Building decentralized applications on the OKT Chain (OKTC) requires robust tools, and the Go SDK is one of the most powerful resources available for developers. Designed with simplicity and efficiency in mind, this SDK enables seamless interaction with the OKTC blockchain using the Go programming language. Whether you're managing accounts, issuing tokens, staking assets, or integrating decentralized exchange (DEX) functionalities, the OKTC Go SDK provides a comprehensive set of modules to streamline your development workflow.
This guide dives deep into the core capabilities of the OKTC Go SDK, covering essential functions across multiple modules such as Auth, Token, Staking, DEX, AMM Swap, Farming, Governance, and more. We'll explore how to use these tools effectively while maintaining security and performance.
Core Modules and Functionalities
The OKTC Go SDK is structured into modular packages, each dedicated to a specific blockchain function. Below is a breakdown of key modules and their practical applications.
Utilities: Account and Token Management
Located under exchain-go-sdk/utils, the utility package offers foundational functions for managing cryptographic identities and token operations.
Generate Secure Keys and Mnemonics
You can create secure wallet credentials programmatically:
- Random key generation: Use account name and password to generate a new key pair.
- Mnemonic-based keys: Derive private keys from BIP39-compliant seed phrases.
- Private key import: Import existing keys securely using encrypted storage.
Additionally, the SDK allows you to generate random mnemonics or derive private keys from them—ideal for non-custodial wallet integrations.
Multi-Send Token Parsing
For batch transactions, use ParseMultiSend to convert formatted strings like "addr1 1okt\naddr2 2okt" into structured TransferUnit objects, enabling efficient bulk transfers.

Querying Blockchain Data
Access real-time data across various domains using query interfaces provided by the SDK.
Authentication Module
Retrieve account details by address (in Bech32 format), including sequence numbers and account numbers—critical for constructing valid transactions.
Token Module
Query token metadata by symbol or owner address. This helps verify token legitimacy and track custom token deployments on-chain.
Staking Module
Obtain validator sets, individual validator details, and delegation status. These queries are essential for building staking dashboards or monitoring node performance.
DEX and Market Data
Using the Backend module:
- Fetch candlestick data for technical analysis.
- Retrieve recent trades, tickers, open/closed orders, and transaction history by account or product.
- Analyze order books via depth queries for real-time market insights.
Executing Transactions
Beyond reading data, the SDK supports full transaction lifecycle management.
Token Operations
With the Token module, developers can:
- Transfer OKT or custom tokens.
- Execute multi-receiver sends.
- Issue new fungible tokens with configurable supply and minting rights.
- Modify token metadata or adjust supply through minting/burning.
Each operation requires standard parameters: sender info, password, account/sequence numbers (for replay protection), and transaction memo.
Staking and Delegation
Validators and delegators can:
- Register or edit validator profiles.
- Deposit or withdraw staked tokens.
- Rebalance stakes across validators.
- Manage proxy delegation identities.
These features empower developers to build staking platforms with full control over node operations.
Governance Participation
Through the Governance module, users can:
- Submit proposals (text, parameter changes, token delisting).
- Increase deposit amounts to activate voting periods.
- Vote on active proposals using flexible options: yes, no, no_with_veto, or abstain.
This fosters community-driven upgrades and network governance automation.
Decentralized Exchange (DEX) Integration
The DEX module enables full trading functionality within your application.
Listing and Managing Trading Pairs
Operators can:
- Register or edit DEX operators with fee collection addresses.
- List new trading pairs with initial pricing.
- Deposit/withdraw liquidity (OKT) into listed products.
- Transfer ownership of trading pairs securely.
Ownership transfer requires confirmation by the recipient, ensuring secure handovers.

Automated Market Making (AMM Swap)
Leverage AMM-based liquidity pools for seamless token swaps.
Liquidity Management
Developers can:
- Create new swap pairs between any two tokens.
- Add or remove liquidity with slippage controls via min/max thresholds.
- Set deadlines to prevent stale transactions.
Token Swaps
Execute instant trades with guaranteed minimum output:
- Specify amount to sell and minimum expected return.
- Define recipient address and execution timeout.
This ensures user protection against volatility during high-latency conditions.
Yield Farming and Incentives
The Farm module supports incentive-based participation through liquidity mining.
Pool Management
Admins can:
- Create farm pools requiring minimum lock amounts.
- Fund pools with yield tokens distributed per block.
- Destroy pools when incentives conclude.
User Participation
Users can:
- Lock tokens in active pools.
- Unlock holdings and claim accrued rewards at any time.
- Check personal and global farming statistics.
This creates a complete ecosystem for incentivizing long-term token holding.
Network-Level Tools
Tendermint Integration
Direct access to consensus-layer data via Tendermint RPC equivalents:
- Fetch block details by height.
- Retrieve transaction receipts by hash.
- Query validator sets at specific blocks.
- Search transactions using event-based filters (e.g.,
message.action=send).
These tools are invaluable for block explorers, audit systems, and compliance monitoring.
Frequently Asked Questions (FAQ)
Q: Where can I find the source code for the OKTC Go SDK?
A: The SDK is open-source and hosted on GitHub. You can access it at official repositories for review and contribution.
Q: Can I use the SDK to build a non-custodial wallet?
A: Yes. The SDK supports mnemonic-based key derivation, offline signing (planned), and secure credential management—perfect for self-custody applications.
Q: Is there support for testnet environments?
A: Absolutely. The SDK works seamlessly on both mainnet and testnet chains. Always verify chain IDs and endpoints when switching environments.
Q: How do I handle transaction sequencing to avoid failures?
A: Always query the latest account number and sequence before broadcasting. Reuse leads to "invalid sequence" errors; increment properly after each transaction.
Q: Can I automate governance voting with this SDK?
A: Yes. The Governance module allows programmatic proposal submission and voting—ideal for DAO tooling or stake-weighted decision engines.
Q: What security practices should I follow when using the SDK?
A: Never hardcode passwords or private keys. Use environment variables or secure vaults. Validate inputs rigorously and sanitize all user-provided data.
