Testnet Scheduled Maintenance Announcement Please be advised that the testnet will undergo a scheduled protocol and network upgrade today. • Maintenance Window: 17:00 – 21:00 UTC+8 (4 hours total) • Service Impact: All testnet services—including testnet RPC nodes, block explorers, cross-chain bridges, and the testnet faucet—will experience full downtime during this window. • User Action: Please pause active deployments, automated transactions, and AI agent testing prior to 17:00. Unsubmitted or pending transactions may fail to execute while nodes are brought offline for updating. All services will automatically resume once full network synchronization is completed following the upgrade.

Testnet FLOP tokens, which will convert at a to be determined ratio into Mainnet FLOP tokens, will be tradable using our HTLC protocol for real money. Stay tuned for more details. There is even more incentive to particpate as a miner, validator, or agent during @flop_labs Testnet.

Testnet has processed over 10 billion transactions, and its storage footprint grows with them. Periodic resets keep it bounded. Full policy in AIP-147, introduced by @AptosLabs' @sherryxiao:

Testnet is Completed, see you on Mainnet ✔️ Over 66,344 visitors showed up, doing: 159,366 auction bids, 96,119 decision market trades and 9,533 position settlement claims. On Saturday, Umia accounted for 28.5% of ALL transactions on 🟦 @base Sepolia Testnet was a great load test for our infrastructure, helping us prepare for our release. Thanks to everyone who volunteered to test our network and share feedback on our UI, even without any incentives. Now, it's time to get everything ready for mainnet and $UMIA

Glamsterdam testnet delayed. @chain_security found the new gas rules could change how existing contracts handle failed calls, so devs paused Hoodi to review it first. no new date yet

Sepolia testnet validators: update your nodes. Today at ~4pm, we’ll see Glamsterdam (Gloas + Amsterdam) go live on Sepolia. This marks a major milestone for Glamsterdam and for Ethereum more broadly. Glamsterdam’s main focus has been scaling, but at the same time the fork also reduces trust requirements, improves sync, and harmonizes resource pricing to improve DoS resistance as the chain scales. It will likely be the largest Ethereum fork since the Merge, and it has been ambitious from the beginning. ePBS and BALs were selected as headliners early on, and the fork’s theme - scaling - evolved quite naturally from there. When core devs later decided to reprice the EVM as well, the fork’s surface area increased quite a lot and Glamsterdam became a much broader upgrade than initially expected. That also meant more work across specs, clients, tooling, and testing. Almost a year of benchmarking, implementation work, refining specs, testing and devnets followed, and over time Glamsterdam has really started to harden. It has also been the first fork where AI played a major role across basically the whole pipeline: research, benchmarking, testing, client implementations, and security audits, which is interesting to witness. One can clearly feel the accelerated pace at the frontlines: while Sepolia is forking to Glamsterdam, core devs are already busy shipping the first Hegota devnets. Ethereum is not yet where it needs to be, but we’re getting there. Fork after fork, the chain becomes more scalable, more robust, and more capable. And with post-quantum security likely becoming one of the main focus areas over the next few years, there is still a lot ahead.
