JUSDD Swap
Questions Answered
Everything you need to know about JUSDD Swap, staking, bridging, pools and DeFi credit on TRON.
What is JUSDD Swap?+
JUSDD Swap is a comprehensive DeFi protocol built natively on TRON network. It combines a DEX aggregator (Swap), cross-chain asset bridge (Bridge), liquidity pools (Pool), token staking (Staking), and collateralized borrowing (Credit) into a single non-custodial interface. JUSDD requires no account registration or KYC — only a compatible TronLink or WalletConnect wallet.
What is the JUSDD token?+
JUSDD is the native TRC-20 utility and governance token of the JUSDD Swap protocol on TRON. Holders use JUSDD to pay reduced swap fees, stake for protocol revenue sharing, vote on governance proposals, and access priority features like JUSDD Credit borrowing. JUSDD token can be swapped directly on JUSDD Swap or acquired through liquidity provision.
How do I use JUSDD Swap to exchange TRC20 tokens?+
Click "Connect Wallet" and connect your TronLink wallet. Select the Swap tab, choose your input token (e.g., USDT TRC20) and your output token (e.g., JUSDD or TRX). Enter the amount you wish to swap. JUSDD Swap will quote you the best route across all TRON DEX pools. Review the rate and click "Swap Now" to confirm in TronLink. Your tokens arrive in your wallet in under 3 seconds thanks to TRON's fast block finality.
How does JUSDD Staking work?+
JUSDD Staking lets you deposit JUSDD tokens into the protocol's staking smart contract on TRON. In return, you earn a share of all JUSDD Swap protocol fees — paid out daily in JUSDD and USDT TRC20. There is no mandatory lock-up period; you can unstake JUSDD at any time. The more JUSDD you stake, the greater your share of daily protocol rewards.
What APY can I earn by staking JUSDD?+
JUSDD staking APY is variable and depends on the total JUSDD staked and the daily volume of swaps on JUSDD Swap. The base flexible staking APY can reach up to 42% during high-volume periods. Longer voluntary lock-up periods (30, 90, 180 days) unlock boosted multipliers that further increase your effective JUSDD staking APY. All APY figures are displayed in real-time after connecting your wallet.
Is there a lock-up period for JUSDD staking?+
JUSDD's default staking mode is fully flexible — no lock-up period is required. You can stake and unstake JUSDD tokens at any time without penalty. Optional locked staking terms (30, 90, 180 days) are available for users who want higher reward multipliers in exchange for agreeing to a fixed staking duration. The flexible pool is recommended for new JUSDD stakers.
What chains does JUSDD Bridge support?+
JUSDD Bridge currently supports 30+ networks including TRON, Ethereum, BNB Chain, Polygon, Arbitrum, Optimism, Avalanche, Solana, Fantom, zkSync Era, Celo, Cronos and Cosmos. The bridge handles USDT, USDC, TRX, WBTC, ETH, and hundreds of additional tokens. JUSDD Bridge uses atomic cross-chain settlement to ensure your assets always arrive safely or are returned to you.
How long does a JUSDD Bridge transfer take?+
TRON-to-TRON JUSDD swaps complete in under 3 seconds. Cross-chain JUSDD Bridge transfers from TRON to Ethereum typically take 2–5 minutes, while TRON to BNB Chain or Polygon bridges usually settle in 1–3 minutes. Times vary depending on the destination chain's block confirmation requirements. JUSDD Bridge always shows the estimated arrival time before you confirm a transfer.
How do JUSDD liquidity pools work?+
JUSDD Pool allows any user to deposit a pair of TRC20 tokens (e.g., JUSDD and USDT) into a liquidity pool smart contract on TRON. In exchange, you receive JUSDD LP tokens representing your share of the pool. Every time a trader uses JUSDD Swap to exchange those tokens, a portion of the trading fee is distributed proportionally to all LP token holders. You can withdraw your liquidity plus earned fees at any time.
What is JUSDD Credit and how does it work?+
JUSDD Credit is a decentralized collateralized lending protocol on TRON. Deposit JUSDD tokens or TRX as collateral, and borrow USDT TRC20 or other supported assets up to a specified loan-to-value ratio. Interest accrues on the borrowed amount, and your collateral remains on-chain in the JUSDD smart contract until you repay. No credit checks, no KYC, and instant approval — purely determined by your on-chain collateral.
What fees does JUSDD Swap charge?+
JUSDD Swap charges a protocol fee starting at 0.01% of the swap value — one of the lowest in the TRON DeFi ecosystem. Users holding JUSDD tokens receive an additional fee discount. You also pay the TRON network gas fee, which is typically under $0.01 per transaction. All fees are included in the displayed quote — there are no hidden charges on any JUSDD Swap transaction.
Does JUSDD require KYC verification?+
No. JUSDD Swap is a fully non-custodial decentralized protocol. No account registration, email address, identity document, or KYC verification is ever required. The only thing you need to use JUSDD Swap is a compatible crypto wallet — TronLink for TRON swaps, or MetaMask/WalletConnect for EVM chain swaps. JUSDD never holds your funds or collects your personal data.
Which wallets are compatible with JUSDD Swap?+
JUSDD Swap supports TronLink (recommended for TRON swaps), MetaMask, Trust Wallet, WalletConnect (200+ wallets), Coinbase Wallet, Ledger hardware wallet, Trezor hardware wallet, Phantom (for Solana bridge), and all major browser extension wallets. For swapping JUSDD or any TRC20 token, TronLink is the primary recommended wallet for the best experience.
Is JUSDD Swap safe and audited?+
Yes. JUSDD Swap's smart contracts on TRON have been audited by leading blockchain security firms. The protocol is fully non-custodial — your tokens never leave your wallet until the swap transaction executes atomically on-chain. JUSDD also features MEV protection via private mempool routing, which prevents front-running attacks. If a swap cannot complete, all assets are automatically returned to your wallet.
What is MEV protection on JUSDD Swap?+
MEV (Maximal Extractable Value) bots scan public mempools and front-run swap transactions, forcing users to get worse prices. JUSDD Swap routes all transactions through private TRON mempools, making your swap invisible to bots before it confirms. This MEV protection saves JUSDD users significant value on large swaps — the larger the trade, the more value MEV protection preserves for you.
How does JUSDD find the best swap rate?+
JUSDD's routing engine simultaneously queries 500+ DEX liquidity sources on TRON and connected chains — including SunSwap, JustSwap, Curve, Uniswap V3, PancakeSwap, and many more. It uses a smart pathfinding algorithm to split orders across multiple pools to minimize price impact and maximize output. Quotes refresh every 5 seconds to ensure accuracy. JUSDD guarantees to match any better rate found within 30 seconds of your quote.
Can I swap USDT TRC20 directly on JUSDD?+
Yes. USDT TRC20 is one of the highest-volume tokens on JUSDD Swap. You can swap USDT TRC20 for JUSDD, TRX, BTT, JST, SUN, WIN, or any other TRC20 token in seconds. You can also bridge USDT from Ethereum (ERC20) or BNB Chain (BEP20) to TRON TRC20 via JUSDD Bridge in a single step without visiting a centralized exchange.
What is slippage and how do I set it on JUSDD Swap?+
Slippage is the acceptable difference between your quoted price and the executed price, caused by market movement between quote time and block confirmation. For most TRON stablecoin swaps on JUSDD, 0.1% to 0.5% slippage is sufficient. For volatile TRC20 tokens or very large JUSDD trades, set 1% or use the "Auto" mode. JUSDD's Auto slippage dynamically chooses the optimal tolerance based on each token pair's recent volatility.
Can I get a JUSDD swap quote without connecting a wallet?+
Yes. You can preview quotes and explore JUSDD swap routes without connecting a wallet. Live rate quotes, route breakdowns, and fee estimates are all visible before wallet connection. To execute a swap, bridge, stake JUSDD, or access JUSDD Credit, you must connect a supported wallet. No personal data or account creation is ever required.
How do I earn rewards from JUSDD liquidity pools?+
When you provide liquidity to JUSDD pools, you receive JUSDD LP tokens. These LP tokens automatically accumulate a share of all swap fees generated by the pool. When you redeem your JUSDD LP tokens (withdraw liquidity), you receive your original deposit plus all accumulated fees. Some JUSDD pools also distribute additional JUSDD token incentives on top of trading fee rewards for extra yield.
What is impermanent loss and does it affect JUSDD pools?+
Impermanent loss (IL) occurs when the price ratio of your deposited tokens diverges from when you entered the pool. It affects all AMM liquidity pools, including JUSDD pools. Stablecoin-to-stablecoin JUSDD pools (e.g., USDT/USDC) have negligible IL since their prices stay close. JUSDD/USDT pools may have moderate IL depending on JUSDD price movements. JUSDD's high trading fees and additional JUSDD incentives are designed to offset IL for long-term liquidity providers.
Does JUSDD have a governance system?+
Yes. JUSDD token holders and stakers have on-chain governance rights. Staked JUSDD tokens grant voting power on protocol proposals, including changes to fee structures, supported chains, new pool incentives, JUSDD tokenomics, and smart contract upgrades. One staked JUSDD equals one governance vote. Proposals and voting are executed entirely on-chain via TRON smart contracts, ensuring transparent and tamper-proof governance.
What collateral does JUSDD Credit accept?+
JUSDD Credit currently accepts JUSDD tokens, TRX, USDT TRC20, BTT, and selected high-liquidity TRC20 assets as collateral. Collateral values are assessed in real-time by JUSDD's on-chain price oracle system. The maximum loan-to-value (LTV) ratio depends on the collateral asset's liquidity and volatility. JUSDD Credit borrowers must maintain a minimum health factor to avoid liquidation of their collateral position.
How does JUSDD protect against liquidation?+
JUSDD Credit displays a real-time health factor for each borrowing position after wallet connection. When the health factor drops below 1.0 due to collateral price decline, the JUSDD liquidation module allows external liquidators to repay part of the debt and receive the collateral at a discount. To avoid liquidation, JUSDD users can add more collateral or repay part of their loan at any time. JUSDD Credit sends health-factor warnings before a liquidation threshold is reached.
Can I use JUSDD Swap on mobile?+
Yes. JUSDD Swap is fully responsive and optimized for mobile browsers. Open JUSDD Swap in the TronLink mobile app's built-in browser for the best TRON experience on iOS and Android. WalletConnect support also enables any mobile wallet to connect to JUSDD Swap through a QR code scan. All five JUSDD modules — Swap, Bridge, Pool, Staking, and Credit — are accessible on mobile.
What is the JUSDD referral or affiliate program?+
JUSDD operates a decentralized referral program where you can generate a unique on-chain referral link. When users swap, stake, or provide liquidity via your JUSDD referral link, you earn a percentage of the protocol fee from every transaction they complete — paid directly to your TronLink wallet in real-time. JUSDD referral rewards are stackable with staking rewards and have no cap on earnings.
How does JUSDD handle failed or stuck transactions?+
JUSDD Swap uses atomic execution: a swap either completes fully or reverts entirely. No partial fills result in lost funds. If a TRON transaction fails (e.g., price moved beyond slippage tolerance), all tokens are returned to your wallet automatically — you only pay the minimal TRON network gas fee. JUSDD's status tracker in the interface lets you monitor every transaction in real-time on the TRON blockchain.
Does JUSDD Swap support limit orders?+
Yes. JUSDD Swap offers a limit order feature for TRC20 token pairs. Set your desired price, and JUSDD's decentralized order-book keeper network will execute your swap automatically when the market hits your target rate — without you needing to stay online. Limit orders on JUSDD are non-custodial: your tokens stay in your wallet until the order fills. Unfilled orders can be cancelled at any time for no extra fee.
What tokens can I swap on JUSDD?+
JUSDD Swap supports all TRC20 tokens listed on TRON's major DEXes, including USDT, USDC, TRX, BTT, JST, SUN, WIN, NFT, USDJ, JUST, and of course the JUSDD token itself. You can also swap any token from connected chains (ETH, BNB, MATIC, SOL, etc.) via JUSDD's cross-chain bridge integration. New tokens are automatically available as liquidity is added to any supported DEX pool.
How does JUSDD compare to SunSwap and JustSwap?+
SunSwap and JustSwap are single DEXes — JUSDD Swap is an aggregator that routes across SunSwap, JustSwap, and 500+ other liquidity pools simultaneously. This means JUSDD almost always finds a better rate than trading directly on any single DEX. Beyond swapping, JUSDD uniquely combines cross-chain bridging, staking, pools, and DeFi credit into one protocol — making it a complete TRON DeFi hub rather than a simple token exchange.
Can I add my own TRC20 token to JUSDD Swap?+
Yes. Any standard TRC20 token is automatically available on JUSDD Swap once it has liquidity on at least one supported TRON DEX. Project teams can also submit their token for inclusion in the JUSDD token list by applying through the JUSDD governance process. Users can manually add any custom TRC20 token address directly in the JUSDD Swap interface by pasting the contract address.
What is the JUSDD token contract address on TRON?+
The official JUSDD token contract address on TRON is published on the JUSDD Swap documentation page and verified on TRONSCAN. Always verify the JUSDD contract address against the official JUSDD Swap website (jusdd-swap.eu.cc) and our official social channels before trading. Be cautious of fake JUSDD tokens or unofficial contract addresses circulated on unofficial platforms.
Does JUSDD Swap have a native token airdrop program?+
JUSDD distributes a portion of JUSDD token supply to early protocol users, liquidity providers, and long-term stakers via periodic airdrop snapshots. Eligibility criteria, snapshot dates, and claim processes are announced through the official JUSDD Swap channels (Telegram, Twitter/X, Discord). Beware of scam airdrops — JUSDD never asks for private keys or sends unsolicited messages requesting you to connect to third-party sites.
How do I track my JUSDD staking rewards and positions?+
After connecting your TronLink wallet on JUSDD Swap, the Staking tab displays your complete dashboard: total JUSDD staked, accumulated unclaimed rewards (in JUSDD and USDT), estimated daily earnings, your staking APY, lock-up status (if applicable), and governance voting power. You can claim rewards at any time or enable auto-compound to reinvest JUSDD rewards back into staking automatically for maximum compounding yield.
Where can I get support for JUSDD Swap?+
JUSDD Swap support is available through the official Telegram community, Discord server, and the Documentation portal at jusdd-swap.eu.cc/docs. The JUSDD team monitors all official channels and typically responds within a few hours. For transaction-specific issues, always have your TRON transaction hash (TXID) ready so the support team can investigate quickly. Never share your private key or seed phrase with anyone claiming to offer JUSDD support.
