Grin exchanges

Grin is so new that prices can differ significantly between exchanges. Some exchanges such as hotbit no longer allow withdrawals.

Bittrex has much higher price but requires a wallet file to be created by the grin linux client to accept a deposit. allows direct withdrawal with the account address.

Grin Wallet Files

Here are instructions on how to use grin-wallet. Note that grin-wallet needs to be built separately from grin server now.

Let's say Alice wants to send funds to Bob:

  • Alice: types: grin wallet send -m file -d my_grin_transaction.tx 100
  • Bob: grin wallet receive -i my_grin_transaction.tx, and bob send generated my_grin_transaction.tx.response to Alice
  • Alice types: grin wallet finalize -i my_grin_transaction.tx.response

Transaction is highly interactive.
