TL;DR:
Aptos enabled an optional encrypted mempool directly on its mainnet on October 12, 2026.
The technical rollout coincided with the conclusion of the four-year token vesting schedule for early network participants.
Monthly APT circulating supply unlocks drop by 60%, curbing new token emissions allocated to early-stage investors.
On Monday, October 12, the Layer 1 ecosystem completed the deployment of its Aptos encrypted mempool on mainnet, introducing a native privacy layer designed to shield pending transactions from actors executing maximal extractable value ( MEV ) exploits.
The technical upgrade went live on the exact date marking the completion of the four-year vesting schedule for initial contributors and institutional seed investors. This milestone significantly lowers the recurrent issuance rate of the native asset APT across the open market.
The architecture allows users to submit transactions in ciphertext format before broadcasting them to network validators. Consequently, order specifics remain confidential while queued in the mempool, preventing searcher bots from detecting slippage tolerances to execute sandwich attacks or perform latency arbitrage.
Transaction payloads are decrypted and revealed only after block ordering is finalized. Technical documentation from Aptos Labs indicates that individual validators cannot unilaterally decrypt transactions; instead, key generation requires a stake-weighted threshold consensus mechanism for each operational epoch.
Aptos Labs researchers documented in their architectural benchmark that this batching pipeline introduces approximately 27 milliseconds of consensus latency. Findings from the technical report show that this latency overhead represents a 14% increase compared to baseline unencrypted network execution.
To balance network throughput, transactions routing through the encrypted mempool carry a base fee of 200 Octas per gas unit—double the network’s standard minimum gas price.
60% Unlock Reduction and Market Dynamics
From a tokenomics standpoint, the expiration of the original vesting schedule triggers a structural shift in APT circulating supply dynamics . With lockup agreements expiring for insiders and venture funds four years following network genesis, scheduled emissions earmarked for this cohort cease completely.
The conclusion of this schedule reduces periodic token unlocks by approximately 60%. Remaining unlock tranches will be restricted primarily to ecosystem grants, community incentives, and staking rewards.
The APT token was trading at $0.84 on Bitget with a 24-hour trading volume of $983,366 and a market capitalization of $745.5 million as of October 13, 2026. Circulating supply stood at 882.88 million tokens.
Market analysts note that a reduced influx of secondary market liquidity may relieve the recurring sell pressure observed around previous monthly unlock dates. In parallel, industry observers highlight that native mempool privacy could bolster institutional decentralized finance ( DeFi ) activity on Aptos by mitigating slippage losses from predatory order execution.
The protocol’s governance roadmap includes a comprehensive technical review 30 days post-launch to assess network adoption and throughput across encrypted transaction flows.
