## City Protocol

- [Welcome to City Protocol](https://city-protocol.gitbook.io/docs/welcome-to-city-protocol.md): An infrastructure to democratize structured products onchain that align with different risk profiles and investment goals.
- [Introduction](https://city-protocol.gitbook.io/docs/platform/introduction.md): What City Protocol is, what it offers and where it stands as of September 2026.
- [The problem](https://city-protocol.gitbook.io/docs/platform/introduction/the-problem.md): Why packaged investing stays gated, and why every onchain issuer rebuilds the same stack.
- [Existing onchain infrastructure](https://city-protocol.gitbook.io/docs/platform/introduction/existing-onchain-infrastructure.md): The assets, settlement, standards and regulation that onchain structured products build on.
- [How City Protocol differs](https://city-protocol.gitbook.io/docs/platform/introduction/how-city-protocol-differs.md): Shared manufacturing for structured products, with two architectures under one layer.
- [Glossary](https://city-protocol.gitbook.io/docs/platform/introduction/glossary.md): Definitions of the terms used across the City Protocol documentation, from the products and their contracts to tokenization, verification and Polis Points.
- [Products](https://city-protocol.gitbook.io/docs/platform/products.md): Curated Vaults and Onchain Token Portfolios, offered to users through Venzo.
- [Curated Vaults](https://city-protocol.gitbook.io/docs/platform/products/curated-vaults.md): Access to institutional yield strategies, run by a named curator inside a mandate that the contracts enforce.
- [Onchain Token Portfolios](https://city-protocol.gitbook.io/docs/platform/products/onchain-token-portfolios.md): A rules-based basket of tokenized equities, bought into the participant's own account in one click.

- [Deposits, capital flow and redemption](https://city-protocol.gitbook.io/docs/platform/product-mechanics/how-curated-vaults-work/deposits-capital-flow-and-redemption.md): How capital enters a Curated Vault through the policy gate, settles through asynchronous requests and leaves through liquid or epoch-based redemption.
- [NAV, oracle and proof of deployment](https://city-protocol.gitbook.io/docs/platform/product-mechanics/how-curated-vaults-work/nav-oracle-and-proof-of-deployment.md): How a Curated Vault strikes its NAV, which checks a NAV report clears before settlement uses it, and how vault state and deployed capital are verified.
- [Mandate, execution and parameters](https://city-protocol.gitbook.io/docs/platform/product-mechanics/how-curated-vaults-work/mandate-execution-and-parameters.md): How the curator's mandate bounds strategy execution, how the contracts and venue controls enforce it, and what each vault configures before launch.

- [OTP security and risk controls](https://city-protocol.gitbook.io/docs/platform/product-mechanics/how-otps-work/otp-security-and-risk-controls.md): Every OTP control and where it acts, what an emergency pause halts, and the principal OTP risks with the controls that address them.
- [Technical overview](https://city-protocol.gitbook.io/docs/platform/product-mechanics/how-otps-work/technical-overview.md): How the OTP infrastructure is built: its eight components, how they connect, the portfolios it runs as of September 2026 and what arrives with the next phase.
- [Smart account specification](https://city-protocol.gitbook.io/docs/platform/product-mechanics/how-otps-work/technical-overview/smart-account-specification.md): The OTP smart account: its implementation, how its address is derived, the rules that never change, deployment, recovery, off-chain records and value.
- [Permission specification](https://city-protocol.gitbook.io/docs/platform/product-mechanics/how-otps-work/technical-overview/permission-specification.md): The two permissions through which the automation signer acts: the Approval and Trade scopes, their rules and limits, what they deny, and how a grant lives and renews.
- [Trade execution specification](https://city-protocol.gitbook.io/docs/platform/product-mechanics/how-otps-work/technical-overview/trade-execution-specification.md): How a Buy, Sell or Rebalance request becomes an onchain trade: requests and their states, the reads, each action's plan, price checks, batch submission, deposits and withdrawals.
- [Security model and trust assumptions](https://city-protocol.gitbook.io/docs/platform/product-mechanics/how-otps-work/technical-overview/security-model-and-trust-assumptions.md): What the OTP design guarantees, which layer enforces each guarantee, the trust boundary on price, what a holder still trusts, and how the design fails safe.
- [Deployments and verification](https://city-protocol.gitbook.io/docs/platform/product-mechanics/how-otps-work/technical-overview/deployments-and-verification.md): What the OTPs run on as of September 2026: the shared account infrastructure, each chain's settlement token, venue and reference prices, the reviewed registry, and how to verify an account onchain.
- [Issuance & Operation Layer](https://city-protocol.gitbook.io/docs/platform/product-mechanics/issuance-and-operation-layer.md): The product layer that launches and runs Curated Vault products and OTPs through one seven-stage lifecycle.
