Build with Brickken: a 6-week programme on tokenization + agentic infra ($2K prize pool)

TL;DR
We're running a 6-week developer programme from Aug 7 to Sep 17. Build a working tokenization or agentic workflow against Brickken's sandbox using the REST API, CLI, MCP server, or Brickken Skill.

Five prizes
$2,000 pool
Deadline Sep 17 at 23:59 CET.

Hey DEV, I'm Stefan, Social Media Manager at Brickken. Disclosure upfront: this is a Brickken programme and I work there.

If you've been experimenting with x402, ERC-8004 identity, MCP servers, or tokenized real-world assets and want a concrete brief to build against, here's one with real infra and a prize pool behind it.

What you can build with

Brickken exposes four surfaces you can mix and match:

REST API for institutional tokenization workflows (issuance, transfers, compliance, lifecycle).
CLI, chain-agnostic, for scripted deploys and agent-driven flows.
MCP server so any MCP-compatible client (Claude, GPT, custom agents) can call Brickken as a tool.
Brickken Skill for agent frameworks that consume Skills directly.

On top of those, the campaign gives you a testnet-only playground for:

x402 for per-call USDC payments over HTTP
ERC-8004 for on-chain agent identity
ERC-7943 (uRWA), the tokenized real-world asset standard co-authored by our Head of Blockchain
ERC-8226 (RAMS) for regulated agent mandates
Chainlink CCIP for cross-chain flows

Sandbox, not mainnet

All work runs against:

https://api.sandbox.brickken.com/
https://dapp.sandbox.brickken.com/

Testnet faucet assets only. No real USDC, no bridging, no mainnet keys.

Target networks depend on which challenge you're building for:

Agentic challenge: Ethereum Sepolia or Base Sepolia (x402 settlement is available on both)
API-key builds: Polygon Amoy is also supported
RAMS operations: Ethereum Sepolia only for now

Full API reference and quickstart at docs.brickken.com.

What we're looking for in a submission

Working implementation. Not a mockup, not a slide deck. It has to actually run.
Public repo, or a private one with a Brickken reviewer added, plus a README on what it does, how to run it, and which surfaces (REST, MCP, CLI, Skill) and methods you called.
Real, verifiable calls against the Brickken sandbox. Your submission must include the chainId and the transaction hashes your build produced. We verify claimed usage against our own transaction and payment records.
2 to 3 minute demo recording, or a live URL we can hit.
An EVM wallet address for potential reward payout.

If you use AI tools in your build, disclose them in the README. AI assistance is fine; wholesale generation without meaningful developer contribution is not.

How to submit

Both channels are required for your entry to count:

Post in the Discord #submit-your-builds channel
Email build@brickken.com

Deadline is the same for both: Sep 17 at 23:59 CET.

How it's judged

Reviewed by the Brickken engineering team on four criteria:

Technical execution
Depth of Brickken infrastructure use
Originality of the use case
Clarity of documentation

Decisions are final.

Prizes

$2,000 pool across the top 5 submissions, regardless of which challenge you build in. One deadline, five payouts.

A few build ideas to prime the pump

Not requirements, just angles that fit the stack well:

An MCP server that lets a chat client issue and transfer tokenized assets against sandbox
An agent that discovers itself on ERC-8004, sells a data or compute service, and gets paid per call via x402
A CLI wrapper that deploys an ERC-20 and an ERC-7943 uRWA in one command across two testnets
A CCIP-powered cross-chain redemption flow for a tokenized asset
Anything that composes at least two of REST / CLI / MCP / Skill in a workflow that would look ridiculous to build without automation

How to join

Read the brief: https://landing.brickken.com/build-with-brickken?utm_source=dev.to&utm_medium=organic&utm_campaign=b2b_buildcampaign
Request a sandbox API key
Join the Discord for build support and submissions
Ship before Sep 17, 23:59 CET

Ask me anything in the comments. If your question is more of a "how do I call X endpoint," docs.brickken.com or the Discord support channel will get you a faster answer than I can.

Good luck. Curious to see what you build.
