Web3 continues to grow, but getting started still feels harder than it should be. New users are often required to acquire a blockchain’s native token just to interact with the network, even if they do not plan to use it again. The Incentiv Unified Token, now live on the Incentiv Testnet, removes that friction by allowing users to pay transaction fees using any supported token in their wallet.

This simplifies transactions and eliminates the need to manage multiple tokens for different actions. The protocol automatically handles conversions through Incentiv’s integrated DEX, all in the background. Unlike platforms that depend on external relayers, Incentiv processes everything natively within the network, offering a seamless, flexible, and accessible experience from the start.

How to Use the Unified Token

Using Unified Token on Incentiv makes swapping and sending tokens more flexible than ever. It leverages both the integrated DEX and Account Abstraction to handle payment logic automatically. Here’s how you can use it:

1. Log in to your Incentiv Portal and select either the “Swap” or “Send” action. This will bring up the interface where you can view your available balances and manage your transaction.
2. For swaps, select the token you want to exchange and the one you want to receive. For sending, enter the recipient’s wallet address and choose the token you want to send.
3. Enter the token amount. The system will automatically calculate the expected output for swaps and show the estimated gas fee for both actions.
4. Use the dropdown menu to select a token for gas fees. Only tokens with enough balance to cover the fee will appear. Currently, TCENT is selected by default if available, but you can choose from other supported testnet tokens like SMPL, BULL, or FLIP.
5. Review all transaction details carefully, including the amount, gas token, and recipient if applicable. Once ready, confirm the transaction using your passkey or approve via MetaMask or WalletConnect.

Under the Hood: How Unified Token Transactions Work

Unified Token transactions leverage Account Abstraction, smart wallets, and a custom-designed DEX Paymaster to abstract gas fees and deliver seamless on-chain experiences. The entire flow is engineered to ensure users can cover transaction costs using any supported token without external relayers or off-chain services.

When a transaction is initiated, the smart wallet constructs a bundled transaction, which includes multiple actions combined into a single atomic operation. The transaction bundle follows a required sequence to ensure fee coverage and guarantee Paymaster reimbursement. The critical steps include:

1. Token Approval — The first action in the bundle is an approval operation, authorizing the integrated DEX router to spend the user’s chosen token.
2. Token Swap to TCENT — The second action swaps the approved token into TCENT through the integrated DEX. The swapped TCENT is sent directly to the Paymaster’s address.

At this stage, before any user-specific actions are executed, the DEX Paymaster performs validation. It inspects the bundled transaction and verifies:

• The presence of the approval and swap actions as the first two operations.
• The swap route and output ensure that TCENT will be received by the Paymaster in sufficient quantity to cover the gas fees.

If these conditions are met, the Paymaster pre-approves gas sponsorship for the remainder of the bundled transaction. This means the Paymaster will cover the gas fees upfront, confident it will be reimbursed as TCENT from the swap once execution completes. However, if the paymaster fails the verification, the bundler will reject all the operations inside the UserOperation.

3. Execution of User Transactions — Following validation and approval, the remaining user-defined actions such as token transfers, swaps, liquidity operations, or other dApp interactions are executed in sequence, utilizing the gas sponsored by the Paymaster.

4. Final Settlement — At completion, the Paymaster is reimbursed in TCENT from the earlier swap, and the transaction is finalized on-chain in a fully self-contained flow.
