Fees
Every fee is shown on the quote before you sign, and nothing is charged until you confirm in your wallet. This page explains each one.
Bridge (CCTP)
| Bridge amount | Confluence platform fee |
|---|---|
| Up to and including 1,000 USDC | 0.30 USDC |
| Over 1,000 USDC | 0.30 USDC + 0.01% of the part above 1,000 |
The platform fee is added on top of the amount you bridge. The review screen shows the bridge amount, the platform fee, and the total debit: what actually leaves your wallet.
Worked examples
| You bridge | Platform fee | Total debit |
|---|---|---|
| 50 USDC | 0.30 | 50.30 USDC |
| 1,000 USDC | 0.30 | 1,000.30 USDC |
| 1,000.01 USDC | 0.300001 | 1,000.310001 USDC |
| 5,000 USDC | 0.70 | 5,000.70 USDC |
| 100,000 USDC | 10.20 | 100,010.20 USDC |
There’s no jump at 1,000 USDC: the fee grows smoothly from 0.30, by 0.01 USDC for every 100 USDC above 1,000.
Percentage fees are rounded up to the smallest USDC unit (0.000001).
Costs from Circle and the network
These are shown separately on the quote and aren’t Confluence fees:
- CCTP fee (Fast only): Circle’s fee for Fast Transfer. Standard transfers have no CCTP fee.
- Forwarding fee (when Forwarding is on): Circle’s fee for delivering the mint on the destination chain. It’s taken from the amount that arrives, so the quote’s expected receive already accounts for it.
- Network gas: paid by your wallet on the source chain for the approval and the burn, and on the destination chain if you complete a mint yourself. On Arc, gas is paid in USDC.
Pay by Confluence ID
| How you pay | Confluence fee |
|---|---|
| From Arc to an ID | Free |
| From another chain to an ID | The bridge fee above |
A payment from Arc is a single USDC transfer straight to the recipient: you only pay Arc’s network fee, in USDC. A payment from another chain is a CCTP bridge to Arc, so it has the bridge fee and Circle’s costs, all shown on the quote.
Swap
Confluence’s swap fee follows the same rule, applied to the token the fee is taken in (shown on the quote):
- Stablecoins (USDC, EURC, USDT): 0.30 for amounts up to 1,000, and 0.30 plus 0.01% of the part above 1,000.
- Any other token (for example cirBTC): 0.01% of the amount, rounded up to the token’s smallest unit.
Circle’s App Kit route and the network’s gas are shown on the quote as well.
Relay routes
- Confluence fee: a percentage of the value you send, shown on every Relay quote (0.01% by default). The rate on your quote is the one that applies.
- Relay’s own costs, each shown on the quote:
- Execution cost: gas and delivery on the route.
- Swap cost: the cost of any swap within the route.
- Relay platform fee: set by Relay and depending on the route. See Relay’s fee documentation for details.
Always check the total debit or you pay line before confirming. Blockchain transactions can’t be reversed, and that includes fees.
