Convert Stake Key to Address

Question

I am tiring to use Cardano Sterilization Lib to get the Stake/Usable address from Stake Hash or Address Hash.

Address Hash: 01daaf711704003ec3d62ba63ab7fc82c52fdfadbe4a34e97158cafe5098ab0c9333611bee9b2e58f6daa99f237d173e0c7af6a7a203d6be27

Stake Key Hash: e198ab0c9333611bee9b2e58f6daa99f237d173e0c7af6a7a203d6be27

I saw Convert xpub public key from ccvault to bech32 or acct_ public key which showed a way but I couldn't get it to work.

wasm.StakeCredential.from_bytes(new TextEncoder().encode("98ab0c9333611bee9b2e58f6daa99f237d173e0c7af6a7a203d6be27"))

returns Deserialization failed in StakeCredential because: Invalid cbor: not the right type, expected Array' byte received Text'.

Thanks!

Answer 1

You can try with this line:

wasm.StakeCredential.from_bytes(
 Buffer.from("98ab0c9333611bee9b2e58f6daa99f237d173e0c7af6a7a203d6be27", "hex")
)

Alternatively, you can try using from_keyhash method. This method expects to receive a Ed25519KeyHash, which you can build from the given Stake Key Hash, all in the same instruction, like this:

wasm.StakeCredential.from_keyhash(
 wasm.Ed25519KeyHash.from_bytes(
  Buffer.from("e198ab0c9333611bee9b2e58f6daa99f237d173e0c7af6a7a203d6be27", "hex")
 )
)
