Tangle CLI
Create, run, and operate blueprints on Tangle EVM.
Overview
The CLI bundles every workflow needed for the EVM-only SDK:
cargo tangle blueprint createscaffolds a new blueprint from the templates.cargo tangle blueprint run --protocol tangleboots a manager connected to the Tangle v2 contracts.cargo tangle blueprint register-tangleregisters an operator againstITangle,MultiAssetDelegation, andOperatorStatusRegistry.cargo tangle key *manages local and remote k256 keys viablueprint-keystore.
Installation
Linux, macOS, and Windows (WSL2) are supported.
Feature flags
Source installs enable full by default, including blueprint development,
registration, operator and key commands. Release archives and the shell
installer also enable remote-providers, which adds cargo tangle cloud;
add it to a source install with --features remote-providers. vm-debug
adds the Linux VM sandbox.
The release also includes cargo-tangle-cloud-<target>.tar.xz and its
.sha256 file for native Linux x86_64 and aarch64. These archives contain
cargo-tangle built from the same source with --no-default-features --features cloud-only. They expose only the cloud commands, with the same providers as the
standard archives, and have no Anvil, testcontainers or cargo-generate in the
production dependency graph. Chain and key libraries still link, because the
provider and pricing crates depend on them. Standard archives carry the full CLI
with cloud commands. Install the cloud-only flavor from source:
Verify the downloaded .sha256 file before extracting the archive.
Creating a New Blueprint
The scaffold asks for a source template, optional variables, and whether to skip prompts. The generated workspace already depends on blueprint-sdk with the tangle feature.
For Tangle blueprints, the scaffold also includes a
metadata/blueprint-metadata.json file. Publish that JSON to IPFS or HTTPS,
then set the resulting URI as metadata_uri in your deploy definition. Add
either metadata_hash or metadata_file as well so the deploy manifest pins
the expected payload digest onchain. The URI is what lands onchain; the full
JSON stays offchain and is what
tangle-cloud ingests to render tier-2 hosted blueprint surfaces.
For production tier-2 hosting, publish to ipfs:// and include an owner-signed
metadata attestation. If the shared host cannot verify provenance, it falls
back to the protocol-controlled generic blueprint UI.
Running a Blueprint on Tangle
The runner expects RPC URLs, a keystore, and the EVM contract coordinates. You can provide them via CLI flags or a settings.env file that the command loads before boot.
BLUEPRINT_ID=0 \
SERVICE_ID=0 \
TANGLE_CONTRACT=0x0165878A594ca255338adfa4d48449f69242Eb8F \

| Variable | Description |
|---|---|
BLUEPRINT_ID |
Blueprint registered on ITangle. |
SERVICE_ID |
Optional fixed service (leave unset to process all). |
TANGLE_CONTRACT |
ITangle contract address. |
STAKING_CONTRACT |
MultiAssetDelegation staking contract. |
STATUS_REGISTRY_CONTRACT |
OperatorStatusRegistry heartbeat contract. |
The CLI automatically ensures an ECDSA key exists under --keystore-path and derives the operator address from it.
Registering an Operator
register-tangle performs the on-chain registration + announcement flow in one command:
You can optionally set --rpc-endpoint to push metadata to a remote operator directory service during registration.
Service Lifecycle Commands
The cargo tangle blueprint service namespace mirrors everything exposed in Tangle.sol:
service requestsubmits a pending service with per-operator exposures, rich config payloads, and optional asset security requirements.service approve/service rejectlets operators respond to a request; approvals can include explicit asset commitments when the request included requirements.service join/service leavelet operators participate in dynamic membership services; leaving succeeds when the service's exit queue allows the legacy helper.service listandservice requestssurface active services vs. pending requests, with a--jsontoggle for scripting.
Requesting a Service
- Provide one
--operator-exposure-bpsper operator (basis points, 10_000 = 100%). Leave unset to fall back to the default BPS of 100% per operator. - Security requirements use the format
KIND:TOKEN:MIN:MAXwhereKINDisnativeorerc20. Use_/0for the native token placeholder. - TTLs are expressed in seconds to match the
Tangle.solschema.
Approving or Rejecting
# Simple staking approval
# Approval that matches request-level security requirements
--security-commitmentmirrors theKIND:TOKEN:EXPOSUREstructure expected byapproveServiceWithCommitments.- Use
service reject --request-id <ID>to decline participation.
Listing Services/Requests
Both commands read via TangleClient::{list_services,list_service_requests} and print either friendly tables or JSON for automation.
Blueprint Upgrade Flow
Shipping a new build of a blueprint touches three actors. The CLI gives each of them a first-class subcommand surface so nobody has to hand-craft calldata.
┌─────────────────────┐
│ blueprint owner │ publish-version → set-active-version
└─────────┬───────────┘
│
▼
┌─────────────────────┐
│ auditor / scanner │ attest submit → (optional) attest revoke
└─────────┬───────────┘
│
▼
┌─────────────────────┐
│ service operator │ service set-policy → service ack-version
└─────────────────────┘
1. Publish a new version (blueprint owner)
# Hash the artifact locally, pin to IPFS, and submit publishBinaryVersion.
--binary <path>is hashed (sha256) locally; the digest becomessha256Hashon-chain.- Provide either
--binary-uri ipfs://<cid>(you've already pinned) or--pin-to-ipfs(the CLI pins viaIPFS_API_URL+IPFS_API_TOKENif set, orPINATA_JWTas a fallback). --attestation-bundle <path>is hashed and stored asattestationHash. Pass--attestation-hash <hex>to override directly (e.g. when the bundle lives off-disk).
The command prints the new version_id and tx hash. In JSON mode the
output is a single line you can pipe to jq:
Promote (or roll back) the active pointer once you're ready:
2. Attest as an auditor
# Hash the audit report locally, pin it, and emit attestBinaryVersion.
--reportaccepts either a local file (which is hashed; optionally pinned via--pin-report-to-ipfs) or a remote URL (https://...,ipfs://...). When passing a URL, pre-compute the hash and feed it via--report-hash <hex>.--kindis one ofAUDIT,FUZZ,FORMAL,BUG_BOUNTY,SELF.--severitymaps to the on-chain uint8 ladder:none/info/low/med/high/critical.--expires-inaccepts human durations (6m,30d,1y,90d12h); omit for non-expiring.
Other attest commands:
3. Adopt the upgrade as an operator
Set the policy once, then ack each new version under APPROVE:
# Pick a policy: AUTO (follow blueprint owner), APPROVE (opt-in), MANUAL (pin to genesis).
# Opt in to a specific version.
# Inspect what's actually running and how far ahead the upstream is.
upgrade-status prints the policy, the operator's acked version, the
blueprint's active version, the effective version the manager will dispatch
against, and the latest published version — exactly what an operator-facing
dashboard needs.
CI gating: trust score
# Compute the weighted trust score the dapp would render for version 3.
The score walks every non-revoked, non-expired attestation, looks each
attester up in BlueprintAuditors, and produces a normalized 0..=100
number plus per-attestation diagnostics. Without --auditors-contract the
score collapses to zero (all attesters treated as anonymous) — the flag
should always be set in production.
IPFS configuration
Two environment knobs:
# Generic (Kubo / w3up / any service that accepts multipart/form-data + Bearer):
IPFS_API_URL=https://api.web3.storage/upload IPFS_API_TOKEN=eyJ...
# Pinata fallback (only used if IPFS_API_URL is unset):
PINATA_JWT=eyJhbGciOi...
Pin endpoints must return JSON containing one of cid, Hash, or
IpfsHash; the resulting ipfs://<cid> URI is what lands on-chain.
One-command shipping (cargo tangle blueprint ship)
For the common case — "I just landed a feature, build the binary, pin it,
publish the new version, and promote it" — there is cargo tangle blueprint ship.
It composes all the above steps into a single interactive flow:
$ cargo tangle blueprint ship

Auto-detection
The wizard tries (in order) --blueprint-id, BLUEPRINT_ID= in
./settings.env, then blueprintId in ./metadata/blueprint-metadata.json.
It picks the first non-zero value.
CI mode
Skip all prompts with --yes:
In --yes mode the wizard prints one JSON event per phase, with the final
ship_complete event carrying the new version_id, the publish tx, and
whether setActiveBinaryVersion ran. The
tangle-network/blueprint/.github/actions/ship-release
composite action consumes that JSON to populate its outputs.
Common flag matrix
| Flag | Effect |
|---|---|
--yes |
Accept every prompt; switch output to JSON |
--dry-run |
Hash + (optionally) pin + report; submit nothing |
--no-build --binary <path> |
Skip cargo build; ship a pre-built artifact |
--binary-uri ipfs://… |
Skip IPFS pin; assume URI is already addressable |
--no-promote |
Publish but don't setActiveBinaryVersion |
--policy-services 42,43 |
Bulk-flip listed services into AUTO policy |
--attestation-bundle <path> |
Hash the bundle and store its sha256 on-chain |
--attestation-hash 0x… |
Use a pre-computed attestationHash |
Manual-with-assist (operator local-authz)
For operators on MANUAL policy who want the manager to swap into specific
versions but don't want to (a) move out of MANUAL on-chain or (b) spend gas
on ackBinaryVersion, the manager exposes a local authorization layer.
Pre-authorized swaps still run the full sha256+attestation gate — the only
thing the operator is sidestepping is the audit-trail tx.
# List what versions the manager sees on-chain (no chain calls — talks to the
# local manager's /upgrades/{service_id}/available).
# Pre-authorize a single one-shot swap to v3 the next time it becomes effective.
# Stage a fleet-wide rollout: every version in this list is acceptable.
# Explicitly skip v3 (canary regression). Reason lands in the manager's audit log.
# Show what local-authz state the manager is holding for this service.
Manager URL resolution (highest wins): --manager-url → BLUEPRINT_MANAGER_URL
env → http://127.0.0.1:9000. The pre-authorization persists in
<manager-data-dir>/upgrade-authz/<serviceId>.json, so the operator can stage
a pin/whitelist during a maintenance window and walk away — a restart of
the manager rebuilds the state cleanly.
Cloud Commands
Note: Release archives include cloud commands; source installs need the
remote-providersfeature. See Feature flags.
The cloud commands configure providers, quote live prices, and inspect and terminate deployments recorded in the deployment tracker. No CLI command allocates capacity, updates a running deployment or reads its logs, and cargo tangle blueprint run cannot enable the manager's remote deployment path.
Configure Cloud Provider
configure saves a region and default provider. Credentials come from the environment, and for AWS also from ~/.aws/credentials. configure names the variables a provider needs; it never stores a credential. A token can also come from the Compute Engine metadata server for GCP, and from a managed identity or az login for Azure.
# Configure AWS
# Configure GCP
# Configure other providers
Cost Estimation
# Compare costs across all providers
# Estimate a configured provider using its live on-demand price
# GPU-enabled instances
Deployment Policy
# Rank providers for the manager's remote deployments
Monitor Cloud Deployments
status and terminate read the tracker at TANGLE_DEPLOYMENT_TRACKER_PATH, by default ~/.tangle/remote_deployments. Both reach each provider in the region its record names, and a provider that is missing a variable affects only its own deployments. status shows unknown when the provider cannot answer, and status <id> also says why. terminate exits non-zero if any deployment is not confirmed terminated, and that deployment stays tracked.
# Check status of all deployments
# Check specific deployment
# Terminate one deployment
# Terminate every tracked deployment
Preflight and TEE Readiness
# Validate credentials/provider readiness and print manager bootstrap env
# Validate fail-closed TEE readiness (including cryptographic verifier requirements)
# Write bootstrap env directly to file
Spawning a Service Runtime
Kick off the blueprint manager using a specific runtime without re-running the full deploy flow:
The command reuses the same manager wiring as cargo tangle blueprint run, so any RPC endpoint + runtime combo works (VM/native/container). For devnet, omit the overrides and the defaults point at the local harness.
Key Management
All keys are EVM-native. Use the cargo tangle key subcommands to handle k256 material:
# Generate a new operator key
# Import an existing hex secret into the keystore
# List local keys
The keystore supports filesystem, in-memory, and remote HSM backends through blueprint-keystore.
Operator Status
Inspect the latest heartbeat/online status from OperatorStatusRegistry:
Omit --operator to query the locally configured operator. Add --json for machine-friendly output (timestamp, raw status code, online boolean).
- End-to-end demos and advanced options live on the CLI reference.
Managed GPU JSON boundary
With remote-providers (including cloud-only), cloud catalog/quote/create/recover/status/list/destroy/state-init --json
uses the schema version exported by cloud::SCHEMA_VERSION. This source contract
is incompatible with the earlier central draft; an installed binary and its
consumer must be qualified and pinned together. Legacy cloud status [service],
cloud list, configure and tracker termination retain their existing meanings.
JSON status/list cannot be combined with legacy status IDs or watch flags.
catalog --json is offline and reads no stdin or inherited credential/config
settings. Its public output includes the canonical hardware catalog, actual
managed credential variants, generated request/response schemas, schema_sha256
and the input/output ceiling owned by cloud::MAX_JSON_BYTES. Consumers generate
provider/envelope/error types from that pinned output and fail their maintained
build when regenerated output/digest differs. It is not a second hardware or
provider capability table. A descriptor does not promise stock or support for
every request shape.
Other JSON verbs accept exactly one bounded document on stdin, followed by EOF,
and emit one bounded public envelope on stdout. The parser rejects duplicate and
unknown typed fields, excessive nesting, malformed numbers and overflow. Request
schemas describe deserialization, so ResourceSpec.env remains input even though
it is omitted from serialized state. Errors use the SDK's closed
ProviderErrorCode, fixed public text and a nonzero exit. JSON invocations do not
initialize inherited tracing; provider bodies and parser errors are not reflected.
Put credentials in private stdin/vault custody, never arguments or public files.
Requests use a tagged ProviderCredentials array. Quote/create/recover carry the
canonical spec.ownership and spec.lease_duration_secs; there is no second
ownership or TTL field. Status/destroy carry one identity, provider, and a
provider ID (optional for destroy). Destroy retires only an identity this
state_dir authorized under the same account: listed objects of any other
identity, including another store's lease on the same account, are refused with
conflict and left in place. It waits for an in-flight create of the identity
in the same state_dir. List carries namespace and lists the full configured account roster; it has no
provider filter. All operations after quote require state_dir; use the exported
request schemas for the complete field contract. Quote returns the complete SDK
QuoteSet, including failures beside ranked offers. Keep its candidate string
unchanged and preserve the exact original spec, caller public key and account
roster before create. New quote pricing source is the actual HTTP(S) service origin that returned the
offer, without endpoint paths/userinfo/query/fragment. Custom broker origins stay
custom; no default vendor URL or fallback rate is substituted. Invalid or opaque
sources fail before public quote output.
Create opens existing state and calls state-attached create_managed. Its SDK
reservation preserves original quote, account binding, key and deadline before
POST. For an attempted identity, repeated create recovers the original authority
and ignores a replacement candidate; it never re-prices or rents again. A fresh
invalid candidate is refused. recover is no-create and an absent result never
permits re-renting that attempted identity. Keep a caller-owned SSH public key in
the original spec; this public process boundary never exports a generated private
key. Workload environment must be rehydratable under the caller's private custody
for identical recovery; SDK state does not serialize it.
state-init is an explicit, resource-free enrollment of an existing empty,
owner-only, absolute Unix directory without symlink components. Normal verbs
only open it and never repair missing/corrupt state. Central orchestration must
own persistent placement, enrollment markers and a single coherent filesystem
context across calls/restarts. Temporary HOME is not authority. Carry SDK state,
caller records and keys together after stopping the previous writer; independent
copies are not coordinated by local file locks. Keep lost state visible for
operator reconciliation rather than initializing a replacement store.
Non-default QoS is deliberately unsupported rather than silently applied.
Raw TANGLE_GPU_WORKER_TOKEN env is refused, not removed or replaced by an
invented bootstrap variable. Central still owns its maintained one-time bootstrap.
Measured ranking uses the full original private recipe. New candidates clone the
selected arm with only its measurement copies cleared, while the fingerprint
commits the untouched original spec/env/measurements. The SDK validates those
selectors against the canonical original arms. The public MeasurementReceipt
contains only audit hashes, timestamp, counters, concurrency and TP/replica counts;
model/revision/image/raw-result locators are not fields of that response type.
It cannot be replayed as a private execution recipe. This changes the Rust
ProviderQuote.measurement API and requires a containing minor release/adoption,
not a patch compatibility claim. The request schema still accepts full original
private measurement rows and the response schema derives the new receipt.
The SDK reads existing version1 authorization records/full-arm candidates without rewriting them, checking legacy full-arm equality and original key/account/spec and deadline. Newly normalized measured candidates need the new validator; downgrading them to old readers is not supported. Candidate encoding is reversible. Public identifiers, origins and digests remain trusted public metadata, not a general secret-string detector, anonymization guarantee or measurement-truth proof.
Public resources omit raw native instance metadata, env, keys and authorizations,
retain distinct worker/endpoint/SSH URLs and require reported expiry for every
present instance. status is canonical SDK InstanceStatus, with a separate
preempted boolean; Running says capacity is running, not that a workload is
ready. created_at is retained under its canonical name and is not a measured
billing/service start. Central must persist the original absolute expiry in its
existing hard-expiry renewal guard, refuse missing/invalid expiry and never
replace it with a later observation. Preserve original spec separately from
mutable renewal policy. No SDK extension API or second TTL engine is introduced.
Provider observations and inventory remain unverified hardware facts.
The maintained process/HTTP qualification requires an actual SDK827-built legacy
producer and its reviewed source/artifact receipt via D12_LEGACY_PRODUCER and
D12_LEGACY_PRODUCER_RECEIPT. Absence fails the integration parent; it never skips
legacy compatibility. The test helper uses old public APIs to create an actual
fake-provider full-arm quote/private state, then the new binary recovers/retires
it with the same POST count and unchanged record/candidate bytes. This is a source
compatibility fixture, not an installed or paid-provider proof.
