X Layer

OKB CMC #36 in the snapshot

X Layer is an Ethereum layer two associated with OKX. Current developer documentation describes an enhanced OP Stack network, so older descriptions of its initial zkEVM architecture should not be treated as the current design.

01 / THE PURPOSE

What is X Layer for?

It gives applications an Ethereum-compatible execution environment with separate block production and fees. Exchange integration can simplify access, but an exchange balance and a self-custodied X Layer balance remain different records.

02 / THE ARCHITECTURE

Three questions about the machinery.

How does it agree?

Consensus & security

A trusted sequencer orders transactions. The current architecture describes optimistic execution and a challenge process, with Ethereum providing underlying settlement. AggLayer pessimistic proofs support cross-chain accounting; their presence does not make every execution batch a conventional validity rollup.

Where do instructions run?

Execution model

Contracts run in an EVM-equivalent environment. Transactions can appear included locally before the relevant data, challenge and cross-chain settlement conditions are complete. The selected bridge determines how a deposit or withdrawal becomes usable at its destination.

What is the token for?

OKB in the system

OKB is the native gas asset. Having ETH on Ethereum does not automatically fund an ordinary X Layer transaction, and an OKB balance on an exchange is not automatically available to a wallet on the chain.

03 / THE DESIGN CHOICES

What comes with the design?

Each architecture makes choices about security, performance, coordination, and who can participate.

Sequencer control and upgrade powers remain relevant even when a network settles to Ethereum.
A bridge proof, a local inclusion message and final withdrawal availability describe different assurances.

04 / IN PRACTICE

Follow one use.

A user sends a token on X Layer and pays OKB. Returning that token to Ethereum involves the supported bridge’s separate settlement process, rather than only another local transfer.
