Turnkey Launches Swaps and Earn to Monetize Embedded Wallets with In-App Trading

Turnkey has launched Swap and Earn, two new capabilities designed to embed in-app trading and onchain yield directly into digital products. For fintech developers, this removes the friction of building fragmented execution and billing infrastructure, allowing them to monetize user activity through customizable fee structures while maintaining security via Turnkey’s existing private key management framework.

What was announced

The launch of Swaps and Earn allows developers to integrate financial features into their applications without the need for redirects or the assembly of multiple third-party providers. Swaps enable users to trade assets both within a single network and across different networks. This capability is available on a broad range of chains, including Ethereum, Base, Arbitrum, Polygon, Tempo, BNB Chain, Monad, Optimism, Solana, and Robinhood Chain. A key feature of the Swaps product is its ability to facilitate trades between EVM-compatible networks and Solana, with Turnkey sourcing quotes from various liquidity venues to ensure competitive pricing.

The Earn feature provides users with access to onchain lending vaults, allowing them to put idle balances to work. Turnkey has integrated with established providers such as Morpho and Aave to facilitate these services. Earn is currently supported on Ethereum, Base, Arbitrum, Polygon, Tempo, Optimism, Monad, and BNB Chain. Developers retain control over which specific vaults are enabled for their users, managing discovery, deposits, and withdrawals through a single API.

Both capabilities are built with a focus on monetization. Developers can set their own fee structures for every transaction; Swap fees are paid out in USDC, while Earn fees are taken as a share of the yield generated. These features are secured by Turnkey’s policy engine, which records every swap, deposit, and withdrawal in a unified audit trail alongside other platform actions.

"Historically, adding trading or yield to a product meant assembling it piece by piece. You wired up a swap router, connected to lending vaults, built execution and routing logic, then bolted billing on top to actually make money from it. Every one of those pieces was a separate provider you needed to integrate and maintain. Each introduced another API, contract, dependency, and security surface for your team to manage, along with more infrastructure to monitor as protocols, networks, and liquidity sources changed."

The companies involved

Turnkey (https://www.turnkey.com/) provides the core infrastructure for private key management and signing that underpins these new features. The company’s platform is designed to handle the security and policy requirements of institutional and developer-led crypto products. Morpho (http://www.morpho.org) and Aave (https://aave.com/), the primary yield sources for the Earn product, are established decentralized lending protocols that allow for automated interest generation.

The announcement involves a wide array of blockchain networks, including Ethereum (http://www.ethereum.org), the foundational smart contract platform, and Layer 2 solutions such as Base (https://base.org/), Arbitrum (https://arbitrum.io/), Polygon (https://polygon.technology/), and Optimism (https://optimism.io/). It also incorporates BNB Chain (http://www.bnbchain.org), Solana (https://solana.com/), and emerging networks like Monad, Tempo (http://www.tempo.com.vc), and Robinhood Chain. This cross-chain approach reflects a market shift toward interoperability, particularly between EVM-compatible environments and the Solana ecosystem.

What this means

The launch of Swap and Earn signals a shift in the fintech stack from simple custody to active revenue generation. By embedding monetization directly into the API, Turnkey is challenging the traditional model where developers had to build custom billing logic to capture value from DeFi activity. This puts pressure on standalone wallet-as-a-service providers who lack integrated liquidity and yield routing. The inclusion of Solana alongside EVM chains suggests that the industry is moving past network tribalism in favor of unified liquidity. The central question for the sector now is whether embedded financial features will lead to a fragmentation of liquidity across thousands of small apps or a consolidation around a few dominant infrastructure providers.
