UTXO - Minimum Relay Fee
In UTXO chains (like Bitcoin), the minimum relay fee is the lowest fee per kilobyte (KB) that a node will accept to propagate a transaction across the network.
When a transaction is rejected due to being below the minimum relay fee, it will fail to broadcast across the network. To resolve this, you will need to resubmit the transaction with a higher fee that meets or exceeds the minimum relay fee. This ensures that the transaction can be propagated and eventually included in a block.
Common Relay Fees for UTXO-Based Blockchains
The following table shows the typical relay fees for various UTXO-based blockchains:
| Blockchain | Relay Fee | Unit |
|---|---|---|
| Bitcoin (BTC) | 0.00001 | BTC (10 satoshis/byte) |
| Litecoin (LTC) | 0.00001 | LTC (10 litoshis/byte) |
| Bitcoin Cash (BCH) | 0.00001 | BCH (10 satoshis/byte) |
| Dash (DASH) | 0.00001 | DASH (10 duffs/byte) |
| Zcash (ZEC) | 0.00001 | ZEC (10 zatoshis/byte) |
| Dogecoin (DOGE) | 0.001 | DOGE (default) |

Chains without Relay Fee
Chains that do not rely on the UTXO model, such as Ethereum (ETH) and most other smart contract platforms, do not have a "relay fee." They use an account-based model and operate with a gas system to prevent spam and allocate computational resources.
