Pred User API
Safe approval endpoints for enabling trading on your proxy wallet.## Safe approval signature — raw secp256k1- Sign the `transactionHash` from prepare response **directly** (raw secp256k1)- **No EIP-191 prefix** / no `personal_sign`- Format: `0x` (132 hex chars) with low-s normalization- `v` normalized to 27 or 28**MANDATORY: After completing Safe approval (prepare, sign, execute), you MUST call `POST /api/v1/auth/login-with-signature` again to get a fresh JWT with `is_enabled_trading=true`. Without this re-login, order placement/cancellation will fail with "trading not enabled". A token refresh alone is NOT sufficient.**
