Trading on Monad

Monad spot trading is beta. Same UX surface as Solana — buy, sell by percentage, sell exact amount — with a different execution engine underneath.

::: warning Beta status Monad trading works but has narrower feature coverage than Solana. See What's unavailable on Monad below. :::

What Interstate routes through

Protocol	Coverage
Uniswap V2	Constant-product pools
Uniswap V3	0.05%, 0.3%, 1% fee tiers
Universal Router	Trade path aggregation

Pool discovery queries Uniswap V2 and V3 factory contracts and picks the highest-TVL pool for the token.

Native asset

Asset	MON

You pay for trades in MON and the platform denominates sells in MON. ERC-20 tokens on Monad are traded against native MON.

10 MON reserve

::: danger 10 MON must remain in your wallet at all times The pre-check on every Monad trade enforces this. A trade that would drop your MON balance below 10 MON after gas and value transfer is rejected. This keeps your wallet funded for future gas. :::

Plan trade sizes to leave at least 10 MON headroom plus an estimate for gas.

Gas — charged on gasLimit, not on use

::: warning Monad charges gas on gasLimit, not gasUsed Unlike Ethereum mainnet, Monad charges you for the full gasLimit you send — not just what the transaction actually consumed. :::

To avoid overpaying while still ensuring trades land:

Interstate adds a 10% buffer to its gas estimate.
Gas is capped at 30 million per transaction.

You don't set this manually. The pre-check endpoint handles it. But know that your MON cost per trade is higher than it would be on a gas-refund chain.

Finality

State	Timing
Voted / speculative (receipt available)	~400ms
Finalized	~800ms

Interstate treats Finalized as the execution confirmation for portfolio updates. Receipts surface faster but are not final.

Chain IDs

Network	Chain ID
Monad mainnet	143
Monad testnet	10143

How trading works

Navigate to app.interstate.so/trade/monad/[contractAddress], or switch the chain in the header BlockchainSwitcher.
Enter an amount (MON for buys; % or tokens for sells).
Confirm.
Pool discovery picks the highest-TVL Uniswap V2 / V3 pool.
The tx signs and submits via your Turnkey wallet.
Portfolio updates once the tx is Finalized.
