What you actually get

ETH to COINX, at four sizes

The payout network fee is a fixed amount, so the smaller the swap, the more of it that fee eats — which is why this table exists instead of one headline rate.

The two sides

Ethereum (Optimism) and Coinbase tokenized stock (xStock): what you send, what you receive

You send: Ethereum (Optimism)

Ether is the native asset of Ethereum, the smart-contract network that hosts most tokens and DeFi applications. It pays the gas fee of every transaction on that network, including transfers of ERC20 tokens. More about Ethereum.

On this pair it moves over Optimism — an address there starts with 0x — 42 characters.

ETH also exists on other networks — different addresses, not interchangeable: Arbitrum, BEP20, Base, ERC20, Linea, Manta.

You receive: Coinbase tokenized stock (xStock)

On this pair it moves over Solana — an address there 32 to 44 characters, no 0x prefix.

COINX lives on a single network here, so there is no wrong-chain version of it to confuse it with.

FAQ

ETH to COINX, in short

Using it

What is the minimum ETH to COINX swap?

0.0003689 ETH right now. The desk sets it live and it moves with the Solana network fee — below it, that fee would eat the swap. There is no fixed maximum on this pair.

Which address do I need to receive COINX?

A Solana address you control — it 32 to 44 characters, no 0x prefix. COINX exists on several networks; an address from another one looks valid and the coins would be unrecoverable, so we check it against Solana before creating anything.

How long does ETH to COINX take?

Around 10-60 minutes end to end, as forecast by the desk right now. Most of that is Optimism confirming your deposit — the exchange and the payout themselves take seconds.

Money & privacy

Can I get a guaranteed amount of COINX?

Not on this pair: it is floating only, because one of the two sides cannot be quoted firm. The amount is set when your deposit confirms.

What does it cost?

Two things come out: the Solana network fee for sending your payout — 0.0014691 COINX right now — shown on its own line, and our margin, which is already inside the rate. Nothing is added after you confirm.

Do I need an account or ID?

No. There is no account to create and we never ask for identity documents, at any amount. The one case where a swap can be held is spelled out in the AML policy rather than hidden.

Is a ETH to COINX swap traceable?

On-chain, yes: Optimism and Solana are public ledgers, so the deposit and the payout are visible to anyone, like any other transaction on them. What nobody can link them to is an identity: there is no account, no document and no request log here — the privacy policy names the only parties in the path.

What if the swap cannot complete?

Every order takes an optional refund address, and it is worth filling in. If the exchange cannot go through — a deposit under the minimum, a pair that stops being quoted, or the one documented case of a flagged deposit where the law allows a return — the deposit goes back to that address, minus what the network charges to send it; we charge nothing for a refund. Without a refund address, a return has to be arranged by hand through support. The order page tells you which situation you are in; nothing is decided silently.
