Robinhood Chain

What Robinhood Chain actually is

Robinhood Chain is a layer-2 network built on the Arbitrum Orbit stack. Transactions are ordered by a sequencer and settled to Ethereum, which is what makes fees small and confirmation fast. For anyone building or trading on it, the practical consequences are the four below — and each one changes how a token launch behaves.

Does Robinhood Chain have a DEX?

Yes — and it is a familiar one. Tokens launched through Pons trade in standard Uniswap V3 pools, paired against WETH at the 1% fee tier. There is no bespoke exchange protocol to integrate against: swaps go through a standard SwapRouter02, and quotes come from a standard QuoterV2. Anything you already know about Uniswap V3 — tick ranges, exact-input swaps, price impact against pool depth — applies unchanged.

That matters more than it sounds. A launchpad that invents its own trading venue forces every tool, bot and analytics dashboard to be rewritten for it. Pons does not: once your token is live, it is an ordinary V3 pool that ordinary tooling can read and trade.

Which launchpads run on Robinhood Chain?

Pons

Pons is the dominant launchpad on the chain, running roughly four times the launch activity of the alternative. Its factory deploys the token and creates a locked Uniswap V3 pool in a single transaction, with an optional creator buy executed inside that same call. Liquidity is held by a locker contract, and creator fees accrue there to be claimed later.

Pons also enforces a launch-restriction window: for a configured number of blocks after launch there are per-wallet and per-transaction caps, and in the launch block itself only the creator’s own buy can execute. That window is the chain’s built-in anti-snipe mechanism — see sniper bots and anti-snipe protection for what it does and does not stop.

Bags

Bags is the other launchpad. Rather than opening a pool immediately, it starts a token on a bonding curve which later graduates into a pool. Different trade-offs: smoother early price discovery, but your token is not a standard AMM pool from block zero.

Why there is no public mempool — and what that changes

On Ethereum, a transaction is broadcast to a peer-to-peer network before it is mined, and anyone can watch that queue. That public queue is what makes classic front-running possible: a bot sees your pending “enable trading” transaction, pays more gas, and gets in front of it.

Robinhood Chain has no such queue. Transactions go to the sequencer and appear once they are already ordered. There is nothing to watch and nothing to outbid, so the classic mempool sandwich does not apply.

This is not the same as being safe from snipers. Bots can still watch confirmed blocks and the sequencer feed and buy in the very next block after a launch. What the chain removes is the ability to get in before you; it does not remove the race to be second. That distinction is the whole reason bundling still matters here.

What this means for launching a token

On Ethereum you would solve the launch race with a Flashbots bundle — hand a sealed group of transactions to a block builder and have them included together. That infrastructure does not exist on Robinhood Chain, so atomicity has to be built into the transaction itself.

There are two workable shapes, and BundleZeus uses both depending on the launch:

1. Buy inside the launch call. The Pons factory accepts a creator buy as part of launchToken. That buy executes in the launch block, where the restriction window blocks everyone else — so it is uncontested by construction.
2. One router multicall. SwapRouter02 exposes a multicall that executes many swaps inside a single transaction, each paying out to a different wallet. All of them land together or the whole call reverts, so nothing can be inserted between the buys.

Both are explained step by step in how to launch a token on Robinhood Chain. For what actually launches here in practice, see Robinhood Chain memecoins.

Network details: RPC, chain IDs, explorer and faucet

The values below are what you need to add the network to a wallet or point a client at it. Mainnet and testnet are separate chains — the testnet is where you rehearse.

Two things worth knowing before you build against these. The public RPC can trail the chain head by several blocks, so anything latency-sensitive should read from more than one source. And the explorer is Blockscout rather than an Etherscan instance, which matters if you are scripting against its API — the endpoints and response shapes differ.

For mainnet funds, see how to bridge ETH to Robinhood Chain.

Practical details worth knowing

• Gas estimation is unreliable. Orbit chains frequently mis-estimate eth_estimateGas for complex calls; production tooling should carry a sensible manual fallback rather than trusting the estimate.
• block.number lies, usefully. Inside a contract it returns the L1 block estimate, which advances roughly every 12 seconds — not the much faster L2 block. Any contract logic counting “blocks since launch” is really counting L1 blocks, which makes restriction windows far longer in wall-clock time than they look.
• The public RPC lags. Reads from the official endpoint can trail the head by several blocks, so anything latency-sensitive should read from more than one source.
• Bridging. ETH reaches the chain through the canonical bridge, or through third-party routes when you would rather not wait for the canonical withdrawal period.

Frequently asked questions

Launch on Robinhood Chain

BundleZeus is a token-launch bundler built specifically for this chain: it launches your token through Pons and fills up to 250 of your own buyer wallets atomically, so your buys land together instead of one at a time. You can rehearse the entire flow free on the testnet before spending anything on mainnet.
