Swap WBTC from Ethereum to USDT on Arbitrum One
Swap WBTC from Ethereum to USDT on Arbitrum One. A chain 42161 payment in Tether can start from wrapped bitcoin held as an ERC-20 on Ethereum.
Approve WBTC at 0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599 on Etherscan, 8 decimals. It is not a Bitcoin-network coin. Receive 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9 on Arbiscan, Tether on Arbitrum One, 6 decimals. Ethereum USDT at 0xdAC17F958D2ee523a2206206994597C13D831ec7 is not the balance that increases. You pay ETH gas on chain id 1, where a block takes about 12 seconds. The recipient must be on Arbitrum One, not Nova, and needs ETH there because the USDT cannot pay gas. The recipient has to be on chain id 42161, watching Arbiscan, or the Tether payment is invisible. An Etherscan watch will not update.

Frequently asked questions
What is the best way to swap WBTC from Ethereum to USDT on Arbitrum One?
Approve WBTC at 0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599 on Etherscan, 8 decimals. It is not a Bitcoin-network coin.
Is WBTC bitcoin for this payment?
No. WBTC at 0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599 is an ERC-20 on Ethereum, 8 decimals, checked on Etherscan. This route spends it and pays Arbitrum USDT. A Bitcoin wallet cannot hold either token. Treat the position as an Ethereum asset until you redeem it through a separate process.
Which Tether should the recipient watch?
Arbiscan for 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9, on Arbitrum One, chain id 42161. Watching Etherscan for 0xdAC17F958D2ee523a2206206994597C13D831ec7 will show no change. Ask them to switch networks, and not to Nova. The token uses 6 decimals and is still a different contract from Ethereum USDT.
What if I am still trading on Ethereum?
Stay there. WBTC and Tether already have a mainnet market, and the output is 0xdAC17F958D2ee523a2206206994597C13D831ec7. This bridge is the wrong tool for that market. Use it when the Tether has to be the Arbitrum contract because the next wallet or pool is on chain 42161.
