Grid trading bot for Robinhood Chain

What Robinhood Chain is

It is an Arbitrum Orbit rollup — an EVM chain of its own that settles back to Ethereum rather than being a fork with its own validator set. Practically, that means it behaves like any EVM chain your wallet already speaks: same addresses, same signatures, same tooling.

• Chain ID 4663 for mainnet, 46630 for the testnet.
• Gas is paid in ETH — but ETH that has been bridged onto the L2, not Ethereum mainnet ETH sitting in the same address on L1. This is the single most common reason a first transaction fails.
• Blocks are cheap and fast, which is the property that matters here and is covered in the next section.
• Transactions are readable on its Blockscout explorer, so every trade your vault makes is a public receipt you can check independently of our dashboard.

Why an L2 suits a grid specifically

A grid bot is not one big trade. It is a ladder of small ones: buy a step down, sell a step up, repeat, and collect the difference. The strategy only earns if the spread between two adjacent rungs is bigger than the cost of trading between them.

That makes per-trade cost the whole game. On Ethereum mainnet a grid tight enough to fire often is usually a grid whose profits go entirely to gas, which is why grid bots historically lived on centralised exchanges. An Orbit L2 changes that arithmetic: fees are low enough that a rung can be small and still be worth taking, while the chain still settles to Ethereum. How a grid actually behaves — including the market that breaks it — is worth reading before you fund one.

The second reason is that very little runs here yet. Robinhood Chain is young, and most automated trading tools are built for the chains they were built for years ago. If you hold assets on this chain, the realistic alternative to a vault like this one is watching the charts yourself.

How a vault works here

Creating a vault deploys a contract that your wallet owns. You deposit into it, and from then on two things are true, enforced by the deployed code rather than by our promises:

• Only the owner can withdraw. Not the keeper, not us. There is no admin path out of your vault.
• The keeper can only swap, through a pinned router. Its authority is to route a trade for you at a price the vault accepts — it cannot send your funds anywhere.
• Risk caps bound every trade — maximum size per trade, a daily ceiling, and a slippage limit. You can set them tighter than the defaults; nothing can set them looser. The safety rails in detail.

Trades route through Uniswap v3 on the chain, and grid vaults are denominated against USDG so your range is a plain dollar range. You pay a 0.20% platform fee on each executed trade and a one-time on-chain fee when the vault is created — the app reads that creation fee straight from the contract that charges it and shows you the live figure before you sign. There is no subscription, so a quiet month costs nothing.

Which tokens you can trade

Any token with a route, including the tokenised equities that live on this chain and tokens that launched last week. What changes between them is not permission but protection, and the vault picks the model automatically:

• Oracle-bound. Where a Chainlink price feed exists, the vault checks the swap against the feed and rejects a trade that disagrees with it. That is the stronger protection, and the honest caveat is that feed coverage on this chain is narrow today — assume the token you have in mind is on the other path unless it is a major.
• Permissive. With no feed, the vault prices from the DEX itself and compensates with tighter risk caps and a bounded band around your range. You are not refused the token; you are given a smaller blast radius, and you should size the position like the long-tail asset it is.

Grid, DCA, Accumulation and Glide (a TWAP that spreads one order over time) all run here. What each strategy does.

What to weigh before you start

The reasons to be careful, stated as plainly as the reasons to be interested:

• Liquidity is thinner than on an established L1 or a major exchange. A grid trading a shallow pool eats its own edge in slippage — the slippage cap protects you from the worst of it by refusing the trade, but a vault that keeps refusing trades is a vault in the wrong market.
• Oracle coverage is narrow here, as above. Most tokens run the permissive path.
• You need bridged ETH for gasbefore anything works, including the vault creation itself.
• Our contracts have not been through a published third-party audit. It is on the roadmap, and until it lands, treat the code as unaudited and start small.
• A grid loses money in a sustained trend on any chain and any platform. The chain changes the cost of trading, not the behaviour of the strategy.

Starting a vault on Robinhood Chain

1. Connect an EVM wallet and add the network — chain ID 4663. Wallet setup.
2. Bridge a little ETH for gas, and hold the token and quote you want to trade.
3. Pick the strategy, the pair, the range and the caps, then sign the creation transaction. Creating a vault.
4. The keeper takes over from there and trades your range until you pause or withdraw.
