Tintero is a set of smart contracts to which we refer to as the protocol. The protocol is composed by 4 smart contracts from which 2 are core to each Tintero pool and the other 2 can be considered accessories:

​
Pool contracts

TinteroVault

An ERC-4626 vault with extra features to manage capital delegations and loan funding. It deploys instances of the TinteroLoan contract and is managed by the AccessManager contract.

TinteroLoan

A state machine that manages the lifecycle of a loan structured as a series of payments, each one collateralized by an ERC-721 token that represents a discounted legally-binding obligations.

​
Accessory contracts

  • AccessManager: A contract that manages roles and permissions for all contracts in the Tintero protocol.
  • Endorser: An ERC-721 contract provided by Plumaa ID that represents a legally-binding obligation. Any other ERC-721 contract can be used as a collateral for each loan, independently of which vault it belongs to.
