On Secure Swap, a predefined list of tokens will be listed at launch.

A NodeOwner (node operator) can unlist the tokens of his choice. These tokens will then no longer be processed by his nodes.
If a token is specifically unlisted on more than 50% of the connected gateway nodes, then the unlisting automatically spreads to all nodes, and to all those that would later connect, causing the global unlisting of this token.

It is also mandatory that more than 50% of NodeOwners either:
- manually cancel the unlisting, or
- add the token to the list on their node
so that the token is listed again on all nodes, by propagation.

A minimum of three nodes that support a token or a coin is required for exchanges to be possible on Secure Swap.

For coins, only three connected gateway nodes supporting them are required for the coins to be listed. It is also necessary that the client plugin that manages this coin wallet is available (either created by us or by the team that develops this coin).

This described mechanism is valid for all supported blockchains.
