# Send ERCData to your agent
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
## Fast path
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
```

## Documentation

### 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

CommandWhat it doesstoreStore data on-chain (add --private for access control)readRead a data entry by IDverifyVerify data integrity (eip712 or hash method)grant-accessGrant read access to an address (private entries)revoke-accessRevoke read accessregister-typeRegister a new data type (admin only)snapshotCreate a point-in-time snapshotinfoGet 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
