The Slingoor token is a standard ERC-20 implementation with additional custom logic for transfer restrictions. The audit identified critical flaws in the return value handling of transfer functions and insecure authorization patterns using tx.origin. While the core ERC-20 logic is standard, the custom transfer path introduces significant integration risks for decentralized exchanges and automated protocols.

How holder types affect the score
Share held by contracts — treasury, vesting, bridge or staking — is discounted against share held by wallets when the score is computed: a contract cannot decide to sell the way an anonymous holder can, though it can still be drained or voted to sell. Effective concentration is the figure the risk score is actually calculated from.

Security Findings
HighNon-Compliant Transfer Return Values
The _transfer, transfer, and transferFrom functions fail to correctly handle or return the expected boolean values required by the ERC-20 standard. This causes external contracts and automated market makers to incorrectly interpret the success or failure of token transfers.CD-01
Issue
The _transfer, transfer, and transferFrom functions fail to correctly handle or return the expected boolean values required by the ERC-20 standard. This causes external contracts and automated market makers to incorrectly interpret the success or failure of token transfers.
Fix
Ensure that all transfer functions explicitly return a boolean 'true' upon success and revert on failure, adhering strictly to the EIP-20 specification.
Status
Unresolved
MediumInsecure Authorization via tx.origin
The returnTx function uses tx.origin to determine authorization rules. This is a security vulnerability because an attacker can trick a user into interacting with a malicious contract, which then calls returnTx, allowing the attacker to bypass intended access controls.CD-02
Issue
The returnTx function uses tx.origin to determine authorization rules. This is a security vulnerability because an attacker can trick a user into interacting with a malicious contract, which then calls returnTx, allowing the attacker to bypass intended access controls.
Fix
Replace tx.origin with msg.sender to ensure that the immediate caller is the entity being authorized, which is the standard practice for secure smart contract development.

Analysis
AI Copilotas of audit · Nov 2The architecture follows a standard ERC-20 pattern but fails to adhere to the EIP-20 specification regarding return values. 7.1 Architecture is simple, yet 7.2 Code Security is compromised by improper boolean handling in _transfer. 7.3 Access Control is weakened by the reliance on tx.origin in the returnTx function, which is susceptible to phishing-based authorization bypasses. 7.6 External integrations will likely fail due to the non-compliant return behavior.
7.4 Economic and 7.5 Governance controls are not present as the contract lacks administrative functions or complex economic parameters. The token operates as a simple asset without inflationary or deflationary mechanisms. 7.8 Operations are straightforward, though the lack of emergency pause functionality limits recovery options.
7.7 Upgrades are not applicable as the contract is not a proxy and lacks upgradeability patterns. The code is immutable, meaning any identified vulnerabilities cannot be patched without deploying a new contract. This provides high transparency but zero flexibility for future security remediation.
The development team should immediately refactor the transfer logic to ensure all functions return the correct boolean values as expected by the ERC-20 standard.
Furthermore, replace all instances of tx.origin with msg.sender to prevent unauthorized access and potential phishing attacks. Following these changes, the contract should undergo a comprehensive re-audit. Integration with external protocols should be avoided until the return value discrepancy is resolved to prevent loss of funds in automated liquidity pools.
