TxFlow Mainnet: access and trading capital
TxFlow is a standalone L1 with its own execution and settlement. The official Arbitrum deposit brings USDC into a TxFlow trading account; the source wallet and the account keep separate balances.

Fund the Arbitrum route with native USDC
The official Arbitrum deposit accepts Circle-issued USDC. A connected-wallet deposit normally uses ETH on Arbitrum. Gas-Free Deposit pays the gas for an external self-custody wallet, whose private keys you control, with exactly zero Arbitrum ETH.

| Route | Required balance | Who submits the deposit |
|---|---|---|
| Standard wallet deposit | Native USDC and ETH on Arbitrum | Your wallet submits the transaction |
| Gas-Free Deposit | At least 5 native USDC; exactly 0 ETH on Arbitrum | TxFlow submits the transaction after your authorization |
Fund a TxFlow trading account
TxFlow mainnet requires an access code. The primary trading-account deposit route uses native USDC on Arbitrum.
Trading permission
Enter an access code, then select Enable Trading and sign the authorization. Codes are distributed through the official Discord.
Deposit USDC
Open Deposit. The Arbitrum route uses native USDC at contract 0xaf88…5831. It does not accept USDC.e.
Withdraw USDC
Open Withdraw, enter an amount and a destination address. History is available in Portfolio → Deposits & Withdrawals. Fees depend on the selected network.
Source ↗Markets on a shared L1
From buying an asset to trading an outcome
TxFlow DEX offers spot markets and perpetual futures. TxFlow also provides Probly prediction markets that settle on an event's outcome.
Buy and sell
TxFlow Spot
The buyer receives the selected asset and the seller receives the quote asset. The deposit form provides a token-specific address and source network.
Perpetual futures
TxFlow Perpetuals
Open long or short positions on crypto, equities and other underlying assets. Margin backs the position, while funding links the contract price to its reference market.
Prediction markets
Probly
Choose an event outcome and place an order in the book. After resolution, a winning share pays 1 dollar and a losing share pays 0; positions can be sold before settlement.
TIP: shared settlement and data
How capital works across three markets
Markets share the TxFlow chain but create different positions. A spot purchase, futures collateral and an event-outcome share have different settlement rules.
Spot
- 01Quote asset
- 02Executed order
- 03Purchased asset
The operation exchanges one asset for another. Spot purchases have no leverage or funding payments.
Mechanics and terms ↗Perpetuals
- 01USDC margin
- 02Long or short position
- 03Profit or loss
The trader receives exposure to price changes, with collateral backing the position. Funding payments pass between the two sides while positions remain open.
Mechanics and terms ↗Predictions
- 01Share price
- 02Selected outcome
- 031 dollar or 0
The market settles after its event outcome is established. Trading fees are separate; this market has no funding payments or leverage.
Mechanics and terms ↗USDC margin can back one position or a shared account
Cross Margin shares USDC collateral and unrealized results across cross-margin positions. Isolated Margin assigns collateral to one position. The chosen mode determines which balance absorbs that position's losses.
| Mode | Collateral | Where losses are absorbed |
|---|---|---|
| Cross Margin | Shared collateral pool | Account equity across cross-margin positions |
| Isolated Margin | Collateral assigned to one position | That position's allocated margin |
Illustrative initial margin
A $1,000 position at 5× leverage requires $200 initial margin before trading fees and later price changes. The $1,000 position size is the exposure; $200 is the collateral used to open it.
$1,000 ÷ 5 = $200 initial margin
Deposit chain and trading balance
USDC on Arbitrum is the entry asset. After deposit, positions and settlement live on TxFlow; your Arbitrum wallet balance and trading balance are separate amounts.
Native USDC
The official Arbitrum route accepts USDC at 0xaf88d065e77c8cC2239327C5EDb3A432268e5831. USDC.e uses a different contract.
Spot deposits
Select a token in Spot and use its generated address and network. The USDC trading-account deposit address is not a universal route for every asset.
Position margin
Collateral covers potential losses on a futures position. An equity perpetual provides price exposure; it does not deliver a share to a brokerage account.
Gas-Free Deposit authorizes one exact payment
The authorization covers the entered USDC amount and the official bridge recipient. Signing itself costs no gas; TxFlow pays for the onchain submission. The authorization expires after 60 minutes, after which the deposit flow can issue a new signature request.

What traders pay for
Deposit gas, trading fees and funding are calculated separately.
Deposit
A standard wallet deposit requires ETH on Arbitrum. Gas-Free Deposit is available to standard EVM wallets with exactly zero ETH on Arbitrum, starting at 5 native USDC. You sign an authorization and TxFlow submits the transaction and pays its gas.
Order execution
Perpetual fees are charged on the executed notional. Opening and closing are charged separately; tiers depend on order role and combined spot and perpetual volume over 14 days.
Funding
Payments pass between long and short position holders. The interval depends on the contract; only positions held at the settlement timestamp pay or receive funding.
Protocol Vault and User Vaults
Vaults deploy capital into trading strategies. Access remains limited during the early mainnet phase.
Protocol Vault
The protocol vault makes markets and handles backstop liquidations. User deposits are not yet open.
User Vaults
User vaults run strategies managed by individual traders. Creation is limited to a pilot group; the manager receives 10% of strategy profits.
TxFlow, TxCore and TxEVM
TxFlow is a standalone layer 1 for financial applications. TIP standards connect markets to shared settlement, market data and liquidity access.
TxCore
The native trading engine executes order books, checks margin and handles liquidations in a shared state machine.
TxEVM
The Solidity environment runs in the same block stream. It supports stablecoins, swaps, lending and other applications.
Market modules
A module defines product rules, fees and risk parameters. Applications build trading interfaces or strategies on top.
Which wallet can fund the account?
EVM-wallet onboarding requires a standard EOA account. This route does not support AA smart accounts.
Standard account
MetaMask and Rabby can be used with a regular key-controlled account. Sign the Enable Trading authorization in your wallet.
Smart account
An AA-wallet deposit can lock trading and withdrawals. This account type is excluded from the supported deposit route.
