Short answer
jeton SOL is Solana's native asset and is commonly used for network fees and portefeuille-level payments. jetons SPL are tokens built on Solana's token standard; games may use them for assets, balances, rewards, or special utility depending on design.
For players, the practical question is simple: what am I paying, what am I receiving, and which balance will change? A good game makes that visible before any portefeuille approval.
The design tension
jeton SOL is familiar because it is the base asset of the network, but using it everywhere can make a game feel financially intense. jetons SPL can represent more specific game value, but they add vocabulary and may require token accounts.
The design challenge is clarity. Players should not have to guess whether a cost is a network fee, an entry price, a token transfer, or a reward distribution. The same portefeuille can show several asset types, and the game has to label them responsibly.
Player benefit
When jeton SOL and jetons SPL are explained well, players make calmer decisions. They can separate unavoidable network costs from optional game costs, and they can understand why a token account may appear in a flow.
This also reduces support friction. Many portefeuille questions come from unclear asset language rather than from the chain itself.
Clear asset language also helps players manage risk. They can keep enough jeton SOL for fees, recognize when a game is asking for more than a fee, and avoid approving a transfer they did not intend.
Merveille example
Merveille should keep jeton SOL language especially careful around pools, payments, and settlement. If an action involves jeton SOL, the player should understand whether it is a fee, a cost, a prize context, or a reward-related event.
If SPL-style assets or token accounts appear later, they should be introduced as specific game instruments, not vague crypto decoration.
What to watch
Watch for prompts that mix terms: fee, payment, reward, token, claim, and transfer should not be used interchangeably. Each word should point to a real action.
If the interface cannot explain which asset is moving and why, the player should slow down before approving.
