Talken API

Talken API is the core infrastructure that powers all Talken services. Features like Talken Wallet, Swap, and Staking operate through this API, and partners can use the same API to integrate Talken’s blockchain capabilities into their own services.

​

Swap and Cross-Chain

All Talken Swap capabilities — multi-DEX quote comparison, optimal route finding, and cross-chain bridging — are available through the API. From same-chain token exchanges to cross-chain stablecoin transfers, everything can be handled with a single API.

​

Wallet Management

MPC-based wallet creation, recovery, and address management are accessible via the API. Multi-chain wallets covering EVM, Solana, Bitcoin, and TRON are managed under a single account, and transaction signing and submission are also handled through the API.

​

Gasless Execution

The API supports gasless transactions where users don’t need to pay gas fees directly. A relayer pays the gas fee on behalf of the user, and the user pays a service fee in USDT, USDC, or TALK. Partners can use this feature to let users access their services without holding native tokens. Gas sponsoring via ERC-4337 Paymaster is also supported. Partners can cover gas fees on behalf of their users, providing a completely free transaction experience.

​

Staking

Staking for TALK, ETH (Lido), and KAIA (Kommune) is available through the API. It supports querying staking positions, checking rewards, and building stake/unstake transactions.

​

Multi-Chain Support

Talken API supports the following blockchains:

• EVM: Ethereum, Arbitrum, Base, Polygon, BNB Chain, Kaia, HyperEVM
• Solana: Mainnet and testnet
• Bitcoin: Mainnet and testnet
• TRON: Mainnet and testnet

​

Data and Analytics

Token lists, price data, balance queries, and transaction history can all be retrieved via the API. Balances across multiple chains can be checked in a single call, making it useful for portfolio management and dashboard development. Analytics data including trade volume statistics, per-network breakdowns, DEX/pool stats, and bridge usage metrics are also available. The Explorer API allows searching transactions and tracking the progress of cross-chain transfers.

​

Authentication and Security

The API provides authentication based on email and social login (Google, Apple, Kakao, Naver, Line). It operates on JWT tokens, and through MPC technology, private keys never exist in a single form on any server or client.

​

Partner Integration

Partners can integrate the following capabilities into their services through Talken API:

• User wallet creation and management
• Token swaps and cross-chain transfers
• Gasless transaction execution
• Staking service integration
• Token balance and NFT queries

​

Relationship with Talken Kit

Partners who need a frontend wallet connection screen can use Talken Kit to implement wallet login and transaction signing without direct API integration. Talken Kit is a frontend SDK built on top of Talken API.
