WASM Runtime Emulator Development | Chainscore Labs

overview

SECURE, AUDITED CODE

Custom Smart Contract Development

Build production-grade smart contracts with battle-tested security and gas optimization.

We architect and deploy secure, auditable smart contracts that form the core of your Web3 application. Our development process is built for enterprise-grade security and mainnet readiness from day one.

Full-Stack Expertise: Solidity/Vyper development for EVM chains, Rust for Solana, and Move for Aptos/Sui.
Security-First Process: Mandatory audits using Slither/MythX, formal verification, and integration with OpenZeppelin libraries.
Gas Optimization: We reduce transaction costs by up to 40% through efficient storage patterns and bytecode optimization.

We don't just write code; we deliver the foundational logic that secures assets and automates trust for your users.

Our deliverables include comprehensive test suites, technical documentation, and deployment scripts for seamless integration. We ensure your contracts are upgradeable where needed and immutable where required, with clear ownership and admin controls.

ENGINEERED FOR PRODUCTION

Core Capabilities of Our Runtime Emulator

Our WASM-based runtime emulator provides a deterministic, high-fidelity environment for testing, debugging, and optimizing your blockchain logic before mainnet deployment. Eliminate costly errors and accelerate your development cycle.

Deterministic Execution & State Forking

Test smart contracts and runtime upgrades in a sandbox that perfectly mirrors live chain state. Fork from any block height on networks like Polkadot, Kusama, or Astar to simulate complex, multi-step transactions with 100% reproducibility.

Gas & Fee Estimation

Precisely calculate transaction costs and optimize for gas efficiency before deployment. Our emulator provides detailed execution traces and fee breakdowns for Substrate pallets and smart contracts, preventing budget overruns.

Security & Upgrade Simulation

Safely test governance proposals, runtime migrations, and hard forks. Validate the security and correctness of upgrade paths in isolation, reducing the risk of chain halts or consensus failures during live deployments.

CI/CD Pipeline Integration

Automate testing and validation by integrating our emulator directly into your GitHub Actions, GitLab CI, or Jenkins pipeline. Run unit, integration, and load tests on every commit to ensure continuous delivery readiness.

TANGIBLE RESULTS

Business Outcomes: From Faster Development to Lower Risk

Our WASM runtime emulator isn't just a tool—it's a strategic asset that delivers measurable improvements to your development lifecycle and production security.

Accelerated Development Cycles

Test and debug smart contracts in a sandboxed, deterministic WASM environment that mirrors mainnet. Eliminate the need for expensive, slow testnet deployments for every iteration.

Key Benefit: Reduce development feedback loops from hours to seconds.

Up to 80%

Faster Iteration

< 2 sec

Test Execution

Eliminate Costly Mainnet Errors

Simulate complex, multi-transaction scenarios and edge cases before deployment. Our emulator provides full-state inspection and deterministic replay to catch logic flaws that unit tests miss.

Key Benefit: Prevent bugs that lead to irreversible financial loss or contract exploits.

Frequently Asked Questions

Get clear answers on how our WASM-based blockchain emulator accelerates your development and testing cycles.

A WASM (WebAssembly) runtime emulator is a high-fidelity, isolated environment that replicates the execution logic of a blockchain's virtual machine (like Substrate's FRAME or CosmWasm). You need it to test smart contracts and runtime upgrades with 100% accuracy before deploying to mainnet. It eliminates the cost and risk of using testnets by providing deterministic, local testing for complex state transitions and edge cases.
