Helio is a self-custodial wallet and exchange in one. Move across chains, settle in seconds, and pay fees measured in basis points — never in trust.
Spot and perpetual markets across every major asset — quoted with deep liquidity and refreshed in real time.

Keys live on your device, never on our servers. Helio can't freeze, lend, or lose what it never holds. Recover with a passkey or seed — your choice.
A routing engine splits orders across venues and chains, so trades clear in under 400ms with minimal slippage — even at size.
Flat 0.10% taker, free maker, and gas abstracted away. No spread games, no withdrawal fees, no surprises at settlement.
Generate keys locally with a passkey. No email, no KYC to start, no waiting on approval. You're live in under a minute.
Bridge from any chain, transfer from another wallet, or buy with a card. Helio detects and abstracts the network for you.
Swap, hold perps, or stake idle balances. Every position settles to your own keys — withdraw to cold storage anytime.
Contracts are immutable and permissionless. There is no admin key that can move user funds.
On-chain attestations are published every block and independently verifiable by anyone.
Continuous adversarial testing with the largest payout tier in the industry, run through Immunefi.
Over 4,800 tokens across 14 networks, bridged and quoted automatically. No manual network switching, ever.
You see the exact cost before every trade. The price you tap is the price you get.
Maker orders are always free. Volume tiers drop you below 5bps.
Cross-chain swaps cost only the network fee — Helio takes nothing.
Move to cold storage or any wallet whenever you want, free.
"We moved treasury operations to Helio specifically because nobody but us can touch the keys. Settlement is faster than our old custodian and the audit trail is on-chain."
"The routing engine quietly saves us 30-40bps on every large swap. For a desk doing nine figures a month, that's not a rounding error — it's the difference."
"Onboarded my whole team in an afternoon with passkeys. No seed-phrase support tickets, no lost funds. It just behaves like software should."
Your private keys are generated and stored on your own device. Helio never sees them and never holds your assets. Even if our servers vanished tomorrow, your funds remain accessible on-chain with your keys.
You can create a wallet, swap, and self-custody with no KYC. Identity verification is only required for fiat on-ramps and certain regulated regions, and is handled by our licensed partners.
Recovery uses encrypted passkey backups synced to your secure enclave, or a traditional 12-word seed phrase if you prefer. You can also configure multi-device and social recovery in settings.
We don't custody funds, so we carry none of the cost and risk that custodians pass on to users. Our routing engine sources liquidity competitively, and we abstract gas in bulk rather than charging it per trade.
Over 4,800 tokens across 14 networks including Bitcoin, Ethereum, Solana, Base, Arbitrum, Polygon, Optimism and more. Bridging between them is automatic and free of Helio fees.
