Salto X raises 5.2 mln EUR to give contributors fair company upside internationally

Most of the founders, who have distributed teams know the pain of giving out equity. Different laws in different jurisdictions, taxation and employment rules. And the pain only increases, when founders try to give equity to non-employees: contractors, advisors, community and any other type of gig workers. It seems so obvious that old-school stock options just do not fit into the future of work. And we are here to change that with Salto X - web3 alternative to stock options in Europe.

How events in Solidity work, and why are they needed

Kristaps Grinbergs

Events in Solidity programming language help inform when something has happened in the smart contract. Parties like a web frontend, data gathering tools, and more can listen to specific events and react accordingly. In this post, we will dig deeper into Events and how to use them when developing smart contracts on Ethereum-like blockchains.

The Story behind Mapping in Solidity

Kristaps Grinbergs

Mappings in Solidity programming language play a significant role. These are hash tables that can have a key and value. When we use them, there are some caveats, especially from other programming languages. Let's explore them in this article.

Mastering Arrays in Solidity

Kristaps Grinbergs

Arrays in Solidity programming language can hold primitive data types like integers, boolean, and string. An array can be initialized with a fixed or dynamic size. If we compare them to other more advanced programming languages, there are pretty limited functions available to work with arrays. Despite that, we can add, remove, get the size of the array, and more.

Accessibility and visibility in Solidity

Kristaps Grinbergs

Solidity language allows specifying accessibility for contract functions and state variables. That will enable us to set constraints on constructing the smart contract and whether other contracts or addresses can access the data. Contract state variables and functions have a slight difference that we're going to check out. I want to mention that accessibility and visibility are different things in blockchain development context.

Solidity for Swift developers: File Structure and Functions

Kristaps Grinbergs

Solidity is an object-oriented language to write smart contracts that can be deployed on the blockchain, for instance, Ethereum. The syntax is similar to Javascript, but on the other hand, semantics is closer to C++. We will dig into Solidity language structure and functions from a Swift developer's perspective.
