How to convert Ethereum to OKX Wrapped BTC

The widget above is already set to ETH on Ethereum → xBTC on Solana. The whole swap runs in one flow through NEAR Intents:

Step 1: Choose how to pay
Connect any EVM wallet such as MetaMask or Rabby that holds your ETH. Or turn on Swap from external wallet to get a deposit address and QR code you can pay from any wallet or exchange; you then add an address on Ethereum for refunds.

Step 2: Enter the amount and where to receive
Type how much ETH to swap and the Solana address that receives the xBTC, from a Solana wallet such as Phantom or Solflare. The widget shows how much xBTC you will receive, fees included, before you confirm.

Step 3: Confirm and send
Approve the transfer in your wallet, or send the amount to the deposit address. Once it confirms on Ethereum, solvers fill the swap and the xBTC is sent to your address on Solana. If the swap can't be filled, your ETH is refunded.

Prefer to keep a balance inside NEAR Intents? The Deposit tab adds ETH to it, Swap trades within it, and Withdraw sends tokens out to their own networks.

⚠ Important: receive on an address you control. If you send the xBTC to an exchange instead, check that it accepts xBTC on Solana: some exchanges don't credit deposits that come from a smart contract.

About the ETH → xBTC swap

This is a cross-chain swap: your ETH leaves Ethereum and xBTC arrives on Solana. Normally that takes a bridge plus a DEX, or a centralized exchange account. With NEAR Intents the deposit, swap and withdrawal happen in one flow, and what lands in your wallet is xBTC on Solana, ready to use there with no second bridging step.

xBTC is a tokenized version of another asset, so its price tracks its underlying rather than ETH. Swapping between ETH and xBTC changes both your exposure and the network your funds live on.

About Ethereum and OKX Wrapped BTC

What is Ethereum (ETH)?

Ether (ETH) powers Ethereum, a programmable blockchain proposed by Vitalik Buterin in 2013 and launched in July 2015 by a group of co-founders. Rather than acting only as money, Ethereum runs smart contracts, which let developers deploy applications that execute exactly as written.

How Ethereum works

Since the Merge in September 2022, Ethereum has been secured by Proof of Stake: validators lock up ETH, propose and attest to blocks, and can lose part of their stake for misbehaviour. Every operation on the network costs gas, paid in ETH: the base fee is burned, while validators receive a priority fee for including transactions.

What ETH is used for

ETH pays for transaction fees and is widely used as collateral in decentralized finance, from lending protocols to decentralized exchanges. Holders also stake it to help secure the network and earn protocol rewards.

ETH supply

Ether has no fixed maximum supply. New ETH is issued to validators, while the base fee of every transaction is burned under EIP-1559, so net supply can rise or fall depending on network activity.

Before you swap ETH

Make sure your withdrawal goes to an address on Ethereum mainnet and not to a layer-2 or another EVM network that uses the same address format. Gas prices on Ethereum fluctuate with demand, which can affect the cost of moving ETH in or out.

What is OKX Wrapped BTC (xBTC)?

xBTC is a wrapped version of bitcoin issued by the OKX exchange. It launched on 22 May 2025 on Solana, Sui and Aptos, and the OKX product page now lists X Layer as well. The aim is to let BTC holders use their coins in on-chain apps on those networks while keeping bitcoin price exposure.

How OKX Wrapped BTC works

OKX holds the reserve. Withdrawing BTC from an OKX account to a supported chain delivers xBTC one-for-one, and depositing xBTC back to OKX converts it to BTC. OKX says the reserves are fully in its custody and verifiable through on-chain Proof of Reserves, and that the token contracts were audited by CertiK, MoveBit, MixBytes and Zellic.

What xBTC is used for

On Solana, xBTC gives users a bitcoin-priced asset for lending, liquidity pools and trading against other Solana tokens. It also lets OKX customers move BTC exposure on-chain without a third-party bridge.

xBTC supply

There is no fixed cap or emission schedule. Supply expands and contracts as customers convert between BTC and xBTC through OKX, matched 1:1 by the exchange's bitcoin reserves.

Before you swap xBTC

xBTC is a custodial token, not native bitcoin: its backing depends on OKX, and redeeming it for BTC requires an OKX account. On Solana it is a standard SPL token (not Token-2022) with 8 decimals, and OKX keeps a freeze authority over it. Keep a little SOL for fees and token-account rent, or pick BTC as the output if you want coins on the Bitcoin network.
