ETH to KAS: Swap Ethereum to Native Kaspa, No KYC

Ethereum keeps balances in accounts. One 0x address holds ETH and every token, and each transaction pays gas in ETH. Kaspa is a proof-of-work chain built as a blockDAG, where blocks are produced far more often than on Bitcoin and several can be added side by side. Its coins sit in outputs, like Bitcoin's, and addresses carry a kaspa: prefix.

Nothing from the Ethereum side carries over. Your 0x address, your seed in MetaMask and your ERC-20 tokens have no meaning on Kaspa. You need a separate Kaspa wallet before you start, such as Kaspium on mobile or KasWare as a browser extension.

The swap itself moves value across that gap. ETH goes in on Ethereum, native KAS comes out on Kaspa, and there is no bridge or wrapped token in between. Kaspa confirms the payout in a few minutes, and Kaspa Explorer Mostra no seu endereço.

The deposit for this pair is ETH on Ethereum mainnet. Many people now hold ETH on layer-2 networks such as Arbitrum, Optimism or Base, and those balances sit at the same 0x address. A wallet will let you send layer-2 ETH to the deposit address without a warning, but it arrives on the wrong network and the swap cannot see it.

Check the network name in MetaMask or Rabby before you send. It should read Ethereum or Ethereum Mainnet. If your ETH is on a layer-2, withdraw it to mainnet first.

Ethereum confirms the deposit in about 2 to 5 minutes, and gas for it is paid in ETH on top of the amount. Leave a little in the wallet so the transaction can go through. Gas varies with how busy the network is; the Guia para reduzir as tarifas de gás covers timing your send.

A Kaspa address starts with kaspa: followed by a long string of lowercase letters and digits. Copy it from the receive screen of Kaspium or KasWare and paste it whole, prefix included. Do not type it by hand, and check the first and last few characters after pasting.

Two slips come up often. The first is pasting an Ethereum 0x address into the payout field, because it was the last thing on the clipboard. The second is a test-network address from a developer wallet, which starts with kaspatest: and cannot receive real KAS.

A fresh Kaspa wallet is fine as the destination; it does not need any KAS before the payout arrives. Kaspium and KasWare show the new balance once the network confirms it, and a quick look on Kaspa Explorer settles any doubt.

The table shows why one wallet cannot cover both sides. Every row is different: the address shape, the coin that pays fees and the explorer you check. Keep both apps open while you set up the swap, the Ethereum one for sending and the Kaspa one for the receive address. After the payout, a small part of your KAS covers Kaspa's own fees, so you need nothing else to move it on. That is the opposite of a token payout, where a second coin has to sit beside the balance before it can travel.

ETH is worth many thousands of KAS, so small price moves on either side change the figure noticeably. The exchange box gives the exact KAS amount after fees for the ETH you enter, quoted off aggregated liquidity from leading crypto markets. The reference rate nearby is the market price for 1 ETH in KAS before fees.

The rate floats until your Ethereum deposit confirms. After that, most swaps finish within minutes, and the KAS payout then needs a few minutes on Kaspa. The box also shows the minimum and maximum for this pair.

No account, email or ID is part of any of this. GhostSwap is a no-KYC crypto exchange: an address for the KAS, an address you send from and the ETH deposit are the whole process. To move back later, use KAS para ETH, or see every Kaspa pair on the Troca Kaspa Disputas de Comerciais.

The Ethereum address you give as the sender is where ETH returns if anything goes wrong. If a swap cannot be completed, the coins are refunded to the sender address you entered. Make it an address in your own MetaMask, Rabby or Ledger, on Ethereum mainnet.

Sending ETH directly from an exchange withdrawal is a common shortcut, and a poor one here. The withdrawal comes from a shared exchange wallet, and a refund to it may never be credited back to you. Withdraw to your own wallet first and send the deposit from there.

Every swap gets a status page under its swap ID. The deposit hash opens on Etherscan, the payout on Kaspa Explorer. When Etherscan already shows the ETH confirmed and that page has been still for a long while, email support@ghostswap.io with the swap ID and the Ethereum transaction hash. Do not send the ETH twice.
