Not all products support Tonkeeper or other TON-based wallets natively. You may need to bridge or connect an Ethereum-compatible wallet such as MetaMask. Wallet support, delegation, claim flows, and other account features are controlled by the third-party product, not by STON.fi.
For Ethena specifically:
- Documentation: docs.ethena.fi
- FAQ: docs.ethena.fi/resources/faq
For wallet-support, delegation, or rewards questions, contact the support team of the third-party product you're using — they're the canonical source for their own product.
