We’re excited to announce that Tenderly now supports X Layer, OKX’s Ethereum Layer 2 network. From now on, developers building on X Layer can use Tenderly Debugger and Transaction Simulations to deeply inspect, test, and validate their smart contracts - all in one place.
OKX launches X Layer
When OKX introduced X Layer, the goal was refreshingly straightforward: make building onchain feel fast, accessible, and cost-efficient, without compromising Ethereum-grade security.
Built with OKX’s high-performance L2 infrastructure, X Layer delivers low-latency transactions at extremely low cost. With negligible fees and full EVM equivalence, developers can deploy existing Ethereum contracts without modification and ship new features with confidence. The network is designed to handle high throughput while maintaining Ethereum-level security guarantees, giving builders a scalable and predictable environment for production-grade applications.
X Layer also pairs their high-performance Layer 2 environment with OKX’s massive product suite — a combination rarely seen elsewhere in an ecosystem. It's exactly the type of high-energy, fast-growing environment where developers need reliable, professional-grade tooling to keep up.
Why should you build on X Layer
For developers, X Layer strikes a compelling balance:
- Speed for iteration: Fast confirmations mean faster testing, debugging, and deployment cycles.
- Low fees for experimentation: Builders can try, break, and rebuild without thinking about gas costs.
- Enterprise-grade enhancement: 99.99% uptime for production environments using X Layer’s Conductor high-availability cluster for sequencer redundancy.
- Built-in distribution: OKX’s 50M+ users, wallet ecosystem, and platform integrations form a natural funnel for dapps.
- Growing, active builder ecosystem: Many projects are already shipping on X Layer across DeFi, gaming, payments, and infra.
Combined with Tenderly Debugger and Simulations, developers gain visibility, predictability, and safety on top of an already high-performance chain.
What this integration delivers
This release is focused on the most critical part of the developer workflow: understanding exactly what your code is doing — before your users do.
Transaction Debugger
The Tenderly Debugger gives you full transparency into any X Layer transaction. Paste a transaction hash and instantly see what happened under the hood:
- Every function call
- Every revert and its root cause
- Every storage write
- Every event and log
- The exact line of code where the behavior changes
No more digging through hex output, no more “why did this fail?” guesswork. Whether you're building complex DeFi logic, game mechanics, or a multi-contract system, you get the full execution story in seconds.
Transaction Simulations
Simulations let you preview exactly how a transaction will behave before you send it. You can:
- Test any interaction or contract call
- Inspect state changes, gas consumption, and execution flow
- Validate upgrades or new features safely
- Experiment without spending OKB
- Reproduce user issues to resolve them quickly
Simulations also support state overrides, so you can model scenarios that don’t exist on-chain yet — perfect for protocol upgrades, liquidity changes, governance proposals, or edge-case testing.
Tailored for X Layer
X Layer’s execution environment has its own nuances around how transactions are processed and confirmed. Tenderly abstracts those details for you automatically. Whether you're debugging a newly confirmed transaction or simulating against the latest network state, results remain accurate, consistent, and aligned with how X Layer behaves in production.
Get started in seconds
If you're already building on X Layer, you can start using Tenderly immediately:
- Open the network page in Tenderly dashboard
- Choose X Layer (mainnet or testnet)
- Paste any transaction hash to debug
- Run simulations directly from the dashboard or your CI pipeline
No additional setup. No configs. Everything works out of the box.
If you're new to X Layer, the combination of fast, inexpensive transactions and Tenderly’s tooling gives you a development environment where you can move quickly without cutting corners.
Build, test, and scale with ease with Tenderly on X Layer.
