AlvoSwap Whitepaper

1.1 From Constant‑Product Pools to Concentrated Liquidity

Decentralized exchange began with Uniswap v1 (2018), which demonstrated that a simple constant‑product curve x • y = k could crowd‑source liquidity permissionlessly. Uniswap v2 (2020) generalized trading pairs and catalyzed the "liquidity mining" era; Curve optimized for tightly‑pegged assets; Balancer introduced custom weights and indexes; SushiSwap forked the model across dozens of chains. In 2021, Uniswap v3's concentrated‑liquidity positions turned LPs into granular market‑makers, boosting capital efficiency by up to 4,000%.

1.2 Liquidity Splinters Across Chains

While these advances squeezed more volume out of every on‑chain dollar, they did nothing to stop liquidity from fracturing. Value is now siloed on Ethereum, BNB Chain, Solana, TON, Polygon, dozens of optimistic and ZK roll‑ups, and emerging Bitcoin L2s. Moving assets between them typically means:

• Locking tokens in a custodial bridge contract.
• Waiting minutes to hours for confirmations.
• Receiving a wrapped IOU that introduces new smart‑contract risk.

Since 2021, bridge exploits (Poly Network $610M, Wormhole $326M, Ronin $625M, Multichain $126M, etc.) have erased > US $2 billion, underscoring how fragile the status quo is.

1.3 Hidden Costs of Fragmentation

• Capital Inefficiency: LPs must split funds across chains, draining depth and raising slippage everywhere.
• User Friction: Traders juggle multiple wallets, RPCs, gas tokens, and UX paradigms.
• MEV & Latency Arbitrage: Bots exploit price gaps created by slow bridges and thin books.
• Governance Dilution: Communities splinter; protocol upgrades roll out inconsistently.

1.4 Why Inter‑chain Swaps Must Be Trust‑Minimized

The logical alternative is an AMM that treats disparate chains as a single liquidity surface and moves value through lightweight, crypto‑economic messages rather than custodial vaults. To succeed, such a system must be:

• Trust‑Minimized – no multi‑sig guardians or wrapped IOUs.
• Composable – callable by any contract on any connected chain.
• Capital‑Efficient – matching (or beating) slippage of single‑chain DEXs.
• Simple – UX identical to a normal swap; the cross‑chain hop is abstracted away.

1.5 AlvoSwap's Mandate

AlvoSwap fuses a next‑gen concentrated‑liquidity AMM with a LayerZero‑based, zk‑proof‑relayed messaging layer. Liquidity providers deposit once on their home chain; traders route orders that atomically mint/burn liquidity shards on remote chains, settled in one transaction. The result is a single, unified liquidity layer spanning Ethereum, BNB Chain, Solana, TON, and native‑BTC Taproot assets—without custodial risk, without wrapped sprawl, and with execution speeds measured in seconds, not minutes.

2.1 High Slippage & MEV on Today's DEXs

Even after Uniswap v3's capital‑efficient design, deep liquidity still clusters around a handful of blue‑chip pairs. The "long tail" of tokens—where innovation often happens—trades in shallow pools that can move the price by 1–5% on a single $5k order. This slippage is amplified by miners–extractable value (MEV): bots detect the swap in the mempool, insert a "sandwich" of buy and sell transactions around it, bleed extra value from the trader, and walk away with instant, risk‑free profit. During market volatility, gas auctions for block priority can spike fees 10×, discouraging retail users altogether.

2.2 Siloed Liquidity on Single Chains

A token deep on Ethereum may be illiquid on Solana, and vice‑versa. Projects end up bribing LPs with inflationary rewards on every chain they expand to, duplicating pools and diluting liquidity. Arbitrageurs then ferry assets across bridges—locking capital, paying fees twice, and widening spreads in the meantime. Capital efficiency collapses: one dollar of stablecoin might need to be replicated four times just to sustain healthy markets across L1s and L2s. For institutions, this fragmentation inflates balance‑sheet risk; for retail, it simply means "the price is worse here."

2.3 Complex UX for Cross‑Chain Operations

The average cross‑chain swap today resembles a mini‑treasure‑hunt:

1. Swap on chain A to the bridge‑approved asset.
2. Use a third‑party website to lock funds and mint a wrapped token on chain B.
3. Add a new RPC, import a second wallet, and secure native gas tokens for chain B.
4. Finally swap the wrapped asset into the desired token—hoping no bridge exploit occurs in the interim.

Each step introduces smart‑contract risk, extra fees, and cognitive overload. For newcomers, it is indistinguishable from magic—and not the good kind.

3.1 Permissionless & Composable

AlvoSwap's contracts are MIT‑licensed, deployed without admin keys, and surfaced through fully on‑chain registries. Anyone can create a pool, provide liquidity, or integrate the router without whitelisting. Modules—AMM curves, cross‑chain adapters, oracle hooks—adhere to a common interface (IAlvoModule), so third‑party builders can plug in custom math or settlement layers with a single import. The protocol emits rich, indexable events, enabling subgraphs and analytics dashboards to compose on top of AlvoSwap just as easily as they do on Uniswap or Curve.

3.2 Security‑First Smart Contracts

Every critical contract is written in Solidity 0.8 with overflow checks, fuzz‑tested using Echidna, and formally specified in Scribble. Two independent audits (Trail of Bits & Spearbit) precede mainnet deployment, and a 60‑day Immunefi bug‑bounty program parallels the audit window. Critical upgrades are gated by a 7‑day DAO timelock and can only be executed by the on‑chain Governance Executor, ensuring that even maintainers cannot fast‑track changes. Runtime circuit‑breakers enforce liquidity‑ratio bounds and halt pools if invariant drift exceeds 1 bps.

3.3 User‑Centric UX

From the first click, the dApp abstracts away network complexity: a single interface detects the user's wallet chain, surfaces balances across all supported networks, and estimates gas in the token the user already holds. Cross‑chain swaps bundle bridging, liquidity routing, and slippage protection into one signature—confirmed or reverted atomically. A built‑in Tx Simulator previews price impact, MEV probability, and post‑trade portfolio allocation before the user signs. Accessibility features include dark‑mode contrast, screen‑reader ARIA labels, and lag‑tolerant WebSocket fallbacks for users on high‑latency connections.

3.4 Sustainable Token Economy (Distribution‑Only Model)

ALVO's monetary policy is deliberately minimalist: a fixed max supply, no emissions, no inflationary yield farming. Value accrual stems solely from product usage—20% of every swap fee is routed to the DAO treasury. The treasury budget is streamed to ongoing audits, grants, and liquidity bootstrapping as approved by veALVO governance, keeping long‑term incentives aligned without diluting holders. This distribution‑only design eliminates "ponzi‑nomics," reduces regulatory ambiguity, and focuses community attention on building real utility rather than chasing APRs.

AlvoSwap's Core AMM Engine is a concentrated‑liquidity constant‑product market maker inspired by Uniswap v3 but extended in three dimensions:

• Adaptive Tick‐Spacing – The pool deployer selects a volatility tier (e.g., 5 bps, 30 bps, 100 bps). Tick‑spacing is set algorithmically from on‑chain volatility oracles and can tighten during periods of high volume to maximise capital efficiency without redeploying the pool.
• Vault‐Separated Balances – Token balances are held in an ERC‑4626‑compatible Vault contract while the AMM only tracks virtual reserves. This isolates deposit risk from swap logic and enables flash‑loan‑free rebalancing.
• Dual‐Curve Routing – Each swap traverses a primary constant‑product curve and, if the trade would cause > 0.3% price impact, automatically spills into a stable‑swap sub‑curve (à la Curve) for the portion near parity, reducing slippage on correlated pairs.

Liquidity Positions

LPs mint an ERC‑1155 "Range NFT" that encodes:

• lower/upper ticks,
• liquidity amount,
• fee‑tier, and
• cross‑chain flag (true if mirrored in a satellite pool).

Positions accrue two balances: collected fees and unclaimed rewards from LayerZero relayer rebates. Both are claimable in a single collect() call.

Fee Mechanics

Swap fees are variable (0.01%–1%) and split:

• 80% → distributed pro‑rata to active LPs in the tick range;
• 20% → sent to the DAO treasury (no buy‑back in the distribution‑only model).

A dynamic fee controller, governed by veALVO, can widen or narrow the band per pool to respond to volatility spikes.

Price Oracle & TWAP

Every swap pushes a cumulative sqrt‑price to a storage slot, enabling gas‑cheap TWAP reads for lending protocols. Because virtual reserves cannot be manipulated without equivalent real reserves entering the vault, the oracle is manipulation‑resistant for time‑windows ≥ 30 s.

Gas Optimisations

• Inline assembly for the inner swap loop;
• Bitmap‑compressed tick bitmaps (1 bit ≈ 1 tick);
• immutable pool parameters to shrink runtime storage;
• ERC‑2612 permits on liquidity mint to save an extra approval.

Upgradeability & Governance Hooks

Core pools are deployed with EIP‑1967 minimal proxies pointing to a frozen implementation. Upgrades require a two‑step DAO vote → timelock and result in a new implementation; existing pools can opt‑in via the factory's upgradePool().

Architectural Overview

The Cross‑Chain Engine (CCE) sits between the Core AMM and a trust‑minimized messaging layer built on LayerZero V2 with zk‑proof relayers for independent verification. Instead of locking tokens in a bridge and minting wrapped IOUs, the CCE treats each connected chain as a liquidity shard:

1. A Canonical Vault on Ethereum holds the source tokens.
2. Satellite Pools on BNB Chain, Solana (SPL), TON (Jetton), and Bitcoin Taproot track virtual balances that correspond 1‑to‑1 with reserves in the Canonical Vault.
3. Cross‑chain swaps atomically adjust these virtual balances and settle the user's output tokens on the destination chain—no custodial escrow, no wrapped assets.

Message Flow

User → Router (Chain A) → LayerZero Endpoint → zk‑Proof Relayer → Executor (Chain B)

Step 1 – Commit: The user calls swapCrossChain() on Chain A. The Router locks the input amount in the local Vault and emits a SwapIntent event.

Step 2 – Relay: The event is packed into an lzPacket, signed by an Optimistic Verifier, and forwarded to Chain B. A zk‑SNARK proving circuit verifies the packet's Merkle inclusion and the vault's solvency snapshot.

Step 3 – Execute: If the proof is valid, the Executor on Chain B debits the Satellite Pool's virtual reserve and transfers the output asset to the user.

Step 4 – Finalize: A receipt flows back to Chain A; the Router burns the locked tokens, maintaining global supply invariants.

Path‑Finding & Aggregation

A Path Oracle runs off‑chain, sampling gas prices, bridge fees, and pool depths every block. The Router queries this oracle to choose the lowest‑cost route among:

• Direct Path: Chain A ↔ Chain B (one hop)
• Multi‑Hop: Chain A → Ethereum (canonical) → Chain B (two hops, cheaper when one leg has deep liquidity)

Route weights are recalculated every 30 seconds and broadcast on‑chain for transparency.

Gas Abstraction & Fee Model

Users pay gas once on the origin chain. Relayer fees on the destination chain are paid from a Relayer Stipend funded by the DAO treasury and replenished monthly via veALVO vote. Heavy arbitrageurs can attach an optional relayerTip to guarantee fastest inclusion.

Supported Networks (Launch Set)

• Ethereum Mainnet (canonical)
• BNB Chain (BEP‑20)
• Solana (SPL tokens)
• TON (Jetton standard)
• Bitcoin Taproot assets (via DLC adaptor)

Adapters for Arbitrum, Base, and Polygon zkEVM are in audited staging.

Developer Integration

• SDK: TypeScript / Rust clients expose swapCrossChain(), estimateGas(), and event listeners.
• Subgraph: Indexed cross‑chain TVL, volume, and settlement latency.
• Hooks: Composable callback interface onSwapFinalized() for pay‑for‑order‑flow and DeFi legos.

Threat Model

AlvoSwap's security design assumes the following adversaries:

• On‑chain attackers seeking re‑entrancy, overflow, or logic flaws.
• Bridge/relayer adversaries attempting packet replay or censorship.
• Governance capture via token accumulation or delegate‑bribing.
• Infrastructure compromises at RPC, DNS, or front‑end layers.

Preventive Controls

Runtime Protections

• Global Circuit Breaker: If pool price deviates > 1% from oracle TWAP or vault TVL drops > 2% intra‑block, swap() reverts chain‑wide until DAO review.
• Per‑Pool Pausability: LPs can vote‑signal a soft‐pause; requires DAO‑executed hard‑pause within 6 hours or pool auto‑unpauses.
• Rate‑Limiters: Cross‑chain Executor enforces 1‑tx/second per satellite pool, thwarting spam‑flood attacks.
• zk‑Proof Verification: All LayerZero packets embed Merkle roots of Canonical Vault balances; mismatches trigger automatic haltGlobal() across chains.

Governance & Upgrade Safety

• 7‑Day Timelock: Any contract upgrade or parameter change must survive a full week before execution.
• Opt‑In Migrations: Existing pools can elect to stay on legacy code; liquidity providers choose when to migrate.
• Emergency Veto: A 3‑of‑5 Security Council (elected every 6 months by veALVO) can veto malicious upgrades but cannot push new code unilaterally.

Monitoring & Incident Response

• On‑Chain Sentinels: Custom Grafana dashboards watch swap volume, TWAP drift, vault inflows, and satellite balances in real time.
• 24/7 PagerDuty: Critical alerts wake a rotating on‑call engineer within 3 minutes.
• Immunefi Bug Bounty: US $1M cap, paid 10% in ALVO + 90% in USDC; covers L1, L2, and CCE vulnerabilities.
• Post‑Mortem Policy: Public RCA published within 48 hours, including remediation timeline and treasury compensation plan if users are impacted.

Insurance & Recovery Mechanisms

• DAO Insurance Fund: 1% of swap fees accrue to an on‑chain fund capped at 5% of TVL, deployed only after DAO vote.
• Automated Safe‑Exit: If haltGlobal() is active > 72 h, users can exit positions at last confirmed oracle price, bypassing swap fees.

Token Overview

Design Rationale

• Deterministic Supply – A clearly defined hard cap eliminates inflation risk and simplifies long‑term valuation.
• Single Canonical Mint – All coins originate on Ethereum and move across other chains through audited, non‑custodial bridges. This prevents fragmented liquidity and guarantees one‑to‑one collateralisation.
• Governance‑Focused Utility – Holding AlvoSwap confers only voting and proposal rights in the on‑chain governance system, keeping the token's legal profile straightforward.

Token Allocation

Distribution Details

Key Characteristics

• Focused Token Utility – The hard‑capped supply follows a clear allocation strategy with emphasis on user motivation and liquidity mining to ensure sustainable ecosystem growth.
• Governance‑Only Rights – AlvoSwap does not provide revenue shares, fee rebates, or any other monetary benefit; its sole purpose is to grant proposal and voting power in the governance system.
• Transparent and Accountable Releases – All category unlocks and transfers are executed through audited time‑lock contracts that require on‑chain approval by the Decentralized Autonomous Organization.
• Regulatory Clarity – By avoiding reward mechanics and limiting utility to governance, the token is positioned as a digital membership instrument rather than a yield‑bearing security.
