Understanding Non-Custodial Services
Non-custodial services are a type of service that does not involve the holding or control of funds or assets by a platform or third-party during a transaction or service period. Instead, these services rely on trustless smart contracts, which are intricate self-executing codes that power blockchain networks. This is in contrast to custodial services, where the platform takes possession of a user’s funds or assets for safekeeping and management. Non-custodial services are considered a key aspect of decentralization and eliminate the need for intermediaries. Crypto enthusiasts prefer non-custodial services due to their lower risks.
Custodial services come with various risks, including censorship, confiscation, downtime, insolvency, longer processing times, complexity, and counterparty risk. Examples of centralized services include popular exchanges like Binance and Coinbase, lending/borrowing platforms like BlockFi, stablecoins like Tether and Binance USD, and digital asset management services such as Grayscale and Paypal.
In contrast, non-custodial services offer trustless transactions, resistance to censorship, faster processing times, simplicity, confiscation resistance, and no risk of insolvency or downtime.
Examples of non-custodial services include decentralized exchanges (DEXes) like EtherDelta, Binance Dex, 1inch, and Uniswap, lending/borrowing platforms like Maker and Compound, stablecoins like DAI and Ampleforth, and digital asset management services like yearn.finance and Genesis Vision. Non-custodial wallet solutions like TrustWallet and hardware wallets such as Ledger Nano, Trezor, and CoolWallet provide users with complete ownership and control over their crypto assets through private keys or recovery seeds.
Custodial services currently have an advantage in terms of recovery and security, as reputable centralized services can assist users in case of theft or malicious activity, often with insurance coverage. Non-custodial services carry a risk related to smart contracts, where flawed or vulnerable code can be exploited for fund theft. Additionally, if users lose their private keys or access to their accounts, it is often challenging to recover their funds. Custodial services, on the other hand, have better recovery options available through identification methods since they control access to users’ funds.
The increasing implementation of anti-money laundering (AML) regulations, such as the FATF Travel Rule, targeting custodial crypto service providers, is also pushing users towards non-custodial solutions. These solutions allow users to maintain their anonymity, at least for the time being.
