BIG Token

BIG is live. We’re building a platform that makes everyday things — like rent, leases, and payments — simpler, clearer, and more fair. You won’t need to “know blockchain” to use it. The tech works quietly in the background. We’ll share progress as we build.

Weekly Update – Strengthening Compliance & Security Foundations on Casper Frontend • Validated full ICO page functionality with thorough end-to-end testing • Researched CSPR.click integration for smooth user authentication (social login + self-custodial experience) • Analyzed potential partnership platforms to expand our ecosystem Contracts • Continued integration of ERC-7943 into the NFT contract for robust RWA compliance • Added advanced security & regulatory features: – Whitelisting for minting and transfers (enables verified/KYC users) – Asset freezing to restrict transfers during legal disputes – Forced transfers by authorized admins (supports seizures, wallet recovery, and regulatory compliance) – Wrapped transfer logic to automatically enforce whitelisting and freeze checks – Switched to the Access Controls module for clear separation of duties (e.g., dedicated roles for freezing, whitelisting, minting/burning) We’re also actively coordinating with Halborn on our upcoming security audit. To maximize effectiveness and cost efficiency, we’ve decided to bundle in three additional contracts the marketing contracts for real estate buying/selling and two metadata contracts ported from EVM — before the review. This avoids duplicate work and ensures everything is audited together. As a result, we’re adjusting our timeline and expect the ICO to move forward in approximately three weeks once these integrations and the audit scope are fully aligned. In the meantime, testnet activity continues smoothly. Want to experiment with transactions? Grab test CSPR here: testnet.cspr.live/tools/faucet Quick note: The recent Vercel incident had no impact on us — our code isn’t hosted there, and we’re only using test keys. Everything remains normal on our end. These deliberate steps are making BIG Token one of the most compliance-ready and audit-conscious projects building real-world asset tokenization on Casper. Quality over speed. How do you feel about projects that take the extra time for proper security and compliance? Worth it, or would you prefer faster launches?

Working with @HalbornSecurity shows a serious credibility signal. Keep up the good work. Stay loyal to utility 🤞

Contracts • Deployed remaining contracts: Lease, Escrow, NFT, Roles • Researched and responded to mockup phased architecture plan • Fixed bug where staking and vesting data were getting out of sync The foundation keeps getting stronger every week. More updates soon 👀 What are you most excited to see next? Drop your thoughts below! #BIGToken #CasperNetwork #LeaseFi #RWA 4/4

Backend • Continued building the blockchain indexer service • Fixed data correctness issues in release schedule calculations, reward snapshot monotonicity, and ICO schedule filtering by active timestamp • Strengthened security by masking database credentials in scripts and adding auth middleware to protected routes • Expanded integration test coverage for ICO progress capping, staking idempotency, unbonding, and earnings decimal precision 3/4

🚀 BIG Token Weekly Update We’re making solid progress across the stack — and we’re now roughly 1–2 weeks away from sending the initial code to @HalbornSecurity for the 3rd-party audit and getting their estimate. Infrastructure first. Precision over hype. Real utility building on @Casper_Network. #BIGToken #CasperNetwork #Web3 #RWA

🚀Next phase: Marketplace module + expanding the full application. Audit discussions kicking off soon, decentralized hosting explorations underway, and more updates coming. Private sale testnet is live and ready for you: leasefi.vercel.app/icoDive in, test the flows (spend or receive toggles, check vesting/staking), explore the connected features, and share your thoughts—your feedback directly fuels the roadmap. Infrastructure first. Real utility building on@Casper_Network. Think #BIG #LeaseFi #CasperNetwork #RWA 4/4

The full ICO experience page is now operational on testnet: smooth, integrated, and user-friendly. This milestone nails the foundation for fair, interoperable token mechanics and long-term alignment. Grateful for the collaboration and trust—building something solid. 3/4

🚀 Milestone 2 Locked In: LeaseFi Core Infrastructure Delivered! 📷Huge progress on LeaseFi (powered by $BIG on @Casper_Network): Milestone 2 is officially complete! All core components built, rigorously tested, and fully integrated—delivering transparent, end-to-end RWA infrastructure with full ownership and battle-tested connectivity. Precision over hype, always. 1/4

🚀Looking ahead: Initial touchpoint meeting with @HalbornSecurity tomorrow for security audit discussions—proactive step to ensure bulletproof contracts. Also exploring @akashnet for decentralized network hosting to boost resilience and align with our transparency ethos. Private sale testnet still live: leasefi.vercel.app/ico Jump in, test the new purchase flows, check your vesting/staking views, and drop feedback. Your input drives real progress. Think #BIG #CasperNetwork #RWA 5/5

Frontend: Revamped the purchasing card component—now with clear toggles: "I want to spend" (enter USDT/USDC amount → auto-calcs BIG tokens) or "I want to receive" (enter BIG amount → shows required USDT/USDC). Backend integration is live for transaction history, balances, vesting schedules, and staking info. Smoother, more intuitive UX coming together fast. 4/5
