Why this exchange

Non-custodial

We never hold your keys or your funds. Every trade, swap, and transfer is signed and sent by your own wallet, directly on-chain.

DEX-aggregated swaps

Trades route across on-chain liquidity via 0x, so you're not stuck with a single exchange's book or price.

On-chain portfolio

Balances are read directly from-chain, in real time — not a database we could get out of sync with reality.

Fiat on/off-ramp

Buy crypto with a card or bank transfer, or cash out back to your bank, through a licensed ramp partner.

Append-only audit trail

Every account and verification event is logged and never deleted — the same standard compliance examiners expect.

How it works

01

Connect & sign in

Connect your wallet and sign a message to prove ownership. No password, no funds move.

02

Trade, hold, cash out

Swap across DEX liquidity, track your on-chain balances, or move to/from fiat.
