How Gasless Works

$0 network fees. Just sign the trade.

Trades on Neptune settle on Solana with zero network + priority fees on your side. You don’t need SOL for gas; you just sign. Protocol trading fees and spreads still apply.

Step 1

You sign

Approve the trade in your wallet. No SOL needed for gas.

Step 2

Network fee: $0

The network fee is handled under the hood; you don’t pay for tx fees.

Step 3

Tx lands

The transaction confirms on Solana and updates your position.

Step 4

Receipt issued

Proof Page + on-chain receipt so anyone can verify the trade.

Estimate your savings

You save ~0.08 SOL/month in network + priority fees

* Varies with priority fees and network conditions. For illustration only.

How It Works

A cleaner path from wallet to verified execution.

Neptune keeps the flow simple: connect, pick or launch a market, post collateral, trade, verify, and withdraw. Same protocol flow, clearer surface.

6
Core steps
1
Verification path
Step 01On-chain

Connect Wallet

Phantom, Solflare, or any Solana wallet. No signup, no KYC. One click and you are in.

Step 02On-chain

Launch or Pick a Market

Deploy a new perpetual market in 60 seconds or open an existing one. Fully permissionless.

Step 03On-chain

Deposit Collateral

Transfer collateral into the market vault. Fully on-chain, non-custodial, verifiable.

Step 04On-chain

Trade Perps

Risk-increasing trades require a fresh crank. Neptune enforces freshness and lets you crank in one click.

Step 05On-chain

Verify On-Chain

Receipts include CPI call chains + upgrade authority — not just an explorer link.

Step 06On-chain

Withdraw Anytime

Close your position, pull collateral back. Your keys, your funds. Always.

Built different.

Launch markets permissionlessly in under a minute.

Neptune lets anyone deploy Percolator-style perp markets with real collateral, on-chain settlement, and full program truth — no KYC, no approvals. Free on devnet.
