X Layer Wallet Guide: Send OKB and Pay Gas on OKX's L2

X Layer addresses and the OKB gas coin

Your X Layer address is a standard 0x address derived from your recovery phrase, identical to your Keylo address on Ethereum and every other EVM network. You do not need to activate it, keep a minimum balance or add a memo, and Keylo verifies the checksum before sending.

The native balance on X Layer is OKB, not ETH. ETH on X Layer is a wrapped token, so it cannot pay fees. Likewise, OKB withdrawn from an exchange on the Ethereum network arrives as an ERC-20 at your Ethereum address and cannot pay X Layer gas. Always check that OKB arrives on the X Layer network if you plan to transact there.

OKT Chain, OKX's older network, has been retired. Do not send anything to an OKT Chain option you might still see in old guides or apps; X Layer is the active network. OKT Chain also used 0x-style addresses, which is exactly why an outdated network option is easy to pick by mistake when your address looks valid everywhere.

Create an X Layer wallet with Keylo

1. 1

   Visit Keylo's sign-up page in any modern browser.

2. 2

   Complete the short form with your name, email, phone and password, then confirm your email.

3. 3

   Keylo creates your 12-word recovery phrase in the browser and encrypts it locally with a key derived from your password. Keylo's servers see only the encrypted copy.

4. 4

   Back up the phrase in Settings after re-entering your password.

5. 5

   Select X Layer in the network list to see your OKB balance and 0x address.

How to receive OKB on X Layer from OKX

1. 1

   In Keylo, open X Layer, tap OKB and tap Receive. Copy the address labeled X Layer.

2. 2

   In the OKX app, start a withdrawal of OKB and paste your Keylo address.

3. 3

   Choose X Layer as the network. Choosing the Ethereum (ERC-20) option sends OKB to Ethereum instead.

4. 4

   Confirm the withdrawal in OKX and wait for it to appear in Keylo's Activity.

5. 5

   Repeat for USDT or other tokens, making sure each one is withdrawn on X Layer.

How to send OKB and tokens on X Layer

Sending back to OKX is straightforward: copy your OKX deposit address for the asset, confirm the deposit page lists X Layer, and send from Keylo on X Layer. For other exchanges, check support first, since many do not list X Layer as a deposit network.

1. 1

   Open X Layer in Keylo and choose OKB or a token.

2. 2

   Paste or scan the recipient's address. Keylo checks the checksum and warns about contract addresses.

3. 3

   Enter an amount or tap Max; for OKB, Max leaves enough for the fee.

4. 4

   Choose a fee speed. X Layer is designed for low fees, so normal is usually enough.

5. 5

   Review the summary showing the fee in OKB and the exact amount, then confirm.

How fees work on X Layer

X Layer uses the OP Stack fee model with OKB as gas. Each transaction pays an execution fee, gas used times an EIP-1559 base fee plus a priority tip, and a data fee that covers publishing transaction data to Ethereum as blobs. Because Ethereum's costs are in ETH, the network converts that data cost into OKB when charging you.

Fees are designed to be very low, so a simple transfer costs a tiny amount of OKB. Your fee in dollar terms still moves with OKB's market price and with Ethereum data costs. Keylo shows the exact fee in OKB before you confirm and adds nothing to normal sends.

Keep a small OKB buffer on X Layer at all times. Without it, tokens such as USDT or wrapped ETH are stuck until someone sends you OKB or you bridge some in, and a stuck balance usually means a slower and more expensive fix than simply keeping a reserve.

Tokens on X Layer

X Layer supports ERC-20 tokens, which Keylo can show and send. You will typically find USDT, USDC, wrapped ETH, wrapped OKB for apps that need an ERC-20 version, and tokens from X Layer DeFi and payment apps. Each token on X Layer has its own contract address, different from the same asset on Ethereum.

Exchange-linked networks attract fake tokens using OKX branding and fake OKB airdrop sites. OKX does not ask for recovery phrases, and real promotions run inside OKX's own apps. Ignore unexpected tokens, never approve contracts linked from token names, and verify contracts on the OKLink explorer.

Swap and bridge on X Layer

Keylo's swap and bridge works on X Layer, so you can swap USDT or wrapped ETH into OKB for gas, or bring assets in from Ethereum, BNB Smart Chain and other networks without going through an exchange. LI.FI provides routes through decentralized exchanges and audited bridges, and THORChain provides native cross-chain swaps. The quote breaks down the route, expected output, minimum received and every fee, including any small service fee, before you sign. A bridge can be tracked until it lands; if a cross-chain route cannot complete, the protocol refunds your sending wallet.

X Layer also has an official bridge to Ethereum. Withdrawals through it wait for the state to be posted and a dispute window to pass, which can take days, and the bridge interface shows the current estimate. For many people the quickest exit is simply depositing to OKX on X Layer and withdrawing from OKX on the network they need.

When bridging in, choose the output token with gas in mind. A route that delivers only USDT leaves you unable to move it, while a route that delivers some OKB gets you started immediately. If a quote looks expensive for a small amount, compare it with a direct OKX withdrawal on X Layer, which is often the cheapest way to fund the network.

What it means to use an exchange-run layer 2

X Layer gives you something an exchange account does not: your funds sit at an address controlled by your own recovery phrase, and OKX does not hold them for you the way it holds exchange balances. At the same time, OKX operates the network itself. It runs the only sequencer that orders transactions, a small multisig can upgrade the bridge contracts, and the network's roadmap follows OKX's business decisions, as the 2025 move to the OP Stack and the OKB changes showed.

For everyday payments and DeFi that is a reasonable trade-off, especially if you already use OKX. If you plan to hold large amounts long term, compare that trust model with networks secured more fully by Ethereum, and keep your recovery phrase backed up so you can always move funds elsewhere if your plans change.

X Layer safety tips

• Keep OKB on X Layer for gas; ETH on X Layer is a token.
• Pick X Layer, not Ethereum (ERC-20), when withdrawing OKB from OKX for use on X Layer.
• Ignore OKT Chain options; that network has been retired.
• Verify token contracts on OKLink, and ignore fake OKX promotions.
• Remember the trust model: OKX runs the sequencer and controls upgrades.
• Read how Keylo protects your keys and compare with BNB Smart Chain, another exchange-linked network.
