Transaction Fees

Tempo has no native token. Instead, transaction fees—including both gas fees and priority fees—can be paid directly in stablecoins. When you send a transaction, you can choose which supported stablecoin to use for fees.

For a stablecoin to be accepted, it must be USD-denominated, issued as a native TIP-20 contract, and have sufficient liquidity on the native Fee AMM.

Tempo uses a bounded dynamic base fee. It can fall when block gas usage is below target and rise back toward the cap when the network is busy. For a 50,000 gas transfer, the base-fee cap is about $0.0006, with a quiet-period floor around $0.00003. All fees accrue to the validator who proposes the block.

For pool mechanics, swaps, liquidity accounting, and fee-token conversion rules, see the Fee AMM specification.
