool with the expected V3 pool.
Confirm the position ID is registered in that chain's official Locker.
Open the transaction and contracts in the matching chain explorer.

if (!(await factory.getLaunchedToken(token)).exists) throw new Error("Not an official launch on this chain")

11 · DEPLOYMENTS

Contracts on all chains

The deployments are independent. Direct immutable launches use chain-specific CREATE2 salts; configurable-pair chains also include the selected pair in the salt.

12A · INTEGRATIONS

GMGN, DeBot, and third-party integrations

Every token trades directly in its official 1% Uniswap V3 launch pool. Integrators must select configuration, pair token, decimals, API prefix, and explorer by chain ID.

Use the chain-pinned API base; never infer the chain from a token address alone.
Robinhood uses WETH/18 decimals, Arc uses USDC/6 decimals, Stable uses USDT0/6 decimals, and X Layer uses WOKB or one of 35 supported wrapped xStocks/18 decimals.
X Layer currently exposes 36 pair choices. Each curve starts at $3,000 equivalent and graduates at $9,000 equivalent using the fixed price returned by the config API.
X Layer stock-pair launches may require an ERC-20 approval returned by /launch/prepare. OKB trades route through verified USDT0 plus the pair-specific USDG or USDC bridge returned as routeVia.
Read progress.bps, progress.graduated, and trading.pairToken from the matching integration endpoint.
Arc, Stable, and X Layer report zero token launch restrictions.

13 · DATA

Separate indexers and databases

Robinhood, Arc, Stable, X Layer, and HyperEVM each use an independent persistent indexer worker and database.
Each worker discovers only its chain's Factory TokenLaunched logs and official pool Swap logs.
Multicall3 refreshes market cap and pool balances in block-consistent batches on the selected chain.
Launches, pair identity, metrics, trades, protocol state, global rollups, and cursors stay inside the selected chain's dataset.
Frontend reads never trigger historical chain scans.

14 · RELIABILITY

Errors, limits, and caching

API errors contain a stable code and readable message.
Lists use cursor pagination, SQL sorting, indexed columns, and maximum page sizes.
Read responses use CDN stale-while-revalidate caching.
The live trade panel pauses polling in hidden browser tabs.
Independent database leases prevent duplicate index advancement on each chain.
Images are size-limited and normalized before storage.
All v1 endpoints support browser CORS.
The API never retries wallet failures with a private key.

15 · SAFETY

Risks

Token risk

Anyone can create tokens. Listings are not endorsements.

Price risk

Thin liquidity can create extreme volatility.

Contract risk

Contracts may contain unknown defects.

Metadata risk

User links may be misleading.

Wallet risk

Check the selected chain and inspect every transaction.

Infrastructure risk

RPC, API, or index services may fail or lag.

16 · FAQ

Frequently asked questions

Does graduation move liquidity?

No. The original LP remains locked on its launch chain.

Can a token become ungraduated?

No. Graduation uses the indexed all-time-high pair balance: WETH on Robinhood, USDC on Arc, USDT0 on Stable, or the selected fixed-price pair asset on X Layer.

Are the APIs the same?

They expose the same resource model, but use different prefixes, chain IDs, contracts, pair units, indexers, and databases.

Can new direct-deployment token addresses collide systematically?

No. Arc, Stable, and X Layer use chain-specific CREATE2 salts; X Layer also includes the selected pair asset.

Is there a transfer tax?

No. Trading uses the standard 1% V3 pool fee.

Can creators withdraw LP?

No. Each official NFT stays in its chain's immutable Vault.

Can developers launch through the API?

Yes. Use the chain-specific API to prepare an unsigned transaction, then sign it with a wallet on the returned chain ID.
