Swap USDT from Ethereum to ARB on Arbitrum One
Swap USDT from Ethereum to ARB on Arbitrum One. Someone who wants the ARB token on chain 42161 spends Ethereum Tether and receives that governance token.
ARB is 0x912CE59144191C1204E64559FE8253a0e49E6548 on Arbiscan. It does not pay gas. Gas on Arbitrum One is ETH, separate from ETH on Ethereum. You approve Tether at 0xdAC17F958D2ee523a2206206994597C13D831ec7 on Etherscan, 6 decimals. The destination is chain id 42161, not Arbitrum Nova. If your Tether is already the Arbitrum contract 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9, buy ARB there. This page starts from mainnet Tether and still needs ETH on chain id 1. Blocks there are about 12 seconds. Switch to Arbitrum One and import the ARB contract from Arbiscan before you try to move it.

Does ARB pay gas on Arbitrum One?
No. The token at 0x912CE59144191C1204E64559FE8253a0e49E6548 is an ERC-20. Gas is ETH on chain id 42161. ETH on Ethereum is a different balance and does not cover those fees. If you needed gas, pick a route that outputs native ETH. Use this pair when the ARB token itself is the position.
Which USDT do I approve?
Ethereum Tether at 0xdAC17F958D2ee523a2206206994597C13D831ec7 on Etherscan. Keep ETH beside it for chain id 1 gas. Blocks are about 12 seconds.

Will I see ARB if my wallet is on Nova?
No. This route delivers ARB on Arbitrum One, chain id 42161. Nova is a different network. Set the wallet to Arbitrum One and read 0x912CE59144191C1204E64559FE8253a0e49E6548 on Arbiscan. The Ethereum wallet will not show that token in its mainnet list. Set the network before you search for the token.
