1. Introduction & Motivation
Tang Xuliu (TXL) is a personal ERC-20 token deployed on Ethereum mainnet. It was created by Tang Xuliu, an independent developer, as a hands-on project to practice the full lifecycle of token creation and management on a public blockchain.
The motivation behind TXL is practical rather than commercial. The goals of this project include:
- Learning smart contract development — writing, testing, and deploying a standard ERC-20 token contract on Ethereum mainnet
- Implementing a real vesting schedule — building and deploying a time-lock contract that releases tokens on a fixed monthly schedule
- Practicing DeFi integration — creating a trading pair on Uniswap V2, providing liquidity, and managing LP tokens
- Exploring multi-sig custody — using Gnosis Safe for LP token management to understand multi-signature wallet operations
- Building a transparent on-chain presence — maintaining a publicly verifiable record of all token-related activities
TXL does not represent equity, governance rights, or ownership in any entity. It has no affiliation with any company or organization. No fundraising (public or private) has been conducted. This is a self-funded, independently maintained project.
2. Token Specification
- Token Name
- Tang Xuliu
- Symbol
- TXL
- Standard
- ERC-20
- Network
- Ethereum Mainnet
- Total Supply
- 10,000,000 TXL
- Supply Model
- Fixed — no minting or burning functions in the contract
- Decimals
- 18
- Contract Address
- 0x68c98Bb7d641c377B23cC4886d84C16a4eC3d5b8
The contract source code is verified and publicly readable on Etherscan. The token follows the standard ERC-20 interface without custom modifications — no taxes, no transfer restrictions, no admin functions beyond what is needed for basic operation.
3. Token Allocation & Distribution
| Category | Amount | % | Purpose |
|---|---|---|---|
| Initial Circulating | 1,000,000 TXL | 10% | Paired with ETH to create the initial Uniswap V2 liquidity pool |
| Locked (Vesting) | 9,000,000 TXL | 90% | Held in a time-lock smart contract, released monthly over ~60 months |
There was no public sale, private sale, ICO, IEO, airdrop, or any form of fundraising. All 10,000,000 TXL tokens were minted to the creator's address at deployment, then allocated as described above.
4. Vesting Mechanism — Design & Rationale
90% of the total supply (9,000,000 TXL) is locked in a dedicated time-lock smart contract. The mechanism works as follows:
- Locked Amount
- 9,000,000 TXL
- Release Rate
- 150,000 TXL per month
- Release Duration
- ~60 months (5 years)
- Release Method
- On-chain claim from the lock contract; each release is a verifiable transaction
- Lock Contract
- 0xb0f535a1aCbBE03164FF3F1d8F2EcdeD5d2Bd6c9
Why this design?
The vesting parameters were chosen based on practical considerations:
- 90/10 split — Starting with only 10% in circulation keeps the initial floating supply small. This was a deliberate choice to practice how projects manage circulating supply relative to total supply.
- 150,000 TXL/month — At 1.5% of total supply per month, this creates a steady, predictable release that is easy to track and verify. The number was chosen to produce a release period of approximately 5 years, which is a common timeframe in real token vesting schedules.
- Smart contract enforcement — The lock is enforced by the contract code, not by a promise. Anyone can verify the remaining balance and the next release time by reading the contract on Etherscan.
5. Liquidity Setup
The TXL/WETH trading pair was created on Uniswap V2. The initial liquidity was provided by pairing the 1,000,000 TXL circulating supply with ETH from the creator's personal funds.
- DEX
- Uniswap V2
- Pair
- TXL / WETH
- Pair Contract
- 0x544d96690114962De062BcED8566e6f4e6241Df0
- LP Token Custody
- Gnosis Safe multi-signature wallet
- Safe Address
- 0xf339FA7c9c67959791FaB3Dff85cBF40ee6D5C07
Uniswap V2 was chosen because it is one of the most widely used and battle-tested AMM protocols on Ethereum. Setting up a V2 pair is a fundamental exercise in DeFi interaction.
6. Security Measures
While TXL is a personal project, reasonable security practices have been implemented:
- LP tokens in multi-sig — The LP tokens from the Uniswap V2 pair are held in a Gnosis Safe wallet, not in a personal EOA (externally owned account). This means no single private key can withdraw the liquidity.
- Vesting enforced by smart contract — The 9,000,000 locked TXL can only be released according to the contract's programmed schedule. There is no admin override or emergency withdrawal function.
- Source code verified — The token contract source code is verified on Etherscan, allowing anyone to read and audit the contract logic.
- No privileged admin functions — The token contract does not include owner-only functions for minting, pausing, or blacklisting.
7. On-chain Contract References
All addresses above can be independently verified on Ethereum mainnet through any block explorer.
8. About the Creator
TXL is created and maintained by Tang Xuliu, an independent developer with an interest in blockchain technology, smart contract development, and decentralized finance.
This is a solo project. There is no team, no advisory board, no investors, and no external funding. All costs (contract deployment gas fees, initial liquidity ETH) were paid from personal funds.
The project is maintained as a long-term personal commitment. Ongoing responsibilities include monitoring vesting releases, maintaining the website and documentation, and keeping all public information accurate and up to date.
