# Glossary

| Term                           | Definition                                                                                                                                                                                    |
| ------------------------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Amortisation**               | The process of reducing outstanding principal with each payment. Each installment contains an interest component and a principal component, split separately for each tranche.                |
| **Allowlist**                  | A list of approved investor addresses for permissioned vaults. Managed by the Pool Manager. Independent of the protocol-wide compliance gate.                                                 |
| **Arrears**                    | The deficit carried forward when a waterfall bucket isn't fully paid in a period. Cleared, in bucket order, before the next period's own dues.                                                |
| **Basis Points (bps)**         | A unit of measurement: 1 bps = 0.01%. An interest rate of 1000 bps = 10%.                                                                                                                     |
| **Borrower**                   | A business that receives a loan through a Trilobyte vault and repays through incoming revenue. Can never be the same address as the vault's manager.                                          |
| **Cancelled**                  | The lifecycle phase reached when a vault misses its funding or approval deadline. Investors pull their own refund via `claim_refund`.                                                         |
| **Cash Pool**                  | The residual left after a repayment clears the six-bucket waterfall. Withdrawable by the borrower, blocked while behind on payments.                                                          |
| **Collateral (manager)**       | Tokens staked by a Pool Manager as guarantee, anchoring the vault's junior tranche. Locked when a vault is created, released on repayment, slashed (into the recovery pool) on default.       |
| **Collateral (borrower)**      | An optional real-world asset or other token the borrower pledges into the shared escrow. Verified at disbursement, released on repayment, seized ahead of manager collateral on default.      |
| **Collateral Asset Whitelist** | A Globals list of assets eligible to be posted as manager or borrower collateral — separate from the list of assets that can be lent.                                                         |
| **Compliance Gate**            | An optional, Globals-configured contract (`is_allowed(who, action)`) checked before investing, borrowing, and vault creation. Unset means every check passes.                                 |
| **Concentration Floor**        | The level of protocol-wide outstanding principal below which borrower/manager share caps don't yet apply, so the protocol's first loans aren't blocked.                                       |
| **Covenant**                   | A loan-level condition beyond repayment itself — the cash-pool lock while a borrower is behind, and an optional reporting-cadence requirement.                                                |
| **Credit Limit**               | The maximum total outstanding principal a Pool Manager can have across all active vaults. Set by the Operations Admin.                                                                        |
| **Debt Token (tVLT)**          | Non-transferable SEP-41 fungible token minted 1:1 (net of the protocol fee) with an investor's deposit. Tranche identity is tracked separately, not by the token.                             |
| **Default**                    | Triggered when a borrower fails to repay within the grace period. Results in manager collateral slashing, any borrower pledge seizure, and delinquency flagging.                              |
| **Delinquency**                | A flag applied to Pool Managers whose vaults have defaulted. Blocks new vault creation until cleared by an Operations Admin.                                                                  |
| **Exposure Cap**               | A protocol-wide limit on a single borrower's or manager's outstanding principal as an absolute amount or a share of total outstanding, enforced by the Factory at vault creation.             |
| **Factory**                    | Smart contract that deploys new vault instances. Validates parameters, leverage, exposure caps, and manager eligibility before deployment.                                                    |
| **Finalized**                  | The single terminal vault phase, reached from FullyRepaid, Cancelled, or Defaulted once every party has claimed. No further actions possible.                                                 |
| **Globals**                    | Smart contract managing protocol-wide settings, roles, fees, both asset whitelists, manager collateral, and exposure tracking.                                                                |
| **Governor**                   | The protocol administrator. In production, governance actions are routed through the Timelock for delay enforcement.                                                                          |
| **Grace Period**               | Configurable window (default 30 days) after a missed payment before default can be triggered.                                                                                                 |
| **Investor**                   | An address that deposits funds into a vault's senior or junior tranche and earns yield from borrower repayments.                                                                              |
| **Junior Tranche**             | The first-loss investor layer, anchored by the manager's own collateral. Paid last, loses first, earns a spread.                                                                              |
| **Junior Spread**              | The share of senior's interest paid to junior each period as compensation for absorbing losses first.                                                                                         |
| **Late Fee**                   | A governed penalty (default 18% p.a.) applied by the Pool Manager when a payment is overdue, collected through the senior/junior arrears buckets.                                             |
| **Leverage Ratio**             | How large senior capital may be as a multiple of junior. Determines the size of each tranche; capped differently for collateralized vs. uncollateralized loans.                               |
| **NAV Write-Down**             | A linear, view-only markdown of a tranche's outstanding-principal value as a loan falls further behind, before formal default. Reverses if the borrower catches up.                           |
| **Operations Admin**           | Protocol role responsible for approving/removing pool managers, setting credit limits, clearing delinquency, and updating settings/fee (not timelocked).                                      |
| **Permissioned Vault**         | A vault where only allowlisted addresses can deposit, in either tranche. Access controlled by the Pool Manager.                                                                               |
| **Permissionless Vault**       | A vault where any address can deposit — a future capability; today's vaults are permissioned.                                                                                                 |
| **Pool Manager**               | A professional underwriter who evaluates borrowers, structures loans, stakes collateral that anchors the junior tranche, and manages vaults.                                                  |
| **Principal**                  | The total loan amount requested by the borrower and funded by investors across both tranches.                                                                                                 |
| **Protocol Fee**               | A 0.5% fee sent to the treasury, taken from investor deposits in either tranche.                                                                                                              |
| **Recovery Pool**              | On default, the vault's full balance (slashed collateral, seized pledge proceeds) allocated to tranches in seniority order via `distribute_recovery`.                                         |
| **Related Party**              | A manager-declared disclosure flag for a deal that off-chain policy considers related, even where the borrower and manager addresses don't literally match.                                   |
| **Renegotiation**              | Process where the Pool Manager proposes new loan terms (rate + term); approving now requires both the manager and the borrower to authorize it. Active only.                                  |
| **Reserve Fee**                | The protocol's share of each period's interest, taken as the most senior bucket in the payment waterfall (default 10%).                                                                       |
| **Security Admin**             | Protocol role with emergency pause/unpause powers.                                                                                                                                            |
| **Senior Tranche**             | The protected investor layer, paid first each period and only loses once junior is wiped out. Opens only after the junior tranche is locked.                                                  |
| **SEP-41**                     | Stellar Ecosystem Proposal 41 — the fungible token standard on Stellar/Soroban.                                                                                                               |
| **SEP-45**                     | Stellar's web authentication standard for smart (contract) accounts — used for Trilobyte's passkey sign-in.                                                                                   |
