Why Helio

Built on a simple idea: your money is yours.

True self-custody

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.

Settles in seconds

A routing engine splits orders across venues and chains, so trades clear in under 400ms with minimal slippage — even at size.

Fees in basis points

Flat 0.10% taker, free maker, and gas abstracted away. No spread games, no withdrawal fees, no surprises at settlement.

How it works

From zero to your first trade in minutes.

01

Create a wallet

Generate keys locally with a passkey. No email, no KYC to start, no waiting on approval. You're live in under a minute.

02

Fund any way

Bridge from any chain, transfer from another wallet, or buy with a card. Helio detects and abstracts the network for you.

03

Trade & earn

Swap, hold perps, or stake idle balances. Every position settles to your own keys — withdraw to cold storage anytime.

Security & audits

Audited, open, and impossible to rug.

Non-custodial by architecture

Contracts are immutable and permissionless. There is no admin key that can move user funds.

Real-time proof of reserves

On-chain attestations are published every block and independently verifiable by anyone.

$5M live bug bounty

Continuous adversarial testing with the largest payout tier in the industry, run through Immunefi.

Trusted by

Operators, funds, and builders run on Helio.

"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."

MR
Mara ReyesTreasury Lead, Northgate

"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."

DK
Dev KapoorHead of Trading, Lumen Capital

"Onboarded my whole team in an afternoon with passkeys. No seed-phrase support tickets, no lost funds. It just behaves like software should."

FAQ

Questions, answered.

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.
