Custom deployments

The SDK resolves the correct contract from the chain ID automatically, so you normally don’t need the address. Pass it explicitly only for custom deployments: 
const client = new ConfidentialTransferClient(
  "https://sepolia.base.org",
  "0xYourCustomStabletrustContract",
  84532,
);
On the Tempo network (chainId 42431), the SDK uploads ZK proofs to IPFS instead of passing them as calldata and the chain uses token-based fees. Both are handled automatically, so no code change is required.
