Overview

The Exchange Services provides a unified interface for cross-chain cryptocurrency exchange operations, supporting both EVM-compatible and Solana blockchains. Included services:

evmExchange: Handles exchanges on Ethereum, BSC, Polygon, Arbitrum, Optimism, and Avalanche
solExchange: Handles exchanges on Solana blockchain

EVM Exchange

Get Price Quote (Native → Token)

const price = await monei.evmExchange.getNativeToTokenPrice({
  tokenAddress: '0xTokenAddress',
  amount: '0.1',
  chainId: 56,
});

console.log(price.expectedOutput, price.priceImpact);

Swap Native → Token

const tx = await monei.evmExchange.swapNativeToToken({
  tokenAddress: '0xTokenAddress',
  amount: '0.1',
  chainId: 56,
  slippage: 0.5, // 0.5%
});

console.log(tx.txHash);

Get Price Quote (Token → Token)

const price = await monei.evmExchange.getTokenToTokenPrice({
  tokenIn: '0xTokenInAddress',
  tokenOut: '0xTokenOutAddress',
  amount: '100',
  chainId: 137,
});

console.log(price.expectedOutput, price.priceImpact);

Swap Token → Token

const tx = await monei.evmExchange.swapTokenToToken({
  tokenIn: '0xTokenInAddress',
  tokenOut: '0xTokenOutAddress',
  amount: '100',
  chainId: 137,
  slippage: 1,
});

console.log(tx.txHash);

Get Price Quote (Token → Native)

const price = await monei.evmExchange.getTokenToNativePrice({
  tokenAddress: '0xTokenAddress',
  amount: '0.1',
  chainId: 56,
});

console.log(price.expectedOutput, price.priceImpact);

Swap Token → Native

const tx = await monei.evmExchange.swapTokenToNative({
  tokenAddress: '0xTokenAddress',
  amount: '100',
  chainId: 56,
  slippage: 0.5,
});

console.log(tx.txHash);

Solana Exchange

Get SOL → Token Quote

const quote = await monei.solExchange.getSolToTokenQuote({
  outputMint: 'EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v', // USDC
  amount: '1',
  network: SolanaNetwork.MAINNET,
});

console.log(quote.expectedOutput, quote.priceImpact);

Swap SOL → Token

const result = await monei.solExchange.swapSolToToken({
  outputMint: 'EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v',
  amount: '1',
  slippage: 1,
  network: SolanaNetwork.MAINNET,
});

console.log(result.signature);

Get Token → Token Quote

const quote = await monei.solExchange.getTokenToTokenQuote({
  inputMint: 'TokenAMintAddress',
  outputMint: 'EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v', // USDC
  amount: '1',
  network: SolanaNetwork.MAINNET,
});

console.log(quote.expectedOutput, quote.priceImpact);

Swap Token → Token (Solana)

const result = await monei.solExchange.swapTokenToToken({
  inputMint: 'TokenAMintAddress',
  outputMint: 'TokenBMintAddress',
  amount: '100',
  slippage: 1,
  network: SolanaNetwork.MAINNET,
});

console.log(result.signature);

Get Token → SOL Quote

const quote = await monei.solExchange.getTokenToSolQuote({
  inputMint: 'EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v', // USDC
  amount: '1',
  network: SolanaNetwork.MAINNET,
});

console.log(quote.expectedOutput, quote.priceImpact);

Swap Token → SOL

const result = await monei.solExchange.swapTokenToSol({
  inputMint: 'EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v',
  amount: '50',
  slippage: 1,
  network: SolanaNetwork.MAINNET,
});

console.log(result.signature);

Working with Response Objects

All methods return objects with property access:

// Price quote response
const quote = await monei.evmExchange.getNativeToTokenPrice({...});
console.log(quote.expectedOutput);  // Expected output amount
console.log(quote.priceImpact);      // Price impact percentage
console.log(quote.route);            // Swap route details

// Transaction response
const tx = await monei.evmExchange.swapNativeToToken({...});
console.log(tx.txHash);      // Transaction hash
console.log(tx.status);       // Transaction status
console.log(tx.explorerUrl);  // Block explorer URL

// Solana swap response
const result = await monei.solExchange.swapSolToToken({...});
console.log(result.signature);  // Transaction signature
console.log(result.blockhash);  // Block hash

Notes

All methods require a properly configured MoneiClient instance with authentication
EVM methods require chainId parameter (e.g., 56 for BSC, 137 for Polygon)
Solana methods require network parameter (SolanaNetwork.MAINNET or SolanaNetwork.DEVNET)
slippage is optional (defaults to 0.5% for EVM, 1% for Solana)
All responses are strongly typed objects with property access
