Chain Helpers

// All supported chains, keyed by chainId
const chains = await dzap.getAllSupportedChains();

// Same data, but cached across calls (static method, no args)
const cachedChains = await DZapClient.getChainConfig();

// Router/DCA/zap contract address for one chain + service (async)
const router = await dzap.getDZapContractAddress({ chainId: 8453, service: 'trade' });
