BNB ChainFree Trial · BNB Chain·30 days · 2,000 gasless TX · Q402 covers gas

Free trial. No gas. No card.

2,000 gasless transactions on BNB Chain (USDC + USDT) for the next 30 days. Q402 covers the gas— no card, no gas tank. Sign up with Google, email, or wallet to get your live and sandbox API keys in 30 seconds.

Step 1 — sign up

Get your API key

One click — pick Google, email, or wallet. 2,000 sponsored TX + a BNB-only API key are waiting on the other side.

Google, email, and wallet all activate the same 2,000-TX trial immediately — live key (real on-chain settlements, gasless for the payer) and sandbox key issued in one shot. One identity, one trial (ever).

What you get
  • 01
    2,000 gasless transactions
    Stablecoin transfers (USDC / USDT) on BNB Chain. The payer signs once off-chain, Q402's relayer pays gas, the recipient gets the full amount.
  • 02
    30-day window
    Trial credits live for 30 days from activation. Convert to a paid plan inside that window to keep credits flowing without interruption.
  • 03
    Q402 covers all gas
    You never deposit BNB into a gas tank. Trial relays draw from the platform's gas budget — sender pays $0, recipient gets 100%.
  • 04
    Both live + sandbox API keys
    Live key signs real on-chain TX. Sandbox key (q402_test_*) returns mock results — use it for integration tests without burning real credits.

After the trial

Trial credits don't roll over — top up at Pricing to keep gasless payments live. Live key auto-expires 30 days after activation if not converted; sandbox key stays active forever.
