Transaction stuck pending on Robinhood Chain? How to fix it

Robinhood Chain produces blocks roughly every 100 milliseconds. On a chain that fast, a transaction that has genuinely reached the sequencer is confirmed almost immediately. So when your wallet shows a spinner for minutes, the honest translation is usually not "the chain is slow", it is "this transaction never reached the chain at all", or occasionally "it landed and my wallet has not noticed". Both are fixable. Work through the causes below in order.

First, check whether it actually landed

Before changing anything, find out what the chain thinks happened. Open Blockscout, the chain's explorer at robinhoodchain.blockscout.com, and search for your wallet address. Look at the most recent transactions.

• If your transaction is there with a success status, it landed. Your wallet's display is stale. Reload the page or reopen the wallet and the spinner resolves itself.
• If a different transaction is there with the same nonce, your stuck transaction was replaced (for example by a speed-up or cancel) and will never confirm. That is normal and nothing is lost except the original attempt.
• If nothing new is there after a minute, the transaction never reached the chain. Keep reading.

One quirk worth knowing: Robinhood Chain has no public mempool, and pending transactions are not visible before inclusion. There is no explorer tab where a queued transaction sits and waits. On this chain a transaction is essentially either included or nowhere, which makes the explorer check unusually decisive.

Wrong network is the usual suspect

The most common cause of a permanently spinning transaction is that it was signed for, or sent to, a different network. If your wallet was connected to Ethereum mainnet or another chain when you confirmed, the transaction may be sitting in that chain's queue, priced for that chain's gas market, while you watch a Robinhood Chain interface that will never see it.

Check the network selector in your wallet. If it shows anything other than Robinhood Chain (chain ID 4663), that is your answer. Switch networks and look at the wallet's activity list for the other chain; the transaction is probably there. You can let it confirm or cancel it from there. If the chain is not in your wallet yet, the setup guide covers adding it in one click.

RPC hiccups

Your wallet does not talk to the chain directly; it talks to an RPC endpoint, and that endpoint can be briefly unreachable, rate-limited, or stale. When that happens, the wallet may show a pending transaction that was in fact never accepted by the sequencer.

The fixes are unexciting and effective:

1. Retry. Reject or dismiss the pending prompt, reload the site, and submit again.
2. Check that your wallet's RPC for chain 4663 is the official endpoint, rpc.mainnet.chain.robinhood.com. If you added the chain by hand long ago, a typo here explains everything.
3. If the official endpoint itself is having a moment, wait a minute or two and retry rather than mashing confirm. Repeated submissions during an outage are how people end up with three identical swaps when service resumes.

Nonce gaps from a cancelled transaction

Every transaction from your account carries a sequence number called a nonce, and the chain executes an account's transactions strictly in order: nonce 41 cannot confirm before nonce 40. This creates the most confusing stuck state: a gap.

Here is how it happens. You submit a transaction that never lands, perhaps during an RPC hiccup, or you use your wallet's cancel button and the cancellation itself never confirms. Your wallet, believing the old transaction is still in flight, signs your next transaction with the following nonce. The chain, which never saw the earlier nonce, now refuses to include the new one until the gap is filled. Every transaction you send afterwards stacks up behind it, and everything looks frozen.

The fix is to fill or reset the gap:

1. In your wallet's activity view, find the oldest pending transaction. That one holds the missing nonce.
2. Use the wallet's speed-up or cancel option on that specific transaction. Either resolves the gap, because both submit a fresh transaction at the missing nonce. Once it confirms, everything queued behind it flows through within seconds.
3. If the wallet's buttons do not work, send a zero-value transaction to your own address with the nonce set manually to the missing number (MetaMask allows this under advanced settings, as does Rabby). Same effect: gap filled, queue released.

What about gas set too low?

On most chains this is the first thing to check. On Robinhood Chain it is close to last, and that is worth understanding. Gas here is paid in ETH and is cheap: a measured Splitshot swap on July 15, 2026 cost about 135,568 gas at an effective price that worked out to well under two US cents. Wallets have little trouble estimating fees in a market like that, and the underpriced-transaction limbo familiar from Ethereum mainnet is rare.

Rare is not never. Fee levels move with chain load, so if you manually forced a very low gas price, or a wallet estimated during an unusual spike, a speed-up (resubmitting the same nonce with a higher fee) fixes it the same way it does anywhere. Just check the other causes first; on this chain they are far more likely.

The five-minute checklist

When a transaction looks stuck, run this in order:

1. Search your address on Blockscout. If the transaction is there, reload your wallet and you are done.
2. Confirm your wallet is on Robinhood Chain, chain ID 4663, and check other networks' activity if it is not.
3. Verify the RPC endpoint is rpc.mainnet.chain.robinhood.com, then reload and retry once.
4. Look for an old pending transaction holding a nonce gap, and speed it up or cancel it.
5. Only then consider fees: speed up the transaction with a higher gas price.

The good news underneath all of this: a stuck transaction has not taken your money. Until a transaction is included in a block, nothing has moved, and gas is only paid on execution. The spinner costs you patience, not funds. Diagnose calmly, fix the actual cause, and the queue clears in seconds.
