At a small tech center in Lagos, Nigeria, a young programmer named Aisha is coding a lending protocol that will connect local entrepreneurs with global capital. Her platform, on the Flow blockchain, settles loans in seconds, effectively cutting out the expensive middlemen characteristic of traditional finance. Aisha's efforts are rooted in a revolutionary upgrade known as Crescendo, which is being spearheaded by Chirag Narang. This effort, which has brought Ethereum Virtual Machine (EVM) equivalence to the Flow blockchain, has significantly advanced it as a center of decentralized finance (DeFi), thereby facilitating developers like Aisha to construct inclusive financial instruments at unprecedented ease.

The World Bank suggests that nearly 1.7 billion adults worldwide do not have access to formal financial systems, frequently depending on high-fee intermediaries for lending or remittances. DeFi has the potential to disrupt this by providing peer-to-peer solutions that are more accessible and less expensive. Most blockchains, however, fall into the trap: either they serve niche ecosystems or they compromise performance for interoperability. Crescendo by Narang disrupts this constraint by merging Flow's usability with Ethereum's large developer ecosystem, thus creating a platform where innovation and accessibility converge.

Revealing Flow's Potential

Flow, with consumer-focused apps, has had superior scalability and user experience over the years due to its Cadence smart contracts and user-controlled accounts. Relying on its bespoke architecture, it existed in isolation from Ethereum, the leading DeFi platform with more than $50 billion of TVL in 2024. Developers had a high barrier to entry to develop on Flow, and EVM incompatibility restricted the use of Ethereum's tooling, wallets, and liquidity.

"Flow had immense potential, but it was an island in the world of DeFi," Narang continues. "It was imperative that we connect it to Ethereum without sacrificing the unique aspects that made Flow stand out."

As Dapper Labs' Crescendo release Head of Product, Narang faced a multi-faceted challenge: achieving EVM equivalence without compromising Flow's performance and user-first design. The challenge was to enable native execution of Solidity-based smart contracts on Flow, support Ethereum wallets like Metamask, and finish bridging assets seamlessly. All this needed to be done with the state migration of 25 million active users who possess hundreds of millions of assets. Convincing stakeholders from management to developers added complexity, as the use of EVM would risk diluting Flow's identity.

A Hybrid Blockchain Ecosystem

Narang's vision for Crescendo was to transform Flow into a two-in-one blockchain, leveraging Ethereum's developer familiarity with the scalability of Flow. He advocated for this vision, tying it to Flow's long-term vision of mass adoption, and drove cross-functional teams to bring it to life.

The Crescendo upgrade added complete EVM equivalence, enabling Solidity contracts to execute on Flow without modification. Narang worked with engineers to introduce an EVM execution environment, exposing Ethereum's JSON-RPC API to enable tools like Remix and Hardhat. Developers were able to deploy DeFi protocols such as Uniswap on Flow with minimal effort, tapping into Ethereum's ecosystem while benefiting from Flow's sub-second finality and high throughput.

One of the innovations was Cadence-EVM composability, which provided synchronous interactions between Flow's resource-based Cadence contracts and Solidity-based contracts. Narang's group created bridged accounts, allowing Cadence-managed assets to be utilized in the EVM ecosystem, so users could seamlessly switch between ecosystems. A bi-directional asset bridge system also enabled ERC-20 and ERC-721 tokens to switch between platforms, offering liquidity for DeFi applications.

To make adoption easier, Narang emphasized developer enablement through documentation, SDKs, and tutorials. He collaborated with ecosystem partners, offering incentives to bridge operators and liquidity providers, and addressed concerns from Cadence developers worried about EVM's impact. The result was a hybrid blockchain that retained Flow's usability features like account abstraction without compromising on Ethereum's 100k+ developers.

Narang says, "Crescendo wasn't about the tech; it was about enabling developers to build solutions that help their communities, whether that's a lending platform in Africa or an Asian stablecoin market."

A New Era for Flow and DeFi

The Crescendo launch in September 2024 revolutionized Flow. Within a few months, the blockchain's DeFi TVL surpassed $90 million, ranking it in the top 50 chains on DeFiLlama. ETHGlobal hackathon developer activity doubled, with over 500 Solidity-based apps shipped within less than three months. During Q1 2025, Flow boasted 150,000+ deployed smart contracts, reflecting a DeFi innovation explosion.

The real-world effects are being felt. In low-banking regions such as Southeast Asia, In Latin America, stablecoin deployments on Flow, driven by Crescendo, allow users to hedge inflation, with some local DeFi activity originating from such activities. Aisha's lending platform in Lagos, for example, has facilitated thousands of loans, bringing local entrepreneurs in touch with global sources of liquidity.

Narang cites, "Crescendo made Flow a home for developers who want to solve real problems." He adds further, "It's not so much about token trading; it's about empowering people."

The upgrade also supported the competitive standing of Flow. By being among the very few non-EVM chains to provide native Solidity execution with sub-second finality, Flow successfully enticed Ethereum and other ecosystem projects. Collaborations with Ethereum-native teams, like LayerZero and Opensea, also widened its base, with over three dozen projects now testing on Flow's development network.

A Broader Vision for DeFi

Crescendo's success is only an example of a larger trend in decentralized finance (DeFi): the alignment of ecosystems dedicated to creating inclusive finance systems. Connecting Flow and Ethereum, Narang has proved that blockchains can collaborate rather than compete, thus unleashing possibilities for developers and users alike. His work challenges the fragmentation that often puts DeFi's potential at risk, fostering a network where assets and ideas flow freely.

In the next few years, Narang sees a world where decentralized finance (DeFi) is as easy to access as online banking, with Flow blockchain as a backbone of onboarding billions of users with exposing intricacies of blockchains. "We're creating tools that enable anyone, anywhere, to use finance on their terms," he states. "It could be a Vietnamese farmer or a Silicon Valley company, it's the same mission: empowerment."

To entrepreneurs such as Aisha, Crescendo is not just an evolution; it's an entry point to making an impact. Her lending protocol, which is already live on Flow's mainnet, processes thousands, demonstrating that DeFi can break out of crypto enthusiasts to change lives. As Narang pioneers the way, his contributions to Crescendo are a reflection of DeFi's potential: a reality where financial obstacles dissolve, and possibilities are endless for everyone.
