Quick Answer
Compare each platform’s current custody, key-export and recovery documentation directly. The published wallet documentation describes user-controlled, exportable private keys. Agent execution is separately documented as using server-side managed wallets; review that model before enabling automation. Secure your sign-in account and any exported backup. Self-custody does not eliminate interface, account, smart-contract or market risk.
GDEX supports nine highlighted chains: Solana, Ethereum, Base, BNB, Arbitrum, Optimism, Sui, Sonic, Berachain. Verify each alternative’s current chain and feature coverage directly; no ranking is established here.

None of these three are centralized exchanges and none are classic decentralized exchanges either — they're terminals that route your trades through underlying DEX liquidity while you hold your own keys. The differences that actually matter are chain coverage, fees, and whether you can onboard without a seed phrase or KYC.

When to pick GDEX Pro
The FAQ describes mirroring up to 6 AI agent wallets through copy trading. Risk presets belong to the separate Agent Risk Terminal, which documents up to five running agents. These are different features with different controls; review the current documentation before allocating funds.
- Multi-chain traders who don't want separate terminals per chain
- New users who want to buy in with Apple Pay and skip KYC and seed phrases
- Traders who want HyperLiquid perps alongside spot swaps
- Anyone who wants rule-based AI agents rather than manual copy-trading
When to pick BullX or Photon
Compare each platform’s current custody, key-export and recovery documentation directly. The published wallet documentation describes user-controlled, exportable private keys. Agent execution is separately documented as using server-side managed wallets; review that model before enabling automation. Secure your sign-in account and any exported backup. Self-custody does not eliminate interface, account, smart-contract or market risk.
Neither offers a built-in Apple Pay on-ramp or native perpetuals trading, so you'll need to bring funds in separately and use another venue for leveraged positions.
Fees and risk, honestly
All three are self-custody tools: you hold your keys, and no support team can reverse a transaction or recover funds sent to the wrong address. GDEX Pro's swap fee is roughly 1%, and its Apple Pay on-ramp adds a separate ~2-3% fee on top, with a $50 minimum purchase — factor both in before assuming a single 'trading fee' figure.

Because there's no KYC on any of these platforms, you are responsible for your own transaction records and any applicable local tax reporting.
Custody and sign-in, side by side
Compare each platform’s current custody, key-export and recovery documentation directly. The published wallet documentation describes user-controlled, exportable private keys. Agent execution is separately documented as using server-side managed wallets; review that model before enabling automation. Secure your sign-in account and any exported backup. Self-custody does not eliminate interface, account, smart-contract or market risk.
Neither approach is 'safer' in an absolute sense — they're different onboarding trade-offs. Web3Auth sign-in lowers the barrier for new users at the cost of trusting the threshold-key infrastructure; bringing your own wallet keeps you on tools you may already trust but puts seed phrase management fully on you.
