Secure, audited smart contracts built for production on EVM, Solana, and other leading networks.
We architect and deploy production-grade smart contracts that power your core Web3 logic. Our development process ensures security-first design, gas optimization, and seamless integration with your frontend and backend systems.
Deliver a secure, audited MVP in as little as 2-3 weeks.
Our development stack includes:
What you get:
We turn your business logic into trustless, on-chain code that users and investors can rely on.
We build secure, scalable infrastructure that transforms your billing operations from a cost center into a competitive advantage. Our modular approach ensures rapid deployment and future-proof flexibility.
Deploy and manage a custom ERC-4337 Account Factory to create programmable smart accounts for your users. Includes gas sponsorship, batch transactions, and session keys for seamless user onboarding and retention.
Integrate a custom Paymaster to sponsor user transaction fees. We implement flexible policies for gas sponsorship, including fiat-based billing, subscription models, and whitelisted operations to reduce user friction.
Build a robust invoicing system with on-chain settlement. Features include automated invoice generation, multi-token payment support, escrow services, and immutable payment records for audit compliance.
Deploy and manage a high-performance Bundler to process UserOperations. We ensure sub-second inclusion, 99.9%+ uptime, and optimize for cost-efficiency across Ethereum, Polygon, and other EVM chains.
From smart contract development using OpenZeppelin libraries to full protocol audits, we embed security-first principles. Deliverables include formal verification reports and a bug bounty program setup.
Receive a fully documented REST/GraphQL API and an admin dashboard for real-time monitoring of accounts, transactions, and revenue. Enables easy integration with your existing CRM and accounting systems.
Integrating Account Abstraction Invoice Wallets delivers measurable improvements in user experience, operational efficiency, and security. Here's what you can expect.
Eliminate seed phrase complexity and gas fee prepayments. Users sign up with familiar Web2 methods, enabling instant transaction signing and payment approvals without holding native tokens.
Process hundreds of invoices in a single, gas-optimized transaction. Schedule recurring payments and automate treasury management, reducing manual overhead and transaction costs by up to 90%.
Implement multi-signature policies, spending limits, and transaction whitelisting at the wallet level. Maintain a clear, immutable audit trail for all invoice payments and approvals.
Deploy a unified invoice wallet interface across Ethereum, Polygon, Arbitrum, and other EVM chains. Manage cross-chain invoices and settlements from a single dashboard.
Cut administrative costs associated with manual invoice reconciliation and payment processing. Smart contracts automate validation and execution, freeing your team for strategic work.
Leverage our pre-audited, modular smart contract libraries and SDKs. Integrate fully functional invoice wallet capabilities into your platform in weeks, not months.
A phased approach to integrating Account Abstraction Invoice Wallets, from initial audit to full-scale enterprise operations.

A structured, four-phase approach designed to deliver secure, production-ready Account Abstraction invoice wallets with minimal disruption to your existing operations.
We conduct a technical deep-dive to map your payment flows, define gas sponsorship policies, and design a modular smart account architecture (ERC-4337) that integrates seamlessly with your backend.
Our team builds and rigorously tests custom Paymaster logic, Account Factory contracts, and invoice management modules. All code follows OpenZeppelin standards and undergoes internal security review.
We handle the full-stack integration, connecting your smart accounts to frontend SDKs (like viem/wagmi) and backend relayers. Testing includes multi-chain simulations and edge-case failure modes.
Managed production deployment with comprehensive monitoring dashboards for gas usage, user adoption, and transaction success rates. We provide ongoing support and optimization recommendations.
Secure, production-ready smart contracts built by Web3 experts to power your protocol's logic.
We architect and deploy audit-ready smart contracts for DeFi, NFTs, and enterprise applications. Our development process is built on Solidity 0.8+ with OpenZeppelin standards, ensuring security and gas efficiency from day one.
From concept to mainnet, we deliver contracts that are secure, upgradeable, and built for scale.
We provide complete technical documentation and a comprehensive handover, enabling your team to own and iterate on the codebase. Typical delivery for a core protocol MVP is 3-4 weeks.
Get clear answers on timelines, security, and integration for your automated payment solution.
Standard deployments take 2-4 weeks from kickoff to mainnet launch. This includes smart contract development, integration with your existing invoicing system, and end-to-end testing. Complex multi-chain deployments or custom payment logic may extend this to 6-8 weeks. We provide a detailed project plan with weekly milestones.
