Chapter 1
Getting started
Fundr has four surfaces. Discover shows real assets and launches read live from Robinhood Chain. Create is the four-step wizard for designing and launching your own fund. Funds lists every fund recorded in the Fundr registry. Portfolio and Activity reflect your connected wallet and verified onchain events only.
Nothing in Fundr is simulated. If a value cannot be read from a contract or a chain event, the app shows an empty state instead of a number.
1 · Connect
Connect an EVM wallet and switch it to Robinhood Chain.
2 · Compose
Add real assets by contract address and weight them to 100%.
3 · Set rules
Fees, minimum deposit and rebalance cadence.
4 · Launch
Review the live protocol terms, sign, and get explorer links.
Chapter 2
Robinhood Chain
Robinhood Chain is an EVM network with chain ID 4663 and native currency ETH (18 decimals). Fundr talks to it over JSON-RPC and links every record to the public explorer.
Chain ID
4663
RPC endpoint
https://rpc.mainnet.chain.robinhood.com
Explorer
https://robin.etherscan.io
Reads are batched and rate-limit aware. If the public node throttles us, Fundr keeps the last verified data and labels it, rather than blanking the page or showing a fake zero.
Chapter 3
Wallet & network
Connect any injected EVM wallet from the top bar, then switch it to Robinhood Chain (chain ID 4663). Fundr reads balances, launch permissions and fees directly from the network — you are asked to sign only when you launch.
If your wallet is on another network, launch controls stay disabled and Fundr tells you exactly why rather than failing mid-transaction.
Balances shown in the wizard are real ERC-20 balanceOf reads using each token's own decimals(). Fundr never assumes 18 decimals.
Chapter 4
Funds & allocations
Identity
Name, ticker, short description and a category. The ticker becomes your fund token symbol onchain.
Allocation
Add real assets and weight them. The total must equal exactly 100% before you can continue.
Rules
Management fee, performance fee, minimum deposit and rebalance cadence are stored with the fund record.
Each allocation entry stores the chain ID, the real token contract address, symbol, name, decimals, its pair token and where it came from — a PONS V2 launch, a Robinhood stock token, a quote asset, or native ETH.

}Chapter 5
PONS V2 assets
PONS V2 is the launch protocol on Robinhood Chain. Each launch creates a token plus a bonding curve, recorded by the factory and emitted as a TokenLaunched event.
In the wizard you paste a PONS token address and Fundr reads its name, ticker, logo, description, supply, phase and curve state straight from the contracts. Tickers alone are never stored — an allocation always holds the real contract address.
Graduation progress is measured, not guessed:
progress = realQuoteReserve / graduationThreshold × 100
(clamped to 0–100%)
0 · NotGraduated
Bonding curve
Buys and sells happen against the curve. Progress climbs as the real quote reserve grows.
1 · Swept
Graduating
The threshold was reached and reserves were swept out of the curve.
2 · PoolCreated
Graduated
A live pool exists and the token trades on it.
3 · Rescued
Rescued
The launch was unwound by the protocol. Rare, and shown as-is.
Deployed PONS V2 contracts
Chapter 6
Stock tokens
The stocks tab lists Robinhood Stock Tokens deployed on Robinhood Chain. Fundr reads them from Robinhood's official stock-token service and keeps only assets that are active and have a deployment on chain ID 4663.
Each row carries the token's real contract address, symbol, name, decimals and ISIN, with a direct explorer link. Adding one to a fund stores the contract address, exactly like a PONS asset.
Fundr does not display stock prices, market caps or returns anywhere in the builder — those are not part of what it verifies.
Chapter 7
Launching a fund
Step 4 loads the live launch terms from the protocol before you sign: the launch fee, curve supply, graduation threshold, maximum creator tax and whether your wallet is allowed to launch (canLaunch). Nothing about those terms is hardcoded in the app.
Sign
Your wallet sends a payable launch transaction carrying the live launch fee.
Confirm
Fundr waits for the receipt and decodes the TokenLaunched event for your token and curve.
Record
The fund, its allocation and rules are saved to the Fundr registry and appear on Funds.
If the transaction reverts or is rejected, Fundr says so plainly. A launch is never reported as successful without a confirmed receipt.
Chapter 8
Data & verification
Every figure in Fundr comes from a chain event or a contract read. Launch events are indexed into a cache so pages load fast, but the chain stays the source of truth and each record links to the explorer so you can check it yourself.
Prices derived from a bonding curve are labelled as curve-derived. Fundr never displays a market price, APY, or historical return it cannot prove.

Glossary
Bonding curve
The contract that prices a PONS token before graduation. Each launch has its own curve address.
Graduation threshold
The quote-asset amount a curve must collect before it can graduate to a pool.
Pair token
The quote asset a launch trades against. 0x000…000 means native ETH; anything else is a real ERC-20.
Creator tax
Basis points routed to the launch creator on curve trades. Capped by the factory's maxCreatorTaxBps.
Allocation weight
Your fund's percentage for one asset. Weights are stored with the asset's contract address, never a ticker.
Curve-derived price
Quote reserve divided by token reserve. It is not a market price and Fundr labels it that way.

Common questions
Does Fundr custody my assets?
No. Fundr never holds keys. Every action that changes state is a transaction you sign in your own wallet.
Why is a value blank instead of zero?
Unknown is not zero. If a read fails or a field was never set onchain, Fundr leaves it blank rather than inventing a number.
Can I edit a fund after launch?
The fund token and curve are immutable once launched. Fund metadata and allocation records live in the Fundr registry and can be extended over time.
Why is my launch button disabled?
The wizard lists the exact reason: wallet disconnected, wrong network, allocation not at 100%, missing ticker, or the protocol reporting your wallet cannot launch right now.
Ready to launch in public?
Design your strategy, weight real onchain assets, and ship it from your own wallet.
