Use when an agent needs to store data fingerprints on-chain, verify data integrity, create audit trails, manage access control for private data, or interact with the ERCData smart contract. Supports public and private storage, EIP-712 verification, snapshots, and batch operations.\n---\n\n# ERCData\n\nStore and verify AI-related data on Base mainnet. Public or private, with cryptographic integrity proofs.\n\n## Quick Start\n\n```bash\n# Store public data\nuv run {baseDir}/scripts/ercdata-cli.py store \\\n  --type AI_AGENT_MEMORY \\\n  --data \"memory hash: abc123\" \\\n  --metadata '{\"agent\":\"MyBot\",\"ts\":\"2026-01-31\"}' \\\n  --key $ERCDATA_KEY --contract $ERCDATA_CONTRACT\n\n# Store private data (only you + granted addresses can read)\nuv run {baseDir}/scripts/ercdata-cli.py store \\\n  --type AI_AGENT_MEMORY \\\n  --data \"secret memory data\" \\\n  --private \\\n  --key $ERCDATA_KEY --contract $ERCDATA_CONTRACT\n\n# Read entry\nuv run {baseDir}/scripts/ercdata-cli.py read --id 1 --key $ERCDATA_KEY --contract $ERCDATA_CONTRACT\n\n# Verify entry (EIP-712 signature check)\nuv run {baseDir}/scripts/ercdata-cli.py verify --id 1 --method eip712 --key $ERCDATA_KEY --contract $ERCDATA_CONTRACT\n\n# Grant access to private entry\nuv run {baseDir}/scripts/ercdata-cli.py grant-access --id 2 --to 0xSomeAddress --key $ERCDATA_KEY --contract $ERCDATA_CONTRACT\n```\n\n## Configuration\n\nSet via environment or skill config:\n- `ERCDATA_KEY` — Private key for signing transactions (required for writes)\n- `ERCDATA_CONTRACT` — Contract address on Base mainnet\n- `ERCDATA_RPC` — RPC URL (default: https://mainnet.base.org)\n\nOr pass via `--key`, `--contract`, `--rpc` flags.\n\n## Commands\n\n| Command | What it does |\n|---------|-------------|\n| `store` | Store data on-chain (add `--private` for access control) |\n| `read` | Read a data entry by ID |\n| `verify` | Verify data integrity (eip712 or hash method) |\n| `grant-access` | Grant read access to an address (private entries) |\n| `revoke-access` | Revoke read access |\n| `register-type` | Register a new data type (admin only) |\n| `snapshot` | Create a point-in-time snapshot |\n| `info` | Get entry info without full data |\n\n## Privacy Model\n\n- **Public (default):** Anyone can read via `getData()`. Use for transparency, audit trails.\n- **Private (`--private`):** Only the provider, granted addresses, and admin can read. Use for sensitive agent data.\n\nPrivate entries store the same data on-chain but gate `getData()` access. Note: raw transaction calldata is still visible on-chain explorers. For maximum privacy, encrypt data before storing.\n\n## Use Cases for AI Agents\n\n1. **Memory attestation** — Hash your MEMORY.md and store it periodically for tamper-proof audit trail\n2. **Agent identity** — Store model fingerprint, system prompt hash, config on-chain\n3. **Verifiable outputs** — Hash agent outputs and store for later verification\n4. **Agent-to-agent trust** — Check another agent's ERCData entries before trusting its data\n5. **Model provenance** — Store model hashes, benchmark scores, architecture metadata\n\n## API Reference\n\nSee [references/api.md](references/api.md) for full contract API, roles, events, and limits.\n\n## Requirements\n\n- Python 3.10+ with `web3` and `eth-account` packages (auto-installed by uv)\n- A funded wallet on Base mainnet (ETH for gas)\n- PROVIDER_ROLE granted by contract admin for storing data\n- VERIFIER_ROLE granted for verification operations\n","readmeExcerpt":"--- name: ercdata description: Store, verify, and manage AI data on the Ethereum blockchain (Base network) using the ERCData standard.
