A task failure, a payment timeout and a failed escrow lock are different events. A task can fail while payment is still pending; a timeout does not prove a payment did not settle; and escrow may not be locked yet. The safe response depends on the payment system’s observable state and retry rules—not simply on whether an agent reports FAIL.
What does “FAIL” tell you—and what does it leave unknown?
The exact-title description available for this topic says that, in one implementation, exhausted attempts after FAIL lock a vault and a later evaluate_escrow_work call returns submission_limit_reached. That is a limited description, not enough to establish what FAIL means, how attempts are counted, how the vault lock works, or what each attempt costs. Those details should not be treated as general payment or escrow behavior.

For a real transaction, separate three questions:
- Did the agent’s work fail? This is a task or evaluation outcome. It does not, by itself, establish the payment’s state.
- Did the payment request settle? A timeout or lost response may leave the result ambiguous. Check the provider’s transaction record or status endpoint before deciding whether to submit again.
- Did escrow lock the funds? Look for the escrow system’s explicit state. Funds might still be in the payer’s wallet, be locked pending assignment, or already be held by a contract.
These states can overlap in time, but one is not proof of another. Record the task ID, payment or operation identifier, request outcome, and escrow state separately.
How should you handle a timeout or ambiguous payment response?
Do not turn an unanswered request into a second business action by default. First determine whether the original action is still being processed, completed, or rejected under that provider’s contract.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
- Keep the original operation identity. If the provider supports idempotency, use the same key for a transport retry of the same logical payment. Do not mint a new key merely because the response was slow or missing.
- Query before resubmitting. Use the provider’s status or transaction lookup with the original identifier. If the provider documents replaying the original result for a repeated request, follow that behavior.
- Act on the returned state. A pending result calls for polling or the provider’s documented notification mechanism. A settled result calls for no second payment. A confirmed rejection may permit a new business action, but only with a new identity if it is genuinely a new action.
- Escalate unresolved ambiguity. If status cannot be determined, preserve the request and response details and use the provider’s reconciliation or support process rather than assuming no charge occurred.
Idempotency behavior is provider-specific. Formance describes deterministic idempotency keys intended to collapse retries, replays and duplicate tool calls into one transaction. AsterPay documents replaying the original result when the same identifier is used with the same signed payload, and returning a conflict if that identifier is reused with a different payload. These examples do not establish a universal guarantee: check the selected provider’s rules for response behavior, key retention and settlement.
What does an asynchronous escrow lock look like?
Execution Market: assignment may still be in progress
Execution Market documents an assignment flow in which an API response of HTTP 202 Accepted with status: assigning means the lock is in progress—not that it succeeded or failed. The documented next step is to poll GET /tasks/{id} or use assignment webhooks. Repeating assignment blindly on that 202 response is specifically discouraged.

In this flow, accepted indicates a successful lock. If the task returns to published, the lock failed or timed out and the task is assignable again. The documented rollback leaves applicants intact. These state names and actions describe Execution Market’s documented implementation, not every escrow service.
Lock timing changes the recovery path
Execution Market describes two timing modes. In its default lock_on_assignment mode, funds remain in the agent’s wallet until assignment; publication alone does not lock them. A published task cancelled before assignment is a no-op in this mode, and a task never assigned before the authorization validity window expires does so without an on-chain refund because funds were not locked. Cancellation after assignment triggers an on-chain refund.

With lock_on_creation, funds are locked earlier. Cancelling before assignment then requires an on-chain refund. The publisher chooses a worker and signs an authorization bound to that worker; the documentation says the receiver is included in the authorization nonce, so the authorization must be created at assignment.
Execution Market describes Solana separately: direct SPL transfers rather than the escrow contract and its on-chain refund path. Do not assume contract-based refund behavior applies to that route.

How do other escrow lifecycles frame failure and refund?
ERC-8183 is a protocol-design comparison, not evidence that a particular product uses it or follows the same workflow. It describes jobs moving through Open, Funded and Submitted, then to terminal Completed, Rejected or Expired states. A client funds escrow, a provider submits work, and an evaluator—either the client or another designated evaluator—completes or rejects it. Rejected or expired work is refunded to the client.
The distinction is useful: submitted work may still be awaiting evaluation; completed work is not the same state as rejected work; and expiry can lead to a refund rather than another attempt. ERC-8183 also specifies that an after-hook runs in the same transaction and can revert the operation, preserving atomicity. It identifies the refund after expiry as a recovery route that a hook cannot block.

What can attempt economics safely tell you?
There is no general retry failure rate or universal cost-per-attempt figure established here. Fees depend on the named service, transaction stage and network. Execution Market’s documentation, accessed in 2026, gives these service-specific examples; they are not industry benchmarks and do not establish the economics of the FAIL implementation described above.
| Execution Market documentation claim | Scope and qualification |
|---|---|
| Approximately 28 seconds facilitator p95 | Described with retries in the discussion of a lock that may take one to two minutes; documentation accessed 2026. |
| 13% platform fee (1,300 basis points) | Execution Market fee figure; documentation accessed 2026. It is not a comparable fee unless the other fee’s scope and transaction stage match. |
| $0.10 bounty: $0.087 to worker and $0.013 to treasury | Execution Market worked example; documentation accessed 2026. The documentation says the worker’s share does not shrink due to the described protocol fee, which is absorbed from the treasury share. |
| $100 deposit cap per task | Execution Market documentation claim; documentation accessed 2026. |
Those figures do not explain whether a failed agent attempt incurs a fee, whether a retry creates another charge, or what happens after a submission limit is reached. For those answers, the relevant implementation must define what counts as an attempt, which operations are billable, when funds are locked or released, and who bears each fee.
What should an implementation check before retrying?
- Task outcome: Is the work failed, submitted and awaiting evaluation, rejected, or expired?
- Payment outcome: Is the original operation pending, settled, rejected, or still ambiguous? What lookup can establish that state?
- Escrow outcome: Are funds unlocked, locking, locked, released, or refundable? Which explicit status confirms it?
- Retry identity: Does the provider require the same idempotency identity for the same action, and what does it return for a replay?
- Attempt policy: What exactly increments the attempt count, what is the limit, and does reaching it stop submissions, lock funds, or trigger another defined action?
- Recovery authority: Who can evaluate, reject, cancel, release funds, or trigger an expiry refund?
- Cost scope: Which charges apply to assignment, locking, evaluation, settlement or refund, and which party pays them?
When these answers are not documented, an agent should not infer them from a generic FAIL label. Treat task status, payment status and escrow status as separate records, and retry only in the way the chosen protocol defines for that state.
