What it means

Assembling, compiling, signing and size-checking transaction messages.

What to do

  • Set a fee payer and a lifetime (blockhash or durable nonce) before compiling.
  • Keep the serialised transaction at or under 1,232 bytes; use address lookup tables for large transactions.
  • A durable-nonce transaction must have AdvanceNonceAccount as its first instruction.

npx @solana/errors decode -- 5663017 '<base64 context>'

In development, import from @solana/kit as usual and the full message is thrown. In production the message is stripped to keep bundles small; the error object still carries error.context with the same values this page decodes, and isSolanaError(err, SOLANA_ERROR__TRANSACTION__MESSAGE_SIGNATURES_MISMATCH) lets you branch on it.
