Operator & jurisdiction: BASIS is operated by BASIS DIGITAL INFRASTRUCTURE LTD, a Seychelles-incorporated entity (LEI: 254900IX2F2KCWNSSS64).
This guide explains how to deposit Ethereum (ETH) into BASIS.
1. Overview
ETH deposits are made by connecting a Web3 wallet such as MetaMask and sending ETH on Ethereum Mainnet.
After your deposit is credited to your Funding Wallet, you may swap ETH to stETH at a 1:1 ratio, less the swap fee. Staking rewards accumulate in real time as stETH in your Staking Wallet.
[!IMPORTANT] ETH deposits do not convert to USDT.
USDT is used only as an internal accounting and display unit. It is not depositable or withdrawable.
ETH can only be swapped to stETH on a same-token 1:1 basis.
