Nucleon

Rejected venues wait the longest for re-review; a rejection has to earn another look before the scheduled date.

Nucleon’s surveyed base product is xCFX liquid staking: users deposit CFX, receive an interest-bearing claim on CFX delegated to Conflux PoS providers, and wait through the network withdrawal period to redeem. The 2026-08-16 survey measured about $0.57M of base xCFX TVL entirely on Conflux, plus a separately reported optional $0.20M pool2 suffix. The AMM suffix is not the core receipt. Because the base stake, contract and redemption all settle on an unapproved chain, the version-1 rejected-chain dossier controls.

Kill criteria: the events that revoke this verdict
• Conflux passes a versioned Ketju chain review with no active chain kill criterion
• An economically separate Nucleon staking product develops meaningful liquidity on an approved chain

The research file

Mechanism and perimeter applicability

Nucleon documents xCFX as the interest-bearing ERC-20 claim on CFX staked into its Conflux PoS pool. The protocol contract elects staking providers and compounds rewards while providers do not directly custody user assets. The survey adapter values xCFX total supply through the exchange-room redemption estimate. Its separate pool2 function counts CFX/NUT and CFX/xCFX LP tokens in MasterChefV2; those optional AMM positions are excluded from the base staking claim.

Control, loss and exit boundary

Official materials identify the xCFX token, exchange-room proxy and DAO multisig and state that Conflux staking carries slashing and offline-penalty risk. Nucleon reports one Hacken audit, but its public documents do not establish current provider identities and realized concentration, proxy-admin and multisig thresholds, remediation against deployed bytecode, slashing or incident allocation, or proposed-size secondary liquidity. Native xCFX-to-CFX withdrawal is valued when confirmed and follows the Conflux PoS period, documented as about 14 days.

Current observation and lifecycle

The DefiLlama API read on 2026-08-16 classified Nucleon as Liquid Staking and reported approximately $0.57M of base TVL on Conflux plus approximately $0.20M in pool2. The adapter still reads live xCFX supply and the exchange-room redemption estimate, and current Conflux ecosystem documentation still identifies Nucleon as a liquid-staking derivative. This supports active base coverage without treating optional Swappi LP positions as mandatory.

Why the chain dossier decides

Every base xCFX mint, PoS allocation, reward update and native redemption depends on Conflux eSpace and Conflux consensus. No approved-chain venue provides the same native CFX staking claim. The shared version-1 rejected-chain dossier therefore controls before liquid-staking quality or size. Reopen if Conflux passes a versioned Ketju chain review, then verify exact deployed authorities, provider concentration, audits and incidents, slashing allocation and proposed-size native and secondary exits.

The claims above trace to these. Where a number could not be independently verified, the thesis says so.

Inherited controls

The verdict above grades the protocol layer. Every position also inherits the asset it holds and the chain it settles on. The least safe layer sets the position’s grade, and the position table names which one that is.
