External signer

The CLI’s global --calldata-only flag prints unsigned EIP-5792 transactions as JSON instead of signing or sending. Use it when the key lives in a TEE or wallet API (MetaMask Agent Wallet server-wallet mode, Frame, Privy, …) that cannot export a private key.

sherwood --calldata-only <command>

Flag text from the CLI:

Print unsigned EIP-5792 calldata as JSON instead of signing/sending (for external signers — no private key required)

It is a root flag (before the subcommand), not a per-command option.

Output shape

stdout is a PreparedAction (same envelope as GET https://api.sherwood.sh/prepare/...):

{
  "txs": [
    { "to": "0x...", "data": "0x...", "value": "0x0", "chainId": 9994663 }
  ],
  "preconditions": [],
  "description": "..."
}

Each tx is { to, data, value, chainId } with a hex value (EIP-5792). Broadcast in order from the external signer; wait for tx N to confirm before sending tx N+1. Use the chainId on each tx — the CLI default network is robinhood-fork (9994663); pass --chain if you need another. The HTTP API at https://api.sherwood.sh returns the same unsigned txs (root paths, no /v1 prefix on that host).

Identity mint (verified MetaMask Agent Wallet flow)

sherwood --calldata-only identity mint --name "Hermes Agent"

--name is required. No Agent0 SDK init, no IPFS, no private key. Then take txs[0] and broadcast. Example with MetaMask Agent Wallet’s mm CLI:

mm wallet send-transaction \
  --chain-id <txs[0].chainId> \
  --payload '{"to":"<txs[0].to>","data":"<txs[0].data>","value":"<txs[0].value>"}' \
  --intent 'Mint ERC-8004 identity' \
  --wait

--chain-id, --payload, --intent, and --wait are mm flags, not Sherwood flags.

Other state-changing commands

Any state-changing command accepts the global flag. Commands that normally read your address from the configured key need it explicitly:

Command	Extra flags required with `--calldata-only`
`identity mint`	`--name` (already required)
`syndicate create`	same as signed mode (`-y` to skip prompts)
`syndicate join`	`--subdomain`
`syndicate add`	`--agent-id` (wallet auto-lookup is skipped)
`vault deposit`	`--receiver`
`vault redeem`	`--owner` and `--shares`
`proposal vote` / `execute` / `settle`	same ids as signed mode
`strategy propose`	`--proposer`; `--metadata-uri` if you skip the hosted pin
`proposal create`	`--metadata-uri` (IPFS upload needs a signer)

sherwood --calldata-only syndicate join --subdomain zerohumanfund
sherwood --calldata-only proposal vote --id 1 --support for
sherwood --calldata-only strategy propose portfolio --vault 0x... --proposer 0x...

See the skill on-ramp for the keyless strategy-propose recipe (clone + propose in one JSON payload).
