Usage Example

// Validate chain before deposit
async function validateChain(chainId: number): Promise<boolean> {
  const response = await fetch('https://api.stableyard.fi/sdk/v1/supported-chains');
  const { data } = await response.json();

  const chain = data.chains.find(c => c.chainId === chainId);
  return chain?.isActive ?? false;
}

// Get USDC address for a chain
async function getUsdcAddress(chainId: number): Promise<string | null> {
  const response = await fetch('https://api.stableyard.fi/sdk/v1/supported-chains');
  const { data } = await response.json();

  const chain = data.chains.find(c => c.chainId === chainId);
  const usdc = chain?.tokens.find(t => t.symbol === 'USDC');
  return usdc?.address ?? null;
}
