Ethereum and Base

Ethereum and Base share BRO-ker's EVM trading workflow while keeping their wallets, balances, contracts, settings, and histories separate. Both support ERC-20 swaps, limit orders, copy trading, bridge routes, portfolio tracking, and private transaction delivery where available.

Never send an asset merely because the destination address has the same hexadecimal form. The sending and receiving networks must match.

Open an ERC-20 token

Select ETH or BASE, then paste the exact 0x contract into the private chat. BRO-ker reads available contract metadata, market information, route availability, the active wallet's token balance, and BRO-ker-tracked position data.

The EVM token view can show:

• name, symbol, decimals, and contract;
• price, market cap, liquidity, and risk indicators when available;
• native and token balances for the selected wallet;
• average entry, initial amount at risk, open limits, and PnL;
• buy and sell controls;
• latest route information;
• explorer and external market links.

Contract addresses are network-specific. A contract that exists on Ethereum can be absent or represent a different asset on Base.

Quotes and routes

BRO-ker requests live EVM liquidity and displays the route sources returned with the quote. A path can combine one or more venues. The best visible route can change between requests as gas, liquidity, and token prices move.

Buying

Buy with ETH or USDC using configured buttons, a custom amount, or an available supply-percentage calculation. Keep ETH in the same network wallet for gas even when buying with USDC.

Gas mode controls how BRO-ker prioritises the transaction. Faster settings can increase the fee without guaranteeing immediate inclusion.

Selling and approvals

An ERC-20 token must normally grant a spender permission before it can be swapped. If the allowance is insufficient, BRO-ker presents an approval step before the sale.

An approval is not the sale. It spends gas and creates an on-chain permission. After it confirms, request a fresh sell quote. Avoid broad approvals you do not understand and consider reviewing or revoking unused allowances with a reputable network-specific tool.

Fee-on-transfer, rebasing, restricted, or otherwise non-standard tokens can fail or return a different amount despite passing basic metadata checks.

Privacy and transaction delivery

Ethereum and Base can use a private submission path when enabled and available. This can reduce exposure to the public mempool, but it does not make a transaction invisible on-chain and does not guarantee MEV protection or execution.

Holdings and scan history

Network portfolios combine the active wallet's native and stable balances with supported or recently tracked tokens. The EVM watchlist is a recent contract-scan history, making it easy to reopen tokens you viewed on that network. It is not the same threshold-alert system used on Solana.

Use the network's explorer as the final source of truth for balances, approvals, and transaction results.
