Opengradient fees
Fees are not published on the bridge homepage. Review any costs displayed in the interface and your wallet before confirming a transfer; network fees may also apply.
Is Opengradient safe?
The bridge states that it does not take custody of funds, but this does not remove smart-contract, network or cross-chain messaging risks. Transfers are irreversible, and the project warns users to verify network, address and amount before confirming.
Audit details for the bridge are not published on its homepage. The homepage also disclaims warranties and liability for losses related to user error or underlying protocols. Treat transfers as high risk until you have independently checked the route and transaction details.
