Wallet 2.0 does not work: initiate_tx method not found -- Solution?

Tech Support
1

The 2.0 wallet API is documented here: https://docs.rs/grin_wallet_api/1.1.0-beta.1/grin_wallet_api/trait.OwnerRpc.html#tymethod.initiate_tx

You can see according to the documetnation there is an “initiate_tx” method. However, when actually trying to utilize said method the RPC call returns an error: “Method not found”.

Does anyone know what the solution is?

EDIT: created issue for it here: https://github.com/mimblewimble/grin-wallet/issues/170

Issue discovered. In wallet 2.0 the v2.0 RPC API changed again. The method renamed to “init_send_tx”. However, there is another issue. The “send_args” does not work. Any ideas?

{
“args”: {
“src_acct_name”: null,
“amount”: “1000000000”,
“max_outputs”: 500,
“minimum_confirmations”: 10,
“num_change_outputs”: 1,
“selection_strategy_is_use_all”: true,
“message”: “my message”,
“target_slate_version”: null,
“send_args”: {
“method”: “http”,
“dest”: “http://127.0.0.1:3415”,
“finalize”: true,
“post”: true,
“fluff”: true
}
}
}

{
“error”: {
“code”: -32602,
“message”: “InvalidArgStructure “args” at position 0.”
},
“id”: 6,
“jsonrpc”: “2.0”
}

You’re looking at the 1.1.0 documentation in the linked issue. “post”: true above should be ‘post_tx’

Apologies for changes, the API should remain relatively stable from 2.0.0 onwards

Grinmint, F2Pool and others all have a statement saying “We do not support the 2.0 Grin at this time, please use the old one.” Are pools just refusing to adopt. What’s the problem?
