Ten Chains Become Two: Parallel Assets, Explained

Fluxers! FLUX exists as a token on ten other chains. That is being consolidated down to two. This article explains which chains survive, what holders on the retiring chains have to do, when the deadlines fall, and what the new bridge actually guarantees.

If you hold FLUX on a parallel chain, the short version is: check which chain, and check it before March 2027.

Which chains survive

Ethereum and BNB Chain survive. Balances there are carried across to new contracts by snapshot. Holders do nothing.

The other eight are retired: Base, Polygon, Avalanche, Ergo, Algorand, Solana, Tron and Kadena.

The timeline

• March 2027, block 3,450,000: the eight retiring chains become one-directional. Balances remain redeemable back to the main chain and mining claims are still collectable, but nothing can be swapped into them.
• July 2027: the allocation is cut, at the block where it is exhausted and PNR activates.
• August 2027, block 3,880,000: the chains shut down. After that, unclaimed balances go to the Foundation.

Ethereum and BNB Chain move to their new contracts earlier than this.

That final forfeiture rule is the sharp edge, and it exists for a specific reason: roughly a quarter of what operators have accrued on these chains has never been claimed. Without a closing rule, that balance sits unresolved forever. With one, people have eighteen months of notice to collect what is theirs.

How much is actually exposed

This is where the measured numbers are much more reassuring than the raw supply figures, and it is worth understanding why the two differ so wildly.

Each parallel asset was minted at its full nominal amount — 440,000,000 on most chains — and the issuer still holds nearly all of it. Quoting total supply would therefore tell you almost nothing. The figure that matters is what has actually left the issuer’s hands, and computing that required the issuer’s own address registry.

Measured on 3 and 4 September 2026:

• Held outside issuer addresses, all ten chains: 223,027,781.21 FLUX
• Of that, on the two surviving chains: 97.21% — needs no holder action at all
• On the retiring chains, exposed to the redemption window: 6,226,900.80 FLUX — 2.79%

So the consolidation touches under three percent of circulating parallel-asset balances, and the rest is carried across by snapshot.

Two of those chains needed a different method to measure at all, which tells you something about the state of the ecosystem: Kadena’s token contract exposes no total-supply function, so supply was recovered by enumerating every account across its twenty chains and summing. Tron needed the block explorer’s API rather than the node’s. Both are scripted and published, so you can re-run them.

The new bridge

The current bridge backs parallel assets with FLUX held at bridge addresses. The replacement is mint-and-burn: minting on a parallel chain requires locked backing on the main chain, so the total can never exceed what exists. Supply on each chain becomes provable and capped by the contract itself.

The guards around it:

• A 3-of-4 signing quorum for mint, release and upgrades.
• A 1-of-4 emergency pause — any single guardian can stop it.
• A per-chain cap of 250,000,000 FLUX.
• A rate limit of 10,000,000 FLUX per chain per day.
• A 48-hour delay on any upgrade, during which a single guardian can cancel it.

Independent audit comes before deploy, with reserve accounting published throughout, and Ethereum and Base go first. The destination is immutability — the upgrade path exists as a bring-up safety net while the contracts build an operating record, and renouncing it on chain is the stated end point.

Proof of reserve

One thing the new contracts enable that the old ones could not: they become the home of a continuously verified proof that minted supply across every chain, plus the main chain, equals total issuance. A live proof-of-reserve for FLUX itself.

That matters beyond the bridge. Reconciling supply across eleven chains is what makes a serious conversation about supply policy possible, and that conversation is coming: once the full reconciliation is public, a proposal goes to the community in the open. The candidates are a hard cap, freezing issuance at what has been produced, or letting the tail continue — and because operators are paid from that issuance, they get the numbers before they are asked to weigh in.

What to do now

If your FLUX is on Ethereum or BNB Chain: nothing. If it is on any of the other eight, you have until March 2027 before those chains go one-directional and until August 2027 before they shut down. Redeeming back to the main chain is the safe move, and there is no reason to leave it late.
