Thailand Tightens Oversight on Non-Custodial Crypto Wallets

Non-custodial crypto wallets in Thailand will come under stricter control: the local Securities and Exchange Commission has approved new rules for digital asset transactions. Crypto services will be required to collect information about the senders and recipients of transfers, as well as confirm that the cryptocurrency wallet used actually belongs to the declared owner.

What Will Change for Crypto Services

The new requirements will take effect on February 27, 2027. From that day, platforms dealing with digital assets must accompany each transaction with data about the parties involved and retain this information for at least five years.

Upon request from authorities, such information will need to be provided to regulators. This applies to operations that use blockchain and software for self-custody of digital assets, including popular wallet solutions like MetaMask.

Why the Regulator is Introducing New Rules

The Secretary-General of the Thai Securities and Exchange Commission, Pornanong Budsaratrakun, stated that the updated regulations aim to reduce the risk of using cryptocurrency platforms for money laundering and financing terrorism.

The regulator aims to align local rules with international standards set by the Financial Action Task Force (FATF). For users, this means stricter checks on transfers when cryptocurrency moves between services and personal wallets.

Context: Fighting Suspicious Accounts

Previously, Thai crypto platforms had already frozen over 10,000 accounts. Their owners were suspected of money laundering after authorities intensified the fight against so-called mule accounts, which can be used to legitimize criminal proceeds.

The new rules expand this approach: not only exchange accounts but also non-custodial wallets through which transfers occur will come under closer scrutiny. This is significant for a market where Bitcoin and other digital assets are increasingly used outside traditional custodial platforms.

What is a Non-Custodial Crypto Wallet

A non-custodial crypto wallet is one where the user stores their private keys or seed phrase themselves and confirms transactions independently. Such a wallet does not hold cryptocurrency within itself: assets remain on the blockchain, while the application or device helps sign transactions and manage addresses.

The main difference from a custodial wallet is who controls access to the funds. In a custodial model, the service, such as an exchange or payment platform, holds the keys. In a non-custodial model, the keys remain with the owner, giving them more control but also making them responsible for securing access.

Types of Non-Custodial Wallets and How Anonymity Works

Non-custodial wallets can be desktop, mobile, hardware, web wallets, or paper wallets. Desktop and mobile options operate through an application, web wallets are often opened in a browser, hardware wallets store keys on a separate device, and paper wallets involve offline storage of data for access.

Technically, it is possible to create an anonymous non-custodial wallet: generating an address usually does not require an account with a custodial service. However, anonymity does not equate to complete invisibility. Transactions on public blockchains can be tracked by addresses, and if an address is linked to an exchange, service, or personal data, the level of privacy significantly decreases.

How to Choose, Set Up, and Secure a Non-Custodial Wallet

When choosing a reliable non-custodial wallet, it is important to consider the reputation of the developers, support for necessary networks and tokens, regular updates, a clear backup process, and the ability to manage the seed phrase without sharing it with third parties. Among popular software solutions, MetaMask is often mentioned, while for long-term storage, users frequently opt for hardware wallets.

Basic setup usually looks like this: install the wallet from an official source, create a new address, write down the seed phrase offline, enable a password or biometric security, and first test the functionality with a small transfer. For security, the seed phrase should not be stored in the cloud, sent via messaging apps, or entered on suspicious websites. It is also important to update the application, carefully check the recipient's address, and not connect the wallet to unknown services.
