Transactions

This section explains how they work, how to manage pending transfers, and what to watch out for with different blockchains.

---

Every blockchain transaction requires gas (a network fee). Fees depend on network congestion and chain rules. Small transfers can be uneconomical during peak congestion; consider waiting or using a lower-fee chain.

Blockchain transactions are final once broadcast/confirmed. You generally cannot cancel them. If you send to a wrong address or unsupported network, funds are typically unrecoverable. Double-check chain, address, and any required memo/tag before sending.

Pending transactions & speeding up

• Bitcoin (UTXO): Speed-ups require the original tx to be flagged “replaceable” (RBF) and a higher-fee replacement. If not RBF, you must wait for miners or try CPFP (advanced).
• EVM chains: You can “speed up” or “cancel” by sending a same-nonce transaction with a higher max fee. Actual success depends on timing/miners.
