Get the configured wallet address. This wallet is used for all lending operations.

List all supported TRON networks for JustLend.

List all available JustLend lending markets (jTokens) with their addresses and underlying assets.

Get detailed market data for a specific JustLend market: supply/borrow APY, TVL, utilization, collateral factor, price, and status. Use jToken symbol like 'jUSDT' or 'jTRX'.

Get overview data for ALL JustLend markets including supply APY, borrow APY, mining rewards APY, underlying staking yield, total supply APY, and TVL. Mining APY is calculated from on-chain supply mining programs (USDD/TRX dual mining, WBTC mining, etc.). totalSupplyAPY = base supply APY + underlying staking APY + mining APY.

Get JustLend protocol-level info: Comptroller config, close factor, liquidation incentive, total markets.

Get all market data from JustLend API. More stable than contract queries. Returns comprehensive market data including APY, TVL, utilization, prices, mining rewards, etc.

Get JustLend protocol dashboard from API. Returns protocol-level statistics: total supply, total borrow, TVL, number of suppliers/borrowers, etc.

Get detailed jToken information from API. Returns comprehensive market details including interest rate model, reserve info, etc.

Get a comprehensive view of a user's JustLend positions: supply balances, borrow balances, collateral status, health factor, liquidation risk, and USD values for each market.

Check if the underlying TRC20 token has been approved for a jToken market. Must be approved before supply() or repay() for TRC20 markets. Not needed for jTRX.

Get TRX balance for an address.

Get TRC20 token balance for an address. You can pass either a token symbol (e.g. 'USDD', 'USDT', 'ETH') or a contract address. When using a symbol, it resolves to the correct contract address from JustLend markets automatically. IMPORTANT: Always prefer using token symbols over raw addresses to avoid using outdated/wrong contract addresses. For example, use 'USDD' instead of a raw address — the old USDD (TPYmHEhy5n8TCEfYGqW2rPxsghSfzghPDn) is deprecated. The returned balance is already formatted in human-readable token units (decimals already applied). Do NOT divide the balance by decimals again.

Get user account data from JustLend API. More stable and comprehensive than contract queries. Returns lending positions, balances, mining rewards, health factor, etc.

Supply (deposit) assets into a JustLend market to earn interest. For TRC20 markets, you must first call approve_underlying. For jTRX, TRX is sent directly. Returns a jToken balance representing your deposit. Typical cost: ~100,000 energy + ~310 bandwidth for TRC20, ~80,000 energy + ~280 bandwidth for TRX. Use estimate_lending_energy tool for precise estimates before executing.

Withdraw (redeem) supplied assets from a JustLend market. Specify the amount in underlying units. May fail if assets are used as collateral for active borrows. Typical cost: ~90,000 energy + ~300 bandwidth.

Withdraw ALL supplied assets from a JustLend market by redeeming all jTokens. Typical cost: ~90,000 energy + ~300 bandwidth.

Borrow assets from a JustLend market against your collateral. You must have entered a market as collateral (enter_market) and have sufficient liquidity. Check your account_summary and health_factor before borrowing. Typical cost: ~100,000 energy + ~313 bandwidth.

Repay borrowed assets to a JustLend market. For TRC20 markets, must have approved underlying first. Use amount='max' to repay the full outstanding borrow. Typical cost: 80,00090,000 energy + 280320 bandwidth (TRX costs less than TRC20).

Enable a jToken market as collateral. Required before borrowing against supplied assets. Once entered, your supply in this market counts towards your borrowing capacity. Typical cost: ~80,000 energy + ~300 bandwidth.

Disable a jToken market as collateral. Will fail if doing so would make your account undercollateralized. Check account_summary first to ensure safety. Typical cost: ~50,000 energy + ~280 bandwidth.

Approve the jToken contract to spend your underlying TRC20 tokens. Required before supply() or repay() for TRC20-backed markets (not needed for jTRX). Use amount='max' for unlimited approval. Typical cost: ~23,000 energy + ~265 bandwidth.

Claim accrued JustLend mining rewards for the configured wallet. Typical cost: ~60,000 energy + ~330 bandwidth.

Estimate energy, bandwidth, and TRX cost for any JustLend operation BEFORE executing it. Covers ALL operations: supply, withdraw, withdraw_all, borrow, repay, approve, enter_market, exit_market, claim_rewards. Tries on-chain simulation first; falls back to historical typical values if simulation fails. Returns per-step breakdown (e.g. approve + mint for supply), total energy, total bandwidth, and estimated TRX cost. For supply/repay: automatically checks current allowance — if sufficient, the approve step is skipped. For approve: supports custom spender address (not just jToken). Use this tool whenever the user asks about gas/energy/cost for any lending operation.

Get mining rewards for supply markets (USDD, WBTC, etc.). Returns unclaimed rewards, mining APY, and reward breakdown from API.

Get USDD mining configuration including mining periods, reward tokens (USDD/TRX dual mining), and schedule.

Get WBTC mining configuration and supply mining activity details.

Get the list of JustLend DAO governance proposals. Returns proposals with their status (Active, Passed, Defeated, etc.), vote counts, and details. Sorted by newest first.

Get a user's voting status across all governance proposals. Shows which proposals the user has voted on, their vote amounts (for/against/abstain), and which proposals have withdrawable votes.

Get voting power info for a user: JST wallet balance, available (surplus) votes, total deposited votes, and votes currently cast in proposals. This is the key tool to check before voting — it shows how many votes are available to use.

Get the number of votes a user has locked in a specific proposal.

Check if JST has been approved for the WJST voting contract. Must be approved before depositing JST to get votes.

Approve JST token for the WJST voting contract. Required before depositing JST to get voting power. Use amount='max' for unlimited approval.

Deposit JST into the WJST contract to get voting power. Requires prior approval of JST for the WJST contract (use approve_jst_for_voting first). 1 JST = 1 Vote. Deposited JST can be withdrawn back after voting.

Withdraw WJST back to JST. Can only withdraw votes that are not currently locked in active proposals. Use get_vote_info to check your surplus (available) votes before withdrawing.

Cast a vote on a governance proposal. You must have available votes (deposit JST first if needed). Support: true = vote FOR, false = vote AGAINST. You can add more votes to a proposal you already voted on.

Withdraw (reclaim) votes from a completed or canceled proposal. Only works for proposals that are no longer active. After withdrawing, the votes become available again for other proposals or can be converted back to JST.
