# Introduction

Swapper Finance is building payment and onboarding infrastructure that connects traditional finance with Web3. We help platforms make deposits simple for users, and we help ecosystems bring stablecoin liquidity into new environments through standardized cross-chain infrastructure.

For applications, Swapper Deposits makes it easy for users to fund their accounts directly with cards, existing crypto, or Web3 wallets. For chains and protocols, the Swapper Stablecoin Payment Layer provides a cleaner path to bring Bridged USDC into their ecosystem without relying on fragmented bridge variants or pool-based liquidity.

Think about it this way. There are 3.5 billion cardholders worldwide who could be using DeFi right now, but aren't. At the same time, on-chain activity is spreading across more chains, and every ecosystem needs reliable stablecoin access before users and protocols can really grow.

Swapper brings these pieces together: simple deposit flows for users, and stablecoin infrastructure for the ecosystems they want to enter.
