overview
CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built for production by Web3-native engineers.
We deliver battle-tested code with a zero critical-bug track record in production deployments.
- Full Lifecycle Development: From initial architecture and
ERC-20/721/1155implementations to complex DeFi logic and DAO governance systems. - Security-First Process: Multi-stage audits, formal verification with tools like Slither and MythX, and comprehensive unit/integration testing.
- Production Ready: Contracts are deployed with proxy patterns for future upgrades, include pause/unpause functionality, and are optimized for mainnet gas costs.
Our engineers have deployed over 200+ contracts across EVM chains like Ethereum, Polygon, and Arbitrum. We ensure your core business logic is immutable, secure, and performs as intended.

TANGIBLE RESULTS
Business Outcomes for Your Platform
Integrating Hedera or Algorand fee delegation isn't just a technical feature—it's a strategic lever for growth. We deliver measurable improvements to your core business metrics.
01
Accelerated User Onboarding
Remove the friction of acquiring native tokens. Users can transact immediately, reducing the sign-up to first transaction time from days to seconds. This directly increases activation rates and lowers acquisition costs.

Technical & Commercial Considerations
Fee Delegation Integration: Key Questions
Common questions from CTOs and product leads evaluating Hedera and Algorand fee delegation solutions.
A standard integration takes 2-4 weeks from kickoff to production deployment. This includes smart contract development, backend API integration, and a full security audit. Complex multi-chain or custom sponsorship logic can extend this to 6-8 weeks. We provide a detailed project plan within the first 3 business days.
