LATOKEN exchange has 2 million accounts including 900k+ users of our Android app rated 4.4 by 25+ thousands of reviews. We leverage the next tech to make account opening as easy as Instagram. The technology and our Olympic sports culture can make us the first billion users digital wallet needed to free people to manage their financial life. For the past 3 years we have been developing our own blockchain (called “Lachain”) and we are now building the DeFi ecosystem based on it (including DEX, dApp, IDO, NFT etc). Here is our mainnet and GitHub. Today, is a great moment to join us as crypto is expanding into mainstream financial market and ex CFO of JP Morgan joined our advisory board and 2 presidents joined us in Davos. Here is our backlog. Role: Crosschain Developer Unit: LACHAIN Details: Story: Users want to trade, deposit, borrow, etc tokens from any blockchains on LACHAIN to get additional rewards in our DeFi ecosystem. Goal: Launch crosschain bridge with TRON, BCS, ETH, BTC, SOL blockchains by the end of Q4. Add 1 new blockchain to bridge monthly. How: Develop cryptographic protocols and integration service with different blockchains Build and implement architecture solutions to optimize gas costs. Solve algorithmic problems and find the best solutions to decrease swap time Write unit tests and documentation. Conditions: Code have tests and documentation coverage. Main performance number: Crosschain backed assets Second performance number: Swap time Third performance number: Blockchain supported Functions:

• Develop : Develop, test and deploy cryptographic protocols for crosschain.
• Documentation : Develop documentation & protocols specifications.
• Integrate : Develop offchain backend for relaying transactions from another chains.
• Research : Demo, launch and iterate new ideas. Research state of the art crosschain solutions. Read and analyze articles on topic of blockchain & cryptography, implement and test new algorithms, develop demos and convert them to products that can deliver value to client.
• Unit Testing : Increase test coverage according to specifications.

Requirement skills and experience: Brilliant engineering, math and problem-solving skills (ACM/ICPC finalist level). 3+ years experience in Golang. Experience in blockchain development is a must. Strong experience in one of C++/C#/Java. Solid theoretical background. Experience in solidity as a plus. Result-oriented diligent self-starter with a strong work ethic. Motivated to deliver world-changing solutions by solving hard math and engineering problems. Ability to clearly structure goals and achieve results. Fluent English.
