    GraphQL Scalars

    GraphQL Scalars

    A library of custom GraphQL Scalars for creating precise schemas

    GraphQL is a wonderful new approach to application data and API layers that's gaining momentum. However, for all of GraphQL's greatness, it is missing a couple of things that we have (and you might) find very useful in defining your schemas. Namely GraphQL has a limited set of scalar types, and we have found there are some additional scalar types that are useful in being more precise in our schemas. Thankfully, those sharp GraphQL folks provided a simple way to add new custom scalar types if...

    A toolbox for zkSNARKs on Ethereum

    ...One particular family of ZKPs is described as zero-knowledge Succinct Non-interactive ARguments of Knowledge, a.k.a. zkSNARKs. zkSNARKs are the most widely used zero-knowledge protocols, with the anonymous cryptocurrency Zcash and the smart-contract platform Ethereum among the notable early adopters. Ethereum runs computations on all nodes of the network, resulting in high costs, limits in complexity, and low privacy. zkSNARKs have been enabling to only verify computations on-chain for a fraction of the cost of running them, but are hard to grasp and work with.

    TypeChain

    TypeScript bindings for Ethereum smart contracts

    TypeChain generates only TypeScript typings (d.ts) files, if you're looking for "opinionated", "batteries included" solution check out our new project: eth-sdk. It generates typesafe, ready to use ethers.js wrappers and uses etherscan/sourcify to automatically get ABIs based only on smart contract addresses. Under the hood, eth-sdk relies on TypeChain. Interacting with blockchain in Javascript is a pain. Developers need to remember not only a name of a given smart contract method or event but also it's full signature. This wastes time and might introduce bugs that will be triggered only in runtime. TypeChain solves these problems (as long as you use TypeScript). ...
