BUIDL CTC 2026 Fall - BUIDL For The Real World

Overview

BUIDL CTC 2026 Fall is a virtual hackathon event sponsored by Creditcoin and Credit Labs designed to push the boundaries of cross-chain technology. Teams from around the world are invited to participate across five ecosystem tracks to help expand Creditcoin and demonstrate the Attestcoin Protocol. The event emphasizes open collaboration, innovation, and practical applications that bridge on-chain and off-chain value. The competition is structured to reward bold ideas with a clear path toward real-world impact through the CEIP (Creditcoin Ecosystem Investment Program) fast-track alongside prize incentives. This description compiles concrete details visible on the event page, including theme, timeline, tracks, prizes, and submission requirements, while translating non-English elements where present.

Theme and Attestcoin Protocol

The central theme is the Attestcoin Protocol, which was previously introduced as USC (Universal Smart Contract). Submissions must leverage the Attestcoin Protocol, a decentralized oracle infrastructure that enables smart contracts on Creditcoin to verify cross-chain events and execute logic without relying on centralized oracles or bridges. Teams are encouraged to showcase how this protocol can power trustless cross-chain DeFi, tokenized real-world assets, gaming economies, or verifiable governance. Details and guidance are available through Creditcoin documentation links referenced on the page.

Timeline and Submissions

Submissions open on August 13, 2026, with an online AMA scheduled for the same day. The submission deadline is September 6, 2026, at 23:59 ET. Winners will be announced on September 18, 2026, followed by the CTC Ignition event in Seoul on September 28, 2026. Grand prize contestants outside South Korea may receive flight and hotel accommodations for the CTC Ignition event, subject to organizer guidelines. The event highlights a structured timeline to help teams plan development, submission, and potential travel logistics if selected for in-person components.

Tracks

Five tracks define the competition:

• DeFi: Build lending, trading, liquidity, or yield applications on Creditcoin, demonstrating practical on-chain financial solutions.
• RWA: Tokenize, manage, or finance real-world assets on Creditcoin to bridge off-chain value with on-chain transparency.
• DePIN: Create DePIN applications that use cross-chain data to drive incentives, settlement, or coordination across hardware and sensor networks.
• Gaming: Develop games or gaming infrastructure with in-game economies, asset ownership, and player-driven marketplaces.
• AI: Deploy AI applications that process cryptographically verified cross-chain data to autonomously inform decisions and trigger on-chain actions without centralized oracles.

Prize Pool and CEIP

Total prize pool is $15,000, distributed as $10,000 for the Grand Prize, $3,000 for 2nd, and $2,000 for 3rd. CertiK winner benefits include credits toward a repository audit and three months of Skynet Boost, with CMC listing support noted as not included. The top three teams also proceed through the CEIP fast-track process, an accelerated fundraising pathway led by Credit Labs. This program supports teams with initial investment, engineering and advisory support, and access to partner networks and venture capital connections. The CEIP criteria emphasize meaningful Attestcoin integration, robust project documentation, and team information.

Rules and Submission Requirements

Eligibility requires all team members to have no criminal record or pending cases, not reside in sanctioned countries, and be legally permitted to participate. Projects must demonstrate a meaningful Attestcoin Protocol integration, with working integration code and technical documentation. Submissions should include project information (name, logo, sector, description, Attestcoin integration summary, GitHub URL, deck or whitepaper, and prototype video), team member details (names, emails, social links, bios, roles, residence), and adherence to the original work and testnet deployment requirements. The page also outlines terms and conditions related to accuracy, ownership, and IP rights. Need Help? contacts are provided via official channels, including an email address for team support.

Who Should Attend

This event is aimed at developers, engineers, founders, and teams looking to explore cross-chain use cases, particularly those who want to leverage Attestcoin Protocol to enable trustless cross-chain interactions in DeFi, asset tokenization, and cross-chain gaming or AI-enabled applications.

FAQs

Practical FAQs include questions about eligibility, integration requirements, submission prerequisites, and CEIP benefits, all of which are outlined on the event page and linked Creditcoin documentation. Attendees can reference the timeline, prize distribution, and rules sections to prepare comprehensive submissions and maximize their chances in the competition.
