FENswap

Source assets enter as stablecoin value and leave the public quote surface as P-FEN.

FENswap converts supported source assets into a stablecoin-value quote and presents the result as expected P-FEN.

The page is a public quote-review surface. It shows source value, expected receipt output, fee and slippage boundaries, quote expiry, and receive-state checks without exposing protected routing controls reserved for user protection and ecosystem continuity.

FENswap

Bring outside liquidity into the FENpresale path.

FENswap is the gateway for bringing external liquidity into the FEN ecosystem. Users connect a wallet, select a supported source asset, preview the expected P-FEN amount, and enter the FENpresale flow. Supported source assets are swapped into stablecoin value to determine the final amount of P-FEN acquired. P-FEN is a non-transferable ERC-20 presale receipt token.

Abstract 1. Section Abstract

FENswap is a quote-method section, not a generic swap page.

This section models FENswap as a public quote discipline. The relevant research object is not a marketing claim that many chains are available, but a constrained translation: supported source assets become stablecoin-value quote context, and the visible receive state remains P-FEN until the reader enters the FENpresale claim model. The design also records what the public should not see: protected routing controls, liquidity safeguards, abnormal-flow checks, and execution details.

Quote method: expose enough structure for review while keeping protected controls out of the public UI.

Research Questions

Research Question 1. RQ-FS-01

How can a quote interface avoid implying unlocked FEN receipt?

By declaring P-FEN as the visible receive state, separating stablecoin-value normalization from presale entry, and refusing to describe the quote as claimed inventory.

Research Question 2. RQ-FS-02

What can be shown publicly without exposing route exploitation surfaces?

The interface can show supported source families, asset symbols, plan labels, quote-expiry concepts, gas/fee separation, and P-FEN output while keeping protected routing controls reserved for user protection.

Research Question 3. RQ-FS-03

What is the terminal public state of the FENswap section?

The terminal public state is a reviewed P-FEN receipt preview and handoff into FENpresale evidence, not claimed FEN, pooled FEN, or N research supply.

Formal Claim Register

Claim	Statement	Evidence	Boundary
Formal Claim 1. FC-FS-01	FENswap output language is P-FEN first.	The receive card, route plans, metrics, and quote console all preserve P-FEN as the public output label.	The section does not call the output unlocked FEN or reward-eligible FEN.
Formal Claim 2. FC-FS-02	Source assets are public catalogue entries, not exposed protected controls.	The source catalogue lists route families and assets as public quote-review labels.	Protected routing controls, liquidity safeguards, abnormal-flow checks, and final execution details stay excluded.
Formal Claim 3. FC-FS-03	Stablecoin-value normalization is a quote method, not a final settlement promise.	The flow diagram separates source amount, stablecoin-value basis, receipt preview, presale handoff, and FENtrust checkpoint.	A preview plan cannot be read as a guarantee that every route is live, executable, or final at the quoted terms.

Invariant Ledger

Invariant 1. INV-FS-01

Every visible receive path remains receipt-denominated.

Metric cards, quote badges, and supported asset labels use P-FEN language before presale claim language.

Invariant 2. INV-FS-02

Quote components remain separable.

Guardrails require gas, route fee, slippage, quote expiry, and receive output to remain distinct concepts.

Invariant 3. INV-FS-03

Protected route intelligence is not rendered.

The public catalogue names source assets without protected routing controls, liquidity safeguards, abnormal-flow checks, or execution details.

Evidence Matrix

Row	Artifact	Observation	Limitation
Evidence Row 1. FS-01	public FENswap source catalogue	Defines public source-chain families and source asset labels for quote review.	Catalogue presence does not prove final route availability at execution time.
Evidence Row 2. FS-02	public FENswap quote preview model	Defines preview plan count and route labels that resolve toward P-FEN output language.	Preview plans are public structure, not protected execution traces.
Evidence Row 3. FS-03	components/nexus/fen-acquisition-console.tsx	Keeps the working quote surface visible inside the section.	The console is a public preview surface and does not expose privileged route or custody controls.

Limitations And Non-Claims

Limitation 1. L-FS-01

No route execution guarantee

The section describes preview logic and public source labels; final route execution, if available, remains subject to live checks and protected controls.

Limitation 2. L-FS-02

No unlocked-FEN representation

A FENswap quote cannot be read as unlocked FEN, FENpool inventory, or N migration inventory.

Limitation 3. L-FS-03

No protected formula disclosure

Protected routing controls, liquidity safeguards, abnormal-flow checks, and execution details remain outside the public monograph to reduce abuse and protect users.

FENswap engineering flow

The quote pipeline separates source assets, stablecoin value, receipt output, and presale claim state.

This diagram is the public quote grammar. It prevents the common failure mode where an acquisition page compresses source input, stablecoin value, receipt output, claimed FEN, reward eligibility, and research migration into one vague swap sentence.

The receive surface remains receipt-based throughout FENswap.

01 / source asset selectionsupported inputThe user chooses a public source asset from the supported catalogue. The UI describes chain family, asset symbol, and review status without rendering protected routing controls.

02 / stablecoin-value normalizationquote basisThe source amount is converted into stablecoin-value language so source volatility, route review, gas, and receipt output remain separate concepts.

03 / receipt previewP-FENThe visible receive output is P-FEN. The page must not describe this step as unlocked FEN, reward-eligible FEN, or N research inventory.

04 / presale handoffFENpresaleFENswap hands the user into the P-FEN receipt path. P-FEN remains non-transferable and later burns into the claim schedule when the presale has finalized.

05 / trust checkpointFENtrustThe quote surface points back to source evidence, token-flow rules, and non-custodial boundaries before any final user action is described.

Every visible receive amount on this page should remain P-FEN until the user is reading FENpresale claim language.

Quote model

Expected P-FEN, stablecoin value, fee, and slippage review.

FENswap exposes only the information a participant needs to review a quote: source asset, stablecoin-value basis, expected P-FEN, route fee, slippage, quote expiry, and receive-state review.

FENswap is a quote and entry surface, not a promise that every source path is live for final execution.

The visible output remains P-FEN until the user enters the FENpresale receipt path.

Gas, route fee, slippage, quote expiry, and receive review are separate public concepts.

Protected routing controls, liquidity safeguards, abnormal-flow checks, and execution details stay out of the public UI to reduce abuse and protect users.
