AIP-146 is open to anyone who can control enough stake $APT Transactions can be pushed at up to 100 times the network’s normal gas limit, but overall this is good news for the token. DeFi Substantive reasons to bet $APT This can be exceeded by yield alone. This is not a distant roadmap item either. The proposal was accepted and passed with near-unanimous support through an on-chain governance vote, and Aptos Labs (@AptosLabs) started promoting the upgrade this week.
What is AIP-146?
Currently, all Aptos transactions run under the same execution and I/O gas limits. While this works for swaps and transfers, it is limited for heavy operations such as DEX liquidations, risk engine updates, large state transitions, and complex financial logic that requires more compute in a single transaction. Teams that reach their limits split their work or move some of it off-chain.
AIP-146titled “Staking-Based Transaction Limits” and authored by George Mitenkov (@George MitenkovAptos Labs’ ) now has an opt-in fix. Transactions can request higher limits, expressed in basis points, from just over 1x to a hard cap of 100x. To qualify, ratepayers must demonstrate control over a committed amount $APT stake. This first version only increases execution limits and I/O limits; storage charges remain unchanged.
This benefit has a built-in cost. Stakebacked high-limit trades require you to pay at least 10 times the minimum gas unit price, and we intentionally discourage spam and frivolous usage. Upper bound transactions also receive no special treatment in mempool.
How do staking tiers work?
Three roots count as proof of staking. Owning a stake pool, being a delegated voter in a stake pool, or holding stake in a representative pool. Committed stake means active balances and pending and inactive balances checked against live on-chain status.
The Genesis configuration sets up three tiers with separate thresholds for execution and I/O.
- 2x multiplier: 1 million $APT (Execution) or 5 million $APT (I/O)
- 4x multiplier: 5 million $APT (Execution) or 10 million $APT (I/O)
- 8x multiplier: 10 million $APT (Execution) or 20 million $APT (I/O)
I/O thresholds are high because reading and writing state is more expensive for the network than raw computing. Requests are rounded up. Requesting 3x will require a 4x tier stake. Governance can add, remove, or reshape hierarchies at any time without changing code, so the 100x limit isn’t something you’ll be able to take advantage of from day one, giving you more headroom for the future.
AIP-146 Do you want to lock up more? $APT?
Here’s what’s interesting about this proposal $APT holder. Access to higher limits is valuable for protocols running critical on-chain workloads, and the only way to do that is through committed stake. This will encourage DEXs, PERPS platforms, market makers, and institutions to stake or arrange for staking in addition to earning regular rewards and governance powers.
apartment I’ve spent the last few months rebuilding it. tokenomics: Hard supply limit 2.1 billion $APT For the current supply of approximately 1.2 billion, transaction fees have been burnt and the base staking reward rate has been reduced to approximately 2.6% through governance. As yield alone is less attractive than before, tying network capabilities to equity gives large holders new incentives to lock in. $APT Rather than leaving it liquid. Approximately 770 million $APT The mechanism is already built on a high baseline, as around 64% of the supply is already staked.
The deployment proceeded quickly. This proposal was created in April 2026, accepted in the AIP repository in early July, and made effective through on-chain Proposal 200, Enabling Transaction Limits. That vote attracted 369.9 million people. $APT Upvoted, only 1,449 $APT It was voted against with a 30.7% turnout and has been running on mainnet ever since. Actual implementation will still be delayed. SDK and CLI support will be tracked separately and wallets will need to add new transaction formats before capped transactions become routine.
is that good news $APT?
In most cases, yes. This upgrade removes a technical cap for exactly that type of application. @aptos is embarking on an on-chain market push, and is doing so in a way that translates network capacity into staking demand. Large stakers, who carry the real economic weight, also have the right to participate in the game, and this is the logic that ties privilege to stake.
Admission tickets start from 1 million yen $APTSo this is a feature for protocols, funds, and whales, not for retail. By design, network privileges are concentrated in the hands of the greatest holders. This mechanism is shipped as an experiment, and builders are instructed not to rely on guaranteed access, as hierarchy and access are subject to change by governance. Still, the direction is clear. Aptos just gave the heaviest users a real reason to lock up. $APTand the staking rate indicates whether they will take it or not.
