• 10 clients.
  • Each client has his own wallet on my secured system.
  • An API service manages these wallets.

Leading Questions:

  • Each wallet should run as a separate process of "bitcoind"?
  • If so, each "bitcoind" can use the same blockchain files?
  • There is a best practice of running multiple wallets on the same system?
  • 0.17 (and I think 0.16) has support for multiple wallets in one bitcoind. Even runtime adding/removing/switching wallets. You can manage those using RPC commands. Multiple bitcoind instances can not share the same blockchain files. No experience with this, so can't comment on best practices.

1 Answer 1


Using multiple wallets on one "bitcoind" process

Follow this steps:

  1. Run the bitcoind process.
  2. Create a wallet for each of the clients using:

bitcoin-cli.exe createwallet <client_uniq_id>

  1. When you want to perform any action on any wallet simply use:

bitcoin-cli.exe -rpcwallet=<client_uniq_id> <your_rpc_method>

  1. Use "" for <client_uniq_id> in order to refer to the default wallet, created by the bitcoind.
  • your solution do not specify if running two instances will utilize two copies of the blockchain or use the same ? Also, will this procedure run two wallets simultaneously or only one instance can run at any given moment ? Thanks Sep 28, 2020 at 15:52
  • How should I use it with json-rpc? There is no wallet_name parameter in send not list_transactions. So is it possible to run 2 wallets concurrently? So I send coins from one wallet and receive it in another but having just one blockchain and not doing service restart or wallet unload/load between? May 24, 2022 at 13:58
