@moon-x/tron-adapter

Chain-aware Tron signing for MoonX ephemeral signers (agents). Wraps the low-level signWithEphemeralSigner primitive with intent-level helpers so integrators never hash anything by hand:

• signMessage(message) - TIP-191 message signature (TronWeb signMessageV2 semantics), verifiable with Trx.verifyMessageV2.
• signTransaction(tx) - signs a TronWeb-built transaction (sha256 of raw_data_hex) and returns the broadcast-ready object for tronWeb.trx.sendRawTransaction.

Build transactions with TronWeb's TransactionBuilder; this package signs them. It has no TronWeb runtime dependency - transactions arrive already protobuf-serialized (raw_data_hex), and the signature is appended exactly the way TronWeb's own trx.sign() would.

Usage

import { createTronSigner } from "@moon-x/tron-adapter";

const signer = createTronSigner({
  apiPubHex,   // agent keypair from provisioning
  apiPrivHex,
  walletId,    // Tron (secp256k1) wallet the agent is provisioned for
  secretKey,   // moon_sk_* - server-only
});

const signature = await signer.signMessage("gm");
const signedTx = await signer.signTransaction(unsignedTx); // from TransactionBuilder

For a custom transport (tests, iframe MPC), construct MoonXTronSigner with your own EcdsaSignFn instead of a config.
