Testnet → Mainnet Migration Guide

Three config changes are required:

// Testnet
const service = new SorobanSubscriptionService({
  sorobanUrl: "https://soroban-rpc.stellar.org/testnet",
  networkPassphrase: Networks.TESTNET,
});
await service.createSubscription({
  contractId: "CAH3T7NSZMZTX2KPKK5IKKMCKE4ZDYVK4OO64OISB6OY7W3OLS6OJJMP",
  // ...
});

// Mainnet
const service = new SorobanSubscriptionService({
  sorobanUrl: "https://soroban-rpc.stellar.org",
  // networkPassphrase defaults to Networks.PUBLIC in v1.0.0
});
await service.createSubscription({
  contractId: "CC76NWELMDVXHFU7T62KJQ2UI6EPHPVG25C65EIIP7R6CPEFITTDZXPA",
  // ...
});
