CASE STUDY: SDK INTEGRATION

Pennysia

Unified Liquidity Marketplace for DeFi

For liquidity marketplaces and aggregators that want intent-based execution, cross-chain liquidity, all through a single integration.

The Partner

Pennysia connects all liquidity worldwide. No more searching across DEXs, aggregators, RFQs, and countless liquidity sources: users access them all in one marketplace with the best prices, fair competition, and double-layered security. One platform, infinite markets. Pennysia is building a unified liquidity infrastructure for DeFi on Ethereum. At the protocol layer, it is developing a new AMM primitive designed to improve the LP tradeoff between principal protection, yield, and passive participation. Alongside that, it is building an execution layer focused on consistently sourcing superior pricing, allowing Pennysia to offer the true best price at any given time.

The Challenge

Liquidity is scattered, and reaching the best of it is hard. Any marketplace that wants to unify it faces the same structural gaps:

Liquidity is fragmented. It is spread across DEXs, aggregators, and countless sources. No single venue holds the best price.

Reach is limited to one chain. Sourcing the true best price is harder when liquidity is out of reach.

Building cross-chain execution is heavy. Standing up the infrastructure to settle across many networks is a large undertaking on its own.

The Solution

Pennysia integrated SODAX to tap into cross-chain liquidity and deliver a better swap experience, all through a single intent.

1

Intent-Based Swaps

SODAX provides the execution infrastructure to connect with over 20 networks and access to 120+ assets, so a single intent can source quotes across a broad cross-chain market.

Unified Liquidity from Day One

SODAX provides access to liquidity across the different venues Pennysia's infrastructure is integrated to, giving the marketplace unified liquidity from the moment it goes live.
