# Network fee

> The fee a blockchain charges to record a transaction. Who pays it on incoming crypto payments, and how CryptoLike reserves and charges it on payouts.

The amount a blockchain charges to include a transaction in a block, paid to its miners or validators in the chain's native coin.

## How it works in CryptoLike

On an incoming CryptoLike payment, the payer's wallet sets and pays the fee of the transfer it sends, and the payment expects `payer_amount` to arrive at the address. When a customer pays from an exchange that deducts its withdrawal fee from the amount, the transfer can arrive short; a shortfall beyond the tolerance (0.5 % by default) makes the payment [underpaid](https://cryptolike.net/glossary/underpaid-payment). The network fee is separate from the CryptoLike [platform fee](https://cryptolike.net/glossary/platform-fee).

On a payout, `POST /v1/withdrawals/estimate` returns the platform fee, the reserved network fee and `total_debit` before you confirm. The reserve is the network's estimate with no mark-up, expressed in the coin of the payout; for a token it is converted into that token. What you are charged is set by the platform for your account (`network_fee_mode`), not chosen per payout: by default exactly the reserved estimate; in the `actual` mode the fee actually paid, and the unused reserve returns to `available` on completion. The completed withdrawal shows it in `network_fee_charged`. Without an estimate, CryptoLike does not create the payout — retry later.

## What drives the fee on each network?

The network fee is set by the blockchain, not by CryptoLike, and each network CryptoLike supports measures it differently. The table sums up the public rules; the current platform fees are on the [pricing page](https://cryptolike.net/pricing):

| Network | What the fee depends on | Paid in |
|---|---|---|
| Bitcoin, Litecoin | transaction size in bytes and demand for block space | BTC, LTC |
| Ethereum (ETH, ERC20) | gas used by the transaction and the gas price | ETH |
| TRON (TRX, TRC20) | energy and bandwidth; TRX is burnt when the sender has none | TRX |
