Skills ercdata

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

# 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

Memory attestation — Hash your MEMORY.md and store it periodically for tamper-proof audit trail
Agent identity — Store model fingerprint, system prompt hash, config on-chain
Verifiable outputs — Hash agent outputs and store for later verification
Agent-to-agent trust — Check another agent's ERCData entries before trusting its data
Model provenance — Store model hashes, benchmark scores, architecture metadata

API Reference

See 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
