Building a scalable cross-chain DeFi vault infrastructure with ERC-7540 and automated yield management
About The Project
The project was designed to help blockchain projects distribute tokens, rewards, and promotional incentives through a secure and verifiable claim process. Instead of relying on manual verification or vulnerable claim forms, the platform introduced automated ownership verification, wallet validation, and campaign management capabilities to ensure that rewards reached legitimate recipients.
The solution supports multiple claim campaigns, wallet verification workflows, token eligibility checks, and user notifications while providing a streamlined experience for both campaign operators and participants.

Key Challenges
Preventing fraudulent reward claims
One of the biggest challenges was verifying that users actually owned the blockchain addresses they were claiming rewards for. Without proper validation, bad actors could submit fraudulent claims and exploit token distribution campaigns.
Reducing user mistakes during registration
Users frequently make mistakes when entering wallet addresses, selecting blockchain networks, or submitting claim information. These errors can lead to failed distributions and support overhead for campaign operators.
Balancing security with accessibility
Traditional wallet verification methods often require technical knowledge, gas fees, and wallet interactions that can discourage participation. The platform needed to create a process that remained secure without becoming overly complex.
Supporting privacy-conscious participants
Many participants wanted to verify ownership while minimizing on-chain activity and protecting the relationship between their various blockchain identities. The platform needed to provide alternative verification paths while maintaining trust.
Managing large-scale token distributions efficiently
Token distribution campaigns often involve thousands of participants across multiple blockchain networks. Managing verification, eligibility tracking, and reward distribution manually would not scale effectively.
Our Solution
Multi-layer wallet ownership verification
The platform implemented a verification mechanism where users proved ownership of blockchain wallets through controlled transactions and validation workflows. This significantly reduced fraudulent claims while maintaining transparency.
Signature-based verification workflows
To improve privacy and reduce blockchain transaction requirements, the system introduced message-signing workflows that allowed users to prove ownership without sending on-chain transactions. This reduced friction while preserving security.
Automated campaign management system
The platform centralized campaign creation, participant enrollment, claim tracking, wallet verification, and reward processing into a single workflow. This reduced operational complexity for campaign operators.
Flexible claim tracking architecture
A unique claim identification system was proposed to allow participants to retrieve claim information even when wallet connections were unavailable. This ensured traceability while supporting multiple verification models.
Scalable multi-chain distribution infrastructure
The solution was designed to operate across multiple blockchain ecosystems while optimizing distribution costs and simplifying campaign participation. This enabled efficient scaling for future token launches and reward programs.
The Result
Improved claim authenticity
The wallet ownership verification framework ensured that rewards were distributed only to verified participants, improving campaign integrity and trust.
Enhanced user experience
Participants could follow guided claim workflows, reducing confusion and minimizing errors during registration and verification.
Increased privacy and flexibility
By supporting transaction-based, signature-based, and lightweight verification methods, the platform accommodated a wide range of user preferences and security requirements.
Created a scalable foundation for future campaigns
The modular architecture provided a reusable framework for future reward programs, token launches, and community incentive campaigns across multiple blockchain networks.
