    Ethereum Contract Creator

    Ethereum Contract Creator

    All-inclusive smart contract development and testing tool

    The first application that uses a NFT Software License key, that is a software license key NFT is required from https://bit.ly/3LSCy2J A NFT Software License key is NOT a security. For the first time, the software publisher receives earnings on the resales of the software licenses. Imagine Microsoft being able to earn a percentage of the resales for their Windows licenses sold on ebay? Prior to a NFT Software License, a software company had to rely on advertising, support contracts and one-time sales of their software products, resulting in an iteration of upgrades and new versions. With an NFT Software License, the software publisher can now receive a percentage of the monies from lifetime resales of the software licenses.

    Ethlint

    Ethlint

    (Formerly Solium) Code quality & Security Linter for Solidity

    Ethlint (Formerly Solium) analyzes your Solidity code for style & security issues and fixes them. Standardize Smart Contract practices across your organization. Integrate with your build system. Deploy with confidence! Solium does not strictly follow Solidity Style Guide. The practices it enforces by default are best practices for the community at large. If you’re using vim with syntastic, and prefer to use a locally installed version of Solium (rather than a global version), you can install syntastic local solium to automatically load the local version in packages that have installed their own. Solium does not strictly adhere to Solidity Style Guide. It aims to promote coding practices agreed upon by the community at large. You can specify rules or plugins to apply as command line options. If you specify one, it overrides its corresponding configuration in the soliumrc file.

    Hyperledger Burrow

    Hyperledger Burrow

    A permissioned Ethereum smart-contract blockchain node

    Hyperledger Burrow is a permissioned Ethereum smart-contract blockchain node. It executes Ethereum EVM and WASM smart contract code (usually written in Solidity) on a permissioned virtual machine. Burrow provides transaction finality and high transaction throughput on a proof-of-stake Tendermint consensus engine. Burrow is a fully-fledged blockchain node and smart contract execution engine -- a distributed database that executes code. Burrow runs Ethereum Virtual Machine (EVM) and Web Assembly (WASM) smart contracts. Burrow networks are synchronized using the Tendermint consensus algorithm. A node can detect if its state is corrupted or if a validator is dishonestly executing the protocol. Run a private or public permissioned network. Stakeholders may vote for autonomous smart contract upgrades. Application state is organised in an event stream and can drive external systems.

    Mythril

    Mythril

    Security analysis tool for EVM bytecode. Supports smart contracts

    Mythril is a security analysis tool for EVM bytecode. It detects security vulnerabilities in smart contracts built for Ethereum, Hedera, Quorum, Vechain, Roostock, Tron and other EVM-compatible blockchains. It uses symbolic execution, SMT solving and taint analysis to detect a variety of security vulnerabilities. It's also used (in combination with other tools and techniques) in the MythX security analysis platform. If you are a smart contract developer, we recommend using MythX tools which are optimized for usability and cover a wider range of security issues. The SWC Registry is a community catalog of known smart contract vulnerabilities with detailed descriptions, code samples, and remediations. MythX uses the SWC Registry as its database when scanning smart contracts for security issues.

    Protocol Labs - Retriev

    Protocol Labs - Retriev

    Home of Retriev protocol (by CryptoNet + YOMI)

    Retriev is a Protocol designed by CryptoNetLab and developed by YOMI that allows end users to create retrieval deals with a subset of IPFS providers. It leverages a reliable system of “missed retrieval” penalties that increases confidence in decentralized storage networks. If you want to go deeper on how the protocol works please read our light paper.

    Smart Contract Sanctuary

    Smart Contract Sanctuary

    A home for ethereum smart contracts

    A home for Ethereum smart contracts verified on Etherscan. This is the index repository for the smart contract sanctuary. Bookmark this repo. Chain-specific sub-repos and the index are updated twice a day. Expect a full, recursive check-out to take 2GB+ disk space. Existing repository but submodules never initialized - checkout submodules and update all chain-specific sub repositories. Contains smart contract sources for various networks, grouped by the first two chars of the contract address. A scriptable semantic grep utility for solidity (crunch numbers, find specific contracts, extract data) Semgrep is a fast, open-source, static analysis tool for finding bugs and enforcing code standards at editor, commit, and CI time, and now supports Solidity! A powerful online code search service that can be used to search the sanctuary without cloning.

    solgraph

    solgraph

    Visualize Solidity control flow for smart contract security analysis

    Visualize Solidity control flow for smart contract security analysis. Generates a DOT graph that visualizes the function control flow of a Solidity contract and highlights potential security vulnerabilities. A nice example of piping contract source that is in your clipboard through solgraph, dot, and preview: (Use whatever image previewer is available on your system; Preview.app is available on Mac) You have to have graphviz installed (brew install graphviz) to render the DOT file as an image. Depending on your permissions, you may need to add the unsafe-perm flag.

    web4

    web4

    Web4 is a new way to distribute decentralized apps

    Web4 is a new way to distribute decentralized apps. Deploy a single WASM smart contract to deploy the whole web app. You only need to deploy a single smart contract using WebAssembly to host your app's HTTP backend, static resources, and blockchain logic. There is an HTTP gateway to NEAR blockchain which allows smart contract to handle arbitrary GET requests. Every smart contract on NEAR also gets a corresponding API endpoint which can be accessed through regular HTTP requests. You can load any required data in web4_get by returning list of URLs to preload in preloadUrls field. Note that both JSON and form data are supported. When transaction is processed by server user gets redirected to wallet for signing this transaction.
