How it works

Fastspot is the infrastructure and liquidity provider for super secure and non-custodial currency swaps.

Empowered by Nimiq OASIS, you can swap BTC-EUR and NIM-EUR, more to be added.

Fastspot makes a quote for user demand

The price is determined from live market data across various exchanges.

Fastspot sends NIM to automated escrow

The automated escrow (HTLC) ensures only the user can retrieve the NIM once they receive access to a secret. NIM are returned after pre-defined time if secret is not provided.

User transacts EUR to automated escrow

The escrow for EUR is the regulated Nimiq OASIS service provided by TEN31 Bank and can be publicly verified.

Nimiq OASIS ensures that EUR are only transferred to Fastspot if the secret of the NIM HTLC is provided and otherwise are sent back to the user after a pre-defined time.

Fastspot reveals the secret

By publishing the secret and thereby providing it to Nimiq OASIS, Fastspot retrieves the EUR from the automated escrow.

User's wallet retrieves NIM

Using the secret published by Fastspot, the user's wallet can retrieve the NIM from the escrow (HTLC).

Swap finished

The user receives their NIM at the previously agreed rate without having to give custody of their funds to Fastspot.
