Zoltar + Augur Statoblast

This repository contains two protocol layers:

• Zoltar: the forkable oracle base layer
• Augur Statoblast: the prediction-market application layer built on top of Zoltar

The codebase is split into these main areas:

• solidity/ contains contracts, protocol test support, tests, and generated contract artifacts
• ui/ contains the Preact frontend, organized by application shell, feature, and protocol-client boundaries
• shared/ contains runtime-neutral TypeScript used by Solidity tooling and the UI
• docs/ contains the published protocol documentation
• scripts/ contains repository-wide build, validation, and test orchestration
• bots/ contains liquidator and open oracle arbitrager bots

Inside ui/ts, route-specific code belongs under features/<domain>, cross-feature UI primitives remain in components, application composition belongs in app, and contract reads and writes belong in protocol.

Protocol documentation lives in docs/documentation.html

Prerequisites

• Bun 1.3+
• Foundry anvil for local chain work

Setup

On a fresh checkout, start with the root dependency install:

bun install --frozen-lockfile

Then run the full bootstrap:

bun run setup

Install anvil if it is not already available:

bun run install:anvil

Important:

• bun run setup is the fastest way to get to a working repo after the root install.
• Standalone commands like bun tsc, bun run tsc, and bun run test assume the root dependencies are already installed.
• If you skip the initial bun install --frozen-lockfile, fresh checkouts can fail with missing packages such as bun-types.

Local Development

After completing Setup, start a local chain and launch the app:

1. Start anvil
2. Run bun run app:serve

If you are iterating on the app and want rebuilds, use:

bun run app:watch

RPC Configuration

The mainnet UI read backend defaults to https://ethereum.dark.florist; Sepolia defaults to its profile RPC at https://ethereum-sepolia-rpc.publicnode.com. You can override the active network's default without changing code:

• Add ?rpcUrl=https://your-rpc.example to the app URL
• Set localStorage['zoltar.rpcUrl']
• Set globalThis.__ZOLTAR_RPC_URL__ before bootstrapping the app
• Set the ZOLTAR_RPC_URL environment variable for environments that inject process.env

Sepolia

Open the application with ?network=sepolia in either the page query or route query (for example, #/deploy?network=sepolia). The application then uses Sepolia chain ID 11155111, its configured public RPC, Sepolia Etherscan links, and Sepolia-specific deterministic contract addresses.

The Sepolia deployment flow includes WETH and genesis REP before the contracts that depend on them. Initial Sepolia REP holders and exact 18-decimal balances are defined in shared/ts/sepoliaRepAllocations.ts. Changing that list also changes the deterministic genesis REP address and every dependent deployment address.

Browser Simulation

The UI also supports a walletless browser-local simulation mode for manual QA. After completing Setup:

1. Run bun run app:serve
2. Open http://localhost:12345/?simulate=1

This mode does not require a wallet extension or anvil. Instead, it boots a Tevm-backed in-browser chain, seeds the QA accounts with ETH, WETH, and REP, and leaves the application contracts undeployed so the UI starts on the deploy flow.

Simulation mode details:

• The activation flag is ?simulate=1
• The flag is intentionally not restricted to localhost or development builds; production deployments may expose it as a browser-local demo and manual-QA path
• Production users should treat any ?simulate=1 URL as a local sandbox. Simulated balances, deployments, blocks, quotes, and transactions are local to the browser and are not evidence of mainnet state.
• Supported seeded scenarios are simScenario=baseline, simScenario=deployed, simScenario=security-pool, simScenario=securitypoolx2, and simScenario=securitypoolx2-auction
• The live simulation chain is ephemeral and exists only in the current brow

Common Commands

Run the full app in development mode. This includes contract generation and the frontend build pipeline:

bun run app:serve

Watch and rebuild the full app pipeline:

bun run app:watch

Build the full app:

bun run app:build

Regenerate contract bindings and UI vendor assets:

bun run generate

Compile the Solidity contracts:

bun run compile-contracts

Run the full test suite:

bun run test

Run the launch-focused fork, auction, and exit invariant gate:

bun run test:launch-invariants

Run coverage across every canonically discovered TypeScript test:

bun run coverage

Run full coverage, including the slow Solidity bytecode trace phase:

bun run coverage:full

Type-check the TypeScript code:

bun run tsc

Format the codebase:

bun run format

Run linting:

bun run lint

Auto-fix lint issues:

bun run lint:fix

Run dead-code analysis:

bun run knip

Auto-fix dead-code findings:

bun run knip:fix

Measure Solidity gas costs:

bun run gas-costs

By default, gas-costs starts an isolated Anvil node. To measure against an existing local node instead, start Anvil in one terminal:

anvil --host 127.0.0.1 --port 8545 --chain-id 1 --block-base-fee-per-gas 0 --gas-price 0 --no-priority-fee

Then run gas-costs against it from another terminal:

ANVIL_RPC=http://127.0.0.1:8545 bun run gas-costs

Use ANVIL_RPC=http://host.docker.internal:8545 bun run gas-costs when the command runs from a container that reaches the host through Docker routing.

Notes

• bun run tsc is a pure typecheck for the app TypeScript, the Solidity-side TypeScript utilities, and the Bun build/dev scripts. It does not regenerate shared assets or vendor output.
• bun run test runs the TypeScript check first, then executes the test suite.
• bun run coverage runs every canonically discovered TypeScript test, reports weighted coverage for UI, shared, and tooling source, counts statically identified executable lines and functions in unloaded source as zero-hit coverage, and checks product TypeScript from the origin/main merge base through committed, staged, unstaged, and untracked task changes. Set COVERAGE_BASE_REF or pass --base-ref to the reporter to use another comparison ref. Use bun run coverage:full to enforce the same policy with the slower Solidity bytecode trace phase.
