Rate

Bridg charges only when the aggregation saved you something. The tier is set by how much the chosen route beat the other executable quotes in the same table, measured when the route is decided. A route with nothing to compare against, or one that saved ten bps or less, pays no platform fee: fees.platform is null and every row’s feeBps is 0. 15 bps is the ceiling on the rate.

​
Maximum

The platform fee on one transfer is never more than **10∗∗,whatevertherate.ThecapisconvertedintotheassetyouarebridgingatBridg′sownpriceforit;‘feeAmountAtomic‘isthecappedamount.Areferralshareiscappedat10**, whatever the rate. The cap is converted into the asset you are bridging at Bridg's own price for it; `feeAmountAtomic` is the capped amount. A referral share is capped at 10 separately. See Referrals.

​
How it is charged

  • Taken from the asset you are bridging, on the source chain. Nothing is charged in a second token.
  • Every output in the quote is already net of it. Building a row returns the same amountOutAtomic the quote showed.
  • Disclosed on every quote before anything is signed. A referral share is charged and paid whether or not the platform fee applies:
null means no fee of that kind is taken on this route. It is never a zero-rate fee. Each ranked row also carries its own feeBps, feeAmountAtomic and tierSavedBps, because the tier depends on what that row saved.

​
How it is collected

The build response names the shape in feeCapture. Where a Solana transaction cannot carry the extra instruction, the fee is forgone and feeCapture reads none.

​
Hyperliquid relay

A transfer to Hyperliquid routed through Arbitrum is credited by Bridg’s relayer. The relayer’s cost is a flat amount already off the quoted figure, with nothing extra to approve. See Hyperliquid.
