Earn from a $1,700 Prize Pool on Boundless During Southeast Blockchain & Games Week

One live hackathon, three open bounties and an AMA — here's every way to earn and learn on Boundless during Southeast Blockchain & Games Week (SEBGW) 2026.

Southeast Blockchain & Games Week is bringing blockchain builders, gamers, and creators together across Southeast Nigeria this week, and Boundless is running four opportunities alongside it.

As a bronze sponsor and hackathon host for SEBGW, Boundless has also opened a content bounty on the platform.

Boundless × Southeast Blockchain & Games Week

September 16–19 | $200 USDC | Nigeria

Southeast Blockchain & Games Week 2026 is a four-day regional experience running September 16–19 across Southeast Nigeria. There are Build Stations and community hubs in Enugu, Nsukka, Delta, Imo, Abia, Ebonyi, and Anambra, with a final showcase day in Enugu on September 19. Boundless will have a booth at the showcase.

The SEBGW Content Bounty asks you to write an original X thread that tells the SEBGW story while naturally introducing Boundless and how the two connect.

Entries are open now.

Apart from this bounty, there are other opportunities currently live on the platform, including one hackathon and two open bounties. In total, there's currently $1,700 in USDC up for grabs.

Full briefs and resources are available for each opportunity:

Pollar Hackathon: Build on Pollar — $500 USDC
Stellar Vietnam Mid-Autumn Festival — Track 1 — $600 USDC
Stellar Vietnam Mid-Autumn Festival — Track 2 — $400 USDC

Pollar Hackathon: Build on Pollar

September 16–18 | Virtual | $500 USDC

Pollar is a payments SDK for apps, providing wallets, local-currency on/off ramps, KYC, yield through Blend and DeFindex, and agent payments via x402. The SDK is non-custodial and designed to let developers integrate these capabilities with just a few lines of code.

The Pollar Hackathon challenges builders to integrate the SDK into a product that moves real money.

Two Ways to Participate

Build anything on Pollar: Create payments for games, tipping, bill-splitting, freelancer payouts, marketplaces, or any other product where money changes hands.
Take on the flagship challenge: Build the African leg of a payment corridor between Africa and Latin America. Pollar already runs the Latin America side, landing on its live BOB ramp in Bolivia. Your job is to build a path for a user in an African country to fund or cash out through local rails such as mobile money, bank transfers, P2P, or agents, and connect it to Pollar.

The Pollar team is on Telegram throughout the hackathon for SDK help, ramp access, and questions.

Prizes & Timeline

1st place: $250 USDC
2nd place: $150 USDC
3rd place: $100 USDC

The hackathon runs September 16–18, 2026, with winners announced on September 19.

Bounties

Alongside the hackathon, three content and community bounties are live. Here's everything you need to know.

Stellar Vietnam Mid-Autumn Festival: Track 1

August 31–September 26 | $600 USDC

Stellar Vietnam is celebrating the Mid-Autumn Festival by introducing the community to projects building across the Stellar ecosystem in Vietnam. Track 1 is the easy-entry option: it's a lucky draw rather than a judged competition.

To qualify, you just need to:

Like and repost the official campaign announcement post on X.
Follow all 10 participating Stellar Vietnam project accounts on X.

12 winners are drawn at random from all qualifying entries, and each winner receives $50 USDC.

Stellar Vietnam Mid-Autumn Festival: Track 2

August 31–September 26 | $400 USDC

Track 2 is a content and quality-based competition. Winners are selected based on the quality of their post, as well as its reach and engagement.

Create and publish an original post about the Stellar Vietnam ecosystem. Suggested angles include:

A research piece on the Stellar Vietnam ecosystem.
A breakdown of Stellar Vietnam's achievements this year.
Any other original content that helps people understand what's happening in the ecosystem.

The format is flexible — thread, standalone post, article, or video — as long as it's published on X, tags @VN_Stellar, and is original human-driven work rather than copy-pasted or unedited AI output.

Both Mid-Autumn Festival tracks close on September 26.

Stellar Vietnam is hosting a live AMA on their X account on Friday, September 18.
