Yield.xyz vs Zyfai
Yield.xyz is yield infrastructure. One API covers staking, lending, and vaults across many networks, and it returns the transactions for your stack to sign.
The breadth is the point. You discover an opportunity, ask for enter, exit, or manage, and you submit the transactions yourself. The position lives in the wallet you already have. Signing and custody stay yours.
Zyfai is the layer after that first transaction, and the security monitoring is part of it. Yield.xyz returns the transactions. It does not watch the position afterwards, and it does not constrain what a session key is allowed to call. On Zyfai that monitoring is run by us: the position stays inside a whitelist, a session key cannot send funds to an arbitrary address, and an agent keeps allocating and exiting when the risk changes.
A fit for Zyfai when
- You want the position monitored after the deposit, not only a transaction to sign.
- Execution should stay inside a session key that cannot redirect the funds.
A fit for Yield.xyz when
- You want one API over a wide yield catalog, and your own signer.
- The wallet, the policy, and the execution already exist in your stack.
