Clarity before
every transaction
Know What You Sign. Control What You Share. A free preview of what a Robinhood Chain transaction will do, before your wallet asks you to sign.
Onvex is not an exchange and makes nothing private. It reads the chain and explains; it never holds funds or keys, and a preview is a reading of the latest block, not a guarantee. Method and limits

To your wallet, the signature is the contract
Your wallet shows a hex string and a fee. Not the spender, not the allowance, not the least you will accept for a swap.
You approve one prompt. That prompt is the whole surface of what happens next. If it says more than you read, it still counts.
Most losses start in the part people read least: an approval with no limit, a swap that takes any price, a recipient one character off.
Checking every call by hand on an explorer does not scale, so most people sign and hope. Hope is not a check.
Every preview names where each fact came from: the simulation, the gas estimate, the quote and the price feed, each read on the latest block. Nothing is a guess dressed as a number.
An approval row shows the allowance read on chain today, not the amount in an old event. Removing one is a single transaction that you read first and sign yourself.
Tracking tells pending, confirmed, failed and replaced apart, and links each answer to the block or the nonce that shows it. A failed transaction still costs its fee; the page says so.
Transaction Preview
Paste a hash, paste a request, or build one here. Onvex names the function, the recipient, the value and the fee, runs the call on the latest block, and for a swap re-quotes it to show how far your minimum sits below the current price.

Approval Review
Every allowance your wallet has given, read as it stands today: which contract can spend, how much, and since which transaction. Spenders on our list are named with a source; the rest say so. Remove any of them from your own wallet in one transaction.

Transfer Tracking
Paste a hash and keep the tab open: pending, confirmed with its block and confirmation count, failed with the fee it still cost, or replaced when its nonce went to another transaction. Each answer links to the explorer page that shows it.

One path, in the open
You paste or build a request. Onvex decodes it and runs it against the latest block. You sign in your own wallet, or you do not. Nothing in between holds a key, holds funds or sends anything for you.
Anything you sign on Robinhood Chain: your address, the contract, the amounts, the call data, the fee and the time. Every preview lists exactly this before your wallet opens.
Only what you paste or connect: an address, a hash, a request. It is used to answer that one check. There is no account, no email and no tracking script.
Your tracked hashes and your last inputs live in this browser's local storage. Clear them any time; our server never had them.
Monitoring many wallets, advanced analytics and an API. No privacy network, no hidden routing, no zero-knowledge claims: none of that exists here.

A set of free checks for Robinhood Chain: a transaction preview before you sign, a review of the token approvals your wallet has given (with a revoke button), and tracking for a transaction until it is final. It reads public chain data and explains it.
No. Onvex does not trade, route, hold or move funds. When you swap, revoke or anchor a receipt, the transaction goes from your own wallet to the contract it names. The name of the domain is not a product claim.
No. Everything you sign on this chain is public: your address, the target, the amounts, the call data and the time. Onvex shows you that list before you sign; it hides nothing and uses no privacy network.
No. Paste any hash or address. Connecting fills in your address so the preview can check your balance and allowances, and lets you revoke an approval or send a transaction you built here.
No. It runs on the latest block. The next block can differ: prices move, allowances change, and a contract can behave differently for a different caller or time. The preview tells you what it read and when.
