overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
Deliver a market-ready, audited contract suite in as little as 2-4 weeks.
- Protocol Development: Custom logic for DeFi (DEX, lending), NFTs (ERC-721A, 1155), DAOs, and enterprise use cases.
- Security & Auditing: Multi-stage review using static analysis (
Slither,MythX) and manual review for critical vulnerabilities. - Gas Optimization: Write efficient
Solidity 0.8+code to minimize user transaction costs and maximize throughput. - Full Lifecycle Support: From initial design and testing (
Hardhat,Foundry) to mainnet deployment and upgrade management via transparent proxies.

ENTERPRISE-GRADE INFRASTRUCTURE
Core Capabilities of Our NEAR Billing Systems
We build production-ready, secure billing systems on NEAR Protocol that reduce operational overhead and accelerate your time-to-market. Our solutions are designed for high-volume, compliant enterprise use.
01
Gasless Transaction Sponsorship
We implement sponsored transactions so your end-users never need to hold NEAR tokens or manage gas fees. This removes the primary friction point for mainstream adoption and enables seamless subscription payments.

NEAR Account Abstraction
Frequently Asked Questions
Get clear answers on how we implement enterprise-grade billing solutions using NEAR's Account Abstraction.
NEAR's Account Abstraction allows us to create programmable, gasless transactions and sponsored transaction flows. This means your enterprise can:
- Bill end-users in fiat while settling in crypto on-chain.
- Remove wallet complexity for your customers with session keys or email/social logins.
- Implement complex subscription models and automated payments directly in smart contracts.
- Achieve predictable costs by sponsoring gas fees and absorbing them into your service model. We've built systems handling over $10M in monthly recurring billing using this architecture.
