origin-dollar: Instructions file for Claude Code

CLAUDE.md

origin-dollar CLAUDE.md is an instructions file for Claude Code from OriginProtocol/origin-dollar. It costs 5,053 tokens per session, scanned A, original, MIT.

A repository instruction file for Origin Dollar, a project containing smart contracts for blockchain-based tokens. It documents the project layout, development tools, setup commands, and optional private dependencies.

In plain words
What is it for?
Use it when working on the Origin Dollar smart-contract monorepo, a repository that contains several related projects. It covers Foundry, Hardhat, environment setup, deployments, and contract locations.
Why use it?
It gives a coding agent the project-specific rules and commands it needs to work in this repository. This avoids guessing how the contracts are built, tested, or deployed.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Claude Code.

This is OriginProtocol/origin-dollar's own configuration. It tells Claude Code how to work on origin-dollar itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything origin-dollar configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is const log = require("../utils/logger")("module-name");.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

origin-dollar CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

Origin DeFi's OTokens monorepo containing smart contracts for:

  • OUSD (Origin Dollar) - a yield-bearing stablecoin
  • OETH (Origin Ether) - an Ethereum liquid staking token

Deployed on Ethereum Mainnet, Base, Arbitrum, Plume, Hoodi, and HyperEVM. Origin Sonic (OS) is being wound down on Sonic; its contracts and automation were removed from the repo (see git history). All smart contract work happens in the contracts/ directory.

Toolchain

Foundry is the contract toolchain: forge (driven by the Makefile) builds the contracts, runs the contract test suite, and executes deployments. pnpm ops runs operational commands and Anvil provides local forks. The committed deployments/ descriptors are the shared address/ABI registry.

Setup

cd contracts
cp dev.env .env          # Set MAINNET_PROVIDER_URL to an Alchemy/Infura endpoint
make install             # foundryup (v1.8.3), forge soldeer install, install-deps.sh, pnpm i

Key .env variables: MAINNET_PROVIDER_URL (required), BASE_PROVIDER_URL, ARBITRUM_PROVIDER_URL, HYPEREVM_PROVIDER_URL, BEACON_PROVIDER_URL (beacon-proof fork tests), and optional FORK_BLOCK_NUMBER_<CHAIN> pins for Foundry fork tests (unset = latest block; refresh with make update-fork-blocks). The ops CLI and anvil.sh also resolve Ethereum from MAINNET_PROVIDER_URL (legacy fallback: PROVIDER_URL).

Real deployments additionally need DEPLOYER_ADDRESS and the encrypted deployerKey keystore (cast wallet import deployerKey --interactive).

@oplabs/talos-client (private, optional)

pnpm i deliberately does not install @oplabs/talos-client. It is declared as an optional peer dependency so that CI and external contributors can install this repo without GitHub Packages credentials.

Nothing local needs it. pnpm ops, tsx tasks/run.ts <action> and the tests all load and run without it. Only the runner image does: runner.ts (container entrypoint) imports it statically, and tasks/lib/signer.ts require()s it lazily for the Postgres nonce queue, which is gated on DATABASE_URL — unset locally, so the require never fires. dockerfile-actions installs it with the talos_package_token build secret, reading the pinned version from peerDependencies.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
