Trading API

Fast Solana execution without trapping the user inside the platform

Corto.Fun gives teams fast server-side trading without locking user funds inside the platform. Generate the wallet once, keep the private key with the user, fund the wallet directly, and use the paired API key for trading.

Why teams choose this model: if Corto.Fun goes offline, user funds do not get trapped in a platform-only balance. The private and API keys are shown once during generation, stay with the user, and keep the exit path outside Corto.Fun. See why this is safer.

Start here: create the key bundle on Wallet Tools, import the private key into your wallet, fund it, then use the paired API key here. If you want signing to stay on the wallet side, use Local Build.

Build and send trade

API Key Mint address Action Amount Amount mode Buy: amount is typically in SOL. Slippage % (1-99) Pool Priority Fee SOL (opt.) Jito Tip SOL (opt.) Ack mode Max route ms (opt.) Project ID (opt.) User memo (opt.) Partner address (opt.) Partner fee ratio (opt.) Partner fee fixed SOL (opt.) Jito minimum tip is 0.0002 SOL. If only priorityFee is passed and it is >= 0.00023 SOL, service may auto-split 90/10 (tip/priority). Project ID is optional and used only for developer analytics attribution when one partner wallet serves multiple products, bots, or campaigns. Memo is optional. Your memo has priority. If branded memo is enabled and both fit, the service appends via corto.fun. If not, your memo stays unchanged.

Why this is easier to trust

Your funds are not trapped inside a platform subaccount. If Corto.Fun is unavailable, the wallet still remains under your control through the private key you saved.
