A **smart contract** is a contract that self-executes according to the terms of the agreement between the buyer and the seller that are written directly into lines of code. The code and the agreements it contains exist on a distributed and decentralized blockchain network. Code controls execution, and transactions are traceable and irreversible. Smart contracts enable transactions and agreements of trust between disparate and anonymous parties without the need for a central authority, legal system or external enforcement mechanism. Although blockchain technology is considered the foundation of bitcoin, it has evolved far beyond cryptoassets. 👉 **For more information, you can consult [this article written by our experts](https://www.coinhouse.com/insights/ethereum-en-en/smart-contract) which explains what a smart contract is in detail.** If you have any further questions, we are at your disposal ! *Monday to Friday : from 9:30 to 12:30 and 13:30 to 18:00.* [Write us here](https://3u6rv.share.hsforms.com/2h5nTGUfPQSOEeI3emKiSLw) **Contact us by phone 👉 +33 1 82 88 29 51** - [Create an account](https://support.coinhouse.com/en/create-an-account?hsLang=en) - [The basics](https://support.coinhouse.com/en/the-basics?hsLang=en) - [Buying, selling and swapping](https://support.coinhouse.com/en/buying-selling-and-swapping?hsLang=en) - [Payment method](https://support.coinhouse.com/en/payment-method?hsLang=en) - [My account security](https://support.coinhouse.com/en/my-account-security?hsLang=en) - [Our products](https://support.coinhouse.com/en/our-products?hsLang=en) - [Withdrawal and deposit of cryptocyurrencies](https://support.coinhouse.com/en/withdrawal-and-deposit-of-cryptocyurrencies?hsLang=en) - [What's New ⚡](https://support.coinhouse.com/en/whats-new?hsLang=en) - [Other](https://support.coinhouse.com/en/other?hsLang=en) - [Account modification](https://support.coinhouse.com/en/account-modification?hsLang=en) - [Account type & status](https://support.coinhouse.com/en/account-type-status?hsLang=en) - [Taxation](https://support.coinhouse.com/en/taxation?hsLang=en) - [Vigilance against fraud](https://support.coinhouse.com/en/vigilance-against-fraud?hsLang=en) - [Ledger](https://support.coinhouse.com/en/ledger?hsLang=en) - [Inaccessible account](https://support.coinhouse.com/en/inaccessible-account?hsLang=en) - [Regulatory and operational developments](https://support.coinhouse.com/en/regulatory-and-operational-developments?hsLang=en) Copyright © 2026, Coinhouse ![Coinhouse](https://support.coinhouse.com/hubfs/ch-logo-blanc.svg) The leading French platform for investing in crypto-assets. #### Useful links - [Coinhouse website](https://www.coinhouse.com) - [Contact support](https://3u6rv.share.hsforms.com/2h5nTGUfPQSOEeI3emKiSLw) - [support@coinhouse.com](mailto:support@coinhouse.com) #### Follow us ##### Coinhouse Coinhouse · SASU with share capital of €210,000 · Registered with the Paris Trade and Companies Register (RCS) under number 815 254 545 · Registered office: 14 Avenue de l'Opéra, 75001 Paris.
