Your wallet,your rules.
Cryptonexxs is built around the wallet you already use. We never ask you to deposit funds, never hold a balance, and never have access to your private keys. You stay in control from the first quote to the last confirmation.
You hold the keys
Connect any non-custodial wallet — MetaMask, Phantom, Trust, Ledger, Trezor or a mobile wallet via WalletConnect. Your private keys never leave your device.
Transparent balances
See every asset you hold, its current value and the network it lives on. No hidden positions, no surprise tokens.
Swap in place
Move from one chain to another without first sending funds to an exchange. Pick a pair, sign once, done.
On-device signing
Every transaction is signed by your wallet. Cryptonexxs never has custody and never has the ability to move your funds.
60+ networks
Ethereum, Bitcoin, Solana, Base, Arbitrum, Polygon, BNB, Tron, TON and more. New networks are added as liquidity allows.
Reserves at a glance
A live reserves panel shows the assets we can route through, so you always know what is available before you commit.
How a swap works
Connect your wallet
Pick from the wallet options on the exchange. We support browser extensions, mobile wallets and hardware devices.
Choose a pair
Search 1,200+ assets. The rate, fee and arrival time are quoted live as you type.
Sign the deposit
Your wallet pops up. Review the destination address, the amount and the network fee, then approve.
Receive the swap
Cryptonexxs routes the trade through liquidity partners and sends the destination asset straight to your wallet.
Works with the wallet you already trust
Cryptonexxs is wallet-agnostic. If your wallet speaks WalletConnect, EIP-1193 or Solana Wallet Adapter, it works here. No new app to install, no seed phrase to write down.
A note on security
No custody, ever. Funds move directly between your wallet and our liquidity partners. We do not hold deposits, balances or float.
Audited partners. Swap routing is provided by ChangeNOW, a regulated exchange with a public security track record and ongoing third-party audits.
Verify before you sign. Every wallet prompt includes the destination address and the exact network fee. If something looks wrong, reject the signature.
Connect a wallet and swap
Bring your own wallet, pick a pair and we will handle the routing. No account required.
