Which Sphere this page covers
This profile concerns the historical SPHR cryptocurrency, later represented as a token on Ubiq. It does not cover every project using Sphere in its name, and it should not be confused with a similarly named company’s shares. Tickers and brand words are not unique asset identifiers.
The project’s original announcement thread records that Sphere had previously been called ChronoSphere. That history helps identify the asset in older records, but a name match alone is insufficient to authenticate a wallet, exchange listing or claimed successor.
The documented 2019 migration
In a March 16, 2019 update, the project’s announcement account said the proof-of-stake SPHR network had been snapshotted at block 1,567,140 the previous day and moved to Ubiq. It described a one-to-five conversion: one old unit corresponded to five new tokens.
The announcement identifies the resulting asset as a Ubiq-based token and states that the old network’s tokens would no longer be supported by the development team or traded on the named exchange. This is the significant historical event for interpreting an old SPHR balance.
The primary announcement describes a move from the old SPHR chain to Ubiq. ERC20-style token compatibility does not mean a token necessarily resided on Ethereum.
A token does not inherit the host coin’s issuance
After a migration onto a host blockchain, the token relies on that network for transaction processing. It does not automatically receive the host chain’s block rewards or acquire the same supply policy as the native currency. Token issuance depends on its own contract and rules.
Current total and circulating SPHR supply remain unconfirmed. Establishing either would require inspecting the correct deployed contract and relevant balances.
Historical conversion is not a current recovery offer
The old announcement discussed exchange-assisted conversion and later manual claiming. It does not establish that a manual recovery process remains available in October 2026. A historical ratio is therefore not an instruction to send old coins to a newly advertised address.
For an existing holding, record whether it is on the original network or Ubiq. Preserve the wallet and transaction history before attempting any conversion. The existence of a token with the same name on another chain does not demonstrate an authorized migration.
What remains uncertain today
This update confirms the historical migration from the project’s own announcement. It has not established a current product roadmap, supported recovery service or reliable trading route. That is not enough to assign a formal shutdown date.
The page is retained because migration history and asset identity remain useful to holders finding old balances. A factual explanation of which asset exists on which chain is more durable than speculation about a legacy token’s next trading move.
