How people use Blackpool
Principle
“No fixed denominations, no mixer queues, no waiting periods. Any amount, whenever you want it back.”
Pool design2-in / 2-out shielded notes with change
Principle
“Your signature derives everything. No private key or signature is ever sent to a server.”
Non-custodialProof inputs and burner keys stay in your browser
Principle
“The relayer pays the gas, so the paying wallet is never yours.”
Relayer-built transactionsFlat fee taken from the note itself
Principle
“Bridges should not know who is on the other side. Intents keep the recipient off the origin chain.”
NEAR Intents routingOne-off solver deposit address per transfer
Principle
“If a step fails, the money is still yours. Every burner and bridge is recoverable from any device.”
