CoinYQ Dossier

XCN changed its unit, its name and eventually the network where holders vote

The CHN conversion multiplied the token count by a thousand without making it a thousandfold gain. The Onyxcoin rename then kept that new unit, while lending, a Base bridge and Layer 1 voting changed what users could do with it. Following those choices separately explains why a familiar XCN ticker can lead to different products and participation routes.

The conversion changed the unit; the rename kept it

XCN did not begin as a fresh 2022 blank slate. Chain’s earlier CHN became the input to a conversion contract and exchange migration: one CHN was surrendered for 1,000 XCN. The code burned the CHN and issued the larger number of units, so a chart spanning the change must not read the unit jump as organic issuance.

The canonical Ethereum contract still calls itself “Chain” and records delegated vote checkpoints. It minted 21,537,311,000 XCN at deployment and exposes a migration mint path capped by a Solidity constant. Onyxcoin is therefore a later public identity wrapped around code whose internal name remembers Chain.

A Bittrex notice updated February 1, 2023 reports its completed change from Chain (XCN) to Onyxcoin (XCN), with wallets and trading enabled and no holder action required. This documents completion at that exchange by that date, not the first rename date across all markets. Unlike the CHN conversion, it kept the asset.

A lending relaunch and a bridge gave XCN different jobs

Onyx Protocol then used the name for a Compound-style lending product. Its 2023 v2 plan was unusually explicit: new money-market contracts did not alter XCN, staking or governance. Borrowing risk belonged to those markets, not automatically to every token balance.

OIP-35 connected Base by lock-and-mint accounting: Ethereum XCN was locked and an equal amount minted on Base; return burned the Base representation before releasing Ethereum collateral. The proposal also directed 100 million XCN to Base DEX liquidity.

That makes chain labels operational. The Ethereum address 0xa2cd…fb18 is canonical in the bridge docs, while Base 0x9c63…5e0c represents locked Ethereum units. A balance on one network cannot silently be treated as the governance balance on another.

Onyx Layer 1 brought voting to another asset and network

On Ethereum, governance weight came from staked XCN. The published path ran through a Governor, a 200 million affirmative-vote requirement and a Timelock that waited two days. A Guardian wallet could cancel before execution, meaning a vote was powerful but did not erase the emergency key.

The August 18, 2026 OIP-2 announcement made the change in participation concrete: it invited stXCN holders to vote through the Onyx Layer 1 app. That extended the documented route beyond legacy Ethereum staking, but the public proposal page did not reveal its result or execution payload. The announcement establishes who was invited and where, not that the proposal was carried out.

Older documentation and the 2025 white paper describe an L3 and Ethereum-only governance; the current product presents XCN as an Onyx Layer 1 asset. Naming stXCN made the new participation route concrete, but did not prove that every old parameter carried across. Advertised staking rates and fee burns remain adjustable program conditions.

Chain technology returns as a proposal, not a completed purchase

A September 2, 2026 community announcement linked an Onyx proposal to acquire Chain technology and intellectual property and said voting would open in about 24 hours. That is the dated announcement, not proof that the purchase closed. The linked blog was access-blocked in this review and the vote result was not independently obtained.

Chain’s separate corporate history dates to 2014, followed by the reported Stellar acquisition and Interstellar formation in 2018 and reacquisition in 2020. XCN does not itself document company equity, treasury redemption or software title. The proposed technology purchase would therefore be another product decision to judge on its terms, after a history in which the unit, the brand, lending contracts and voting network changed at different times.

Evidence and primary sources

Last evidence review: 2026-09-05

What is Onyxcoin?

Onyxcoin is the asset CoinGecko identifies as chain-2. XCN began as Chain’s successor token on Ethereum, later took the Onyxcoin name, bridged to Base and became the advertised gas, staking and governance asset of Onyx Layer 1.

What problem does Onyxcoin solve?

XCN changed its unit, its name and its products at different times. The 1:1,000 CHN conversion was not the later Onyxcoin rename. Lending, bridged balances and Layer 1 voting then added their own contracts and participation rules, so the familiar ticker no longer answers which product or voting route a user is choosing.

How does Onyxcoin work?

CHN holders migrated by surrendering one CHN to mint 1,000 XCN. Canonical Ethereum XCN can be locked to issue a 1:1 Base representation. Governance depends on a staking module, Governor, Timelock and Guardian, while monthly timelock and DAO release caps govern distribution. Current Layer 1 staking and governance add another generation whose live contracts and parameters must be checked.

The Layer 1 route announced on August 18, 2026 instead invites stXCN holders to vote in the Onyx governance app. Its public OIP-2 page did not expose the result or execution payload in the reviewed material. The website advertises 100 million proposal weight, 200 million affirmative votes, a two-day voting period and a two-day timelock; those published thresholds are not proof that the L1 module enforces every legacy rule.

Key facts

  • CoinGecko ID chain-2 is Onyxcoin (XCN), not an unrelated project named Chain.
  • Canonical Ethereum XCN: 0xa2cd3d43c775978a96bdbf12d733d5a1ed94fb18; Base bridge token: 0x9c632e6aaa3ea73f91554f8a3cb2ed2f29605e0c.
  • March 2022 conversion: 1 CHN became 1,000 XCN through CHN surrender and burn.
  • XCN-Token.sol minted 21,537,311,000 initially and records MAX_SUPPLY as 68,895,442,185.
  • Earlier research recorded an August 18, 2025 table with maximum 68,892,071,756, burned 20,489,639,348 and total 48,402,437,326 XCN. The live source no longer reproduces that table and explicitly declines to publish a current total. These are unreconfirmed historical figures, not current supply.
  • The recorded maximum is 3,370,429 below the code constant; subtracting recorded burns also gives 4,918 less than the stated total. Neither difference is reconciled.
  • Timelock releases 200 million XCN every 30 days until 1 March 2030; the DAO has a separate 200 million monthly cap with rollover.
  • Legacy Ethereum governance uses staked XCN, 200 million affirmative votes, a two-day Timelock and a Guardian cancellation path.
  • OIP-35 uses 1:1 lock/mint and burn/unlock for Base and allocated 100 million XCN to Base liquidity.
  • Onyx Protocol lending, current Layer 1 staking and Chain corporate technology are separate from passive XCN ownership.
  • The August 18, 2026 OIP-2 announcement directs stXCN holders to the Onyx Layer 1 voting app; the reviewed public page did not establish the proposal’s result or execution.

Frequently asked questions

Is chain-2 still Chain or Onyxcoin?

It is Onyxcoin (XCN). The Ethereum contract retains the internal name Chain, and exchanges rebranded Chain (XCN) to Onyxcoin without another asset swap.

Was CHN simply renamed XCN?

No. In March 2022, one CHN was surrendered and burned to mint 1,000 XCN. The later XCN-to-Onyxcoin change was the rename.

What is the maximum XCN supply?

The code records MAX_SUPPLY of 68,895,442,185 XCN. Earlier research recorded an August 18, 2025 table with maximum 68,892,071,756, burned 20,489,639,348 and total 48,402,437,326 XCN. The live source no longer reproduces that table and explicitly declines to publish a current total. These are unreconfirmed historical figures, not current supply. The recorded maximum is 3,370,429 below the code constant; subtracting recorded burns also gives 4,918 less than the stated total. Neither difference is reconciled.

Does any XCN balance vote?

Ordinary XCN ownership alone should not be treated as voting eligibility. Legacy Ethereum governance used staked XCN; the August 18, 2026 OIP-2 announcement invited stXCN holders to the Layer 1 app. These are different participation routes, and the reviewed OIP-2 page did not establish the result or execution.

Is Base XCN the same contract?

No. It is a bridged representation at 0x9c632…5e0c backed through lock/mint and burn/unlock against canonical Ethereum XCN.

Does XCN represent shares in Chain?

No reviewed source grants Chain equity, treasury redemption or software ownership to an ordinary XCN balance. The September 2, 2026 technology-acquisition announcement describes a proposal; it is not evidence of a completed corporate transaction or a share issue to holders.
