A small widget fee is automatically applied to any bridge transaction made using the LI.FI Widget in the Safe{Wallet} UI and paid to LI.FI. A part of this fee is then paid to Safe Ecosystem Foundation as a license fee to support Safe community initiatives. In this article, we’ll explain in detail how these fees are calculated.


Fee tiers

Tiered fees for all token pairs (excluding stablecoin-only pairs)

Example: ETH to USDC

Trade Size (USD)

>100,000 – 1,000,000

>1,000,000

0.10%

Tiered fees for stablecoin-only pairs (USDC/USDT/DAI)

Example: USDC to DAI

Trade Size (USD)

Applied Fee

0 – 100,000

0.10%

>100,000 – 1,000,000

0.05%

How the fees are applied

The widget fee is always applied to the initial asset being bridged. When you initiate a bridge transaction (for example, sending 1,000 USDT from Ethereum to Polygon), the fee is taken from the amount you send. The exact percentage to be charged is always known and displayed to you before confirming the transaction.

Example:

If you bridge 1,000 USDT with a 0.1% widget fee, 1 USDT will be collected as the fee, and 999 USDT will be sent across the bridge (excluding additional network fees).

Additional costs

In addition to the widget fee, users may incur

  • Network fees: Gas costs for executing the bridge transaction on the source and destination chains

Key points

  • The widget fee is deducted from the asset you are sending (input token), not from any surplus or output token.

  • The percentage rate is always displayed upfront before you confirm the transaction.

  • This structure ensures transparent and predictable fee collection for all bridge transactions using the LI.FI Widget on Safe{Wallet}.
