Where to buy Synapse in Spain

Since 1 July 2026 only platforms authorised under MiCA may operate in Spain. These ones are and have the pair open — two different things, and both worth checking. You can verify the authorisation yourself in the register we keep up to date:

Is this your first purchase? Before opening an account, read how to buy cryptocurrency in Spain step by step: the right order, what they will ask you for and what you pay extra if you press the wrong button.

  • Bitvavo — SYN/EUR. You can pay in euros. Bitvavo B.V., authorised by Netherlands Authority for the Financial Markets (AFM) since 06/2025.
  • Kraken — SYN/USD. No euro pair: you would have to swap into another coin first, and that swap is taxable in Spain. Payward Europe Solutions Limited, authorised by Central Bank of Ireland (CBI) since 06/2025.

Being authorised does not mean they are the best option for you: it means they may operate legally. Fees and service are something you have to look at separately. This is not investment advice.

Availability checked on 14/09/2026. We cannot say either way for Bitpanda: it does not publish its list of trading pairs.

And when you sell at a profit, it has to be declared: work out what you pay in Spanish income tax using the FIFO method the tax office requires. And if you hold more than €50,000 on platforms outside Spain, you also have to file form 721, which is informational and costs nothing.

What is Synapse

Synapse trades under the ticker SYN and ranks #451 by market capitalisation in the CoinGecko catalogue. It is a token issued on the Ethereum network, not a coin with a chain of its own. Its contract on that network is 0x0f2d719407fdbeff09d87557abb7232601fd9f29. It is also deployed on BNB Chain, Base and Polygon. CoinGecko lists it under cross-chain bridge governance, the BNB Chain ecosystem and the Avalanche ecosystem.

Project description from CoinGecko

Synapse is a cross-chain layer ∞ protocol powering frictionless interoperability between blockchains. By providing decentralized, permissionless transactions between any L1, sidechain, or L2 ecosystem, Synapse powers integral blockchain activities such as asset transfers, swaps, and generalized messaging with cross-chain functionality - and in so doing enables new primitives based off of its cross-chain architecture. At Synapse you can bridge and swap stable assets between chains and provide liquidity to fuel cross-chain swapping in pools with minimal impermanent loss.

Frequently asked questions about Synapse

Synapse is a cross-chain layer ∞ protocol powering frictionless interoperability between blockchains. By providing decentralized, permissionless transactions between any L1, sidechain, or L2 ecosystem, Synapse powers integral blockchain activities such as asset transfers, swaps, and generalized messaging with cross-chain functionality - and in so doing enables new primitives based off of its cross-chain architecture. At Synapse you can bridge and swap stable assets between chains and provide liquidity to fuel cross-chain swapping in pools with minimal impermanent loss.

Four steps: open an account with a provider authorised to operate in Spain, verify your identity, deposit euros by SEPA transfer and buy Synapse in the matching pair. If you plan to hold for a long time, consider withdrawing to a wallet you control: moving your coins to your own custody is not a sale, so it is not taxed. Selling Synapse at a profit is, and you can work out how much.

You can buy it with euros on Bitvavo (SYN/EUR). It also trades on Kraken (SYN/USD), but with no euro pair: you would have to swap into another coin first, and that swap is taxable in Spain. Checked on 14/09/2026. We cannot say either way for Bitpanda: it does not publish its list of trading pairs.

Why you will not find a price prediction here

There is no method that reliably predicts the price of a cryptocurrency. It depends on regulation, on adoption, on interest rates, on the decisions of a handful of very large firms and on market sentiment — none of which follows from today's price. A figure twelve months out would not be analysis: it would be an invented number that looks like data.

What you can look at is right above, and it is verifiable: the all-time high and low with their dates, how far away each one is and the recent path. With that you decide for yourself, which is rather more than a figure with nothing behind it gives you.
