Indodax

Indodax (Indonesia Digital Asset Exchange) is the oldest and largest cryptocurrency exchange in Indonesia, offering spot trading for more than 500 digital assets paired against the Indonesian Rupiah (IDR). Founded in February 2014 as Bitcoin.co.id — one of Southeast Asia's earliest crypto trading venues — the platform rebranded to Indodax in March 2018 to reflect its expansion beyond Bitcoin. As of mid-2026, the exchange reports over 10.1 million registered members and processes an average of 10 trillion IDR in monthly transaction volume.

Founding and History

Indodax was co-founded by Oscar Darmawan and William Sutanto, two technologists who had previously collaborated at PT Bumi Intermedia, an Indonesian IT consulting firm, and had co-operated ads-id.com, an early Indonesian internet forum. They launched Bitcoin.co.id in February 2014, initially focused exclusively on BTC-to-IDR trading. The platform was built to solve a specific gap: there was no regulated, domestically operated venue where Indonesians could buy and sell cryptocurrency against their national currency.

East Ventures, the prominent Southeast Asia-focused venture firm, led a seed round in November 2017. Das Capital Group also invested. The rebranding to Indodax followed in March 2018 as the asset listing expanded well beyond Bitcoin.

In May 2025, Oscar Darmawan transitioned from CEO to Chairman, with co-founder William Sutanto assuming the CEO role. Indodax is headquartered in Jakarta at Millennium Centennial Center, South Jakarta.

How It Works

Indodax operates as a centralized limit-order-book exchange where users deposit IDR or supported crypto assets and place spot buy or sell orders. Deposits of IDR can be made through Indonesian bank transfer, virtual accounts, and e-wallets. The exchange matches buy and sell orders in real time and settles trades against IDR balances, eliminating the need to use USDT or other stablecoins as an intermediate step — a significant convenience for Indonesian retail users.

The platform offers a web interface and mobile applications on Android and iOS. It supports market orders, limit orders, and stop orders across its full list of trading pairs. Users can monitor charts, manage portfolios, and configure price alerts through the same interface.

Trading fees follow a maker-taker model with separate rates for IDR and USDT denominated markets. IDR market trades carry a 0.1% maker fee and 0.2% taker fee. USDT market trades are priced significantly lower at 0.03% maker and 0.06% taker, providing an economic incentive for experienced traders who denominate in stablecoins. The minimum trade size is Rp10,000 — keeping the entry point accessible for first-time investors. Withdrawals to Indonesian bank accounts carry a flat Rp10,000 processing fee with a Rp100,000 minimum withdrawal amount.

Assets and Trading Pairs

Indodax lists more than 500 crypto assets, all paired against the Indonesian Rupiah. This includes major assets (Bitcoin, Ethereum, BNB, Solana, XRP), stablecoins, and a wide range of altcoins including Solana ecosystem tokens. The broad listing reflects Indodax's strategy of serving Indonesian retail demand across token categories, including meme coins. In a July 2026 update, the exchange announced delistings of lower-liquidity assets including XGD, ALIF, TOKO, DCT, GLCH, LABUBU, SLERFV2, RDNT, HIFI, BOND, and SRM, indicating ongoing curation of the asset list.

Solana Ecosystem Connection

In April 2026, Indodax expanded into tokenized financial assets by launching seven tokenized global stocks issued on the Solana blockchain. The assets — representing shares in Tesla, Alphabet (Google), NVIDIA, Apple, Amazon, Coinbase, and Circle — became available for deposit starting April 9, 2026, with trading opening April 16, 2026. Each token maintains a 1:1 value correlation with the underlying share and enables fractional ownership, 24/7 trading, and near-real-time settlement. Indodax cited Solana's transaction throughput and low fees as the rationale for building this product on the Solana network. This made Indodax one of the first Indonesian retail exchange platforms to issue regulated tokenized equities on a public blockchain.

Regulatory Status

Indodax is fully licensed and supervised under Indonesian law. It holds a PAKD license (Digital Financial Asset Trader) issued by OJK (Otoritas Jasa Keuangan, Indonesia's Financial Services Authority), which assumed oversight of the country's crypto sector on January 10, 2025 under Law No. 4 of 2023 (UU P2SK), transferring authority from BAPPEBTI. The OJK license is numbered S-18/D.07/2025. Indodax also holds a Physical Crypto Asset Trader (PFAK) license from Bappebti under number 10/BAPPEBTI/PFAK/12/2024, and is registered with CFX (Crypto Futures Exchange) and KOMDIGI (Ministry of Communication and Digital Affairs). The exchange holds ISO-9001 and ISO-27001 certifications from BSI Group, covering quality management and information security respectively.

Customer asset custody is handled by PT Kustodian Koin Indonesia (Indonesia Coin Custodian), an independent custodian that holds crypto assets separately from exchange operational funds. Indodax publishes Proof of Reserves data tracked via Arkham Intelligence, providing public on-chain transparency over its holdings.

This regulatory profile is significant in the Indonesian market, where unlicensed exchanges face barriers to operating legally, and gives Indodax structural advantages when competing with international platforms for domestic retail customers.

September 2024 Security Incident

On the evening of September 10, 2024, Indodax suffered a major security breach. Blockchain security firm Cyvers identified over 150 suspicious on-chain transactions targeting the exchange's hot wallets across multiple blockchains. Approximately $20.5 to $22 million in crypto assets were stolen, including USDT, ETH, BTC, MATIC, ARB, ENA, and SHIB. The attacker converted stolen assets to ETH in rapid succession to hinder tracking and freezes.

Cyvers and other analysts noted strong behavioral similarities to attacks attributed to Lazarus Group, the North Korean state-sponsored hacking collective known for large-scale theft from centralized exchanges. Indodax took its web and mobile platforms offline following detection, halted all withdrawals, and migrated remaining hot wallet funds to cold storage while conducting an investigation. BAPPEBTI, which still held regulatory authority at the time, issued a public statement advising investors to remain calm. No significant public recovery of the stolen assets has been reported.

Academy and User Education

Indodax operates Indodax Academy, an educational content channel providing learning materials on crypto trading, blockchain fundamentals, and market analysis. The academy publishes articles and guides in Indonesian, targeted at onboarding first-time investors to crypto markets. This positions Indodax not only as a trading venue but as an entry point for crypto education in the Indonesian market, where English-language resources can be a barrier to adoption.

Market Position

Indodax's claim to being Indonesia's first and largest exchange is backed by its founding date, member count, and regulatory completeness. With over 10 million monthly visitors, 10+ million registered accounts, and average monthly IDR volume exceeding 10 trillion IDR, it functions as the primary gateway for Indonesian retail participation in crypto markets. Its combination of domestic licensing, IDR trading pairs, local-language support, and integration with Indonesian banking infrastructure gives it a differentiated position relative to international exchanges like Binance, which also operates in Indonesia but through a separate licensed subsidiary (TokoCrypto).
