Get iUSD.
iUSD is the dollar you trade with on ONIX. Every unit exists because someone deposited a real dollar into a published reserve, and every unit can be cashed back out through the same door, anytime.
Moving in or out is one signature — no gas, no forms, no chain switching. The bridge charges 1% on the way in and 5% on the way out, quoted as exact figures before you sign: deposit 100.00 USDC and receive 99.00 iUSD; burn 100.00 iUSD and receive 95.00 USDC. Instant credit and instant payout run up to published limits, stated in the widget below; above them, a person reviews.
1Move dollars
This is the bridge exactly as it will work, with the controls switched off: iUSD is not on Arc yet, so there is nothing to sign and nowhere to send. No balance, quote or address on this page is real until it opens.
One signature on Base moves the dollars. You never pay a network fee, on either chain.
2The terms
Cashing out is the second tab above, and it is always open. The iUSD you cash out is destroyed on the spot — that is the receipt — and dollars return to the same wallet on Base, minus the 5% cash-out fee, quoted as an exact figure before you sign: burn 100.00 iUSD, receive 95.00 USDC. Payouts the desk float can cover are paid automatically within minutes; the rest the desk pays from the reserve within hours — the same amount either way. The widget says which one you are getting before you sign. No waiting period, no questions.
Do not transfer iUSD to us by hand to cash out. It has to be destroyed for the count to stay honest, and a plain transfer is not that. If you have already sent one, write to support — the footnote below — and it is put right.
iUSD is issued by the ONIX team, and only when a deposit comes in — never out of thin air. The deposits sit in a wallet we publish, so anyone can compare what we hold against the iUSD in circulation. Bridge fees are retained in that same reserve, so the backing only grows relative to circulation — the split between required backing and fee surplus is itemized, with the rest of the disclosure, on Transparency.
a dollar in stays a dollar held. the ledger is public, the reserve is one address, and anyone can do the subtraction.
