Why Oltur

An exchange experience without handing over your keys

Everything an exchange gives you day to day, built on wallets you actually own.

  • 01

    Non-custodial by design

    Your recovery phrase is generated in your browser and encrypted with a passphrase we never receive. We store only the ciphertext, so we can't move your funds or reset your passphrase.

  • 02

    One address, four networks

    The same wallet works on Base, Ethereum, Arbitrum, and Polygon. Switch networks in one click; no separate wallets to manage.

  • 03

    Send in seconds

    Send ETH, USDC, or USDT to any address. Transactions are signed locally and tracked to confirmation with an explorer link.

  • 04

    Works on every device

    Because the encrypted wallet syncs with your account, you can sign in from a laptop or phone and unlock it with your passphrase.

  • 05

    Recover anywhere

    Your 12-word phrase restores the wallet in any standard wallet app. You are never locked in to Oltur.

  • 06

    Swaps and on-ramp, next

    Swap between assets through a DEX aggregator and buy with a card, without giving up custody. In development now.

How it works

Up and running in three steps

No KYC queue, no waiting for approval. Your wallet is ready the moment you create it.

  1. 1

    Create an account

    Email and password. That's your login to Oltur, separate from the passphrase that protects your wallet.

  2. 2

    Create your wallet

    Choose a wallet passphrase and write down the 12-word recovery phrase we show you once. Both stay with you.

  3. 3

    Receive and send

    Share your address to receive on any supported network. Send with your passphrase; we never touch the funds.
