LayerZero Bridged Sei wallet

What is LayerZero Bridged Sei (SEI)?

This SEI is a bridged representation, not the coin that runs the Sei network. LayerZero's bridge locks or burns SEI on one side and issues a matching token on the other, and what you hold on Ethereum is that issued side: an ERC-20 whose supply is tied to the amount held against it.

Three consequences worth internalising.

It pays no fees on Sei. Native SEI is the gas coin of its own chain; the bridged ERC-20 cannot pay for anything there. Ethereum transactions involving it cost ETH, so ETH has to be in the same wallet.

The ticker is identical. On a screen, bridged SEI and native SEI read exactly the same. The difference is only the chain, and that is the detail a deposit address depends on. Sending this token to an address that expects native SEI does not deliver SEI there.

Crossing back is a bridge operation. Moving to the Sei network means going through the bridge, waiting for it to confirm on both sides, and receiving native SEI at a Sei address, which has a different format from an Ethereum one.

Supported networks in Tangem (1): Ethereum. What Tangem gives you here is a clear statement of which network the outgoing transfer belongs to, shown before the card signs. Confirming that the recipient wants the Ethereum version is your job and no software can settle it, because an address alone carries no indication of the chain behind it. Holding a bridged token where the chain is always spelled out is the habit worth keeping.
