Token Smart Contract Audit
Use our extensive audits to discover vulnerabilities in your token’s smart contract and make it safer to deploy on the blockchain.
Crypto Token Projects Audited By Us
A significant portion of our large portfolio is constituted by our valued clients who trusted us to effectively and comprehensively audit their crypto token projects.
Why are Token Audits Necessary?
An audit is an investment in any project's long-term success and sustainability.
Regular smart contract audits are necessary for crypto tokens to ensure:
Security Assurance
Audits identify and rectify security flaws that are not discovered during the development stage. An effective audit ensures that the token operates as intended and remains protected from potential attacks.
Building Trust
Trust is crucial in the cryptocurrency space. A token with a well-audited smart contract demonstrates a commitment to security and transparency. Investors and users are likelier to engage with a token that has undergone a thorough audit by a reputable firm, fostering trust in the project.
Compliance and Regulation
Ensuring that a token's smart contract complies with legal requirements is vital. Audits can identify areas where a contract might fall short of regulatory standards, allowing the project team to make necessary adjustments to adhere to legal guidelines.
Token Standards We Audit
Our experienced token smart contract auditors are adept at auditing any token standard belonging to the EVM-compatible blockchains.
Some of the popular token standards audited by us are the following:
ERC-20
A fungible (interchangeable) token standard developed for use on the Ethereum blockchain. These tokens are created, transferred, and managed using smart contracts on the Ethereum network.
Widely used for creating different types of cryptocurrencies, including security tokens, utility tokens, and stablecoins.
ERC-721
The non-fungible token (NFT) standard for the Ethereum blockchain, which represents ownership of a specific asset, like digital art, collectibles, gaming items, event tickets, or virtual real estate.
ERC-777
The improved and extended version of the ERC-20 standard with backward compatibility. It was created to make sending and receiving tokens more efficient by implementing the ‘Hooks’ function.
The feature of rejecting transactions from a blacklisted address was also introduced by this standard.
ERC-1155
The standard blended features of ERC-20 and ERC-721. With this standard, tokens can be either fungible or non-fungible.
The batch transfer functionality and ability to bundle multiple assets in one single smart contract make it cost-effective by significantly reducing gas fees.
BEP-20
A token standard created for BNB (BSC) Smart Chain. It comes with various features, such as blacklisting, minting, and pausing token burns.
It is based on the ERC-20 standard but was made suitable for the Binance ecosystem. Ideal for dApps and DEX on the BNB blockchain.
TRC-20
Fungible Token Standard for TRON blockchain. Similar to ERC-20 in contract design but are designed to just run on the TRON blockchain.
Checks Involved in Token Audit
Other than analyzing if a particular token adheres to its standard specifications, our expert auditors also inspect the token’s specific functionalities and features.
The auditing methods and checks may also vary based on the blockchain platform the token is built upon, in addition to the blockchain’s inherent vulnerabilities and limitations.
ERC-20 Tokens
Fungibility and Interoperability: Our auditors ensure that ERC-20 tokens can be easily traded on cryptocurrency exchanges and adhere to the ERC-20 standard’s specifications.
Standard functions: Our token smart contract audit covers checking standard functions like transfer, approve,and transferFrom to ensure they behave as expected. We also verify that the total supply is fixed and that tokens can be transferred correctly between addresses.
Arithmetic errors: ERC-20 tokens use a variety of arithmetic operations, such as addition, subtraction, and multiplication. We audit these operations to ensure that they are performed correctly.
Reentrancy attacks: Reentrancy attacks exploit vulnerabilities in smart contracts to allow an attacker to steal funds. ERC-20 tokens are particularly vulnerable to reentrancy attacks. Our auditors always check for these vulnerabilities.
Minting and burning: ERC-20 tokens can be minted and burned, which are processes that create and destroy tokens.
We audit these processes to ensure they are performed correctly and that attackers cannot exploit them.
ERC-721 Tokens
Ownership tracking: ERC-721 tokens track ownership of the tokens on the blockchain. Our audit makes sure that each token ID is distinct and its ownership is transferred correctly, and that tokens are protected and cannot be stolen.
Approvals: ERC-721 tokens allow owners to approve other users to spend their tokens. In our audit, we audit this functionality to ensure that approvals are handled correctly and that unauthorized users cannot spend tokens.
Token Metadata: ERC-721 tokens can store metadata such as the token name, description, and image on both—on-chain and off-chain. Our auditors validate the integrity of this data and ensure it corresponds accurately to the token and is stored and accessed correctly
ERC-1155 Tokens
Fungibility and Multi-Fungibility: Our auditors check if the contract correctly manages both fungible and non-fungible assets simultaneously.
Gas Efficiency: We do rigours audits to check the contract's gas usage and efficiency, ensuring it performs well even when dealing with a large number of different token types.
Batch Transfers: Our token auditors validate the batch transfer functionality and ensure it operates securely and accurately.
Other Token Standards
Network-Specific Features: Each blockchain may have specific features or limitations. Our auditors ensure that tokens comply with these network-specific requirements while focusing on aspects like fungibility, uniqueness, gas efficiency, interoperability, and adherence to the specific rules and functions defined by the standard.
