Class: SolanaChainSigner

Defined in: solana-client/src/chain-signer.ts:27

Solana implementation of OvercastChainSigner. From a SolanaConfig it resolves the signing keypair and builds the shared connection / provider / Anchor program, then signs and confirms the transactions an SolanaWriter builder produces.

The program it holds is the same one the builder should run against, so the fee payer the builder bakes into each transaction (provider.publicKey) and the key this signer signs with are guaranteed to match.

A config without a privateKey yields a read-only signer: the connection / provider / program are still built (so the SolanaReader and any other read path work), but publicKey and submit throw — there is no key to identify a wallet or sign a transaction with.
