# Built-in wallet

Your goodcryptoX wallet gives you secure access to decentralized trading through a unified, powerful interface — across all supported blockchains.

On EVM chains, your goodcryptoX wallet is a fully non-custodial [Smart Contract Wallet](/wallets/built-in-wallet/smart-contract-wallets.md), with your private key protected by [Multi-Party Computation](broken://pages/6BOqlCAilnSbGFvhwiBc) (MPC). The key is never exposed — not to us, not to your device, not to anyone.

To enable [conditional orders](/dex-trading-spot/manual-orders.md) and [automated trading](/dex-trading-spot/bots.md), we use [session keys](/wallets/built-in-wallet/smart-contract-wallets/session-keys.md) — special keys enabled by Smart Contract Wallets, with onchain-verifiable permissions. Session keys allow goodcryptoX to only execute swaps on your behalf, and cannot be used for any other blockchain operations.

On Solana, your wallet also benefits from MPC protection, ensuring your private key is never reconstructed on your device. While Solana doesn’t yet support Smart Contract Wallets or session keys, we apply the same principles to provide a secure and consistent experience.

You’ll soon be able to [bring your own wallet](/dex-trading-spot/manual-orders.md) — both on EVM chains (e.g. MetaMask) and Solana (e.g. Phantom). On EVMs, we’ll leverage EIP-7702 to issue session keys to your existing wallet, enabling full goodcryptoX functionality without compromising custody. On Solana, external wallets will be importable directly into the app.

Whether you’re using our built-in wallet or bringing your own, goodcryptoX gives you full control, full security, and full trading power — across chains and protocols.
