Fees, gas and slippage: where the difference goes

Provider fee: the bridge, DEX or solver's margin. Usually a percentage; on SODAX routes 0.1% to the solver and 0% to this interface. Aggregator fee: what the interface charges on top, if anything; Everychain shows it as its own line when non-zero. Gas: paid to the source network in its native token, separate from the amount swapped. Price movement: the market moves between quote and settlement, which is what slippage tolerance protects against.

The amount shown as 'you receive' has the provider fee and any aggregator fee taken out. It does not include gas, which is paid separately and shown as the token you pay it in. It also does not include price movement, because that has not happened yet.

Slippage tolerance, default 0.5%, sets the floor. Minimum received is the quoted amount less that tolerance; the transaction is built so that if the market moves further than this before settlement, it fails rather than filling at a worse rate. For an intent, this floor is written into the intent itself; a solver who cannot meet it does not fill.

Lowering tolerance reduces the worst case but raises the chance of a failure and a wasted gas payment. For stablecoin corridors 0.1 to 0.3% is reasonable; for volatile pairs on slow chains, 0.5 to 1%.

Liquidity is finite at every venue. A $100 transfer barely moves a pool or a solver's inventory; a $10,000 one does. Measured on SODAX stablecoin corridors the all-in cost is about 0.01% between $100 and $1,000 and rises past $5,000; above roughly $30,000 there may be no route. Bridges with deep pools cost a flat 0.2 to 0.3% and hold that to larger sizes. The crossover is the reason routes are compared per quote rather than ranked once.
