OpenHelix Docs

Everything you need to create and manage tokens with OpenHelix Studio — no code required.

Introduction

OpenHelix is a browser-based Web3 toolkit. From the Studio you can create tokens, lock tokens/LP, set up vesting, and verify contract source — across several EVM chains and Solana. You sign every action in your own wallet; OpenHelix never holds your keys or funds.

Getting started

You need three things:

A wallet extension — MetaMask for EVM chains, Phantom for Solana.
A little of the network's native coin for gas (free on testnets via a faucet).
The Studio open in your browser. Open the Studio →

Always practice on a testnet first. Testnets behave like the real chains but use free, valueless coins, so you can do a full dry run before spending anything.

Connecting a wallet

Pick your network from the dropdown in the top-left of the Studio.
Click Connect Wallet. EVM networks prompt MetaMask; Solana networks prompt Phantom.
Approve the connection. The button shows your shortened address when connected, and the status dot turns green.

Switching to a network of the other type (e.g. from BNB to Solana) will ask you to reconnect with the matching wallet.

Supported networks

Family	Testnet	Mainnet
BNB Chain	BNB Testnet	BNB Smart Chain
Ethereum	Sepolia	Ethereum
Base	Base Sepolia	Base
Arbitrum	Arbitrum Sepolia	Arbitrum One
Optimism	OP Sepolia	Optimism
Polygon	Amoy	Polygon
Avalanche	Fuji	Avalanche
Solana	Devnet	Solana

Token creation is available on all of them. Locking, vesting and verification have network limits — see those sections below.

Creating a token

Open the Create Token tab, fill in the form, and deploy:

Name — the full display name (e.g. "OpenHelix Demo").
Symbol — the ticker (2–6 characters).
Decimals — how divisible the token is. 18 is standard on EVM; Solana allows 0–9.
Total supply — whole tokens, minted in full to your wallet at creation.

Click Deploy Token and approve in your wallet. On success you get the contract/mint address, an explorer link, and (on EVM) an "Add to Wallet" button.

EVM vs Solana

On EVM chains, each token is its own ERC-20 contract. On Solana, the token is an SPL mint created through Solana's Token Program — there's no per-token contract to deploy.

On mainnet, creating a token spends real gas (or SOL for rent). Do a free testnet run first to confirm the flow in your wallet.

Locking tokens / LP

The Lock tab time-locks any token (including LP tokens) until a date you choose — a common trust signal for investors. Deploy a locker once (or paste an existing one), enter the token, amount and unlock date, then approve and lock. After the unlock time you can withdraw by lock id.

Available on test networks today. Because this contract safeguards real funds, it goes live on mainnet once its security audit is complete — a standard step we take seriously. (EVM feature; not applicable to Solana.)

Vesting

The Vesting tab releases tokens to a beneficiary gradually over time, with an optional cliff. Deploy a vesting contract, set token, beneficiary, amount, start, cliff (days) and duration (days), then approve and create. The beneficiary calls Release to claim what has vested.

Available on test networks today. Like locking, it handles real funds, so it ships to mainnet right after audit.

Verifying source

The Verify tab publishes your token's source code on the block explorer (the "Verified" badge), so anyone can read exactly what it does. Paste a free Etherscan API key (works across EVM chains), confirm the constructor values, and submit.

Verification is an EVM/explorer feature. Solana SPL tokens use on-chain metadata (Metaplex) instead, so this tab is EVM-only. If your browser blocks the call (CORS), use the repo's verifier service, which does the same job reliably.

Security & safety

Your keys stay yours. Every action is signed in your wallet. OpenHelix never sees your seed phrase or private key — and you should never paste it anywhere.
Use a dev/burner wallet while testing.
Testnet first, always. Confirm the whole flow for free before touching mainnet.
Audits before mainnet money. Fund-holding contracts (lock, vesting) need a professional audit before they go live with real value.
Not legal or financial advice. Launching tokens or raising funds can carry legal and tax duties that vary by country — consult professionals.

Troubleshooting

"No wallet found"

Install MetaMask (EVM) or Phantom (Solana), then reload the page.

"Wrong network"

The Studio tries to switch your wallet automatically; if it doesn't, approve the network-switch prompt, or add the network manually in your wallet.

Transaction fails or "insufficient funds"

You need the network's native coin for gas. On testnets, get free coins from that network's faucet and try again.

Something else

Check the Activity log at the bottom of the Studio — it shows the exact error message, which is the fastest way to diagnose the issue.
