Team DOI

We are proud to announce that Digital Oro International has completed a successful smart contract audit with @hackenclub. The full report is available for review, reinforcing our commitment to the highest standards of security and compliance. Our priority is delivering fully audited smart contracts for real-world assets, ensuring corporations and investors can trust the integrity of our infrastructure. We are pioneers in smart contracts and real-world asset tokenization. Contact us to get a walkthrough linktr.ee/digitalorointe…

Summary: We use ERC-721 because it provides: ✔️ non-fungible, one-per-member access ✔️ clear ownership and transfer logic ✔️ predictable governance ✔️ clean integration with staking, referrals, payouts, and real estate contracts. It is the correct standard for a membership-based system where access and privileges must be tied to individual, verifiable, non-divisible positions.

4. It integrates cleanly with DOI’s smart contract structure Many parts of the system rely on identifying which member is interacting, not just how many tokens they hold. ERC-721 simplifies: A. staking rights B. referral rewards C. lock mechanics D. payout eligibility E. membership verification Each contract can reference a specific membership token ID and apply the correct logic.

Why DOI Uses ERC-721 for Membership Instead of ERC-20 and Why it Matters? When designing the DOI Gold membership, we evaluated multiple token standards. We chose ERC-721 because a membership is a single access credential, not a divisible or interchangeable asset. ERC-721 enforces this technically: each token represents one membership with specific rights, and the system can track, verify, and apply rules to each token individually. Here’s a clear breakdown:

DOI recently completed a full smart contract audit with @hackenclub. They analyzed: A. Contract logic B. State transitions C. Access control D. Payout scheduling E. Staking and lock mechanics F. Referral calculations G. Edge cases and failure conditions H. Security vulnerabilities What the audit confirmed: ✔️ Contract logic behaves as expected ✔️ Functions are isolated and clearly scoped ✔️ Rights and permissions are properly restricted ✔️ Payout and staking flows follow the intended rules ✔️ No critical vulnerabilities were found ✔️ The system is predictable and auditable Why this matters 1. For members: Your membership rights, staking logic, and payouts are backed by verified contract behavior. 2. For partners: You can rely on a transparent, predictable, and security-reviewed architecture, not untested code. 3. For the ecosystem: The audit strengthens the technical foundation as we prepare for platform expansion and increased activity.

5. Lifetime Gold Membership as the Access Layer DOI uses a membership model that grants: ✔️ Access to property-backed yield pools ✔️ Global rental discounts ✔️ Ecosystem utilities ✔️ a growing network of properties and services

4. Unified Platform DOI operates through a single platform that connects every part of the ecosystem within one interface. Members can access investment opportunities, track construction progress, manage their benefits, and book their stays through a unified dashboard. The platform integrates: A. Real estate portfolio, showing available properties B. Yield pools, where Gold members stake into real estate-backed contracts C. Travel & lifestyle benefits, including discounted rates and member-only access D. Ecosystem partners, including tech integrations, hospitality operators, construction suppliers, and service providers E. Membership and referral systems, tied to the DOI_Gold and referral contracts

What Makes DOI Structurally Unique 1. Debt-Free Real Estate Backbone Most real estate ecosystems rely on leverage. The entire model is built on owned, unleveraged, income-generating properties. This reduces risk and creates a stable asset foundation.

As we expand into new regions, building a strong foundation is our priority. In Phase 1, we are establishing the structure that protects our members, partners, and the long-term integrity of the ecosystem. This involves finalizing the compliance rails, audit requirements, licensing steps, and platform upgrades to ensure the entire operation is stable, audited, and scalable. This framework enables every property listing, partnership, and on-chain component to plug seamlessly into a user-friendly platform that unlocks access to our growing ecosystem. Phase 1: Compliance & Launch ✔️ Complete Hacken audit — Completed ✔️ Release the updated platform — Launching soon ✔️ DOI Community & Ecosystem Growth — In Progress ✔️ Begin token licensing process — In Progress …and we keep building. Each milestone we complete strengthens confidence in our foundation and demonstrates to our community dependable execution. Take a sneak peek at our updated platform. Launching soon

Our system reduces build times by up to 40%, eliminates cost overruns, and positions DOI as a key supply partner for developers seeking speed, consistency, and high-quality execution. This is a real-world engine, and revenue reflects it: ✔️ Modular construction and development contracts ✔️ Global materials sales from our logistics park ✔️ Full-service support for developers and operators

Modular Construction: Speed, Precision, and Global Access DOI Construction is a full-service modular construction firm and global materials distributor. We deliver prefabricated steel-frame villas and custom residential or commercial projects based on any plan or design, shipped worldwide with AAA-standard finishes.

From here, our roadmap follows a phased expansion strategy, beginning with our existing operating properties and then moving into LATAM, Europe, and Africa with additional collateral and regional white-label partners. Phase 1: Compliance & Launch ✔️ Complete Hacken audit ✔️ Release the updated platform ✔️ DOI Community & Ecosystem Growth ✔️ Begin token licensing process Phase 2: Ecosystem Expansion Phase 2 starts by launching with our current operating properties, including: ✔️ 45 units of Apartment Suites ✔️ 10 Tulum Town Villas ✔️ Zama Penthouse ✔️ Logistic Park Property We then bring new international properties into the ecosystem in the following locations: ✔️ Zipolite, Mexico ✔️ Costa Rica ✔️ Portugal ✔️ Zanzibar ✔️ Cape Town ✔️ Launch first white-label partner ✔️ Expand Web3 partnerships Phase 3: Members Onboarding & Global Integration ✔️ Members events & onboarding ✔️ Continue with International properties expansion ✔️ Ecosystem growth onboarding Institutional, tech, and suppliers partnerships We’re now opening conversations with partners who align with our asset-backed, compliance-led model across real estate development, modular construction, and specialized supplier networks. If you’re building in these regions or are interested in integrating innovative tech models, let’s explore potential collaboration. Book an exploratory call calendly.com/digitalorointe…

DOI Global Expansion Roadmap: From Mexico to LATAM, Europe, and Africa We chose Mexico as our starting point for a reason. Mexico combines fast-growing tourism, cost-efficient construction, and clear pathways for asset-backed, compliance-oriented models, which makes it an ideal base for DOI’s CeFi membership ecosystem and modular construction division.

Members can choose one or multiple real estate properties and invest any amount they prefer. Each investment earns a fixed 12% APY, with funds locked for 12 months before they can be withdrawn or reinvested. There is no leverage, no mortgages, no third-party loans, and no rehypothecation of member funds. Access to these yield pools is available exclusively to verified Gold Members who have completed KYC and signed the Member/Shareholder Agreement.

Once you become a Gold Lifetime Member of the DOI ecosystem, you will have a series of benefits and investment options to choose from. The 12% fixed annual yield (1% monthly) is embedded within a specific architecture: yields are collateralized by fully owned, debt-free properties owned by DOI with a BTC reserve acting as an additional liquidity and risk-mitigation buffer. We enforce a strict 1:1 collateralization rule, ensuring that the total member allocation in each pool never exceeds the professional appraised property value behind it.

DOI's Annual 12% Collateralized Yield Model “12% annual yield” only matters if you understand how it’s structured and how the model itself is built for risk management.
