💸 8M Refunds Cleared with Revert Book.

Protocol V2 Rollout: important performance & security tune-up

A major upgrade this month is the individual attestation of reverts, a key feature in the t3rn Protocol V2 rollout. Previously, reverts depended on timeouts, creating race conditions where late executions led to discrepancies between rewards claimed by executors and users.

The introduction of a separate revert book—deployed to t3rn's testnet on Arbitrum Orbit as a set of smart contracts—addresses this issue by ensuring that a single settlement cannot exist simultaneously in both committed and reverted states.

This setup handles revert approvals through quorum-based attestation while preventing reverts on already-committed orders. Not only does this resolve inconsistencies, but it also strengthens the protocol's reliability in high-volume scenarios.

Clearing 8 Million Pending Refunds

With the revert book now live, we’ve cleared 8 million pending refunds in the testnet environment over the past few weeks. This milestone showcases the protocol's ability to scale effectively, ensuring all pending transactions from the start of the testnet are fully resolved.

Optimizing Batch Execution

As part of our ongoing focus on high-volume optimization, the batching mechanism has been a cornerstone. The executors on testnet rely mostly on the batch version of the execute function to each individual Layer 2 EVM, it allows us to group transactions by target and asset. Its flow can be simplified to 2 steps:

• consolidate orders sharing the same target and asset into a single batch.

• validate for double execute and emit necessary events individually but bulk the transfers collectively for maximum efficiency.

For instance, in a batch of 100 orders targeting the same asset, execution consumes ~800k gas, compared to 8.5M gas if processed individually. On Arbitrum Sepolia, this brings down the per-settlement cost from ~$0.02 to as low as $0.002.

New batching strategy ensures similar efficiency gains for the protocol by grouping transactions intelligently.

Next Steps

Our upcoming efforts will focus on segment-based improvements to the claims book and refining the executor mechanism for even greater scalability. Stay tuned for more updates in next month's Multi Chain Matters!
