Solana Transaction Parser Demo

Example usage of @debridge-finance/solana-transaction-parser with and without a custom instruction decoder for the Swift Auction program.

What’s inside

• Parse a real mainnet transaction with the default parser.
• Attach a custom decoder for the Swift Auction program and print decoded instruction args.
• Demonstrate IDL-driven decoding and a manual binary parser for OrderInfo (Mayan Swift Auction Object).

Project layout

• src/no-custom-decoder.ts: parse a transaction using only the default parser.
• src/auction-custom-decoder.ts: parse the same transaction with a custom decoder.
• src/custom-parsers/swift-auction-parser.ts: custom decoder for the bid instruction.
• src/decodeOrderInfo.ts: manual binary decoder for OrderInfo.
• src/idl/swift_auction.json / swift_auction.ts: program IDL + type definitions.

Requirements

• Node.js 18+ (recommended)
• npm

Install

1. Install dependencies:

   npm install

2. Install a TypeScript runner (one-time):

   npm install -D typescript ts-node

Run the examples

Default parser

npx ts-node src/no-custom-decoder.ts

Custom Swift Auction decoder

npx ts-node src/auction-custom-decoder.ts

Notes

• The examples use a mainnet transaction hash hard-coded in the scripts.
• The custom decoder only handles the bid instruction selector and can be extended.
