DINO
Shared Distribution & Liquidity Layer for T-REX
Dino is the onchain distribution and market infrastructure of the T-REX ecosystem. It provides a shared set of smart contracts that any issuer, distributor, broker-dealer, or dApp builder can plug into to distribute and trade ERC-3643 (T-REX) tokens.
Instead of every project deploying its own isolated subscription forms and OTC order books, Dino runs on a shared infrastructure (the T-REX Ledger). This turns fragmented primary and secondary flows into a common liquidity pool, where all participants benefit from the same rails and network effects.
What Dino Does
At a high level, Dino provides three building blocks:
DinoFactory – Deploys and wires Dino contracts (Primary & Secondary) for a given ERC-3643 token, with standardized roles, fees, and permissions.
DinoPrimary – Handles onchain subscription and redemption flows for T-REX tokens in the primary market (investors subscribing to new tokens or redeeming them with the issuer).
DinoSecondary – Handles onchain trading intents in the secondary market (investors posting offers to buy or sell existing T-REX tokens).
Together, they form a single onchain venue where compliant primary flows and secondary trading can coexist for any ERC-3643 token connected to the T-REX Ledger.
Dino Primary: On-Chain Subscriptions & Redemptions
DinoPrimary is the primary market layer for T-REX tokens:
Issuers (or their distributors) can open subscription windows and let qualified investors subscribe onchain using approved payment tokens (e.g. stablecoins).
The same rail can be used for redemptions, allowing investors to sell tokens back to the issuer under predefined rules.
All flows are compliance-aware, leveraging the ERC-3643 identity and eligibility checks (Identity Registry, ONCHAINID, etc.).
For the user, this can look like a simple “Invest” / “Redeem” button in a dApp or platform UI. Under the hood, all issuers use the same DinoPrimary infrastructure, which:
Standardizes subscription and redemption logic.
Applies ecosystem fees in a predictable way.
Ensures that investor qualification and token compliance are enforced at the contract level.
The result: repeatable, interoperable primary flows for any compliant RWA, instead of one-off bespoke implementations per issuer.
Dino Secondary: Shared Intent-Based Liquidity
DinoSecondary is the secondary market layer:
Investors can publish offers (intents) to buy or sell a given T-REX token against another token (typically a payment token).
Other participants can take those offers, fully or partially, enabling peer-to-peer trading.
Offers are managed onchain with expiry, pruning, and compliance checks built in.
Because DinoSecondary is shared:
Any broker-dealer, platform, or dApp can plug into the same pool of offers.
Liquidity doesn’t get siloed inside a single interface, it’s aggregated at the contract level.
The same fee and compliance framework applies to all trades, simplifying integrations.
This creates a common secondary liquidity network for ERC-3643 tokens, rather than fragmented OTC channels scattered across different systems.
Running on the T-REX Ledger: Shared Infrastructure by Design
Dino contracts are deployed on the T-REX Ledger, which acts as the reference chain for compliance and market infrastructure across the ecosystem.
Because DinoPrimary and DinoSecondary are shared contracts on this common ledger:
Any compliant ERC-3643 token can attach to the same primary and secondary rails via the DinoFactory.
Distributors, broker-dealers, custodians, and platforms can integrate once and access all Dino-enabled tokens.
New apps (e.g. white-label platforms, bespoke institutional portals, wallets, or aggregators) can reuse the same contracts and liquidity instead of rebuilding their own infrastructure.
In other words, Dino is not a single app, it is the onchain market layer that all T-REX-compatible apps can build on.
Who Is Dino For?
Dino is designed to be used by:
Issuers & Fund Managers Use DinoPrimary to run compliant onchain subscriptions and redemptions for their RWA programs.
Distributors, Broker-Dealers & Market Operators Plug into DinoPrimary and DinoSecondary to distribute products and provide liquidity without reinventing the rails.
Platforms & dApp Builders Build investor-facing experiences on top of shared infrastructure, benefiting from common standards, fees, and compliance behavior.
Investors Interact through any connected dApp to subscribe, redeem, and trade T-REX tokens, while always benefiting from the same underlying onchain logic.
Dino in the T-REX Apps Stack
Within the broader T-REX ecosystem:
T-REX Engine exposes APIs to interact programmatically with Dino contracts.
T-REX Platform and dedicated dApps (DINO Primary dApp, DINO Secondary dApp) provide investor-facing UIs on top of these contracts.
Dino itself is the neutral, shared smart contract layer that all of these applications use for distribution and trading.
