Load it

import { useBlockchain, blockchains } from "@agntn/keys";

const solanaChain = useBlockchain(await blockchains.solana()());

The address

const publicKey = solanaChain.getKeyPublic(privateKey); // 32 bytes, 64 hex chars
solanaChain.getAddress(publicKey); // base58 of the same 32 bytes

No hash, no version byte, no checksum. The address is the public key with a friendlier encoding. It makes Solana the easiest chain in the package and the one where validateAddress can say the least: any 32 bytes that decode from base58 pass, including a program address that no private key controls.

Validation

solanaChain.validateAddress("9xQeWvG816bUx9EPjHmaT23yvVM2ZWbrrpZb9PusVFin"); // true

Decodes as base58 and is exactly 32 bytes. That is the whole check.

Mnemonics

Solana derives with SLIP-10, which only has hardened children. Every segment of the path needs the tick:

solanaChain.deriveHDWallet(mnemonic, "m/44'/501'/0'/0'").address;

A path with an unhardened segment throws before derivation. Phantom and Solflare use exactly this shape, so the first account matches what those wallets show.

Signing

signMessage is a plain ed25519 signature over the message bytes, hex encoded, and verifyMessage checks it against the public key. That is the format nacl.sign.detached produces, minus the base58 wrapper some wallets add on top.
