What is X Layer and how to use it. How the L2 network works, how to transfer tokens via bridges, how to check transaction status, and what to do if withdrawals are delayed
X Layer is a Layer 2 network for the Ethereum ecosystem, integrated with OKX’s infrastructure. For users, it offers practical benefits: lower fees, faster transactions, and access to dApps in an EVM-compatible environment. In current documentation, X Layer is described as an Ethereum Layer 2 solution built by OKX on the enhanced Optimism Stack, featuring EVM equivalence, 1-second blocks, and gas in OKB.
A specific detail regarding the name is important for searching for information. Previously, the network was referred to as X1 in public communications, but the current infrastructure and documentation use the name X Layer. This is the current public name of the network in 2026.
What is X Layer in simple terms
What is X Layer in simple terms? X Layer is an EVM-compatible Layer 2 network for Ethereum. It is designed to process transactions and run dApps faster and more cheaply than on the Ethereum mainnet. The X Layer developer documentation explicitly refers to it as an Ethereum Layer 2 network with full EVM equivalence.
For the average user, this means one simple thing: many familiar wallets, addresses, and contracts operate in a way that’s familiar from Ethereum, but transactions take place on L2. At the same time, the network is connected to the OKX ecosystem via OKX Wallet, OKLink, and other internal tools, so you can check blocks, transactions, and transfer statuses within the proprietary infrastructure, rather than relying solely on third-party services.
How X Layer Works: Core Components and Operational Logic
X Layer is designed so that execution takes place in L2, while the final state and data are linked to Ethereum. The current documentation states that the network runs on the OP Stack, uses a trusted sequencer, and provides fast L2 execution for most operations with data published to L1. For the user, it looks simple: a transaction on X Layer is confirmed faster than on the Ethereum mainnet, and the model itself reduces transaction costs.
EVM compatibility here means that applications and wallets from the Ethereum ecosystem do not need to be adapted for a new virtual machine. The X Layer overview explicitly states “Full EVM Equivalence: deploy existing Ethereum applications without code modifications.” This is important for both developers and users, who can connect a standard Web3 wallet and interact with dApps in a familiar format.
Where can you view transactions and blocks? The basic option is the X Layer explorer on OKLink. There, you can find lists of blocks, transactions, pending operations, and a separate page for L2→L1 bridge transactions. Additionally, X Layer is integrated into the OKX Wallet infrastructure, where you can also track activity and address formats.
X Layer and Cross-Chain Bridges: How Asset Transfer Works
The X Layer and cross-chain bridges. A bridge is needed to transfer an asset from one network to another. In practice, this involves locking or accounting for the asset on one side and issuing or unlocking its equivalent on the other side. The X Layer architectural description includes separate flows for L1→L2 and L2→L1: the user deposits the asset into the bridge contract, the bridge service tracks the event, after which a claim or mint occurs on the X Layer side, and when withdrawing back, the transaction goes through the finalization stage on L1.
The practical risk here is significant. Official infrastructure and supported routes change over time, and some cross-chain transfers may go through third-party providers. Therefore, the security rule is simple: always verify the destination network, address, token, fee, and receipt format before confirmation. And for sensitive transfers, send a minimal amount first. This is especially important in Layer X, where there are two address display formats.
How to Transfer Tokens to X Layer
How to transfer tokens to X Layer. The general transfer process is as follows: select the source network, connect your wallet, select the token, specify the X Layer network as the destination network, confirm the transaction, and wait for the funds to be credited. The specific interface depends on which bridge or aggregator the user is using, but the basic logic is the same. The X Layer bridge flow is described in the documentation as L1 deposit → event sync → L2 claim or mint → block inclusion → balance update.
You also need to consider the address format. In X Layer, an address can be displayed as XKO or as a regular 0x. The documentation explicitly states that these addresses are equivalent to on-chain addresses and differ only in the prefix. However, there is an important limitation: XKO is used for off-chain display and RPC/UI interactions, while the standard 20-byte address format must be used when manually constructing transactions. Otherwise, the network will reject such a transaction.
Before sending, it’s helpful to go through a short checklist:
check the source network and destination network;
make sure you’re sending the correct token, not a similar contract;
verify the recipient’s address and network format;
check the fee and gas;
check the limits, minimum amount, and any service restrictions;
estimate the approximate time of crediting;
save the transaction hash immediately after sending.
Another detail from the technical specifications is confirmed by the practice of Layer 2 networks: during maintenance and updates, deposits and withdrawals may be temporarily suspended. Therefore, before making a large transfer, it is wise to check the status of the network and services, rather than relying solely on the wallet interface. In X Layer, this is especially important for bridge and L2→L1 claim operations, where delays may be related not only to the block itself but also to the finalization phase.
How to Check the Status of an X Layer Transaction
How to check the status of an X Layer transaction. To check the status, you need the transaction hash. You can usually find it in your wallet, transaction history, or the bridge interface immediately after confirmation. Next, enter this hash into a blockchain explorer. For X Layer, the main tool for checking is the OKLink X Layer explorer.
On the transaction page, you should check several fields: status, block number, time, sender and recipient addresses, the fee paid, and, if it’s a cross-chain transaction, the relationship between the L2 and L1 hashes. For bridge transfers, the separate L2–L1 transactions page in OKLink is convenient, where you can see whether the associated L1 transaction has been confirmed or is still showing as a Pending claim.
The second verification option is through the tools within the OKX Wallet, where X Layer is already supported as a network. However, if you need the most accurate technical status, the explorer usually remains the primary source, because that is where you can see the block, fee, transaction type, and sequence of steps in the bridge transfer.
What to do if a transfer is stuck in X Layer
What to do if a transaction is stuck in the x layer. First, check the transaction hash, then verify the network and address, then check the status in the explorer, check the bridge stage if the transaction went through a bridge, make sure the fee has been paid, and only then decide whether to wait longer or contact support. In most cases, “stuck” does not mean a loss of funds, but rather a processing status or waiting for the next step. This is especially evident on bridge pages, where some transactions are displayed as “Pending claim” rather than “failed.”
The procedure is as follows:
find the transaction hash in your wallet or service;
check it in the OKLink X Layer explorer;
verify the address, destination network, and token;
if a bridge was used, check the status of each step;
make sure there are sufficient funds on the destination side to cover the fee;
wait a reasonable amount of time if the network is congested or a claim is in progress;
if the status does not change, contact the service or bridge support, attaching the hash and details.
What not to do:
Do not send a duplicate transaction at random;
Do not change the network in your wallet without understanding exactly what happened;
Do not trust “helpers” in private messages;
Do not share your seed phrase or private keys;
Do not sign unfamiliar transactions just to “unlock” funds.
What are the risks of using X Layer?
What are the risks of using X Layer? The main risks here are not unique to any single network: these include bridge risks, risks associated with the wrong network or address, phishing, fake interfaces, errors with token contracts, temporary downtime during updates, and the risk of a malicious signature in the wallet. In the case of X Layer, there is an additional nuance regarding XKO and 0x addresses: the formats are equivalent on-chain, but they must be used correctly and with an understanding of where the format is acceptable and where it is not.
Basic precautions help mitigate risks: verify domains and contracts, start with a small amount, save transaction hashes, use an official blockchain explorer, do not share your seed phrase, and do not confirm suspicious requests. This is especially important for bridges because a user error and an error from an external bridge service look identical until the first check in the explorer.
X Layer in 2026 already looks like a full-fledged L2 infrastructure with EVM compatibility, an explorer, bridge logic, and its own addressing features. But the rule of thumb remains the same as for any cross-chain transaction: first verify the network, token, and address; then make a test transfer; then send the main amount.
