Overview​

This section details how to derive an ICP adress using the Rosetta construction API. The ICP ledger is using accountidentifiers to represent public keys internally. To derive an accountidentifier from a public key the Rosetta API offers the construction/derive endpoint. The request and response types can be found in the official documentation.

How to derive accountidentifiers​

You have to provide Rosetta with the public key representation as specified in the Rosetta-API standard. An example of a call to the derive endpoint can be found below:

curl --location '0.0.0.0:8081/construction/derive'  --header 'Content-Type: application/json' --data '{
    "network_identifier": {
        "blockchain":"Internet Computer",
        "network":"00000000000000020101"
    },
    "public_key": {
    "hex_bytes": "047a83e378053f87b49aeae53b3ed274c8b2ffbe59d9a51e3c4d850ca8ac1684f7131b778317c0db04de661c7d08321d60c0507868af41fe3150d21b3c6c757367",
    "curve_type": "secp256k1"
  }
}'

The response is the accountidentifier used by the ICP ledger:


{"account_identifier":{"address":"8b84c3a3529d02a9decb5b1a27e7c8d886e17e07ea0a538269697ef09c2a27b4"}}⏎
