Multi-Asset Checkout Cart SDK

overview

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for your specific Web3 use case.

We architect and deploy custom smart contracts that form the secure, automated backbone of your application. Our development process is built on audited code patterns and gas-optimized Solidity to ensure reliability and cost-efficiency from day one.

Custom Logic: Tailored ERC-20, ERC-721, or bespoke contracts for DeFi, NFTs, DAOs, and more.
Security-First: Development follows OpenZeppelin standards and includes comprehensive unit testing with Hardhat or Foundry.
Full Lifecycle: From initial design and development to deployment, verification, and ongoing maintenance on your chosen chain.

We deliver contracts you can trust, reducing audit time and mitigating the risk of costly exploits.

Our engineers focus on clear, maintainable code and provide detailed documentation, ensuring your team can seamlessly take ownership. We specialize in complex implementations like multi-signature wallets, vesting schedules, and upgradeable proxy patterns.

INTEGRATION FLEXIBILITY

Core SDK Capabilities

Our TypeScript SDK provides the building blocks to integrate multi-asset checkout into any application. Each module is production-ready, audited, and designed for developer velocity.

Unified Payment Interface

A single API endpoint to accept payments in 100+ tokens across 15+ chains. Handles token detection, price quoting, and transaction routing automatically.

Client Value: Launch a universal payment gateway in days, not months.

Gas Abstraction & Sponsorship

Let users pay with any token while you manage gas fees, or offer gasless transactions. Our relayer network ensures sub-2-second transaction submission.

Client Value: Eliminate UX friction and increase conversion by removing MATIC/ETH requirements.

Real-Time Price Oracle

On-chain verified price feeds with 0.5% max deviation. Aggregates data from 5+ major DEXs and CEXs for accurate, manipulation-resistant quotes.

Client Value: Prevent front-running and ensure users get the fair market rate for every swap.

Cross-Chain Settlement Engine

Atomic cross-chain swaps via bridges and liquidity pools. Our smart order routing finds the optimal path for cost and speed, with automatic fallbacks.

Client Value: Enable true multi-chain commerce without managing complex bridge integrations.

Compliance & Risk Module

Built-in AML checks, transaction monitoring, and wallet screening via integrated providers. Configurable rulesets for different jurisdictions.

Client Value: Deploy with enterprise-grade compliance out-of-the-box, reducing regulatory overhead.

Analytics & Webhooks

Monitor payment flows, conversion rates, and revenue in real-time. Get instant webhook notifications for successful payments, failures, and risk flags.

Client Value: Gain actionable insights to optimize checkout performance and automate business logic.

Frequently Asked Questions

Get clear answers on implementation, security, and support for your integrated crypto payment solution.

Standard integration takes 2-4 weeks from kickoff to production launch. This includes API integration, smart contract deployment for escrow logic, and end-to-end testing. Complex requirements like custom token whitelists or multi-chain settlement can extend this to 6-8 weeks. We provide a detailed project plan within the first 3 days of engagement.
