How to pick among the 5 chains

Chain	On-chain fee	Confirmation	Who it fits
TRC20	~$1	1-3 min	Daily retail top ups — cheapest, default pick
ERC20	$3-15	3-10 min	Larger amounts, security-sensitive flows
BSC	~$0.30	1-3 min	Binance ecosystem users
Arbitrum	~$0.50	1-3 min	L2 users, technical crowd
Solana	~$0.01	30s	When you want the fastest credit

Do NOT mix chains! USDT on TRC20 cannot be sent to an ERC20 address, and vice versa. Double-check before you send.

3. Create an API Key

Create as many as you want — each with its own limits

1
Go to /keys and click "Create Key"
Name (required), optional RPM cap, optional cumulative spend cap, optional expiry.
2
Copy the full key immediately and save it
Key format: sk-eastx-XXXXXXXX.... Shown only once at creation — once you close the dialog it's gone for good.
3
Wire it into your SDK or env var
We recommend an env var like EASTX_KEY — don't hard-code, don't commit.

Key leaked? What now? Go to /keys and disable it, then create a new one. Spend incurred during the leak counts as real usage and is non-refundable.
