# ZERO DELTA

- [Why ZeroDelta?](https://docs.glacislabs.com/zero-delta/why-zerodelta.md): The clearing house for RWAs. ZeroDelta matches institutional RWA orderflow, delivering compliant, zero-slippage execution for capital moving at scale.
- [Architecture](https://docs.glacislabs.com/zero-delta/architecture.md)
- [Integration Guide](https://docs.glacislabs.com/zero-delta/integration-guide.md): Integrate the clearing house. One quote, one contract call.
- [Discover What You Can Trade](https://docs.glacislabs.com/zero-delta/integration-guide/discover-what-you-can-trade.md): The tradeable surface is a cross product narrowed by live measurement, not a list of routes. Four calls, one copy-paste function, and the three filtering mistakes to design out.
- [API](https://docs.glacislabs.com/zero-delta/integration-guide/api.md): Complete reference for the ZeroDelta read API: quoting, transaction tracking, and chain/token/route/solver/protocol discovery. For an integration walkthrough see the Integration Guide.
- [Models](https://docs.glacislabs.com/zero-delta/integration-guide/api/models.md): Schema reference for the ZeroDelta read API: envelope, error codes, status vocabulary, compliance decision, quote and order shapes, and the tracked transaction with its chained-journey fields.
- [Transaction Models](https://docs.glacislabs.com/zero-delta/integration-guide/api/transaction-models.md): The tracked transaction and its steps, including the chained-journey fields that describe a two-leg order as one user intent.
- [Smart Contracts](https://docs.glacislabs.com/zero-delta/integration-guide/smart-contracts.md): Contract interface, data types, events, error codes, deployments, and coverage. For the REST API, see the API Reference. Compiler: Solidity 0.8.19 (optimizer enabled, 200 runs). License: BUSL-1.1
- [Widget](https://docs.glacislabs.com/zero-delta/widget.md): Prebuilt UI for cross-chain stablecoin and real-world-asset settlement. Drop it in; the user's wallet always signs.
- [Install & Embed](https://docs.glacislabs.com/zero-delta/widget/install.md): Four ways onto the page — React, mount(), a script tag, or Next.js — plus the compatibility floor.
- [Configure](https://docs.glacislabs.com/zero-delta/widget/configure.md): Every prop the widget accepts — shared config, per-component props, events, wallets, coverage and compliance.
- [Theming](https://docs.glacislabs.com/zero-delta/widget/theming.md): Twenty-three tokens, twenty-two CSS variables, and the isolation rule that makes them the only way in.
- [The Keyless Proxy](https://docs.glacislabs.com/zero-delta/widget/keyless-proxy.md): The same-origin proxy you deploy so the browser never holds a ZeroDelta key — contract, reference handler and CSP.
- [API Reference](https://docs.glacislabs.com/zero-delta/widget/api-reference.md): The complete export surface, the headless engine, and what the widget deliberately does not do.
- [Points Program](https://docs.glacislabs.com/zero-delta/points-program.md): Hold supported tokens in your own wallet and earn ZeroDelta Points. How it works, how points are calculated, and the rules.
