Tip to enter and exit crypto without fee, for Eurozone people

u/WackySnaky made me discover Monerium a few days ago

On Monerium you can create for free an Estonian IBAN linked to an EVM adress. (with KYC ofc)

When this IBAN gets euros through SEPA transfer, the fiat euro is automatically converted into EURe on the associated adress at a perfect 1:1 ratio. For now at least there isn't any fee.  

You can reconvert into fiat euro whenever you want by making a SEPA transfer towards a traditional bank account.

EURe is a native token on EVM networks, but not on Solana.

You can move funds between some EVM networks (Arbitrum for example) and Solana without loss by using Circle's CCTP bridge for USDC in Noble Express.  

So there are some fees between EURe and USDC on Solana: the networks gaz fees, and the swap between EURe and USDC.

The most cost-effective solution I found is CowSwap on Arbitrum.

Arbitrum has low gaz fees, and the fee for limit orders on CowSwap is very small (0.02% of the transaction).  

If you are in hurry you can also make a spot exchange instead of a limit order, but the slippage looked quite big.

If you know a cheaper way to get stablecoins on Solana, let me know in the comment!
