T7 Network Upgrade

T7 gives partners a clearer fee model for high-volume payment and exchange flows. It adds storage credits for reusable DEX order and TIP-20 channel state, makes the base fee move down when network usage is below the target threshold, and deprecates new TIP-20 rewards.

Timeline

Node operators should upgrade to v1.10.1 before the activation timestamp on each network.

Overview

T7 focuses on three partner needs:

• Lower fees for reusable protocol state. Storage credits reduce fees when previously freed protocol storage can be reused, including DEX order storage and TIP-20 channel storage.
• A more responsive base fee. Dynamic base fee behavior lowers the base fee when gas usage is below the target threshold.
• A simpler TIP-20 rewards model. Deprecating new TIP-20 rewards simplifies reward-related accounting and user-facing balances.

These changes are designed to make costs easier to reason about for partners building high-throughput payment, liquidity, and exchange experiences. Storage credits and dynamic base fee behavior affect fee calculations, while existing TIP-20 transfer behavior and claims for already-accrued rewards continue to work.

Features

Storage credits for reusable protocol state

Storage credits lower fees for protocol surfaces where deleted storage can later be reused. This helps reduce the cost of flows where the network can account for reusable state separately from net-new long-lived state.

Dynamic base fee

Dynamic base fee behavior lets the base fee move down when gas usage is below the target threshold. This gives wallets, apps, and infrastructure a fee model that can respond to lower network usage instead of assuming a fixed base fee.

Deprecate TIP-20 rewards

T7 deprecates new TIP-20 reward opt-ins and reward distributions so partners do not need to model new reward accrual after the upgrade. Already-accrued rewards remain claimable, so historical rewards data should remain separate from post-T7 payment and balance reporting.

Compatible releases

The following release supports the T7 feature set:

Release notes and binaries are available in the v1.10.1 release.

What operators and integrators should know

T7 changes fee and reward behavior. Node operators, integrators, indexers, wallets, and partner infrastructure should review the notes below before testnet and mainnet rollout.

For storage credits

Partners using DEX or TIP-20 channel flows should review fee assumptions once the T7-compatible release is available.

• Storage credits are included for the core primitive, DEX order storage, and TIP-20 channel storage.
• Wallets and apps that estimate fees should validate their fee displays against T7 behavior on testnet.
• Indexers and analytics systems should keep pre-T7 fee assumptions separate from post-T7 fee data.

For TIP-20 rewards deprecation

Apps that show TIP-20 reward information should stop presenting new rewards as accruing from post-T7 reward distributions.

• Wallets and dashboards should separate already-accrued rewards from post-T7 balances.
• Accounting and reporting systems should check whether any reward-specific assumptions remain.
• Partner support teams should be ready to explain that TIP-20 transfers and claims for already-accrued rewards continue to work, while new reward opt-ins and distributions are deprecated.
