Execution Costs appear in the Estimates panel on every trade. They are not Azura's fee — they represent the real on-chain costs of routing and executing your trade.
What execution costs include
Gas fees — the network fee paid to validators/miners to process your transaction on-chain (e.g., ETH gas, SOL transaction fees)
DEX routing fees — fees collected by the liquidity pools your trade is routed through (typically 0.1% to 0.3% per pool, set by the DEX protocol, not Azura)
Bridge fees — for cross-chain swaps, a small fee is charged by the bridging protocol
How much are they?
Execution costs vary by chain and market conditions:
Solana — very low, usually fractions of a cent
Base / Arbitrum — low to moderate, typically a few cents
Ethereum mainnet — can be significant, especially during high network congestion. For small trades on Ethereum, gas can be a large percentage of the trade value.
Azura Fee vs Execution Costs
Azura Fee = FREE (Azura takes nothing)
Execution Costs = paid to the network and DEX protocols, not to Azura
Minimizing execution costs
Trade on lower-fee chains (Solana, Base) for small amounts
On Ethereum, use off-peak hours when gas is lower
Larger trades are relatively more efficient — fixed gas costs are diluted by trade size
