If you want to retrieve the ICP that was locked in the neuron, you will have to set the neuron to a dissolving state. You must wait at least 6 months between setting the neuron to DISSOLVING and receiving back your ICP. The waiting period increases if the set dissolve timestamp is further in the future than 6 months.

Start dissolving

To set a neuron to DISSOLVING you can build the following payloads request:

curl --location '0.0.0.0:8081/construction/payloads'  --header 'Content-Type: application/json' --data 
'{
  "network_identifier": {
    "blockchain": "Internet Computer",
    "network": "00000000000000020101"
  },
  "public_keys": [
    {
      "hex_bytes": "047a83e378053f87b49aeae53b3ed274c8b2ffbe59d9a51e3c4d850ca8ac1684f7131b778317c0db04de661c7d08321d60c0507868af41fe3150d21b3c6c757367",
      "curve_type": "secp256k1"
    }
  ],
  "operations": [
    {
      "operation_identifier": {
        "index": 0
      },
      "type": "START_DISSOLVING",
      "account": {
        "address": "8b84c3a3529d02a9decb5b1a27e7c8d886e17e07ea0a538269697ef09c2a27b4"
      },
      "metadata": {
        "neuron_index": 0
      }
    }
  ],
  "metadata": null
}'

After that, you can fetch the neuron info and it should display that it is now in DISSOLVING state.

{
    "transaction_identifier": {
        "hash": "0000000000000000000000000000000000000000000000000000000000000000"
    },
    "metadata": {
        "operations": [
            {
                "account": {
                    "address": "8b84c3a3529d02a9decb5b1a27e7c8d886e17e07ea0a538269697ef09c2a27b4"
                },
                "metadata": {
                    "controller": "iowfl-yzooa-br3dt-77erl-nlm7f-kplhq-php75-hw3an-aeqn2-swh4t-3qe",
                    "followees": {},
                    "hotkeys": [],
                    "kyc_verified": true,
                    "maturity_e8s_equivalent": 0,
                    "neuron_fees_e8s": 0,
                    "neuron_id": 3094748712371737240,
                    "neuron_index": 0,
                    "staked_maturity_e8s": null,
                    "state": "DISSOLVING"
                },
                "operation_identifier": {
                    "index": 0
                },
                "status": "COMPLETED",
                "type": "NEURON_INFO"
            }
        ]
    }
}

Stop dissolving

To stop a neuron from dissolving, you can call Rosetta with the following parameters:

curl --location '0.0.0.0:8081/construction/payloads'  --header 'Content-Type: application/json' --data 
'{
  "network_identifier": {
    "blockchain": "Internet Computer",
    "network": "00000000000000020101"
  },
  "public_keys": [
    {
      "hex_bytes": "047a83e378053f87b49aeae53b3ed274c8b2ffbe59d9a51e3c4d850ca8ac1684f7131b778317c0db04de661c7d08321d60c0507868af41fe3150d21b3c6c757367",
      "curve_type": "secp256k1"
    }
  ],
  "operations": [
    {
      "operation_identifier": {
        "index": 0
      },
      "type": "STOP_DISSOLVING",
      "account": {
        "address": "8b84c3a3529d02a9decb5b1a27e7c8d886e17e07ea0a538269697ef09c2a27b4"
      },
      "metadata": {
        "neuron_index": 0
      }
    }
  ],
  "metadata": null
}'

The corresponding state of the neuron will switch to `NOT_DISSOLVING`.

    "transaction_identifier": {
        "hash": "0000000000000000000000000000000000000000000000000000000000000000"
    },

            }
        ]
    }
