Strategy Types Explained

Free Gas (Type 0)

With this strategy, you fully cover the gas costs for your users. This is ideal for:

• Onboarding new users who don’t own crypto
• Promotional campaigns
• Applications where you want to remove all friction
• GameFi applications where you want to hide blockchain complexity

ERC20 Prepay (Type 1)

Users pay for gas using ERC20 tokens before the transaction is executed:

• The full estimated amount is collected upfront
• Any excess is refunded after execution
• More secure for the developer as payment is guaranteed
• Better suited for high-value operations

ERC20 Postpay (Type 2)

Users pay for gas using ERC20 tokens after the transaction is executed:

• Only the exact gas cost is collected
• Requires token approval before execution
• Slightly better UX as users only pay what’s needed
• Has a risk of payment failure after execution
