What’s a session key and how does Heima keep it non-custodial❓

Built on ERC-4337, Heima smart accounts are fully onchain and non-custodial by design.

✍️ Session keys act as temporary, scoped signers for the smart accounts. Enabling one-tap trades, delegated actions, and smoother UX without repeated approvals.

You always stay in control:

- The smart account logic defines what the session key can do

- Keys are scoped to a session and can be set to expire automatically

- Everything happens inside a Trusted Execution Environment (TEE) — Heima can’t access the key

- The primary key is never exposed or replaced

You get seamless execution and never give up ownership. 🔓

This is how Wildmeta account logic runs — powered by Heima.
