NANA-SUCKERS-V5: Cross-Chain Bridging

What Are Suckers?

Suckers enable cross-chain token transfers between Juicebox projects. When a user burns tokens on one chain, they receive equivalent tokens on another chain. The sucker redeems locally and bridges funds to the peer network.

Supported Bridges

• JBOptimismSucker - Ethereum ↔ Optimism
• JBBaseSucker - Ethereum ↔ Base
• JBArbitrumSucker - Ethereum ↔ Arbitrum

Core Functions

// Prepare tokens for bridging (burns locally)
function prepare(
    uint256 projectTokenAmount,
    address beneficiary,
    uint256 minTokensReclaimed,
    address tokenToReclaim
) external returns (uint256 terminalTokenAmount);

// Bridge outbox tree to remote chain
function toRemote(address token) external payable;

// Claim tokens on remote chain with merkle proof
function claim(JBClaim[] calldata claims) external;

// Get merkle root for verification
function outboxTreeRoot(address token) external view returns (bytes32);

Requirements for Projects

• Present on both chains with same project ID
• 100% cash out rate enabled
• Owner minting enabled
• ERC-20 tokens deployed on both chains

---

NANA-BUYBACK-HOOK-V5: Token Buybacks

Purpose

Automatically routes payments through Uniswap V3 when swapping yields more tokens than direct minting. Acts as both a data hook and pay hook.

How It Works

1. beforePayRecordedWith() compares: mint tokens vs. swap tokens
2. If swap is better, specifies this contract as pay hook with swap amount
3. afterPayRecordedWith() executes swap, burns received tokens, re-mints with reserved rate

Core Functions

// Set Uniswap pool for a project
function setPoolFor(
    uint256 projectId,
    address token,
    uint24 fee,
    uint32 twapWindow,
    uint256 twapSlippageTolerance
) external;

// Get pool configuration
function poolOf(uint256 projectId, address token)
    external view returns (IUniswapV3Pool);

// Data hook: determine payment route
function beforePayRecordedWith(JBBeforePayRecordedContext calldata context)
    external view returns (uint256 weight, JBPayHookSpecification[]);

// Pay hook: execute swap if beneficial
function afterPayRecordedWith(JBAfterPayRecordedContext calldata context)
    external payable;

---

NANA-SWAP-TERMINAL-V5: Multi-Token Acceptance

Purpose

Accept payments in any ERC-20 token and automatically swap to ETH/native token via Uniswap V3.

Flow

1. User pays with any token (e.g., USDC)
2. Terminal swaps to ETH via configured Uniswap pool
3. ETH forwarded to primary terminal
4. Tokens minted for beneficiary

Core Functions

// Pay with any token (auto-swaps to ETH)
function pay(
    uint256 projectId,
    address token,              // Any ERC-20
    uint256 amount,
    address beneficiary,
    uint256 minReturnedTokens,
    string calldata memo,
    bytes calldata metadata     // Can include swap params
) external returns (uint256 beneficiaryTokenCount);

// Configure default Uniswap pool for token
function addDefaultPool(
    uint256 projectId,
    address token,
    IUniswapV3Pool pool
) external;

• reserveFrequency: Auto-mint 1 bonus per N purchased
• category: Grouping for organization
• encodedIPFSUri: Artwork/metadata location
• allowOwnerMint: Owner can mint directly
• transfersPausable: Can restrict transfers

Core Functions

// Data hook: specify NFT minting
function beforePayRecordedWith(JBBeforePayRecordedContext calldata context)
    external view returns (uint256 weight, JBPayHookSpecification[]);

// Pay hook: mint NFTs based on payment
function afterPayRecordedWith(JBAfterPayRecordedContext calldata context)
    external payable;

// Cash out hook: burn NFTs to reclaim funds
function afterCashOutRecordedWith(JBAfterCashOutRecordedContext calldata context)
    external payable;

// Get tiers for a hook
function tiersOf(
    address hook,
    uint256[] calldata categories,
    bool includeResolvedUri,
    uint256 startingId,
    uint256 size
) external view returns (JB721Tier[]);

// Adjust tiers (add/remove)
function adjustTiers(JB721TierConfig[] calldata tierConfigs) external;

// Owner mint from specific tiers
function mintFor(
    uint256[] calldata tierIds,
    address beneficiary
) external returns (uint256[] tokenIds);

REVNET-CORE-V5: Autonomous Treasury Networks

What Is a Revnet?

A Revnet is an unowned Juicebox project that operates autonomously after deployment. The deployer contract owns the project NFT, implementing hooks and delegating limited permissions.

Deployer Options

Deployer	Features
BasicRevnetDeployer	Standard revnet
PayHookRevnetDeployer	+ custom pay hooks
Tiered721RevnetDeployer	+ tiered NFT support
CroptopRevnetDeployer	+ public posting

Key Concepts

Stages: Revnets progress through stages with different parameters

• Initial weight, price ceiling, price floor
• Reserved rate distribution
• Boost periods for early supporters

Premint: Tokens minted to beneficiaries at launch

Boost: Temporary increased token allocation for specified recipients

REVDeployer Functions

// Deploy a new revnet
function deployFor(
    uint256 revnetId,
    REVConfig calldata configuration,
    JBTerminalConfig[] calldata terminalConfigurations,
    REVBuybackHookConfig calldata buybackHookConfiguration,
    REVSuckerDeploymentConfig calldata suckerDeploymentConfiguration
) external returns (uint256 projectId);

// Data hook: route payments through buyback
function beforePayRecordedWith(JBBeforePayRecordedContext calldata context)
    external view returns (uint256 weight, JBPayHookSpecification[]);

// Cash out hook: extract fees
function afterCashOutRecordedWith(JBAfterCashOutRecordedContext calldata context)
    external payable;

---

CROPTOP-CORE-V5: Public NFT Posting

What Is Croptop?

Croptop opens a project's NFT collection for public contributions. Anyone can post new NFT tiers if they meet criteria set by the project owner.

CTPublisher Functions

// Configure posting criteria
function configurePostingCriteriaFor(
    IJB721TiersHook hook,
    uint256 category,
    uint256 minimumPrice,
    uint256 minimumTotalSupply,
    uint256 maximumTotalSupply,
    address[] calldata allowedAddresses
) external;

// Post new NFT and mint initial copies
function mintFrom(
    IJB721TiersHook hook,
    JBDeploy721TierConfig[] calldata tierConfigs,
    address beneficiary,
    address payable feeBeneficiary,
    bytes calldata additionalPayMetadata
) external payable;

// Get posting criteria
function allowanceFor(IJB721TiersHook hook, uint256 category)
    external view returns (CTAllowedPost);

// Get tier data for URIs
function tiersFor(IJB721TiersHook hook, string[] calldata uris)
    external view returns (JB721Tier[]);

Posting Flow

1. Owner calls configurePostingCriteriaFor() with price/supply requirements
2. Anyone posts via mintFrom() with tier config and payment
3. System validates against criteria (price ≥ minimum, supply within range)
4. NFT tier created, fee (1/20th) sent to fee treasury
5. Beneficiary receives initial mint

---

Fee Structure

Standard Fees (2.5%)

Applied by JBMultiTerminal on:

• Payouts to wallets (project-to-project exempt)
• Surplus allowance withdrawals
• Cash outs with < 100% cash out rate

Fee Processing

• Fees route to Project #1 (protocol treasury)
• "Held fees" mode allows 28-day refund window
• Feeless addresses can be registered for exemption

---

Protocol Constants

// Native token identifier
address constant NATIVE_TOKEN = 0x000000000000000000000000000000000000EEEe;

// Max values
uint256 constant MAX_RESERVED_RATE = 10000;      // 100%
uint256 constant MAX_CASH_OUT_TAX_RATE = 10000;  // 100%
uint256 constant MAX_FEE = 250;                   // 2.5%

// Split percent precision
uint256 constant SPLITS_TOTAL_PERCENT = 1_000_000_000;  // 100%

---

Example Workflows

Create Project with Buyback Hook

1. Deploy JBBuybackHook for your token
2. Call launchProjectFor() with ruleset metadata:
   • useDataHookForPay: true
   • dataHook: buybackHookAddress
3. Payments automatically route through Uniswap when beneficial

Deploy a Revnet

1. Choose deployer (Basic, PayHook, Tiered721, Croptop)
2. Configure stages, premint, boost parameters
3. Call deployFor() with configuration
4. Revnet operates autonomously

Enable Cross-Chain

1. Deploy project on both chains with same ID
2. Deploy sucker pair via JBSuckerRegistry
3. Enable 100% cash out rate and owner minting
4. Users can prepare() on one chain, claim() on other
