If you’ve ever wondered what happened to the Cipher CPR airdrop back in 2021, you’re not alone. Many crypto enthusiasts still hear the name “Cipher [Old]” on tracking sites and wonder if they missed out or how the distribution actually worked. This article pulls together everything the project publicly shared, breaks down the technical backdrop, and shows you how to verify whether you ever qualified.
Cipher (CPR) is a utility token launched on April 9, 2018 that originally ran on the Ethereum blockchain before moving to Polygon PoS. The team, spread across India, the United Kingdom and NewZealand, designed CPR to act like a share in the company - holding CPR gives you a slice of any future revenue streams.
The token’s total supply is fixed at 1.08billion CPR, with a self‑reported circulating supply of about 186.28million as of early 2025. Its contract on Polygon is 0xaa404804ba583c025fa64c9a276a6127ceb355c6, a address that replaced the older Ethereum contract after the migration.
In mid‑2021 Cipher ran an official airdrop titled “CIPHER (CPR) ASSET AIRDROP 2021 CONDUCTED ON CMC”. The distribution used CoinMarketCap’s (CMC) promotional platform, which at the time was a go‑to channel for projects wanting instant exposure.
Key points from the roadmap:
The airdrop was part of a broader push that also saw exchange upgrades on Cifinex and the launch of the Polygon contract.
While Cipher never released a detailed whitelist, the publicly shared criteria hinted at three main eligibility buckets:
After verification, Cipher sent the new Polygon‑based CPR directly to the qualifying wallet addresses. Because the migration required users to switch contracts, many participants reported a brief period of confusion-some thought they needed to claim a second time, while others missed the airdrop entirely.
The move from Ethereum to Polygon PoS (Proof‑of‑Stake) was billed as a “Powerful ERC‑20 version on Polygon”. The advantages were clear:
That technical upgrade was tightly coupled with the airdrop-by rewarding users with the Polygon version, Cipher hoped to accelerate adoption of the cheaper network.
Following the airdrop, CPR’s market cap nudged upward, but the token has been highly volatile. Highlights:
Attribute | Value |
---|---|
Total Supply | 1.08billion CPR |
Circulating Supply (2025) | 186.28million CPR |
Current Network | Polygon PoS |
Contract Address | 0xaa404804ba583c025fa64c9a276a6127ceb355c6 |
All‑time High (Feb2024) | $0.004065 per CPR |
24‑hour Range (Oct2025) | $0.00004791 - $0.00006803 |
Even with the airdrop’s short‑term boost, CPR’s price has settled near the lower end of its 2025 range. The token’s utility-providing access to Cipher’s business‑application suite-has not seen major new releases since 2023, which likely dampens demand.
The 2021 airdrop illustrates a common pattern among 2018‑2021 crypto projects:
As of October2025, Cipher’s official channels show limited activity. The project is still listed under “Cipher [Old]” on major trackers, indicating that a newer version (or a completely different initiative) may have replaced it. For anyone still holding CPR, the token remains tradeable on a handful of small exchanges, but liquidity is thin.
If you think you might have qualified for the 2021 airdrop, here’s a quick checklist:
Remember, the airdrop did not require KYC, so any wallet that meets the criteria should have received the allocation automatically.
No. The airdrop was distributed directly to qualifying wallets without any transaction or claim fee. Users only needed to hold the appropriate amount of CPR before the migration deadline.
Unfortunately, the claim window closed in late 2021. If you missed it, the only option is to buy CPR on the secondary market.
The "Old" label indicates that the original Cipher token contract has been superseded by a newer version or a different initiative. Tracking sites keep the tag to differentiate the legacy token from any newer releases.
All CPR holdings were automatically swapped to the Polygon contract address 0xaa404804ba583c025fa64c9a276a6127ceb355c6. Users could continue to trade or use the tokens within Cipher’s ecosystem, though activity has slowed in recent years.
Investment potential depends on whether Cipher revives its product roadmap. Current low liquidity and modest price action suggest caution; treat CPR as a speculative asset.
