overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Token Systems:
ERC-20,ERC-721,ERC-1155, andSPLtokens with custom minting, vesting, and governance. - DeFi Protocols: Automated market makers (AMMs), lending/borrowing pools, staking mechanisms, and yield aggregators.
- Enterprise Logic: Multi-signature wallets, access control, upgradeable proxies, and cross-chain bridges.
We deliver battle-tested code with a 99.9% uptime SLA and a typical MVP deployment timeline of 2-3 weeks.
Our contracts are built with Solidity 0.8+ or Rust, utilize OpenZeppelin libraries, and follow formal verification patterns to mitigate reentrancy and overflow risks before your first audit.

STRUCTURED & PREDICTABLE
Our End-to-End Migration Process
A proven, phased approach that minimizes risk and ensures a seamless transition from your legacy system to a high-performance Plasma chain. We manage the entire lifecycle from initial assessment to post-migration support.
01
Discovery & Architecture Review
We conduct a comprehensive audit of your existing smart contracts, tokenomics, and user flows to define the optimal Plasma architecture. This phase establishes the technical blueprint and migration roadmap.

Technical & Commercial Questions
Plasma Chain Migration FAQs
Answers to the most common questions CTOs and technical founders ask when evaluating a Plasma chain migration partner.
A standard Plasma chain migration project with a defined scope is typically completed in 6-10 weeks. This includes the audit of the existing state, smart contract refactoring, testnet deployment, and mainnet launch. Complex protocols with custom fraud proofs or extensive state may extend to 12-14 weeks. We provide a detailed, phase-gated project plan in our initial technical assessment.
