View Source Signet.Solana.Signer.Ed25519 (Signet v1.6.0)

Ed25519 signing backend using a local private key seed.

Uses OTP :crypto directly (available since OTP 24). This is the Solana equivalent of Signet.Signer.Curvy for Ethereum.

Examples 

iex> seed = Base.decode16!("9D61B19DEFFD5A60BA844AF492EC2CC44449C5697B326919703BAC031CAE7F60")
iex> {:ok, sig} = Signet.Solana.Signer.Ed25519.sign("hello", seed)
iex> byte_size(sig)
64

sign(message, arg)

View Source 
@spec sign(binary(), <<_::256>>) :: {:ok, <<_::512>>}

Sign message bytes with the given 32-byte seed.

Ed25519 handles hashing internally (SHA-512), so the message is signed as raw bytes with no external digest step.

Returns {:ok, signature} where signature is exactly 64 bytes.

Examples 

iex> seed = Base.decode16!("9D61B19DEFFD5A60BA844AF492EC2CC44449C5697B326919703BAC031CAE7F60")
iex> {:ok, sig} = Signet.Solana.Signer.Ed25519.sign(<<>>, seed)
