@kamino-finance/api-utils

Protobuf codecs for Solana instructions and address lookup tables, encoding to and from @solana/kit types.

import {
  encodeInstruction,
  decodeInstruction,
  encodeAddressLookupTable,
  decodeAddressLookupTable,
} from '@kamino-finance/api-utils';

const bytes = encodeInstruction(instruction); // kit Instruction -> Uint8Array
const same = decodeInstruction(bytes); // Uint8Array -> kit Instruction

Each message is encoded on its own, so an API groups and orders instructions in its own JSON, typically as arrays of base64 strings.

Errors throw as InstructionCodecError with a code of MISSING_PUBKEY, INVALID_PUBKEY_LENGTH or INVALID_WIRE_BYTES. Discriminate on code rather than instanceof, which is not stable across the ESM and CommonJS builds.

Requires @solana/kit ^5 or ^6 as a peer dependency.
