The altcoin market delivered a series of sharp moves in late September 2026, with three stories dominating attention. Cardano (ADA) climbed 26% in a week after the blockchain integrated an AI payment SDK that lets software agents transact directly in ADA, a use case that places Cardano inside a conversation most Layer 1 networks are still trying to enter. NEAR Protocol (NEAR) moved even more sharply, surging 80% in seven days on the launch of confidential perpetuals trading, with the token at $4.18 and $5 in analysts' sights.

Alongside those moves, BlockDAG announced a change to its presale economics: the USDT Buyback Price has been raised from $0.02 to $0.03 — .5 times higher — for a 7-day window only. During the window, direct BDAG is priced at $0.00000017, and both Legacy and New BDAG purchases build a holder's eligible Buyback Allocation, with the dashboard displaying a unified USDT balance.

Cardano (ADA): 26% Weekly Gain as AI Payment Integration Signals New Use Case

Cardano produced one of the cleaner stories of the past week. ADA jumped approximately 26% in seven days, climbing from below $0.19 to $0.2513 as of September 23, 2026, per CryptoTimes data. Daily trading volume reached around $846 million during the move, and market capitalization crossed $9.38 billion.

The catalyst that separates the rally from a simple market-rebound move is the x402 SDK integration. The update enables AI agents and applications to process payments directly in ADA without requiring accounts or API keys. That detail is where the AI-payments theme turns practical: autonomous software can settle value in a native token on its own, and developers wiring agents into payment flows skip the account-and-API-key setup such connections would otherwise need — the positioning the coverage places inside a conversation most Layer 1 networks are still trying to enter.

September 23 also marks Cardano's ninth anniversary, with the genesis block launched on this date in 2017.

Analyst Giannis Andreou flagged $0.24–$0.25 as the key resistance level, with $0.31 as the next major target if ADA establishes a daily close above the zone and holds it on a retest. That close is the technical requirement the Cardano price needs to extend the move.

NEAR Protocol (NEAR): 80% in Seven Days After Confidential Perpetuals Launch

NEAR delivered the standout altcoin move of the week, and the catalyst behind it is concrete. NEAR climbed approximately 80% in seven days, rising from around $2.20 to $4.18 as of September 22–23, 2026, per Coinpedia analysis.

The driver was the launch of confidential perpetual futures trading powered by Hyperliquid, a product that allows users to open positions without their trades being publicly linked to their wallet address. The feature speaks to a baseline property of public blockchains: activity on transparent ledgers is openly inspectable, which is precisely the exposure confidential trading is built to remove. That product pushed NEAR above a multi-year descending resistance structure that had capped the NEAR Protocol price through several market cycles.

Analysts are targeting $4.80–$5.00 if NEAR holds a weekly close above the $4.20–$4.40 supply zone, with $3.30–$3.50 as the key support to defend on any pullback.

The breakout is backed by a product with clear demand — privacy-preserving trading — rather than macro sentiment alone, a distinction the analysis says gives the move more structural weight than a standard altcoin rally.

BlockDAG (BDAG): USDT Buyback Price Raised From $0.02 to $0.03 for 7-Day Window

While many presale projects speak in general terms about holder value, BlockDAG has now quantified it and raised the figure by 1.5 times. The project has finalized a new structure that allows the USDT Buyback to move forward under updated requirements. The previous buyback price was $0.02; for the next 7 days, it is $0.03 — not a rounding difference, but a meaningful increase in what every eligible BDAG purchase is worth in the buyback calculation, according to the announcement.

The mechanics, as described by the project:

• Direct BDAG is available at $0.00000017.
• Eligible purchases of Legacy BDAG and New BDAG made during the 7-day window build a holder's Buyback Allocation.
• That allocation goes through compression to a final eligible amount, which is then valued at $0.03.
• There is one unified balance, with no split calculations and no guesswork about which tranche counts for what.
• The previous eligible Buyback amount has already been restored and is visible in every verified holder's dashboard, with Legacy BDAG and New BDAG sitting together under one unified US Buyback Balance and the dashboard calculating everything automatically.

The distinction matters for how the number should be read: $0.03 is not the direct-purchase price but the valuation applied to a final eligible amount after compression, so the uplift flows through the buyback calculation itself.

The project said the change did not arrive without foundation: BlockDAG restored verified buyback balances and built the infrastructure to display their USDT value in real time before opening any new offer. The $0.03 window is presented not as a standalone announcement but as the next step in a sequence that started with delivery.

USDT Buyback settlements will be processed in batches under the updated regulatory and compliance structure, and additional processing time will be required as each batch is completed. The structure, per the announcement, is designed to move forward rather than stay open indefinitely.

Recap

Cardano's 26% week was built on an AI payment integration that opens a new transaction lane for the token, with $0.31 the next target if the $0.25 zone holds through a daily close and retest. NEAR's 80% move was built on confidential perpetuals, a product the report describes as one no major protocol had offered before, with $5 as the analyst target. BlockDAG, positioned ahead of those moves, has raised its USDT Buyback Price from $0.02 to $0.03 for a 7-day window, with direct BDAG at $0.00000017 and both Legacy and New BDAG purchases building eligible allocations.
