Aptos activated a feature that allows its largest stakers to process transactions at up to 100 times the network's normal limits. The feature, known as AIP-146 and authored by George Mitenkov of Aptos Labs, gives large APT holders a new functional reason to stake beyond earning yield. Aptos is a layer-1 blockchain network designed for high transaction throughput and low fees, supporting decentralized finance trading and real-world asset tokenization.
Aptos Addresses Transaction Processing Ceiling with AIP-146
Every transaction on Aptos has run under the same processing limits, regardless of task complexity. This works for simple transfers and swaps but creates a ceiling for heavier workloads like liquidations on decentralized exchanges, large-scale data migrations, or emergency actions requiring more computing power in a single transaction. Teams hitting that ceiling have had to break work into smaller pieces or move parts off the blockchain entirely.
AIP-146 gives transactions an opt-in way around the standard limit. A transaction can request higher processing power, scaling from just above the standard rate up to a hard cap of 100 times normal. To qualify, the party paying for the transaction must prove they control a substantial amount of staked APT.
Staking Thresholds Determine Access to Higher Limits
Under the tiers proposed with the AIP, unlocking a 2x multiplier on execution requires roughly 1 million APT in committed stake; 4x requires about 5 million APT; and 8x requires around 10 million APT. The limits governing data reads and writes carry even higher thresholds, starting at about 5 million APT for the first tier. The exact tiers are set by on-chain governance and can be adjusted over time.
At those levels, this is not a retail feature. As the proposal itself acknowledges, the large stakers who qualify are overwhelmingly exchanges, custodians and validators — players with millions of dollars of APT already committed to the network. Smaller participants cannot reach the higher multipliers, which is by design: the whole point is to tie elevated power to a large, verifiable economic stake.
A fee payer can prove that stake in three ways: by owning a stake pool directly, by being the designated voter for one, or by being a delegator in a delegation pool.
AIP-146 Targets DeFi Liquidations and Emergency Actions
Liquidations are a clear example of where this matters. When a liquidation transaction fails because it hits the standard processing limit, bad debt on the platform continues to grow and users end up absorbing larger losses. By allowing qualifying transactions to request higher limits, protocols get more reliable execution for exactly the kind of heavy transactions that keep onchain markets functioning during periods of stress.
For large holders of APT, this creates a genuine functional reason to stake beyond collecting yield, tying the token's usefulness more directly to real network activity.
Aptos Reserves Right to Modify or Remove Feature
Aptos is clear that the feature is experimental. The proposal states that the mechanism may be "modified, restricted, or removed at any time" if it introduces risks to performance, security or fairness, and it explicitly warns that developers "should not build systems that critically depend on guaranteed access to higher transaction limits." In other words, the capability is real and live, but Aptos has reserved the right to change the rules, the thresholds, or the feature itself as it watches how the network uses it.
FAQ
What did Aptos activate for large stakers?
Aptos activated AIP-146, a feature allowing large stakers to process transactions at up to 100 times the network's normal limits. The feature is opt-in and requires proof of substantial staked APT to qualify.
How much APT do stakers need to access higher transaction limits?
Unlocking a 2x multiplier requires roughly 1 million APT in committed stake, 4x requires about 5 million APT, and 8x requires around 10 million APT. Data read and write limits start at about 5 million APT for the first tier.
Why does Aptos describe AIP-146 as experimental?
Aptos states the mechanism may be "modified, restricted, or removed at any time" if it introduces risks to performance, security or fairness. The proposal warns developers not to build systems that critically depend on guaranteed access to higher transaction limits.
