In order to optimize users' on-chain interactive experience and reduce the overall cost of transactions, UKey Wallet client has now officially launched two core functional modules: TRON network transaction fee subsidy and automatic energy leasing, and stablecoin zero-fee exchange service in a multi-chain environment. The following is the technical description and business execution rules of related functions.
1. TRON Network: Transfer Subsidy and Automatic Energy Leasing Mechanism
1. Handling fee subsidy program rules
In view of the resource billing characteristics of the TRON network, UKey officially provides a network fee (Gas Fee) subsidy amount. The specific operating standards are as follows:
Total amount released: The system automatically releases 1,000 subsidy quotas every day.
Address limit: A single independent chain address is limited to one claim every 24 hours, and the cumulative limit is 10 times per natural month.
Network restrictions: A single IP address is limited to 15 times per calendar month (note: using a proxy or VPN node may affect claim eligibility due to IP conflicts).
Time limit mechanism: The effective window period after the subsidy is received is 10 minutes. Transfer transactions broadcast through UKey during this period can automatically deduct the corresponding handling fee.
Prerequisite: The TRX balance in the target account must be greater than 0 (that is, the account has been activated on the TRON main network) before you can use the free transfer subsidy for tokens such as USDT.
Operation Guide: When the user constructs a transaction on the TRON chain in UKey Wallet, if the conditions are met, the system interface will automatically display the entrance to receive the subsidy, and click to confirm to deduct it.
2. Automatic energy leasing and payment relay
UKey Provides automated resource status monitoring and relay leasing services. The specific execution rules are as follows:
Dynamic evaluation: During the transfer initiation phase, the system will automatically evaluate the bandwidth and energy required for the transaction. If insufficient available resources are detected, the system will determine whether to display energy leasing prompts based on the transfer scenario; the following special rules for USDT transfers will take precedence.
Special rules for USDT transfers: When using the transfer function to send USDT on the TRON network, if the available energy in the account is less than 64,000, the system will hide the energy leasing entrance. The handling fee corresponding to the insufficient energy will be paid in TRX and deducted from the user's TRX balance.
USDT payment: In scenarios where energy leasing is supported, the leasing relay service supports the use of USDT for settlement. Even if there is a lack of TRX in the account to pay mining fees, the system can complete energy leasing by deducting a small amount of USDT. This mechanism does not apply to the above USDT transfer scenario where the available energy is less than 64,000.
2. Multi-chain stable currency exchange: zero handling fee and zero slippage mechanism
In order to eliminate the "hidden costs" (such as uncontrollable slippage, exchange rate differences and transit path losses) generated when different stablecoin assets are transferred across pools, the UKey routing protocol has now fully upgraded the stablecoin internal exchange (Swap) module.
1. Support network and asset scope
Supported networks: The current blockchain networks that have achieved zero-fee redemption include Ethereum, Arbitrum, Optimism, BNB Chain, Polygon and TRON. This network list will be continuously evaluated and supported as it expands.
Supported assets: Covers a combination of USDT, USDC, DAI and other mainstream legal currency-anchored assets.
2. Enforcement standards and transparency
Zero additional fees: When conducting mutual exchange of stable coins specified above, the UKey protocol layer does not charge any additional business fees to users.
Transparent settlement: All exchange logic is executed based on the decentralized on-chain liquidity pool. By optimizing routing, the system strictly locks the exchange rate and eliminates preset slippage risks to the greatest extent. The entire transaction process can be viewed on the chain, and no exchange rate spread space is set.
3. Official deployment recommendations
UKey is committed to continuously simplifying operating procedures and lowering the threshold for on-chain interaction while ensuring the bottom line of physical hardware-level security. In order to properly call the above subsidy interface and exchange agreement, please be sure to update your mobile UKey Wallet application or browser extension to the latest official version.
