02 / How it works

Four steps, then it runs itself

No onboarding, no approval queue, no waiting list. The slowest part is your wallet confirming a transaction.

01

Connect

Any EVM wallet, straight onto Robinhood Chain. No sign-up, no KYC, no email. Your address is the account.

02

Fund

Bridge ETH or USDG in, or swap into them here. Deposits are ordinary on-chain transactions, credited once they confirm.

03

Fill

Pick a vault, a yield venue, a pool or a market. Yield accrues by the second and positions mark to live prices.

04

Withdraw

Principal plus everything it earned, back to your wallet whenever you want. No lockups on vaults, no queues, no notice period.

04 / Why us

Why put money through Filler

The short version: the yield is real, the fees only touch what you made, and every movement has a transaction hash you can open.

+

Real yield, traced to source

Staking rewards, lending interest and liquidity fees earned on-chain. Nothing is paid out of emissions or out of the next deposit.

+

Every movement on the ledger

Deposits, payouts and settlements are ordinary Robinhood Chain transactions. Every one has a hash you can open on Blockscout.

+

Fees only on what you made

A performance fee on earned yield. No deposit fee, no withdrawal fee, no management fee on your principal.

+

One balance, four products

The same wallet earns, swaps, trades and stakes. No sub-accounts to fund and no transfers between products.

+

Solvency checked before the stake

Community pools take a reward budget up front. A stake is admitted only if its promised reward still fits inside it, under a row lock.

+

Custody stays with you

Swaps are signed by your wallet and never touch our treasury. Only the vault and trading balances are custodial, both withdrawable on demand.

Read the docs
What is Filler?

Four things on one chain: yield vaults for ETH and USDG, a swap across every tokenized asset on Robinhood Chain, leveraged perps settled in ETH, and staking pools anyone can open for their own token. One wallet, one balance, no sub-accounts.

Do I need an account?

No. Connect an EVM wallet and you are in. There is no sign-up, no email and no KYC. Your wallet address is the account, and disconnecting it is how you log out.

Where does the yield actually come from?

Staking rewards on the chain's native asset, lending interest on stablecoins, and fees from the on-chain venues we route to (Morpho, Spark, Maple, Ethena). Rates are read live from those venues. Nothing is paid from token emissions or from other people's deposits.

Are there lockups or withdrawal queues?

Not on the vaults. Principal and accrued yield can be withdrawn to your wallet at any time. Community pools are different by design: a pool has a subscription window and a fixed unlock date, both shown before you stake.

What are the fees?

A performance fee on earned yield only. No deposit, withdrawal or management fee on principal. Trading pairs charge a listing fee to the creator, not to traders. Exact numbers are in the docs.

Is Filler custodial?

Partly, and it is marked wherever it applies. Swaps are non-custodial: your wallet signs and the tokens go straight to it. The vault balances and the trading balance are custodial, held in the protocol treasury, and withdrawable on demand.

Which assets can I deposit?

ETH and USDG, the Paxos-issued Global Dollar native to Robinhood Chain. Bridge in from Ethereum or Arbitrum, or swap into them here. Tokenized equity vaults are next.

What are the risks?

Smart-contract risk, strategy risk, issuer risk on tokenized assets, and liquidation risk on any leveraged position. Leverage can take your whole margin. Read the risk disclosure in the docs before you deposit anything you cannot afford to lose.
