My withdrawal is stuck in the mempool — what now?
Almost always self-resolves within 6 hours when fees normalize. Our auto-bumper re-broadcasts with a higher fee if it sits too long.
What's happening
After Cinoslots broadcasts your withdrawal, it lives in the mempool (the queue of unconfirmed transactions) until a miner/validator includes it in a block. If your transaction's fee is too low for current network conditions, it can wait a long time.
Our auto-bumper
We monitor every withdrawal we've broadcast. If a transaction sits in the mempool with no confirmations after 1 hour, we automatically re-broadcast it with a 50% higher fee (using BTC's RBF — replace-by-fee — or ETH's nonce-bump). This usually unsticks it.
If the second attempt also fails after another hour, we escalate to a third bump. Total worst-case wait: 6 hours, after which the transaction is virtually guaranteed to confirm.
Can I see this happening?
Yes. Profile → Transactions shows every TX hash for a single withdrawal — you'll see the original and any auto-bumped replacements. The latest one is the canonical version.
What if it's been 24+ hours?
Contact support with the withdrawal ID and the latest TX hash. We'll investigate in the priority queue. Common rare causes:
- A node-side issue with our broadcasting infrastructure (we have multi-region failover, so this is uncommon)
- A persistent mempool eviction loop on Bitcoin during sustained congestion — we manually re-broadcast through a different relay
What you should NOT do
- Don't contact a "transaction accelerator" service offering to push your TX to miners for a fee. They're scams in 99% of cases. Our auto-bumper does the same thing for free.
- Don't try to "cancel" a broadcast TX from your end. The transaction belongs to our hot wallet — only we can manage it.
- Don't double-spend it from your wallet — only Cinoslots holds the keys to the source address.
Avoiding mempool stuck-ness
- Use USDT TRC20 (no mempool concept; near-instant)
- Use BNB / BEP20 (3-5 sec finality)
- Stick to BTC/ETH withdrawals during off-peak hours
A note on Lightning
We don't currently support Lightning withdrawals for BTC. It's on the roadmap for late 2026.

The network fee on my withdrawal looks really high — what's going on?
Ethereum gas spikes during congestion. Use USDT TRC20 (flat ~1 USDT) or BTC (lower at off-peak hours) to avoid this.
What do the different withdrawal statuses mean?
Pending → Approved → Broadcast → Confirming → Completed. Each step is shown live in Profile → Transactions.
My withdrawal failed — what now?
Auto-retried up to 3 times before alerting support. If permanently failed, balance is restored and a ticket is opened automatically.
