fundly documentation

How funds, shares, NAV and fees work.

Basics

What is fundly?

fundly is an onchain fund platform on Robinhood Chain. Anyone can put together a fund from listed assets (stock tokens, crypto, USDG and pons ecosystem tokens), give it target weights and rules, and launch it from their own wallet. Anyone else can invest in it with USDG and receive fund shares.

There is no company holding your money. Every fund is its own smart contract that holds its assets directly. Deposits, withdrawals, fees and rule changes all happen onchain, where anyone can check them.

  • Creators design and run funds. They pick assets, weights, fees and deposit rules.
  • Investors deposit USDG, hold fund shares, and can cash out at any time while redemptions are open.
  • Everything shown in the app (funds, NAV, holders, activity) is read live from Robinhood Chain. Nothing is simulated.

Basics

Getting started

  1. 1Install an EVM wallet such as MetaMask, Rabby or Coinbase Wallet.
  2. 2Click Connect wallet. fundly will ask your wallet to add or switch to Robinhood Chain (chain 4663).
  3. 3Get a little ETH on Robinhood Chain to pay network fees.
  4. 4Get USDG on Robinhood Chain if you want to invest.
  5. 5Open Market to browse funds, or Create to launch your own.
fundly never asks for your seed phrase and never moves funds without a signature from your wallet. Each action shows up in your wallet for you to review before you sign.

Funds

How funds work

A fund is a basket with rules. When it is launched, the fundly factory deploys a new fund contract that stores:

  • Its name, symbol, description and creator (the manager).
  • The list of assets and their target weights, which must add up to exactly 100%. A fund can hold up to 20 assets.
  • A yearly management fee (max 5%) and a performance fee setting (max 30%).
  • A minimum investment, an optional capacity cap, and whether deposits and redemptions are open.

Only assets listed in the fundly asset registry can be used. Each registry entry records the token contract, its category, decimals and a USD price used for valuation.

Funds

Fund shares

Each fund issues its own share token (ERC-20, 18 decimals). Shares are your claim on a proportional slice of everything the fund holds.

  • Depositing mints new shares to your wallet.
  • Redeeming burns your shares and sends you your slice of the fund.
  • Shares sit in your wallet. They can be held, transferred or redeemed without asking the creator.

Investing

Depositing USDG

All deposits are made in Paxos USDG on Robinhood Chain (6 decimals). Investing takes two wallet signatures the first time:

  1. 1Approve: lets the fund contract move the amount of USDG you are depositing.
  2. 2Deposit: the fund pulls your USDG and mints shares to your wallet.
shares received = deposit value × shares outstanding ÷ NAV

For the very first deposit, 1 USD of value mints 1 share.

  • The app sends a minimum-shares limit with your deposit. If the price moves against you before it is confirmed, the transaction reverts instead of filling at a worse price.
  • A deposit fails if deposits are closed, it is below the fund's minimum, or it would push the fund over its capacity cap.
  • Deposited USDG stays in the fund as USDG until the manager rebalances into the target assets.

Investing

Redemptions

Redemptions are in-kind. You don't receive a single USDG payout. Instead, you receive your exact share of every token the fund holds.

Fund holdsYou redeem 10% of sharesYou receive
1,000 USDG10%100 USDG
2.0 WETH10%0.2 WETH
50 TSLA tokens10%5 TSLA tokens

Because nothing is sold on your behalf, redeeming causes no slippage and doesn't depend on market liquidity. You can then keep the tokens or swap them yourself.

A creator can pause redemptions. The fund page always shows whether they are open. Check this before you deposit.

Creating

Creating a fund

  1. 1Details: name, symbol, description, category and optional X handle.
  2. 2Assets: search the registry, add assets and set weights. You can't continue until the total is exactly 100%.
  3. 3Rules: rebalance frequency, management and performance fees, minimum investment, capacity, and deposit and redemption toggles. Unsafe settings show a warning.
  4. 4Review: check everything, then click Launch fund and sign one transaction from your wallet.

Once the transaction confirms, the new fund appears on the Market for everyone, and you become its manager.

Creating

Managing a fund

Only the manager's wallet can call manager actions:

ActionWhat it does
SettingsOpen or close deposits and redemptions, change minimum investment and capacity.
Set weightsChange target weights. New assets must be listed, weights must total 100%, and an asset can only be removed once its balance is zero.
RebalanceSwap one held asset for another through a registry-approved swap router, with a minimum-output limit.

The manager can never withdraw investors' assets directly. The only ways tokens leave a fund are investor redemptions and swaps through approved routers.

Creating

Rebalancing

Over time prices drift, and new deposits arrive as USDG, so live weights move away from targets. Rebalancing swaps assets to bring them back.

  • Swaps can only go through routers approved in the fundly registry.
  • Both tokens in a swap must already belong to the fund.
  • Every swap has a minimum output. If the result is worse, the whole transaction reverts.
  • Each rebalance is recorded onchain and shown in the fund's history and on the Activity page.
The rebalance frequency you pick is a stated policy for investors. The contract doesn't run it automatically, so the manager carries out each rebalance.

Fees

FeeWho sets itHow it works
Management feeCreator, max 5%/yrAccrues every second. It is paid by minting new shares to the manager, which slightly dilutes NAV per share.
Performance feeCreator, max 30%Stored and displayed. It is not charged in the current contract version.
Protocol fee—None. fundly takes no cut of deposits or redemptions.
Network feeRobinhood ChainPaid in ETH for each transaction you sign.
yearly fee shares ≈ shares outstanding × management fee %

Protocol

Asset registry and prices

The registry owner lists the tokens funds can use and posts each token's USD price. Categories: stock tokens, crypto, stablecoins, pons assets and other.

  • Prices are posted onchain by the registry owner. There isn't a public price feed on Robinhood Chain yet.
  • NAV, deposit share amounts and redemption values all use these posted prices.
  • Delisted assets can't be added to funds, but funds that already hold them can still redeem them.
Because prices are posted by hand, NAV can lag the market. Check an asset's price before making a large deposit.

fundly runs only on Robinhood Chain mainnet. Wallets on any other network are asked to switch before anything is signed.

Protocol

Risk

  • Market risk: funds can lose value. Stock tokens and crypto can be volatile, and past performance says nothing about future results.
  • Smart contract risk: the fundly contracts have not been independently audited. Bugs could lead to loss of funds, so start small.
  • Price risk: valuations use owner-posted prices that may lag the market.
  • Manager risk: a manager can pause deposits or redemptions and chooses when and how to rebalance.
  • Asset risk: each underlying token has its own issuer and rules, including any limits on who can hold stock tokens.
Nothing in fundly is investment advice. Read a fund's assets, rules and fees before you invest.
