Build the agent as a constrained planner, not an autonomous key holder. The model should propose an allowed action; ordinary application code should validate that proposal, construct a deterministic Sui programmable transaction block (PTB), obtain the right approval, sign with a controlled key, submit through a currently supported Sui interface, and verify the resulting effects before reporting success.
Start on a local or other non-production network. Use the Mysten Labs TypeScript SDK for the first implementation, keep signing authority outside the model, and move privileged production keys to multisig or hardware-security-module custody. This separation makes failures observable and limits what a prompt, model error, or compromised service can do.

The architecture: proposal, policy, transaction, authority, result
A safe Sui agent has distinct stages. Combining them in one model call makes it difficult to audit what was requested, what was signed, and what actually executed.

- Policy validation: application code checks that the intent is permitted for this user, network, object type, Move target, amount, and current state.
- PTB construction: deterministic code translates the approved intent into a small programmable transaction block.
- Authorization: a human or service policy approves the exact transaction summary; a signer produces the signature without exposing private-key material to the model.
- Submission: the signed transaction and signature go to a Sui endpoint that supports the selected network and API.
- Verification: the application reads status and effects, confirms the expected object and balance changes, and only then tells the agent or user that the operation succeeded.
Sui PTBs can combine Move calls, object transfers, and coin operations. A result produced by one command can be consumed by a later command in the same block, and the block executes atomically: if a command fails, the transaction’s effects are rolled back. The PTB documentation explains the command and result model.

Choose the SDK and environment
Start with the TypeScript SDK
The Mysten Labs TypeScript SDK supports network queries, transaction construction, signing, submission, and interaction with a local network. It is distributed as the ESM package @mysten/sui. The current installation command in the SDK documentation is:
npm i @mysten/suiKeep the SDK version pinned in your application and review its release notes before upgrading. API names and supported transports change over time, so use the documentation for the version installed in your lockfile rather than copying an old example. The SDK entry point is Mysten Labs’ Sui TypeScript SDK documentation.
Free tools Windows power users keep installed
One-click scans. No signup required.
Other language SDKs may be appropriate for an existing service, but support and feature parity vary. Sui’s SDK reference distinguishes the official SDK surface from community-maintained options; confirm that the language and version you choose support the transaction, signing, and transport features your agent requires.
Use three environments deliberately
| Environment | Use it for | Credentials and data |
|---|---|---|
| Local network | Deterministic development, contract integration, and failure tests | Disposable keys and locally created objects; never production value |
| Non-production network | Endpoint integration, wallet/signing integration, and realistic multi-service tests | Separate non-production keys and test assets |
| Mainnet | Release validation after policy, signing, and effect checks pass elsewhere | Dedicated production keys, least privilege, and approval controls |
The SDK documentation supports interaction with a local network. The Sui CLI cheat sheet documents sui start for starting a local network and sui move test for Move project tests; see the Sui CLI Cheat Sheet. The Getting Started and developer documentation pages provide the current setup path.

Constrain what the model is allowed to request
Do not let a model emit arbitrary Move targets, object IDs, recipient addresses, or serialized transaction bytes. Define an application-level action schema and reject anything outside it. A narrow first agent is easier to test than a general wallet operator.
Define an explicit intent schema
For example, an intent could contain:
action: an enumerated operation such assend_assetorcall_whitelisted_method.network: an exact environment identifier; do not infer it from a prompt.assetTypeor an approved object class.objectId, when the operation acts on a specific object.recipient, validated as a Sui address and checked against an allowlist or user policy.amount, represented as an integer in the asset’s smallest unit rather than a floating-point number.reasonand an expiry or request identifier for audit records.
Reject missing fields, unknown fields, malformed addresses, negative or fractional amounts, and requests for a network different from the configured signer. Treat model output as untrusted input, even when it is valid JSON.
Apply policy before constructing a PTB
- Allow only registered Move package, module, and function targets.
- Allow only object types and object IDs that the service owns or has explicitly delegated.
- Enforce per-transaction and rolling-period spending limits.
- Require an approval step for new recipients, high values, shared objects, or administrative methods.
- Check that the signer role is authorized for the requested action.
- Bind the request to one network and one environment; never reuse a Mainnet key on a test environment or vice versa.
- Record the policy decision, the normalized intent, and the identity that approved it.
These are application controls derived from the transaction and signing model, not a substitute for Move-module authorization. The Move package and the signer must still enforce their own permissions.
Construct a deterministic programmable transaction block
Use the SDK’s Transaction API to express a small, reviewable command sequence. The same validated intent should produce the same transaction shape, apart from values such as gas selection that the SDK supplies. Avoid allowing the model to assemble command arrays directly.
Typical PTB building steps
- Load the approved intent and re-check its network and policy decision.
- Resolve current object ownership and state. If an object changed since planning, stop rather than silently substituting another object.
- Create a transaction object with the SDK.
- Add only the whitelisted Move calls, transfers, and coin operations needed for this action.
- Pass results from an earlier command to a later command only where the operation requires it.
- Set the intended sender and allow the SDK to estimate gas and select eligible coins.
- Produce a human-readable summary containing the sender, target, object IDs, recipient, amounts, gas budget or estimate, and network.
The SDK transaction-building guide covers the current transaction API. PTBs and their command-result model are described in the Sui documentation.

Illustrative construction pattern
const intent = await planner.propose(userRequest);
const approved = policy.validate(intent, session, network);
if (!approved.ok) throw new Error(approved.reason);
const tx = new Transaction();
// Add only the Move call or transfer corresponding to approved.action.
// Resolve and validate object IDs in application code; do not accept
// arbitrary targets or serialized bytes from the model.
const summary = summarize(tx, approved.intent);
await approvalGate.require(summary);
// Build, sign, submit, and inspect effects using the current SDK client.This is a design pattern, not a promise that every SDK release has identical helper names. Check the installed SDK’s transaction and client references before production use. Keep construction code deterministic and unit-testable: given a fixed intent and mocked chain state, it should create the expected command sequence or reject the request.
Estimate gas, sign, and submit
Sui’s documented high-level path is to build transaction data, estimate gas and select coins, sign the transaction, then submit the transaction together with its signature. The Signing and Sending Transactions documentation describes this flow.
- Build: create the PTB from validated application data.
- Resolve gas: query the configured network and let the SDK select suitable gas coins, or apply an explicit, tested selection policy.
- Review: render the exact normalized transaction summary. A user approval should cover the transaction that will be signed, not merely the original natural-language request.
- Sign: call a signer service, wallet, multisig process, or hardware-backed signer. The model receives no private key and should not receive an unrestricted signing callback.
- Submit: send the transaction bytes and signature through the SDK client or approved transport.
- Persist: store the request ID, transaction digest when returned, signer role, network, and policy decision for later reconciliation.
A submission response means the endpoint accepted the request; it is not yet proof that the intended state change occurred. Network timeouts also do not prove failure. Reconcile by digest and inspect the chain before deciding whether to retry.
Choose a current Sui transport
Transport compatibility is time-sensitive. The Sui SDK reference reports that JSON-RPC was disabled on Foundation Mainnet during the week of July 27, 2026, and directs developers toward gRPC or GraphQL. Do not copy an older JSON-RPC Mainnet example into a new integration without checking the current status. See Sui and Community SDKs.
| Decision axis | What to verify |
|---|---|
| Interface | Whether the selected SDK client supports gRPC or GraphQL for the target network; avoid assuming a legacy JSON-RPC endpoint remains available on Foundation Mainnet. |
| Capabilities | Transaction submission, effects and status queries, object reads, pagination, and any subscription or polling behavior your agent needs. |
| Limits | Rate limits, payload limits, timeout behavior, authentication requirements, and the provider’s terms. |
| Operations | Uptime, regional routing, observability, incident communication, and a tested fallback plan. |
| SDK fit | Exact package version, transport adapter, and feature parity with your language and deployment. |
The available documentation establishes the interface migration and the category of supported providers, but it does not establish a particular vendor recommendation. Select an endpoint only after testing it against your query and submission workload.

Verify effects and handle failures
Sui’s transaction lifecycle documentation describes certified effects as proof of settlement finality and the transaction as irreversible. Your agent should therefore report success only after checking the execution result and effects, not merely after receiving a digest. Read the Life of a Transaction documentation for the lifecycle terminology.
What to verify
- The transaction reached the expected final status rather than an execution failure.
- The sender and network match the approved request.
- Expected object versions, ownership, balances, or emitted events changed as intended.
- No command-level error or Move abort occurred.
- Any dependent action uses the verified resulting object or state, not an assumption based on the request.
Classify errors before retrying
| Symptom | Safe response |
|---|---|
| Policy rejection or malformed intent | Do not retry automatically. Return a correction request or require a new approval. |
| Insufficient gas, missing object, or stale object version | Refresh chain state, re-plan, and obtain approval again if the transaction changes. |
| Move execution failure | Record the abort and inputs. Do not resubmit the same action blindly. |
| Transport timeout after submission | Look up the request or digest and inspect effects before considering a retry. |
| Endpoint unavailable before submission | Fail closed or use a separately tested endpoint; preserve the exact unsigned transaction and approval context. |
The lifecycle documentation discusses idempotence in the context of pending-transaction handling. Do not generalize that statement into a guarantee that an arbitrary multi-step agent workflow is idempotent. Make each workflow step explicitly deduplicable with your own request ID and reconciliation record.
Test from local execution to production-like integration
1. Test Move packages independently
Run sui move test for contract-level behavior, including successful calls, authorization failures, invalid objects, and boundary amounts. These tests do not exercise the model, policy service, signer, endpoint, or effect-verification code.
2. Run a local Sui network
Use sui start to start a disposable local network as documented in the CLI cheat sheet. Seed test accounts and objects, then run the complete agent path against that network. Reset the network between scenarios so tests do not accidentally depend on leftover state.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
3. Test the planner and policy boundary
- Give the planner ordinary requests and assert that the normalized schema is valid.
- Fuzz malformed JSON, unknown actions, huge values, alternate address formats, and prompt-injection attempts.
- Verify that a model suggestion for an unapproved Move target is rejected before PTB construction.
- Check that network, signer role, recipient, object type, and spending limits are enforced independently of the model’s explanation.
4. Test PTB construction
Snapshot or otherwise inspect the generated command sequence for each allowed action. Assert that the sender, targets, object IDs, recipients, amounts, and number of commands match the policy decision. Include a test proving that changing a rejected field cannot alter the transaction.
5. Test signing and submission
Use disposable keys and a non-production endpoint. Exercise signer denial, unavailable signer, expired approval, duplicate request IDs, gas-selection failure, endpoint timeouts, and responses that arrive after a client timeout. Confirm that private-key material never appears in model prompts, logs, traces, or error messages.
6. Test effects and recovery
For every successful case, assert the expected post-transaction objects, balances, or events. For failures, assert that the agent does not claim success and that a retry path first reconciles the original digest. Include interrupted-process tests between signing, submission, and effect polling.
7. Use a non-production network for integration
After local tests pass, run the same service against a non-production network with separate credentials and realistic endpoint limits. Validate deployment configuration, secret injection, monitoring, rate-limit handling, and upgrade procedures before enabling any production signer.
Protect signing authority in production
The model should never see raw private-key material or have unrestricted access to a signer. Sui’s signing guidance recommends separating production keys by role and network and placing privileged keys under multisig or hardware security module custody rather than a hot keystore; see Signing and Sending Transactions.
Separate roles and networks
- Use distinct keys for development, testing, operations, treasury, and administration.
- Use distinct keys for each network and environment.
- Give the agent only the minimum role needed for its allowed actions.
- Keep administrative or upgrade authority outside the agent’s signing path.
Put high-impact authority behind controls
Use multisig or hardware-backed custody for privileged operations. A hot service key may be acceptable for a narrowly limited, low-value action after a risk review, but it should not be the default for treasury or administrative transactions. Enforce amount limits and approval escalation in code, and monitor every signed request.
A practical release checklist
- The agent emits a typed intent, not transaction bytes.
- Policy code validates targets, objects, recipients, amounts, network, signer role, and expiry.
- PTB construction is deterministic and covered by tests.
- Gas estimation and coin selection are exercised on the chosen network.
- The approval screen shows the exact transaction summary to be signed.
- The signer is isolated from the model and logs do not contain secrets.
- The endpoint uses a currently supported interface, with gRPC or GraphQL checked for Foundation Mainnet after the July 2026 JSON-RPC change.
- Submission records a request ID and transaction digest.
- Success requires verified status and expected effects.
- Timeout and duplicate paths reconcile before retrying.
- Local, non-production, and production credentials are separate.
- Privileged production authority uses multisig or hardware custody.
This sequence gives you a narrow, testable agent first. You can add actions only by extending the schema, policy rules, PTB builder, and test matrix together; do not broaden authority merely by changing the model prompt.
