What network do I use to transfer to Coinbase?
Coinbase Wallet supports Ethereum and all EVM-compatible networks in both the mobile app and browser extension. Coinbase Wallet comes with the following networks already configured, however you can add other EVM-compatible networks manually as well: Arbitrum. Avalanche C-Chain.
The USDT on Coinbase is an ERC20 token on the Ethereum blockchain. At this time, Coinbase does not support the Tron blockchain TRC USDT.
ERC20 is only available through Coinbase Wallet. Assets on Coinbase Wallet are not held by Coinbase.
According to Coinbase: BEP20 tokens have a similar address format as Ethereum and share the same properties of the ERC20 standard, however, they are not the same. BEP20 tokens are on a separate network, which Coinbase currently does not support.
Coinbase doesn't currently support Binance Chain (BEP-2) because it's a separate blockchain that isn't integrated with our platform. BEP-2 is a blockchain created by Binance specifically for their customers to send assets more quickly.
Bitcoin Networks is not supported by Coinbase.
Coinbase Commerce supports USDC, WETH (wrapped ETH), and MATIC payments on Polygon. In addition to making transactions faster and cheaper for your customers, Polygon reduces network fees for you to withdraw or refund transactions. You can manage your enabled assets and networks from the Payments tab of your Settings.
A simple rule of thumb is to always select the coin's native network. For example: BTC should be sent to your Ledger Bitcoin address via the BTC/Bitcoin network. ETH and ERC20 tokens should be sent to your Ledger Ethereum address via the ETH/ERC20 network.
TRON is not currently supported across Coinbase's vast ecosystem. There are still ways you can find a way to buy TRON.
Important note: at this time, Coinbase only supports USDT on the Ethereum blockchain (ERC-20). Do not send USDT on any other blockchain to Coinbase.

SONM (BEP-20) is not currently supported across Coinbase's vast ecosystem. There are still ways you can find a way to buy SONM (BEP-20).

BEP20 tokens have a similar address format as Ethereum and share the same properties of the ERC-20 standard, however, they are not the same. BEP20 tokens are on a separate network called Binance Smart Chain, which Coinbase Commerce currently does not support.
If you are looking for ease of development and want to benefit from the global exposure, reach and popularity of Ethereum, ERC20 token development is the best for you. However, if you want the best most innovative token with the lowest fee and processing time, choose BEP-20 token development.
