Metlabs explores smart contract structure at the MERGE Tech Summit
Isaac González delivered a session with EVM and non-EVM examples and a Remix IDE demonstration at Madrid’s IE Tower.
Metlabs took part in the MERGE Madrid Tech Summit on October 10, 2025, at IE University’s IE Tower. Isaac González, the company’s Head of Innovation, delivered a session on the components of a smart contract and how they work across different blockchain environments.
The event continued the MERGE week with a day dedicated to development and technology infrastructure. Metlabs’ session combined an explanation of concepts with a practical demonstration, connecting the structure of the code with its execution and giving the audience a concrete example to follow.
The anatomy of a smart contract
González’s session, titled “Anatomy of a Smart Contract: concepts, basic structure, examples on EVM and non-EVM”, examined the elements that make up these programs. It covered variables, storage, functions, modifiers, access control and error handling.
The approach explained how those elements relate to each other within a contract and the role they play in defining its behaviour. For people learning blockchain development, understanding that structure helps make sense of the technical decisions behind an application and the way its logic is organised.
The session also compared EVM and non-EVM environments. That distinction showed how smart contract development can use different tools and architectures, and why implementation decisions need to account for the environment in which a program will execute.
From concepts to code
A demonstration in Remix IDE showed the creation and deployment of a contract. This part of the session followed the progression from concepts to an implementation, relating the explanation of the contract’s components to an executable result.
The presentation used applied learning to explain on-chain development. In Metlabs’ work, that understanding connects with building and reviewing systems designed to meet the requirements of a business project, where a program’s behaviour needs to reflect its intended use.
The programme included organisations such as Starknet Foundation, Santander, Chainlink Labs, Solana, BSV Association, Ava Labs, Izertis, Qubic, OpenZeppelin and Vottun. The event therefore brought together perspectives from protocols, development tools, financial services and technology businesses.
The technical dimension of Metlabs’ Madrid participation
The Tech Summit complemented Metlabs’ presence at MERGE Madrid, where Pablo Gómez, CEO and founder, had joined a panel on tokenizing funds and real-world assets.
González’s session introduced the audience to the technical foundations of that activity. Smart contract development forms part of the company’s work, from defining a program’s behaviour to implementing the components required by each project.
