Subscriptions push activity to you as it happens, and this covers setting th… | | [Query Blocks and Transactions](/app/query-blocks) | Skill | Most Ethereum work starts with reading: what happened in this block, did this transaction go through, what does this address hold. This cov… | | [MUD Quickstart with Nethereum](/app/mud-quickstart) | Skill | MUD puts structured application data on-chain, and building against it from .NET means bridging two worlds.

EIP-7702 lets you attach contract logic to that plain addr… | | [EIP-712 Typed Data Signing with Nethereum](/app/eip712-signing) | Skill | Some signatures are meant to be readable - the wallet shows a person the fields they are agreeing to, not a wall of hex.

This lets you read and act on t… | | [Built-in Contract Standards](/app/built-in-standards) | Skill | Most contracts you touch follow a standard shape, and rewriting bindings for each one is wasted effort. This gives you ready typed services… | | [Blockchain Data Indexing](/app/blockchain-indexing) | Skill | Asking a node about past activity is slow and awkward, and it forgets nothing helpfully. This copies blocks, transactions, logs and token a… | | [Blockchain Explorer](/app/blockchain-explorer) | Skill | When you are working on a chain you often need to see what is actually on it, and building that view yourself is a project of its own. This… | | [SIWE Authentication in Blazor](/app/blazor-authentication) | Skill | You want people to log into your web app with their Ethereum wallet instead of a username and password.
