fusogen

What it does

From the project README:

Fusogen is a platform designed to facilitate mergers and acquisitions (M&A) like actions for decentralized autonomous organizations (DAOs). As decentralized communities and blockchain-based entities grow, there is a growing need for DAOs to consolidate resources, collaborate, and merge effectively—much like traditional businesses. However, DAOs operate under different rules, relying on smart contracts and decentralized governance, so traditional M&A processes don’t apply. Fusogen addresses this gap by providing a framework to streamline the merging of DAOs, allowing them to combine assets, gov

Dapp: devnet deploy pending

⏳ Devnet deploy pending — goes live when the devnet wallet is topped up. This fork's own dapp is not deployed yet, so there is no program address or transaction to show. It is queued in dapp-queue.txt; once devnet SOL is available it is deployed, exercised with real devnet transactions, and this section switches to the live dapp at /dapps/fusogen/. Until then, the lesson and step-by-step guide below are complete, and you can run it locally with the commands below.

How to run, build and test

These commands come from the repo's own manifests (package.json scripts, Anchor.toml, Cargo, go.mod, Makefile). Check the README for prerequisites and environment variables.

Directory	Command	Runs
`.`	`npm run dev`	nx serve web
`.`	`npm run build`	nx build web
`anchor`	`anchor build`	compile programs and generate IDLs
`anchor`	`anchor test`	local validator + test suite
`anchor`	`anchor run test`	../node_modules/.bin/nx run anchor:jest
