Backend + blockchain tools for games

Give your game a backend. Add blockchain when you need it.

Bring your existing web or Unity game, or start something new. Add player sign-in, cloud saves, profiles, leaderboards, token access and controlled rewards without building every service yourself.

No invitation or existing API key required. One account; every game stays isolated.

Made for the game you already have

  • Web games
  • Unity
  • AI coding agents
Start with what your game needs

Backend basics first. Blockchain features when you’re ready.

Every feature uses the same game-specific setup. Choose one, test it end to end, then add more.

Player backend

The useful foundation.

  • Player sign-in

    Let players use supported blockchain wallets—including EVM wallets—or optional email sign-in.

  • Cloud saves

    Save progress and settings inside your game’s separately scoped data space.

  • Profiles & leaderboards

    Add player profiles, scores and rankings without operating another backend.

Blockchain features

Useful, with guardrails.

  • Token & NFT access

    Unlock levels, items or experiences using current on-chain ownership.

  • Beginner wallet funding

    Give new players a clear Get ALGO guide for Pera or an existing exchange. Blockmaker shows their exact game wallet without handling card details.

  • Controlled rewards

    Use a dedicated game wallet, explicit spending limits and guarded payouts when you are ready.

Works where you build

One game-specific setup, four ways to use it.

  • Web games
  • Unity
  • Trusted servers
  • AI coding agents
Built for coding agents

Tell your AI what you want to add.

Each game gets a public integration guide with its supported SDKs, public setup details and security rules. Paste that URL into the coding agent that can edit your game.

Safe to paste: the public guide URL.
Never paste: a server key, wallet recovery phrase or .env file.

Example request
“Add Blockmaker player sign-in and a small cloud-save test to this web game. Read the public game guide first, and keep private credentials out of client code.”
How it works

From your game to one working feature.

Blockmaker handles the setup in four clear steps. Start small and keep control of the account and credentials.

See the guided setup
  1. Open secure setup

    Bring an existing game or a new one. Blockmaker takes you straight to the guided first-game setup in the secure admin.

  2. Connect your wallet and add the game

    The wallet owns your reusable account. Add the game details and approve a zero-ALGO ownership proof that is not submitted to the blockchain.

  3. Save the server key

    It is shown once. Store it in a private backend or secret manager—never browser code, a Unity build or AI chat.

  4. Copy the public AI guide

    Give the safe-to-share URL to your coding agent, ask for one feature and test it before adding the next.

Clear security boundaries

Share the guide. Protect the key. Keep games separate.

Blockmaker makes the public and private parts explicit so you—and your coding agent—know what belongs where.

Wallet-owned account

One wallet owns the reusable Blockmaker account. That account can contain multiple games.

Game-by-game isolation

Configuration, credentials, allowed origins and player data are separately scoped for every game.

Clear public/private boundary

The game ID and AI guide can be shared. The server key belongs only in a trusted backend.

Controlled blockchain actions

Rewards need a dedicated game wallet and deliberate limits before they are enabled.

Blockmaker uses logical game isolation within shared infrastructure; it does not claim that every game runs on separate physical hardware.

Bring your game

Start with one feature. Add the rest at your own pace.

Player sign-in and one cloud save make a good first test. No invitation or existing API key required.
