Secure Logic

Audited STO Smart Contracts

Immutable code for regulated assets. We develop and audit ERC-1400 and ERC-3643 complaint smart contracts that enforce compliance on-chain.

Audit Code

Token Standards

Security tokens require specialized standards to handle complex logic like whitelist management, forced transfers (for legal recovery), and dividend distribution.

ERC-1400

The 'Security Token Standard' with partial fungibility and document management.

ERC-3643 (T-Rex)

Permissioned token standard ensuring only eligible wallets can hold tokens.

Polymath

A suite of modules for KYC, locking, and voting logic.

contract SecurityToken is ERC1400 {

mapping(address => bool) public isWhitelisted;

// Enforce transfer restrictions

function transfer(...) public override {

require(isWhitelisted[to], "Recipient not KYC verified");

super.transfer(to, amount);

}

}

Smart Capabilities

On-Chain Compliance

Automated checks for KYC status, investor limits, and jurisdictional restrictions before every transfer.

Clawback Mechanism

Allows administrators to recover tokens in case of loss of keys or court orders, a legal requirement for securities.

Dividend Distribution

Efficiently distribute stablecoin dividends to thousands of token holders in a single transaction.

Security Lifecycle

Zero margin for error.

Unit Testing

100% code coverage for all functions.

Static Analysis

Automated scanning for known vulnerabilities.

Formal Verification

Mathematical proof of contract correctness.

3rd Party Audit

External review by top firms (CertiK, Hacken).

Technical FAQ

From logic to launch.

Yes, we typically use Proxy patterns (like EIP-1967) to allow for logic upgrades while preserving the state (balances) and address of the token.

Unlike crypto, securities must be recoverable. We implement 'force transfer' functions accessible only by a multi-sig governance wallet to restore access.

The smart contract includes a 'pause' functionality that can freeze all transfers or specific accounts in compliance with regulatory orders.
