From 12adb75b47bfd9c8a0ed784192aaeae1e9c5b438 Mon Sep 17 00:00:00 2001 From: Kapten boneng Date: Fri, 8 Nov 2024 11:16:11 +0700 Subject: [PATCH] Create Kontrak PiStable dengan Mekanisme Pegging Dinamis dan Stabilisasi Otomatis Penjelasan Kode Lanjutan Orakel Harga Pi Coin: Menggunakan AggregatorV3Interface dari Chainlink untuk mengambil data harga Pi Coin secara real-time. Ini memastikan nilai stablecoin mengikuti perubahan harga yang akurat. Rebalancing Otomatis: Fungsi rebalance secara otomatis menyesuaikan jumlah token beredar berdasarkan perbedaan antara harga target (peg) dan harga pasar saat ini. Ini memungkinkan stabilitas harga dengan menambah atau mengurangi supply sesuai kondisi pasar. Sistem Tata Kelola yang Lebih Kompleks: Fitur tata kelola dengan peran khusus (GOVERNANCE_ROLE) memungkinkan hanya anggota tertentu yang dapat mengubah pengaturan penting seperti targetPrice atau menjalankan proposal. Ini memberikan keamanan ekstra dan perlindungan terhadap penyalahgunaan. Proteksi Interval Rebalance: Rebalancing hanya dapat dilakukan setiap rebalanceInterval (misalnya, setiap 24 jam) untuk menghindari manipulasi atau tindakan tidak sah dalam mengubah nilai stablecoin. Minting dan Burning yang Dikontrol: Hanya anggota tata kelola yang dapat melakukan mint atau burn stablecoin untuk memastikan stabilitas supply dan mencegah inflasi atau deflasi yang tidak terkendali. Langkah Berikutnya Tes Stress dan Simulasi Pasar: Lakukan tes ketahanan dan simulasi di berbagai kondisi pasar untuk memastikan kontrak stabil dalam skenario harga yang ekstrem. Penguatan Keamanan Tambahan: Melakukan audit keamanan oleh pihak ketiga sangat disarankan sebelum deploy untuk mendeteksi potensi kelemahan dalam kode. Kontrak ini menyediakan infrastruktur yang lebih maju untuk Pi-Stabil-Revoluter-Inti dengan mekanisme stabilisasi otomatis, tata kelola, dan kompatibilitas lintas rantai. --- ...e Pegging Dinamis dan Stabilisasi Otomatis | 139 ++++++++++++++++++ 1 file changed, 139 insertions(+) create mode 100644 Kontrak PiStable dengan Mekanisme Pegging Dinamis dan Stabilisasi Otomatis diff --git a/Kontrak PiStable dengan Mekanisme Pegging Dinamis dan Stabilisasi Otomatis b/Kontrak PiStable dengan Mekanisme Pegging Dinamis dan Stabilisasi Otomatis new file mode 100644 index 0000000..f544e08 --- /dev/null +++ b/Kontrak PiStable dengan Mekanisme Pegging Dinamis dan Stabilisasi Otomatis @@ -0,0 +1,139 @@ +// SPDX-License-Identifier: MIT +pragma solidity ^0.8.0;
