From 944291934eb5ef9a96c45cc9f779e7c4d8d436d1 Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 2 Apr 2026 00:59:18 +0100 Subject: [PATCH] feat(asset): add RPC client + CLI for confidential assets (HF5) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit rpc/assets.go: DeployAsset, EmitAsset, BurnAsset, GetAssetInfo daemon/server.go: get_asset_info RPC method (native LTHN + custom assets) cmd_deploy_itns.go: CLI command to deploy ITNS trust token cmd/core-chain: register asset command group Ready for HF5 activation — `core-chain asset deploy-itns` deploys the ITNS token via the wallet RPC.
