| peaqID         | W3C DID anchoring the machine's on-chain identity. Portable across chains.                                                                                                                            |
| Identity NFT   | Minted automatically by IdentityRegistry at registration. `tokenId == machineId`.                                                                                                                     |
| Machine NFT    | LayerZero V2 ONFT linking to the machine's financial profile. Minted via a separate `mintNft` call after registration. See [Machine NFT ownership](/peaqos/concepts/machine-nft#ownership-semantics). |
| 1 PEAQ bond    | Sent as `msg.value` on the `register()` call (the contract's current `minBond`). Required to graduate onto the MCR rated scale later.                                                                 |
| Machine wallet | Per-machine EVM keypair, generated by the SDK.                                                                                                                                                        |

## How activation works

The <Tooltip tip={G.sdk.def}>SDK</Tooltip> exposes each step as a discrete call so you can compose your own flow. For one-shot activation from the terminal, the CLI runs all six steps idempotently. Re-runs skip already-completed steps using `./peaqos.log` as the resume marker:

```bash theme={"theme":{"light":"github-light-default","dark":"github-dark"}}
# self-managed: caller's key drives every step
peaqos activate --doc-url "https://example.com/docs" --data-api "https://example.com/events"

# proxy-managed: --for and --machine-key must be used together
peaqos activate --for 0xMachineAddress --machine-key ./machine.key --doc-url "https://example.com/docs" --data-api "https://example.com/events"
```

See [CLI reference: activate](/peaqos/cli#peaqos-activate) for all flags (including `--skip-funding`, `--doc-url`, `--data-api`, `--visibility`).

<Steps>
  <Step title="Generate a keypair">
    The SDK generates a new keypair for the machine. This becomes the machine's <Tooltip tip={G.signer.def}>signing identity</Tooltip> on peaq chain.

    ```typescript theme={"theme":{"light":"github-light-default","dark":"github-dark"}}
    import "dotenv/config";
    import { PeaqosClient } from "@peaqos/peaq-os-sdk";

    const client = PeaqosClient.fromEnv();
    const keypair = PeaqosClient.generateKeypair();
    // { address: "0x...", privateKey: "0x..." }
    ```
  </Step>

  <Step title="Fund the wallet">
    Fund the machine's <Tooltip tip={G.wallet.def}>wallet</Tooltip> with <Tooltip tip={G.peaqToken.def}>PEAQ</Tooltip> for <Tooltip tip={G.gas.def}>gas</Tooltip> and the 1 PEAQ <Tooltip tip={G.bond.def}>bond</Tooltip>.

    Projects with partner access to the peaq <Tooltip tip={G.gasStation.def}>Gas Station</Tooltip> can request initial gas from the faucet using the SDK (2FA-gated). Otherwise, fund the wallet directly from any PEAQ-holding address.
  </Step>

  <Step title="Register the machine">
    Two patterns depending on your deployment model.

    <Tabs>
      <Tab title="Self-managed">
        <Tooltip tip={G.ownerOperator.def}>Owner equals operator</Tooltip>. One machine, one wallet. Use `registerMachine` to register the machine under its own keypair.

        ```typescript theme={"theme":{"light":"github-light-default","dark":"github-dark"}}
        const machineClient = new PeaqosClient({
          rpcUrl: client.rpcUrl,
          privateKey: keypair.privateKey,
          contracts: client.contracts,
        });
        const machineId = await machineClient.registerMachine();
        console.log(machineId);
        // Returns the on-chain machine ID (number)
        ```

        Full guide: [Self-managed onboarding](/peaqos/guides/self-managed-onboarding).
      </Tab>

      <Tab title="Proxy operator">
        One owner runs a fleet. Register machines on their behalf using `registerFor`. Each machine gets its own <Tooltip tip={G.did.def}>peaqID</Tooltip>; the <Tooltip tip={G.proxyOperator.def}>proxy operator</Tooltip> controls delegation and mints the Machine NFT in a follow-up step.

        ```typescript theme={"theme":{"light":"github-light-default","dark":"github-dark"}}
        const machineId = await client.registerFor(keypair.address);
        console.log(machineId);

        // Create Machine Client after registration to mint NFT and link DID
        const machineClient = new PeaqosClient({
          rpcUrl: client.rpcUrl,
          privateKey: keypair.privateKey,
          contracts: client.contracts,
        });
        ```

        Full guide: [Proxy operator fleet setup](/peaqos/guides/proxy-operator-fleet).
      </Tab>
    </Tabs>
  </Step>

  <Step title="Mint the Machine NFT and link the DID">
    <Tabs>
      <Tab title="Self-managed">
        NFT and the <Tooltip tip={G.didAttributes.def}>DID attributes</Tooltip> are written by the machine itself.

        ```typescript theme={"theme":{"light":"github-light-default","dark":"github-dark"}}
        const tx = await machineClient.mintNft(machineId, keypair.address);
        const nftTokenId = await machineClient.tokenIdOf(machineId);

        await machineClient.writeMachineDIDAttributes({
          machineId,
          nftTokenId,
          operatorDid: "",
          documentationUrl: "https://example.com/docs",
          dataApi: "https://example.com/events",
          dataVisibility: "public",
        });
        ```
      </Tab>

      <Tab title="Proxy operator">
        NFT is minted to the machine's address, and the DID attributes are written by the machine itself. Proxy pays bond fee, and machine pays DID fees.

        ```typescript theme={"theme":{"light":"github-light-default","dark":"github-dark"}}
        const tx = await client.mintNft(machineId, keypair.address);
        const nftTokenId = await client.tokenIdOf(machineId);

        await machineClient.writeMachineDIDAttributes({
          machineId,
          nftTokenId,
          operatorDid: "",
          documentationUrl: "https://example.com/docs",
          dataApi: "https://example.com/events",
          dataVisibility: "public",
        });
        ```

        Full guide: [Proxy operator fleet setup](/peaqos/guides/proxy-operator-fleet).
      </Tab>
    </Tabs>

    `mintNft` returns a new, independent `tokenId` on the MachineNFT contract. `writeMachineDIDAttributes` binds `machineId` and `nftTokenId` to the machine's DID. See [Machine NFT ownership](/peaqos/concepts/machine-nft#ownership-semantics) for the full rationale.
  </Step>

  <Step title="Confirm registration">
    After all three calls the machine has a peaqID, an <Tooltip tip={G.identityNft.def}>Identity NFT</Tooltip>, a <Tooltip tip={G.machineNft.def}>Machine NFT</Tooltip>, and a 1 PEAQ bond. Query the machine's profile against the [MCR API](/peaqos/api-reference/get-machine), where `{did}` is `did:peaq:<machine_address>`:

    ```bash theme={"theme":{"light":"github-light-default","dark":"github-dark"}}
    curl "${PEAQOS_MCR_API_URL}/machine/did:peaq:0xYourMachineAddress"
    ```

    The machine is `Provisioned` at first: on-chain, but not yet rated. It graduates onto the rated scale once **both** gates clear: a sustained first-to-last <Tooltip tip={G.event.def}>event</Tooltip> span, **and** either enough qualifying revenue events or enough activity events. The events condition is `OR`, so activity-only machines can graduate without revenue. See [Machine Credit Rating](/peaqos/concepts/machine-credit-rating#lifecycle-provisioned-graduation).
  </Step>
</Steps>

## After activation

Once a machine is registered, later functions add new capabilities.

<Info>
  **Multichain:** peaqID, Machine NFT, and the <Tooltip tip={G.machineMarkets.def}>Service Registry</Tooltip> stay canonical on peaq. <Tooltip tip={G.smartAccount.def}>Smart accounts</Tooltip> and Machine NFTs deploy to supported chains (<Tooltip tip={G.base.def}>Base</Tooltip> first) via DIDLite and IdentityLite mirrors. See the [Omni-chain concept](/peaqos/concepts/omni-chain) and the [roadmap](/roadmap).
