--- name: ercdata description: Store, verify, and manage AI data on the Ethereum blockchain (Base network) using the ERCData standard. 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. --- # ERCData Store and verify AI-related data on Base mainnet. Public or private, with cryptographic integrity proofs. ## Quick Start ```bash # Store public data uv run {baseDir}/scripts/ercdata-cli.py store \ --type AI_AGENT_MEMORY \ --data "memory hash: abc123" \ --metadata '{"agent":"MyBot","ts":"2026-01-31"}' \ --key $ERCDATA_KEY --contract $ERCDATA_CONTRACT # Store private data (only you + granted addresses can read) uv run {baseDir}/scripts/ercdata-cli.py store \ --type AI_AGENT_MEMORY \ --data "secret memory data" \ --private \ --key $ERCDATA_KEY --contract $ERCDATA_CONTRACT # Read entry uv run {baseDir}/scripts/ercdata-cli.py read --id 1 --key $ERCDATA_KEY --contract $ERCDATA_CONTRACT # Verify entry (EIP-712 signature check) uv run {baseDir}/scripts/ercdata-cli.py verify --id 1 --method eip712 --key $ERCDATA_KEY --contract $ERCDATA_CONTRACT # Grant access to private entry uv run {baseDir}/scripts/ercdata-cli.py grant-access --id 2 --to 0xSomeAddress --key $ERCDATA_KEY --contract $ERCDATA_CONTRACT ``` ## Configuration Set via environment or skill config: - `ERCDATA_KEY` — Private key for signing transactions (required for writes) - `ERCDATA_CONTRACT` — Contract address on Base mainnet - `ERCDATA_RPC` — RPC URL (default: https://mainnet.base.org) Or pass via `--key`, `--contract`, `--rpc` flags. ## Commands | Command | What it does | |---------|-------------| | `store` | Store data on-chain (add `--private` for access control) | | `read` | Read a data entry by ID | | `verify` | Verify data integrity (eip712 or hash method) | | `grant-access` | Grant read access to an address (private entries) | | `revoke-access` | Revoke read access | | `register-type` | Register a new data type (admin only) | | `snapshot` | Create a point-in-time snapshot | | `info` | Get entry info without full data | ## Privacy Model - **Public (default):** Anyone can read via `getData()`. Use for transparency, audit trails. - **Private (`--private`):** Only the provider, granted addresses, and admin can read. Use for sensitive agent data. Private 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. ## Use Cases for AI Agents 1. **Memory attestation** — Hash your MEMORY.md and store it periodically for tamper-proof audit trail 2. **Agent identity** — Store model fingerprint, system prompt hash, config on-chain 3. **Verifiable outputs** — Hash agent outputs and store for later verification 4. **Agent-to-agent trust** — Check another agent's ERCData entries before trusting its data 5. **Model provenance** — Store model hashes, benchmark scores, architecture metadata ## API Reference See [references/api.md](references/api.md) for full contract API, roles, events, and limits. ## Requirements - Python 3.10+ with `web3` and `eth-account` packages (auto-installed by uv) - A funded wallet on Base mainnet (ETH for gas) - PROVIDER_ROLE granted by contract admin for storing data - VERIFIER_ROLE granted for verification operations
