Term	Definition
Agentic Payment	A payment or transaction flow initiated by an AI agent or automated system, often using budget limits, permissions, subaccounts, or agent-native standards.
API/SDK	Developer interfaces that allow partners to integrate City Protocol modules such as tokenized products, vaults, swaps, ramps, KYC/AML, payments, and lending.
Attestation	A verifiable statement about a product or vault, such as proof of reserves, collateralization level, NAV report hash, service-provider confirmation, or settlement record.
Chain Abstraction	An infrastructure that lets users or applications interact across chains without manually managing bridges, gas tokens, or chain-specific routing.
City Protocol	Open infrastructure for neofinance, built around TaaS, VaaS, and NaaS.
Collateralization Level	The ratio between pledged collateral and outstanding obligations. It is commonly used in lending or RWA-backed products to monitor protection of principal.
Creator-Bound Execution	A VaaS design principle where the vault creator or curator defines the product mandate, and strategy managers execute only within approved boundaries.
Curator	A participant that defines or manages a vault's strategy mandate, risk limits, accepted assets, fees, redemption policy, and approved venues.
DeFi Yield Vault	A vault that allocates capital to approved DeFi strategies such as lending markets, liquidity venues, structured positions, or market-neutral strategies.
Deviation Check	An oracle or NAV control that flags or pauses updates when a reported value moves beyond a predefined threshold.
Emergency Pause	A governance or security control that can halt deposits, withdrawals, allocation, redemption, or other vault actions during abnormal conditions.
Epoch-Based Redemption	A redemption process where withdrawal requests accumulate during a window, pricing is locked at epoch close, required liquidity is calculated, settlement assets are verified, and users claim after fulfillment.
General-Purpose Attestation Engine	The TaaS module that connects product claims to verifiable records across reserves, collateral, NAV reports, deployment, service providers, and settlement.
Investor Management	The TaaS module for eligibility, KYC/AML, jurisdictional rules, accreditation checks, allowlists, denylists, subscription limits, and transfer restrictions.
KYC/AML	Know Your Customer and Anti-Money Laundering controls used to verify users, screen risk, and meet product or jurisdictional requirements.
LP	Liquidity provider or vault participant who deposits assets into a vault and receives shares, receipts, or claims according to the product design.
Managed Account	A strategy structure where capital may be managed in a dedicated account rather than a fully public tokenized share product.
Market-Neutral Strategy	A strategy designed to reduce broad market direction exposure while seeking returns from funding spreads, pricing inefficiencies, statistical signals, or relative value.
Multichain Distribution	The process of making a tokenized product available across supported networks and applications while preserving metadata, access rules, oracle data, reporting, and redemption logic.
NaaS	Neofinance as a Service. City Protocol's API/SDK layer for integrating modules such as vaults, yield, swaps, ramps, KYC/AML, payments, cards, lending, rewards, and agentic payment flows.
NAV	Net Asset Value. A measure of product or vault value after accounting for assets, liabilities, accrued fees, and other adjustments.
NAV Monitoring Oracle	The infrastructure that collects inputs, validates data, checks deviations, requires signers where needed, and publishes NAV or share price data.
Neofinance	The convergence of traditional financial products, onchain infrastructure, and consumer-grade fintech experience.
On/Off-Ramp	Infrastructure that allows users to move between fiat currency and crypto assets.
Oracle Quorum	A requirement that multiple authorized signers or data sources approve a NAV or oracle update before it becomes authoritative.
Permission Change Log	A record of changes to roles, access rules, strategy approvals, signers, or other sensitive vault parameters.
Policy Controller	A VaaS component that stores configurable parameters such as accepted assets, deposit caps, fees, redemption windows, risk thresholds, and eligibility rules.
Proof of Deployment	Evidence that vault assets have been allocated to approved strategies, accounts, or venues according to the vault mandate.
Proof of Reserves	Verification that assets backing a product or vault exist and correspond to reported obligations or claims.
Redemption Manager	The VaaS module that handles withdrawal requests, epoch closure, price locks, liquidity calculation, fulfillment status, and claim execution.
RWA	Real-World Asset. A traditional, offchain, or tangible asset or claim that is represented or financed onchain, such as private credit, receivables, treasuries, commodities, or secured lending exposure.
Security Governance Layer	VaaS controls such as multisig governance, execution timelocks, NAV signer quorum, strategy whitelisting, role-based permissions, and emergency pauses.
Settlement Record	A verifiable record that shows redemption, withdrawal, or other settlement activity has been processed.
SPaaS	Structured Product as a Service. City Protocol's product-construction layer for composing tokenized assets, verified vaults, and approved components into rules-based onchain structured products.
Strategy Debt	A vault accounting concept that tracks how much capital has been allocated to a strategy or venue and remains owed back to the base vault.
Strategy Manager	A participant responsible for allocating capital within approved strategies, venues, assets, and risk limits.
Strategy Whitelisting	The process of restricting capital deployment to approved strategies, venues, borrowers, or accounts.
Structured Product	A product wrapper with defined components, methodology, NAV, fees, eligibility rules, and lifecycle terms. It can represent a multi-vault allocation, thematic basket, manager strategy, model portfolio, or other structured exposure.
Subaccount	A separate account used for controlled spending, agent activity, budgeting, or delegated transaction permissions.
Subgraph-Level Indexing	Indexing of vault events such as deposits, withdrawals, subscriptions, redemptions, NAV reports, fees, settlement records, strategy debt, and permission changes.
TaaS	Tokenization as a Service. City Protocol's infrastructure for transforming yield sources into programmable, verifiable, distribution-ready onchain products.
Tokenized Yield Product	An onchain product that represents exposure to a yield source, vault, strategy, fund, credit asset, or other return-generating product.
