Coal is a programmable commerce platform for hosted checkout, merchant APIs, payment links, paywalls, recurring billing, and agentic commerce flows.

Coal is built around a simple split:

Coal handles checkout orchestration, merchant operations, payer-info capture, recurring billing, and dual-protocol agent settlement flows on Base.
0G adds the sidecar layer for artifact storage, receipt proof anchoring, merchant memory, and AI commerce endpoints.

This repo is an active product branch, not a tiny demo. The current codebase includes:

hosted checkout and payment links (humans)
dual-protocol agent payments — Coinbase x402 (v1) and OKX APP (v2) on the same /verify endpoint
MCP server for Claude Desktop / Cursor / ChatGPT agents (multi-tenant, per-request credentials)
merchant dashboard and onboarding
payer-info collection at checkout
recurring billing foundations
widget/embed surfaces + coal-react SDK on npm
docs site + OpenAPI playground
demo store with verified-payment download flow
live agent demo running on 0G Compute (Qwen)
live 0G storage / chain / compute / KV / DA integration

0G Integration — 5 Components on Mainnet

Coal uses five 0G network components. All live on 0G mainnet. Full setup walkthrough lives on the docs site at usecoal.xyz/docs.

1. 0G Storage — Immutable Artifact Layer

Every payment receipt, merchant profile, and encrypted memory snapshot is published to 0G Storage as an immutable, content-addressed artifact. AI agents and apps can discover merchants and verify payments by reading these artifacts directly from the decentralized storage network.

Receipt payloads: tx hash, amount, payer address, merchant, metadata
Merchant profiles: name, products, paywalls, supported tokens, API endpoints
Encrypted memory: AES-256-GCM encrypted full catalog + settings (only Coal can decrypt)
Explorer: storagescan.0g.ai

2. 0G Chain — Receipt Proof Anchoring

After publishing a receipt to 0G Storage, Coal anchors a SHA-256 hash of the receipt payload on-chain via the CoalReceiptAnchor V2 smart contract. Creates a tamper-proof, independently verifiable proof that a specific payment happened at a specific time. V2 calls the DASigners precompile (epochNumber()) and embeds the current DA epoch into every anchor event.

Contract: 0x24a80A3Bb16d26D4063Ecd4B2fD64C6856E25E8b
Chain: 0G mainnet (chain ID 16661)
