What should my address look like?

A blockchain address is a unique string of characters, usually in a hexadecimal format of numbers & letters.

These strings represent a public address used by a blockchain to identify participants.

On Ethereum and most EVM-compatible networks like BSC, addresses start with 0x.

Example: 0x1871464F087dB27823Cff66Aa88599AA4815aE95 (Galxe OAT Contract)

Sending Transactions on Galxe

If you need to send transactions, ensure you have some crypto to cover the network fees.

As soon as a block is confirmed, transactions get completed.

The network state changes to reflect the transactions, and accounts are adjusted.

In most cases, your wallet won't let you send a transaction that will fail, and it will tell you if it may not be successful.

A network consumes the transaction fees— you are competing with others and paying for valuable block space.

Because of this, you will not get a refund from network fees unless it's returned by the network as unconsumed units of gas.

ℹ️ Note: Check your wallet for warnings and be cautious when transactions are excessive in cost. (Gas estimation error)

Be careful, nothing can be done about network fees if you send a failed transaction.
