ERC-8004 Skill

Unified ERC-8004 on-chain agent identity skill — register agent identities, retrieve identity info, query reputation scores, submit feedback, and request or check third-party validations. Read operations work without a wallet. Write operations require an unlocked wallet.

Usage

bun run erc8004/erc8004.ts <subcommand> [options]

Subcommands

register

Register a new agent identity on-chain using the ERC-8004 identity registry. Returns a transaction ID. Check the transaction result to get the assigned agent ID. Requires an unlocked wallet.

Options:

```
--uri
```
(optional) — URI pointing to agent metadata (IPFS, HTTP, etc.)
```
--metadata
```
(optional) — JSON array of

{"key": "...", "value": "<hex>"}
```
pairs (values are hex-encoded buffers)
```
--fee
```
(optional) — Fee preset (
```
low
```
,
```
medium
```
,
```
high
```
) or micro-STX amount

}

validation-status

bun run erc8004/erc8004.ts validation-status <request-id>

Arguments:

```

Notes

Read operations (

get-identity

get-reputation

validation-status

) work without a wallet

Write operations (

register

give-feedback

request-validation

) require an unlocked wallet (

bun run wallet/wallet.ts unlock

)

Agent IDs are assigned by the contract upon registration — check the transaction result to find your assigned ID
Feedback values are signed integers; positive values improve reputation, negative values lower it
Validation responses are scores between 0 and 100 submitted by the designated validator
