# Swap for $SGR (ERC20) on DEX and bridge to aelf dAppChain (tDVV)

If you wish to buy $SGR from a decentralised exchange, first swap for $SGR on [Uniswap](https://app.uniswap.org/swap?outputCurrency=0x478156deabfac918369044d52a6bdb5cc5597994). Then, using the dApp [eBridge](https://ebridge.exchange/), bridge $SGR from Ethereum (ERC20) to aelf's dAppChain (tDVV).\
