Crashes, No Sound, or Screen Glitches?

Those are different problems. Find the transaction hash, check its result on the correct network, and use the reported error to decide what to investigate next; a wallet spinner alone does not identify the cause.
First, find the transaction and its actual status
Copy the transaction hash from your wallet or DeFi app and look it up in Stellar Lab’s Transaction Dashboard or an appropriate Stellar API. Confirm that you are checking the network the transaction was submitted to, such as mainnet or testnet. The dashboard can show the hash, source account, sequence number, processing date and fee. For Soroban transactions, it can also expose contract interactions, events, state changes, resource use, signatures and a fee breakdown.
Read the transaction-level result and, when available, the operation result or Soroban diagnostics. A generic “pending” or “failed” message from an app may omit the detail that distinguishes a fee problem from a sequence, signature, balance, trustline or contract issue. Stellar’s RPC sendTransaction response can return PENDING; an ERROR response can include the encoded transaction result that explains why Core rejected it.
Identify which stage the transaction reached
| What you see | What it means | What to check next |
|---|---|---|
| Rejected immediately | Stellar Core rejected an invalid transaction before it was applied. Stellar’s Transaction Lifecycle documentation says an invalid transaction does not increment the source account’s sequence number or consume its fee. | Use the returned transaction result to identify the invalid condition, then correct that specific issue before constructing a replacement. |
| Accepted for propagation or shown as pending | The transaction has not yet been confirmed as included in a ledger. “Pending” alone does not reveal why it has not been included. | Check the transaction’s validity bounds, fee and sequence context; verify its latest status before attempting another submission. |
| Included, but the operation failed | The transaction reached application, but an operation failed. Stellar documents that a failed operation causes the transaction to fail and rolls back its operations. | Inspect the operation result or Soroban diagnostics for the specific failure rather than treating it as a propagation delay. |
Use the error to narrow down the cause
Fee or Soroban resource issue
Fees are paid in XLM. Soroban contract transactions have an inclusion fee and a resource fee; the resource and fee model differs from that of classic transactions. For a contract transaction, use simulateTransaction to calculate the resource values and resource fee needed to construct it. Inclusion fees may need adjustment during congestion, and network resource limits can change, so a generic fee amount is not a guaranteed fix.

Sequence number or an earlier transaction
The source account’s sequence number must be appropriate for the transaction, and only one sequence for a given account can be consumed per ledger. Check whether another transaction from that account was submitted first or is still unresolved. Stellar’s error guidance describes TRY_AGAIN_LATER when another transaction from the same source remains in memory after a low-fee rejection; in that case, wait for it to resolve before resubmitting.
Signature or network mismatch
A TxBadAuth error can indicate a network-passphrase mismatch or insufficient signature weight, according to Stellar CLI troubleshooting guidance. Confirm that the wallet is using the intended network and that the transaction has the required authorization. Do not infer which one is wrong from the error label alone; check the transaction and wallet configuration.

Insufficient XLM, missing account or trustline
Check whether the source account has enough XLM to cover the fee and whether the asset account involved has the required trustline. Stellar’s operational troubleshooting examples also include missing receiver trustlines, underfunding and missing accounts. Those examples describe particular disbursement workflows, however, and do not establish the cause of every DeFi transaction failure.
Expired time bounds or contract-specific failure
A transaction can be invalid if it is submitted outside its allowed time window. For a Soroban transaction, inspect contract diagnostics and resource information for a contract-specific problem; the word “failed” by itself does not establish that the network fee or wallet is at fault.

What to do when a transaction remains pending
- Check the transaction hash again. Look up the current result in Stellar Lab’s Transaction Dashboard or an appropriate API, on the same network used for submission. Do not rely only on the app’s spinner.
- Check its validity window and sequence. Make sure the transaction has not passed its time bounds, and check whether another transaction from the same source account is still unresolved.
- Wait for the bound to expire before replacing it. Stellar’s Soroban debugging guidance says that a transaction not applied within 1–2 minutes is highly unlikely to remain remembered by the network. This is documentation guidance, not a guaranteed confirmation time for every wallet or endpoint. Use client-side time or ledger bounds; after the bound expires, check status before resubmitting.
- If the issue persists, correct the diagnosed cause. For Soroban, simulate the transaction to calculate resource values and resource fees. Consider a fee bump if the problem persists, as the debugging guidance suggests, rather than assuming that repeatedly submitting the same transaction will resolve it.
What information is needed for a specific diagnosis?
A reliable diagnosis of an individual transaction requires its hash, network, wallet, DeFi application or contract, and exact displayed error. Without those details, it is possible to explain the common transaction stages and checks, but not to establish which recovery action applies to that case.
