A PROVEN FRAMEWORK
Our Development & Delivery Process
We deliver production-ready multi-chain aggregator cards through a structured, transparent process designed for speed, security, and scalability. From concept to deployment, our methodology ensures your product launches on time and exceeds technical expectations.
01
Discovery & Architecture Design
We conduct a deep technical workshop to define your target chains (EVM, Solana, Cosmos), user flows, and liquidity requirements. The output is a detailed technical specification and architecture diagram for your aggregator card's smart contracts and off-chain components.

Frequently Asked Questions
Get clear answers on timelines, costs, and technical details for your project.
A multi-chain aggregator card is a non-custodial smart contract wallet that consolidates assets and DeFi interactions across multiple blockchains (e.g., Ethereum, Polygon, Arbitrum, BSC) into a single interface. The core benefits we deliver are reduced gas fees via optimized routing, unified liquidity access across 10+ DEXs, and a dramatically simplified user experience that abstracts away chain-switching complexity. For businesses, this translates to higher user retention and increased transaction volume.
