FAQ
Is the 0.5% AUM fee monthly or annual?
Monthly, on total AUM under management at period start. For $500K AUM = $2,500/month.
When does mainnet activate?
Mainnet is blocked pending an external Soroban contract audit. Funded by SCF Build Grant. ETA: Q3 2026.
Does Nirium custody my funds?
No. The vault is 100% non-custodial. Nirium cannot move your funds without your signatures. It's a technical impossibility at the contract level.
Are Etherfuse fees included?
Yes. The ~0.80% total all-in fee includes both the Nirium software license and the underlying Etherfuse execution costs (including FX MXN/USD). No hidden Stellar spread.
Are there volume discounts?
Yes on Enterprise. For over $5M AUM, the management fee is negotiable. Contact hola@nirium.xyz.
