Tandem Back to home

Delegated trading, without handing over the keys to the vault.

Withdrawals are impossibleTandem refuses any API key that can transfer funds, and has no transfer code path at all.
Keys never leave the serverEach key is sealed with its own AES-256-GCM data key; only the server can decrypt it.
Everything is auditedEvery rule decision, order and permission change lands in an append-only, hash-chained log.
