txdecoder

txdecoder.xyz helps you decode on-chain transactions across Ethereum, Solana, BNB Chain, and Base into a single unified, human-readable schema.

Instead of dealing with raw logs, instruction bytes, or chain-specific formats, txdecoder normalizes everything into a clean data structure that is easy to query, index, and analyze.

🚀 Playground (Try it now)

👉 https://txdecoder.xyz/#public

Paste a transaction hash from any supported chain and instantly see:

• Raw on-chain data
• Decoded actions (swap, transfer, mint, borrow…)
• Unified, human-readable schema output

No setup. No SDK. Just on-chain data → readable structure.

✨ Why txdecoder?

Decoding on-chain transactions is painful because:

• Each chain has different execution models
• Data is scattered across:
  • Logs
  • Instructions
  • Internal calls
  • Program-specific layouts
• Output is not human-readable
• Cross-chain analytics becomes extremely hard

txdecoder solves this by converting raw transactions into a single unified schema.

🧠 What txdecoder does

txdecoder takes a raw on-chain transaction and produces:

• High-level actions (swap, transfer, mint, borrow, liquidate…)
• Normalized entities
  • user
  • protocol
  • pool / market
  • token
• Unified fields across all chains
• Human-readable semantics
