Tintero | Protocol

Tintero is an asset-backed security (ABS) lending protocol that provides liquidity in exchange for tokenized receivables (or any negotiable instrument). These negotiable instruments are represented as NFTs whose identifier is the hash of a document representing the underlying asset.

Investors can deposit their assets in a Tintero vault (e.g USDC) and receive shares in exchange. These shares are later allocated towards funding loans approved by a vault manager.

On the other side, asset originators can write loans, leases, or any other kind of Real World Asset (RWA) and tokenize them using Plumaa ID. These tokens are used as collateral to request a loan from a Tintero vault. If the manager approves the loan, the loan is funded and the principal is transferred to a beneficiary address.

Assets are represented through the Endorser contract, an ERC721 token that uses a document hash as a token id. It complies with data preservation requirements and a non-interrupted chain of endorsements under Mexican commercial and debt instruments law by indexing the chain of transfers (i.e. endorsements) whose signatures are non-repudiably linked to the user's address when transferring via Plumaa ID.

The content of documents remains private since the system only track hashes.
