Ethereum’s Fusaka upgrade is nearing its crucial third testnet iteration as core developers finalize the “go/no-go” decision criteria. With only a handful of pull requests left to merge and performance benchmarks underway, the community is poised to decide whether Devnet 3 can launch on schedule or needs more testing time.

Three PRs Stand Between Devnet 2 & Devnet 3

Core Devs confirmed that only three pull requests remain unmerged before Devnet 3 can spin up. The transaction gas‐limit cap of 45 million is already merged, leaving two critical PRs. All client teams have been urged to integrate these changes ahead of Thursday’s core developer sync to lock in a timeline for launch readiness.

Benchmarking

Core Devs have outlined a two-month window for clients to implement high‐throughput benchmarks (e.g., 100 million blobs per block) and build necessary code-size indices. Should any client miss this deadline, the network may disable the index feature or retract the EIP entirely to prevent last-minute instability, ensuring only well-tested changes ship in Devnet 3.

ACDE to Host Final Review

To uphold rigorous testing standards, all collected metrics & client feedback will be presented at the next All Core Developers Execution (ACDE) meeting. Developers will evaluate real-world data on code-size indexing performance, sync stability & gas-limit compliance before issuing the final “go” for Devnet 3 or recommending a postponement if any EIP remains insufficiently vetted.

Conclusion

Assuming all PRs merge and benchmarks validate network resilience, Fusaka Devnet 3 could launch as early as late July. Any delays in EIP merges or benchmark rollouts may push the timeline into August, compressing the testing window.
