Fee Structure

// User sends 100 ETH to buy tokens
const userSends = 100;

// Calculate 1% protocol fee
const totalFee = userSends * 0.01; // 1 ETH

// Split fee
const creatorFee = totalFee * 0.3; // 0.3 ETH (30%)
const platformFee = totalFee * 0.7; // 0.7 ETH (70%)

// Net to curve for trading
const netAmount = userSends - totalFee; // 99 ETH

// Calculate tokens from curve
const tokensOut = calculateBuyReturn(99);

// Update state
accumulatedCreatorFees += creatorFee; // 0.3 ETH saved for creator
transferToPlatform(platformFee); // 0.7 ETH sent immediately
transferToUser(tokensOut); // Tokens to buyer

// User sells 10,000,000 tokens
const tokensSold = 10_000_000;

// Calculate gross native out (before fees)
const grossNative = calculateSellReturn(tokensSold); // 5 ETH

// Calculate 1% fee on gross
const totalFee = grossNative * 0.01; // 0.05 ETH

// Split fee
const creatorFee = totalFee * 0.3; // 0.015 ETH (30%)
const platformFee = totalFee * 0.7; // 0.035 ETH (70%)

// Net to user
const userReceives = grossNative - totalFee; // 4.95 ETH

// Update state
accumulatedCreatorFees += creatorFee; // 0.015 ETH saved
transferToPlatform(platformFee); // 0.035 ETH sent
transferToUser(userReceives); // 4.95 ETH to seller

// Token bonded with 114.35 ETH liquidity (determined by k)
const bondingLiquidity = 114.35;
const reservedTokens = 150_000_000;

// Calculate 12% migration fee
const migrationFee = bondingLiquidity * 0.12; // 13.72 ETH

// Split fee
const creatorFee = migrationFee * 0.6; // 8.23 ETH (60%)
const platformFee = migrationFee * 0.4; // 5.49 ETH (40%)

// Net liquidity to DEX
const liquidityToDEX = bondingLiquidity - migrationFee; // 100.63 ETH

// Execute migration
