Solidity ethereum compiler
This includes code review, testing, audits and correctness proofs. Also note that users are sometimes more confident in code than its authors. Finally, blockchains have their own things to watch out for, so please take a look at the section Security Considerations.
This documentation is translated into several languages by community volunteers, but the English version stands as a reference. On the next pages, we will first see a simple smart contract written in Solidity followed by the basics about blockchains and the Ethereum Virtual Machine. The next section will explain several features of Solidity by giving useful example contracts Remember that you can always try out the contracts in your browser!
If you still have questions, you can try searching or asking on the Ethereum Stackexchange site, or come to our gitter channel. Ideas for improving Solidity or this documentation are always welcome! Keyword Index , Search Page. This includes code review, testing, audits and correctness proofs.

After you found a way to install solc , you make sure it's in the path. This contract offers a unary method: You are ready to compile solidity code in the geth JS console using eth.
The compiler is also available via RPC and therefore via web3. The compiler output for one source will give you contract objects each representing a single contract. The actual return value of eth. Since our contract's name is test , eth.
The immediate structuring of the compiler output into code and info reflects the two very different paths of deployment. The compiled EVM code is sent off to the blockchain with a contract creation transaction while the rest info will ideally live on the decentralised cloud as publicly verifiable metadata complementing the code on the blockchain.
If your source contains multiple contracts, the output will contain an entry for each contact, the corresponding contract info object can be retrieved with the name of the contract as attribute name. You can try this by inspecting the most current GlobalRegistrar code:. Ethereum Frontier Guide Introduction 0.
