01Overview

Fluid Liquidity is one interface to everything that trades on Robinhood Chain: a registry of 330+ tokenized stocks, ETFs, treasuries, stablecoins, yield tokens and memecoins with live prices, a swap routed through 0x and LI.FI, a yield desk that enters real ERC-4626 vaults and yield-bearing tokens, managed ETH and USDG vaults, and a perps venue settled in ETH.

Swaps and Earn positions never leave your wallet. Vaults and perps use a treasury wallet so balances can be settled quickly; every deposit into it is verified on-chain before it is credited and every payout is a public transaction.

02Getting started

1. Add Robinhood Chain to your wallet: chain id 4663, currency ETH, explorer Blockscout. The app offers to add it when you connect.
2. Bridge ETH for gas and USDG or ETH to deploy through the official bridge.
3. Connect a wallet. Every installed wallet is listed by name; pick the one you want.
4. Open Assets, Swap, Earn, Vaults or Trade.

Fluid Liquidity never asks for seed phrases or private keys.

03Swap

The asset registry lists every Robinhood-issued stock and ETF token (ERC-20, 18 decimals), the majors bridged to Robinhood Chain, USDG and other stablecoins, yield-bearing tokens and every memecoin with a live DEX market. Prices come from LI.FI and DexScreener and refresh every 45 seconds.

A swap asks the 0x Swap API for a route and falls back to LI.FI. Your wallet signs the transaction directly. ERC-20 sells need a one-time approval to the aggregator. Stock tokens trade 24/7 at DEX prices, which can drift from the underlying market outside US hours.

04Earn

Earn lists venues that a wallet transaction genuinely enters. ERC-4626 vaults (Morpho Steakhouse USDG, Spark spUSDG) take an approve and a deposit and can be redeemed at any time. Yield-bearing tokens (Maple syrupUSDG, Ethena sUSDe, Midas MGLO) accrue yield in their price, so buying the token is the position.

Rates are fetched live from DefiLlama and the issuers. A venue with no public feed shows no number instead of a guess.

05Community pools

Anyone can fund a reward budget in any Robinhood Chain token and set a fixed APY and a lock between 30 and 365 days. Deposits are accepted for 7 days after funding, then every stake locks until the same unlock date.

The reward for a stake is fixed the moment it is admitted and deducted from the budget, so a pool can never owe more than it holds. Max total stake equals budget divided by (APY times lock years). After maturity stakers claim principal plus reward from the pool vault.

06Vaults

Managed vaults accept ETH or USDG. A deposit is a plain transfer to the treasury; once it has two confirmations it is credited to your position and starts earning the vault rate every second. Withdrawals pay accrued yield first, then principal, straight to your connected wallet.

Minimums are set per vault to keep gas proportional and shown on the vault before you deposit.

07Perps

Deposit ETH to a trading balance, then long or short memecoins (DexScreener priced), tokenized stocks (Chainlink feeds) and metals and energy (external feeds) with up to 5x. Positions are settled in ETH against the trading balance. Minimum size is 0.005 ETH.

Liquidation is at entry times (1 minus 1 over leverage) for longs and entry times (1 plus 1 over leverage) for shorts. A sweep runs every few seconds and closes positions past that price; the margin is lost.

Custom pairs list any DEX-traded token at 2x. The creator pays a 0.05 ETH listing fee and seeds at least 0.05 ETH of liquidity. Trader profits are capped at that liquidity and trader losses flow into it.

08Fees

• Swap. Aggregator route and network gas only.
• Earn. Whatever the underlying protocol charges. Nothing on top.
• Vaults. 10% performance fee on yield, taken at withdrawal. Never on principal. No deposit, withdrawal or management fee.
• Perps. No open, close or funding fee. Custom pair listing costs 0.05 ETH.

09Risk disclosure

You may lose some or all of what you deposit. In particular:

• Smart-contract risk. Vaults, aggregators and token contracts may contain bugs, even after audits.
• Issuer risk. Tokenized stocks depend on their issuer and the off-chain assets backing them.
• Treasury risk. Managed vaults and perps balances are liabilities of the treasury wallet, not on-chain positions you control.
• Market risk. Leverage magnifies losses. Liquidation forfeits the full margin.
• Pool risk. Community pool tokens may be illiquid or have owners with mint or pause rights. Check the contract on Blockscout.

Nothing in these docs is financial advice.

11FAQ

• What is Robinhood Chain? An Arbitrum-stack L2 (chain id 4663) where Robinhood issues tokenized US stocks and ETFs as ERC-20s. ETH is the gas token and USDG, the Paxos Global Dollar, is the native stablecoin.
• Do you hold my funds? Swaps and the Earn venues never leave your wallet: you approve, you sign, tokens land in your address. Vaults and perps use a treasury wallet so balances can be settled off-chain quickly; every deposit and payout is verified on-chain and visible on Blockscout.
• Where do the yields come from? Earn shows the live rate of each protocol, pulled from DefiLlama and the issuers themselves. Venues with no public feed show no number. Vault APYs are set per vault and published in the app before you deposit.
• What does trading cost? Swaps pay only the aggregator route and gas. Vaults charge a performance fee on yield, never on principal. Perps have no funding rate; positions past their liquidation price are closed by a sweep every few seconds.
• Can I list my own token? Yes, two ways. Create a community pool by funding a reward budget in your token with a fixed APY and lock. Or list a 2x perps pair by paying a small listing fee and seeding ETH liquidity that traders win from and lose into.
• What are the risks? Smart-contract risk on the venues, issuer risk on tokenized stocks, market risk on everything, and treasury risk on vaults and perps. Read the risk disclosure in the docs and never deposit more than you can afford to lose.
