Injective Trading Account

Injective Trading Account, Skill Guide

Query balances and open positions for any Injective account. No transactions/ signatures required. All reads are public.

When to apply

• When you are trading on Injective, and need information about your account
• When you are performing queries but not intending to perform transactions

MCP Tools

The following tools in the Injective MCP Server are used by this skill. Use the injective-mcp-servers skill for instructions on set up and usage. The "activities" section describes the when and how to make these tool calls.

account_balances

Returns bank + subaccount balances for an address.

account_balances
  address: inj1...
  denom: usdt         ← optional: filter to one token

Returns:

• bankBalances[] - wallet-level balances (all denoms or filtered)
• subaccountBalances[] - per-subaccount trading balances
  • subaccountId - 0x... hex ID
  • denom - token denom
  • deposit.totalBalance - total (available + in orders)
  • deposit.availableBalance - free to trade

account_positions

Returns open perpetual positions with P&L.

account_positions
  address: inj1...
  market: BTC         ← optional: filter by symbol

Returns per position:

• market - symbol (BTC, ETH, etc.)
• direction - long | short
• quantity - contracts held
• entryPrice - average entry in USDT
• markPrice - current oracle price
• unrealizedPnl - USDT P&L at mark price
• margin - posted margin
• leverage - effective leverage

token_metadata

Resolve any denom to human-readable metadata.

token_metadata
  denom: peggy0xdac17f958d2ee523a2206206994597c13d831ec7

Returns: { symbol, name, decimals, type, peggyDenom }

Activities

When the user's request contains the following questions, map them to the MCP tool calls indicated.

"What's my balance?"

account_balances(address: inj1...)
→ show bankBalances + subaccountBalances summary

"Do I have enough USDT to trade?"

account_balances(address: inj1..., denom: usdt)
→ check subaccountBalances[0].deposit.availableBalance

If bank balance has USDT but subaccount doesn't: Use subaccount_deposit to move funds in. Note that this is not a read/ query, and will involve a transaction.

Important: Bank balance (wallet) ≠ exchange subaccount balance. Funds must be deposited to the exchange subaccount via MsgDeposit before placing derivative orders. Always check subaccount balance and auto-deposit if needed before trading.

"Show my positions and P&L"

account_positions(address: inj1...)
→ display each position with entry vs mark price and unrealizedPnl

"What's my total portfolio value?"

account_balances    → sum all balances in USD equivalent
account_positions   → add unrealized P&L

Denoms

Denoms are analogous to cryptocurrencies and fungible tokens. Injective, being a MultiVM blockchain, supports multiple categories of denoms.

Denoms of different categories have different formats. See: ./references/denom-formats.md Use token_metadata to resolve any denom to a human-readable symbol.

Margin Calculation

When estimating required margin for a position:

• Add 1–2% buffer above the exact minimum (price × qty × initialMarginRatio). The chain may reject orders at the exact minimum due to rounding.
• Use max(oraclePrice, markPrice) for margin validation. The chain validates against the higher of the two. Margin calculated from oracle price alone may be insufficient if mark price is higher.
• stakeUsdt is margin, not notional. The user's stake is their margin (collateral). qty = stake × leverage / price.

Subaccount IDs

Injective uses subaccounts for isolated margin.

The default subaccount index is 0: subaccountId = address + "000000000000000000000000" + "0".padStart(24, "0") + "0000"

In practice, the MCP tools default to subaccount index 0 automatically. Advanced users can specify subaccountId explicitly on trade tools.
